INTRODUCTION
This guideline is one of a series of test guidelines that have been
developed by the Office of Prevention, Pesticides and Toxic Substances,
United States Environmental Protection Agency for use in the testing of
pesticides and toxic substances, and the development of test data that must
be submitted to the Agency for review under Federal regulations.
The Office of Prevention, Pesticides and Toxic Substances (OPPTS)
has developed this guideline through a process of harmonization that
blended the testing guidance and requirements that existed in the Office
of Pollution Prevention and Toxics (OPPT) and appeared in Title 40,
Chapter I, Subchapter R of the Code of Federal Regulations (CFR), the
Office of Pesticide Programs (OPP) which appeared in publications of the
National Technical Information Service (NTIS) and the guidelines pub-
lished by the Organization for Economic Cooperation and Development
(OECD).
The purpose of harmonizing these guidelines into a single set of
OPPTS guidelines is to minimize variations among the testing procedures
that must be performed to meet the data requirements of the U. S. Environ-
mental Protection Agency under the Toxic Substances Control Act (15
U.S.C. 2601) and the Federal Insecticide, Fungicide and Rodenticide Act
(7U.S.C. I36,etseq.).

OPPTS 830.6320 Corrosion characteristics.
(a) Scope—(1) Applicability. This guideline is intended to meet test-
ing requirements of the Federal Insecticide, Fungicide, and Rodenticide
Act (FIFRA) (7 U.S.C. 136, et seq.}.
(2) Background. The source material used in developing this har-
monized OPPTS test guideline is OPP guideline 63-20 Corrosion charac-
teristics (Pesticide Assessment Guidelines, Subdivision D: Product Chem-
istry, EPA Report 540/9-82-018, October 1982) and 40 CFR 158.190
Physical and chemical characteristics.
(b) Test method—(1) Objective. Studies of the corrosion characteris-
tics of a pesticide are needed to evaluate effects of the product formulation
on the container. If the pesticide is highly corrosive, measures can be taken
to ensure that lids, liners, seams or container sides will not be damaged
and cause the contents to leak during storage, handling, or use. The objec-
tive of this guideline is to determine the effect of the pesticide product
on its packaging material.
(2) Method. Report the data on corrosion characteristics by following
the instructions in ASTM G-31. The registrant is urged to consult with
the Agency prior to adopting an alternative method.
(3) Combined testing. A study of the corrosion characteristics of a
product may be performed in combination with the storage stability test
described in OPPTS 830.6317.
(c) Reporting. (1) Report the corrosion characteristics of products
commercially packaged in metal, plastic, or paper containers in terms of
visual observations (e.g./'perforations," "darkening," "leaking or rust at
the seam," etc.) and, if corrosion is visually evident, by galvimetric or
other determinations of the container at the beginning and end of the stor-
age period (typically 1 year).
(2) Any methods used to characterize the physical properties of a
pesticide shall be described in the application for registration and copies
of such methods must be submitted with the application.
(3) The applicant shall submit his own statistical evaluation of the
precision and accuracy of these measurements (e.g., standard deviations
or confidence intervals) when appropriate.
