WaterSense- Product Certification System Version 2.1
1.0 Introduction
WaterSense, a partnership program sponsored by the U.S. Environmental Protection Agency
(EPA), seeks to protect the future of our nation's water supply by offering people a simple way
to use less water with water-efficient products, new homes, and services. To achieve the
mission of the WaterSense program, EPA establishes partnerships with interested stakeholders.,
such as product manufacturers, retailers, and water utilities. EPA provides and maintains the
WaterSense brand and develops national specifications for water-efficient products and
programs.
EPA requires all products bearing the WaterSense label to be assessed for conformance to the
relevant WaterSense product specification by an accredited, independent, third-party product
certifying body. EPA will license accredited product certifying bodies to certify that products
conform to applicable specifications and to authorize the use of the WaterSense label in
conjunction with the certified product.
The international criteria for the accreditation of product certifying bodies operating product
certification programs for tangible products, processes, and services are detailed in International
Organization for Standardization/International Electrotechnical Commission (ISO/IEC) Guide 65,
General requirements for bodies operating product certification systems and the International
Accreditation Forum (IAF) Guidance on the Application of ISO/IEC Guide 65.17065, Conformity
assessment—Requirements for bodies certifying products, processes, and services.
This WaterSense Product Certification System (product certification system) specifies the
minimum requirements that EPA-licensed product certifying bodies (licensed certifying bodies)
shall observe when operating third-party certifications of product conformance to WaterSense
product specifications and authorizing the use of the WaterSense label. It provides specific
requirements in the application of ISO/IEC Guide 6517065 in order to satisfy the requirements
implicit in the certification of products for WaterSense and provides the basis for consistent
application of this product certification system by licensed certifying bodies.
This document, with respect to the certification and labeling of products for WaterSense, shall
be read in conjunction with ISO/IEC Guide 65 and IAF Guidance on the Application of ISO/IEC
Guido 65.17065.
The requirements of this product certification system are applicable to EPA-approved
accreditation bodies (approved accreditation bodies), licensed certifying bodies, and the
manufacturers that are obtaining product certification. Figure 1 (at the end of this document)
portrays the key elements of this product certification process and the relationships between
EPA, the manufacturer, the licensed certifying body, and the accreditation organization.
Certification by a licensed certifying body is not a statement that the licensed certifying body
guarantees the efficiency and performance of a WaterSense labeled product. It is also not a
guarantee that all of the aspects of a relevant WaterSense product specification are being met
or will continue to be met at all times. The certification and labeling of a product for WaterSense
is a statement that a product has been demonstrated to conform to the relevant WaterSense
product specification, and that the validation and verification of conformance to the WaterSense

month.
&57.6 Surveillance
To ensure that products continue to conform to the relevant WaterSense product specifications
and that manufacturers are properlymarking product packaging and using the WaterSense label
properly, EPA requires licensed certifying bodies to conduct periodic production inspection and
market surveillance of products as described below.
6t€t47.6.1 Periodic Production Inspection
The licensed certifying body shall, at a minimum, on an annual basis, audit the production
process and quality management of each manufacturer of a certified product(s). The purpose of
this audit shall be to:
• Verify that the manufacturer continues to operate production and quality
management in a manner that will maintain a product's conformance with relevant
WaterSense product specifications.
Consider and take appropriate action where changes to the manufacturer's
operations are made that may impact a product's conformance with relevant
WaterSense product specifications.
Sr&r27.6.2 Market Surveillance of Products
Except when the WaterSense product specification indicates otherwise, the licensed certifying
body shall conduct annual market surveillance, including product retesting and surveillance of
theproduct packaging marking and label use for the products it has certified. The licensed
certifying body shall appoint an inspector to conduct market surveillance of products. At the
licensed certifying body's discretion, samples for market surveillance shall be obtained from the
retail outlet/distribution center (including online retail/distribution sites) or project site where the
product is being sold or used, from the manufacturer's warehouse, or from off the line. Samples
may ©nly-be selected from off the line only when it is not feasible to obtain products from
another source. In such instances, the licensed certifying body shall notify EPA and provide
documentation as to why it was unable to obtain samples from one of the preferred sources.
Where purchase of the product is required, the manufacturer shall pay for the product.

