This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

Standard Specification for
Red Lead Pigment
This standard is issued under the fixed designation D83; the number immediately following the designation indicates the year of original
adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript
epsilon (´) indicates an editorial change since the last revision or reapproval.
ε NOTE—The units statement in subsection 1.2 was corrected editorially in July 2008.
1. Scope
1.1 This specification covers four grades of red pigment commercially known as red lead. The pigment may be purchased in
the dry form or as a paste in oil.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical
conversions to SI units that are provided for information only and are not considered standard.
2. Referenced Documents
2.1 ASTM Standards:
D49 Test Methods of Chemical Analysis of Red Lead
D185 Test Methods for Coarse Particles in Pigments
D1208 Test Methods for Common Properties of Certain Pigments
3. Composition and Properties
3.1 Dry Pigment—The pigment shall be made by roasting litharge or metallic lead, or compounds of lead that yield litharge by
heating, and shall consist entirely of oxides of lead, free of adulterants. The four grades of pigment shall conform to the following
requirements:
True red lead (Pb O ), min, %:
3 4
85 % grade 85
95 % grade 95
97 % grade 97
98 % grade 98
Total impurities including moisture, water soluble 1.0
matter, and matter insoluble in a mixture of
nitric acid and hydrogen peroxide, max, %
Lead monoxide, PbO remainder
Coarse particles (total residue retained on a 45-μm 1.0
(No. 325) sieve), max, %
When mixed as indicated in the following table, the resulting paint, brushed on a smooth vertical iron surface, shall dry hard
and elastic without running, streaking, or sagging:
Dry red lead 20 lb (9.1 kg)
Raw linseed oil 5 pt (2.4 L)
Turpentine 2 gills (0.24 L)
Liquid drier 2 gills (0.24 L)
3.2 Paste in Oil—The paste shall be made by thoroughly grinding the specified pigment with linseed oil (Note 1). The paste
as shipped by the seller, and for three months thereafter, shall not be caked in the container, and shall break up readily in oil to
form a smooth paint of brushing consistency. The paste shall conform to the following requirements:
Pigment, % 92 to 94
Linseed oil, % 6.0 to 8.0
Moisture and other volatile matter, max, % 0.5
Coarse particles and skins (total residue retained on 1.5
a No. 325 (45-μm) sieve), max, % of the dry pigment
