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 830.6303 Physical state.
(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 63-3 Physical state (Pes-
ticide Assessment Guidelines, Subdivision D: Product Chemistry, EPA Re-
port 540/9-82-018, October 1982) and 40 CFR 158.190 Physical and
chemical characteristics.
(b) Test method—(1) Objective. Data on the physical and chemical
characteristics of pesticide active ingredients and products are used to con-
firm or provide supportive information on their identity. Such data are
also used in reviewing the production or formulating process used to
produce the pesticide or product. Physical state, color, and odor are needed
for the Agency to respond to emergency requests for identification of
unlabeled pesticides involved in accidents or spills. Physicians, hospitals,
and poison control centers also request this information to aid in their
identification of materials implicated in poisoning episodes.
(2) Test details. The description of the physical state of each sub-
stance shall be based on a visual inspection of the substance at 20 °C
or 25 °C.
(c) Reporting. (1) Report the physical state including the form of
the substance. Conventional terms such as "solid," "granular," "semi-
solid," "crystalline solid," "amorphous solid," "mixture of liquid and
solid," "aqueous solution," "emulsion," "volatile liquid," "powder,"
"gas," and similar terms such as those used to describe compounds in
the "Handbook of Chemistry and Physics" (see paragraph (d) of this
guideline) shall be used, as appropriate, to describe each substance.
(2) Any methods used to characterize the physical properties of a
pesticide shall be referenced or described in the application for registration.
If the methods used are listed in paragraph (d) of this guideline, reference
to the method will suffice. If other methods are used, copies of such meth-
ods must be submitted with the application.
(d) References. The following references should be consulted for ad-
ditional background material on this test guideline.

Raton, FL, latest edition.