The licensed certifying body shall conduct annual market surveillance on at least 15 percent of
all of the models it has certified for each relevant product category (e.g., tank-type toilets,
lavatory faucets, flushing urinals, showerheads).. Note that not every manufacturer will have
models retestedsubject to market surveillance each year. The number of models requiring
retestingsubject to market surveillance shall be based on the following criteria:
Only models that have not been tested or retested within the previous two years may be
subject to retestingmarket surveillance.
• PrivatelvPrivate labeled models shall not be counted as separate models from the
original manufacturer's models for this determination.
• Base models or families of products that demonstrate the same efficiency and
performanceT but that may have variations in color, finish, or other non-performance-
related attributes may be counted as a single model for this determination. Only one of
the models covered by the base model would be subject to retesting. market
surveillance.
By September 30 of each year, the licensed certifying body shall determine and provide EPA
with the full list of models that it has determined are eligible for market surveillance (in
accordance with this section) for all annual market surveillance activities to be conducted
between October 1 of that year and September 30 of the following year.
Of the 15 percent of eligible models, up to half (i.e., 7.5 percent of the eligible models) may be
designated for retestingmarket surveillance by EPA based on the following criteria:
Models that have previously failed market surveillance.
Preferred location, such as a retail outlet/distribution center.
Referrals from third parties, such as consumers, consumer groups, or regulatory
agencies regarding the accuracy of certifications.
Models with high sales volumes, if this data is available to WaterSense.
EPA will notify the licensed certifying body by November 1 of that year of the details of its
allotted designation. The remainder of the eligible models required to comprise the 15 percent
shall be randomly selected for retestingmarket surveillance by the licensed certifying body.
The licensed certifying body shall fetestevaluate a minimum of one model or the appropriate
number of models required to comprise the 15 percent retestingmarket surveillance
requirement, rounded to the nearest whole number, whichever is greater. If the licensed
certifying body determines that no products are eligible for annual retestingmarket surveillance
(e.g., all products have been tested within the previous two years), the licensed certifying body
does not need to fetestconduct market surveillance on any products.
The licensed certifying body shall determine and notify EPA of the number of models requiring
retesting by September 30 of each year for all annual market surveillance activities to be
conducted between October 1 of that year and September 30 of the following year. EPA will in
turn notify the licensed certifying body by November 1 of that year of the details of its allotted
designation.

All products selected for market surveillance shall be retested for conformance with the relevant
WaterSense product specification in accordance with Section 6.2.37.2.3 of this product
certification system.
As with the initial testing, if the licensed certifying body wishes to rely on otherwise available,
current test data generated during compliance testing to referenced ASME or other ANSI
standards for the purpose of retesting a product to the relevant WaterSense product
specification, the licensed certifying body shall document the technical justification supporting
the use of the otherwise available test data. The acceptance of otherwise available ASME or
other referenced ANSI standard test data shall consider the latest version of the referenced
standard(s) and any subseguent modifications that have been made to the product that would
affect its representativeness. The licensed certifying body shall not use otherwise available test
data that was generated more than five years prior to the date of retesting. The technical
justification shall include a statement concerning the validity of the otherwise available test data
and its applicability to the retested product's continued certification. Records of the technical
justification shall be maintained. WaterSense reserves the right to designate specific sections or
reguirements of the relevant product specifications that must be retested for a given product
category, regardless of whether such data is otherwise available.
All retesting shall be done by a licensed certifying body's internal resources or by an
independent testing laboratory or WMTL as described in Sections &Ar5.4. Use of an SMTL is
fiGt-permitted for productonly if the retesting is witnessed by the licensed certifying body.
&6A27.6.2.2 Surveillance of Product Packaging Marking and Label Use
All products selected for market surveillance shall also be assessed for proper product
packaging marking and use of the WaterSense label on product packaging and in advertising
materials, as described in the WaterSense Program Mark Guidelines and, if applicable, the
relevant WaterSense product specification. The licensed certifying body shall also verify that the
brand name and model number combination that appears on the product packaging matches

is to ensure that the products are being marked and labeled in accordance with WaterSense
program requirements and that the product's certification (identified by the unique brand name
and model number advertised) can be clearly traced.
657.7 Misuse of the Certification or WaterSense Label
The licensed certifying body shall take appropriate action, which can include label suspension or
withdrawal, when a product is found not to conform to the relevant WaterSense product
specification or when a manufacturer of a product it has certified engages in unauthorized,
incorrect, or misleading use of the certification or WaterSense label, whether the issue is
discovered by the licensed certifying body or is brought to its attention by another party.
Circumstances for unauthorized, incorrect, or misleading use of the certification or WaterSense
label are described in this product certification system, the WaterSense Program Guidelines,
and the WaterSense Program Mark Guidelines.
When issues related to product nonconformity or misuse of the WaterSense label come to
EPA's attention, EPA shall notify the licensed certifying body that authorized the use of
WaterSense label for the product in question. The licensed certifying body shall then engage in
investigation and resolution of the complaint in accordance with ISO/I EC Guide 65, IAF
Guidance on the Application of ISO/IEC Guide 65, and17065 and the licensed certifying body's
policies and procedures.
The licensed certifying body shall bring to EPA's attention any instances of unauthorized use of
a WaterSense label by a manufacturer of a product that it has not certified. EPA will engage in
appropriate corrective action with the infringing manufacturer.
Figure 2 (at the end of this document) outlines the mechanisms for identifying label misuse and
the party responsible for handling corrective actions (e.g., the licensed certifying body or EPA).
677.8 Suspension of the Use of the WaterSense Label on Products
The licensed certifying body shall determine when the use of the WaterSense label shall be
suspended due to product nonconformance, misuse of the WaterSense label, or infringement of
the product certification system. Label suspension can occur for a limited period of time as
specified by the licensed certifying body. During the period of suspension, the manufacturer is
prohibited from using the WaterSense label in conjunction with any product associated with the
suspended WaterSense label.
The licensed certifying body shall provide the manufacturer of a suspended WaterSense label
the conditions under which the suspension can be removed (i.e., corrective actions that shall be
taken). At the end of the suspension period, the licensed certifying body shall investigate
whether the indicated conditions for reinstating the WaterSense label have been fulfilled. Upon
receiving proof of fulfillment of these conditions, the licensed certifying body shall notify the
manufacturer that the suspension has been removed. The licensed certifying body shall notify

