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.).
Final Guideline Release: This guideline is available from the U.S.
Government Printing Office, Washington, DC 20402 on disks or paper
copies: call (202) 512-0132. This guideline is also available electronically
in PDF (portable document format) from EPA's World Wide Web site
(http://www.epa.gov/opptsfrs/home/guidelin.htm) under the heading "In-
formation Sources/Test Methods and Models/OPPTS Harmonized Test
Guidelines."
-------
OPPTS 830.7300 Density/relative density/bulk density.
(a) Scope—(1) Applicability. This guideline is intended to meet test-
ing requirements of both the Federal Insecticide, Fungicide, and
Rodenticide Act (FIFRA) (7 U.S.C. 136, et seq.) and the Toxic Substances
Control Act (TSCA) (15 U.S.C. 2601).
(2) Background. The source materials used in developing this har-
monized OPPTS test guideline are the OPPT guideline under 40 CFR
796.1150 Density/relative density, OPP guideline 63-7 Density, bulk den-
sity, or specific gravity (Pesticide Assessment Guidelines, Subdivision D:
Product Chemistry, EPA Report 540/9-82-018, October 1982) and OECD
guideline 109 Density of Liquids and Solids.
(b) Introduction. This test guideline references methodology to de-
velop data on density, relative density (specific gravity), and bulk density
of chemical substances and mixtures. The data may be used to evaluate
the manner and extent that chemicals will be transported in the environ-
ment and the places they will be deposited.
(c) Test procedures. Examples of methods for determining density
and relative density of gaseous, liquid, or solid chemical substances are
listed in Table I, "Standard Density - Measurement Techniques Ref-
erenced in this Guideline" and in OECD Guideline No. 109 (OECD 1995),
"Density of Liquids and Solids." Bulk density may be determined by
using methods outlined in ASTM D-729 or CIPAC MT 159. If bulk den-
sity cannot be accomplished due to the nature of the solid, conduct relative
density studies using a standard method such as CIPAC MT-3. The codes
to standardizing bodies listed in table I are:
ANSI—American National Standards Institute; ASTM—American
Society for Testing and Materials; BSI—British Standards Institution; IP—
Institute of Petroleum; CIPAC—Collaborative International Pesticides An-
alytical Council; DIN—Das 1st Norm (earlier Deutsche Industrienormen);
API—American Petroleum Institute; ISO—International Organization for
Standardization; OECD—Organization for Economic Cooperative and De-
velopment.
