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
Basic Carbonate White Lead Pigment
This standard is issued under the fixed designation D81; 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 the material commercially known as basic carbonate white lead, used as a pigment and in putty.
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.

D1208 Test Methods for Common Properties of Certain Pigments
D1301 Test Methods for Chemical Analysis of White Lead Pigments
3. Composition and Properties
3.1 Dry Pigment—The pigment shall be free of adulterants and shall contain not more than traces of impurities incident to
well-controlled manufacture of high-grade basic carbonate white lead. The pigment shall conform to the following requirements:
Lead carbonate, % 62 to 75
Moisture and other volatile matter, max, % 0.7
Total other impurities, max, % 1.0
Coarse particles (total residue retained on a No. 1.0
325 (45-μm) sieve), max, %
3.2 Paste in Oil—The paste shall be made by thoroughly grinding the specified pigment with linseed oil. The paste 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, min, % 89
Linseed oil, max, % 11
Moisture and other volatile matter, max, % 0.7
Coarse particles and skins (total residue retained on a 1.5
No. 325 (45-μm) sieve), max, % of the dry
pigment
3.3 Semipaste Containing Volatile Thinner—The semipaste shall be made by thoroughly grinding the specified pigment with a
mixture of linseed oil and a small amount of volatile thinner. The semipaste shall not be caked in the container and shall be readily
stirred to a uniform mixture which shall mix readily with oil, turpentine, or volatile petroleum spirits to form a smooth paint of
brushing consistency. The odor of the semipaste, as taken from the container, while drying or after drying, shall be not abnormally
pungent or disagreeable. The semipaste shall conform to the following requirements:
