3. Composition and Properties
3.1 The pigment shall be made by burning natural gas (Type I) or oil (Type II) in such a manner as to form a deposit of carbon. It shall be free of adulterants and be in the form of powder or dustless pellets and shall conform to the require- ments specified in Table 1. 3.2 The mass color and character of the tint and tinting strength formed by a mixture with a white pigment shall be within mutually agreed upon limits of a standard acceptable to both the purchaser and the seller when tested in accordance with Test Method D387. N OTE 1—For the tinting strength test a ratio of 100 parts of white to 1 part of black is usually suitable.
4. Sampling
4.1 Two samples shall be taken at random from different packages from each lot, batch, day’s pack, or other unit of production in a shipment. When no markings distinguishing between units of production appear, samples shall be taken from different packages in the ratio of two samples for each 5000 kg (10 000 lb), except that for shipments of less than 10 000 lb two samples shall be taken. 4.2 At the option of the purchaser, the samples may be tested separately or, after blending the samples from the same production unit in equal quantities, tested as a composite sample.
5. Test Methods
5.1 Tests shall be conducted in accordance with the follow- ingASTM test methods. Test procedures not covered byASTM test methods shall be mutually agreed upon between the purchaser and the seller. 5.1.1 Solvent Extractable Material—Test Method D305. 5.1.2 Color and Tinting Strength—Test Method D387. 5.1.3 Carbon Black—Ash Content—Test Methods D1506. 5.1.4 Heating Loss—Test Methods D1509. 5.1.5 Sieve Residue—Test Method D1514.
