ASTM D1199-86(2014)

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.
Designation: D1199 − 86 (Reapproved 2008) D1199 − 86 (Reapproved 2014)
Standard Specification for
Calcium Carbonate Pigments
This standard is issued under the fixed designation D1199; 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.
This standard has been approved for use by agencies of the U.S. Department of Defense.
1. Scope
1.1 This specification covers two types of high-content calcium carbonate pigments, as follows:
1.1.1 Type PC—Calcium carbonate precipitate, prepared either by complete solution or by carbonation of lime.
1.1.2 Type GC—Ground mineral product.
1.2 Six grades of pigments, based on particle size (see 3.3) are covered.
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

3. Composition and Properties
3.1 The pigment may be prepared by chemical precipitation or by the fine grinding of natural calcium carbonate containing
minerals. If additional agents are used or any surface treatment is given, their purpose shall be indicated; acceptance shall be as
agreed upon by the purchaser and the seller.
3.2 Composition—The pigment shall conform to the requirements for composition prescribed in Table 1.
3.3 Fineness—The pigment shall conform to the following general requirements for fineness for the grade specified:
3.3.1 Grade I (Fine Paint Grade)—This grade possesses substantial amounts of material in the fine sizes, and is in general
essentially below 15 to 20 μm maximum size. Coarse particles retained on the No. 325 (45-μm) sieve shall be less than 0.05 %.
The maximum Specific Surface Diameter (SSD) shall be 2.5 μm.
3.3.2 Grade II (Coarse Paint Grade)—This grade is characterized by substantial amounts in the 5- to 45-μm range, and is lower
in pigment value than Grade I. Coarse particles retained on the No. 325 (45-μm) sieve shall be less than 0.5 %. The maximum SSD
shall be 6 μm.
3.3.3 Grade III (Filler Grade)—This grade is characterized by substantial amounts in the 10- to 45-μm range but with the coarse
particles retained on No. 325 (45-μm) sieve less than 25 % and a maximum SSD of 9 μ m. μm.
3.3.4 Grade IV (Putty Powder Grade) This grade possesses less fines, and have substantial amounts of coarse particles. The
coarse particles, however, shall not exceed 30 % retained on the No. 200 (75-μm) sieve. The maximum SSD shall be 12 μm.
This specification is under the jurisdiction of ASTM Committee D01 on Paint and Related Coatings, Materials, and Applications and is the direct responsibility of
Subcommittee D01.31 on Pigment Specifications.