In more severe or repeated instances of product nonconformity, misuse of the WaterSense
label, failure to meet the requirements for reinstatement of a suspended WaterSense label, or
failure to maintain an active certification listing, the licensed certifying body shall withdraw the
product's certification and the use of the WaterSense label. The licensed certifying body shall
inform the manufacturer that the certification and WaterSense label are being withdrawn via a
withdrawal notification. If the WaterSense label is withdrawn from a product for any reason, the
licensed certifying body shall ensure that the manufacturer and its wholesalers, distributors, and
retailers immediately cease to use the mark in conjunction with that product, and the label is to
be eliminated from product packaging and promotional materials within six months from the date
of withdrawal notification. The licensed certifying body shall immediately notify EPA of any
product label withdrawals, and EPA shall decide whether termination of the partnership
agreement or other corrective action is warranted. The WaterSense label may not be used for
any reason by—or in conjunction with any product produced by—a manufacturer with a
terminated partnership agreement.
7vQ8.C Amendments, Modifications, and Revisions
EPA reserves the right to amend these rules of procedure, which may include amending or
revising this product certification system, revising any of the WaterSense product specifications,
or issuing technical clarifications as provided in the compendium of WaterSense product and
program specifications available on the WaterSense website. EPA also reserves the right to
make exceptions to these rules of procedure on a case-by-case basis, as necessary, and where
it is technologically reasonable.
Revisions to any of the WaterSense product specifications can occur due to technological
and/or market changes that affect the usefulness of current specifications to consumers,
industry, or the environment or to clarify vague requirements.
Major revisions to product specifications will generally include changes to the water efficiency or
performance requirements and/or related test methods. Major revisions will only be made
following an open public process, including discussion with industry and other interested
partners. Major revisions will typically require recertification of currently certified models to the
new specifications. The transition period will be identified in the relevant product specification,
but will normally be one year.
Minor revisions to product specifications will generally be more editorial in nature and serve to
clarify vague or unclear requirements. Minor revisions will typically not require recertification of
currently certified models. EPA will notify stakeholders when product specification revisions are
considered major or minor.
As deemed necessary, EPA also reserves the right to modify these rules of procedure as they
apply to specific categories of products. Any modifications will be identified at the release of the
product specification for the relevant product category.
To facilitate version control, EPA will designate a title, version number, and date for all of the
relevant documents it produces, as indicated below:

Models QRS and NOP are not eligible for retesting as of September 29, 2011A because they
were initially tested within the previous two years.
For models HIJ and A4B, which represent a family of models with variations in toilet color, only
one of the models within each of those families would be eligible for retesting.
Models 123, 456, 789, 987A, and 654A are privatelyprivate labeled models and should not be
counted as separate models from the original manufacturers' models. They may, however, be
selected for sampling to represent their respective original manufacturers' models.
From this list of 17 eligible models, three total models must be selected for retesting:
17 models * 15 percent = 2.55, which is rounded to 3 models
Of these three models, EPA reserves the right to designate one model for retesting:
17 models * 7.5 percent (half of the 15 percent total) = 1.3, which is rounded to 1 model
The licensed certifying body would randomly select the additional two models for retesting to
account for the remainder of the total number of models required to comprise the 15 percent:
3 total models for retesting - 1 model designated by EPA = 2 models randomly selected
by the licensed certifying body
Note: The licensed certifying body should not base the number of models it must retest on the
remaining percent of eligible products left after EPA's designation (e.g., 7.5 percent).
If EPA does not designate a model for retesting, the licensed certifying body would randomly
select all three models for retesting.
Figure 3 below illustrates how the licensed certifying body determines the number of models
that are eligible for annual market surveillance, how many models EPA may designate, and how
many models it is responsible for selecting.
