(Specification)Standard Specification for Red Lead Pigment
Standard Specification for Red Lead Pigment
ABSTRACT
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. Chemical analysis and coarse particle shall be tested to meet the requirements prescribed. Pigment, linseed oil, and moisture and other volatile matter in paste in oil shall be tested to meet the requirements prescribed.
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.

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, %:

85 % grade 85
95 % grade 95
97 % grade 97

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
