When no markings distinguishingbetween units of production appear, samples shall be takenfrom different packages in the ratio of two samples for each4545 kg or (10 000 lb), except that for shipments of less than1000 lb, two samples shall be taken. At the option of thepurchaser,
10、each sample may be tested or samples from thesame production may be blended in equal quantities to form acomposite sample.5.

17、2 to 50 mg/L) in H2SO4(sp gr 1.84).The absorption maxima are so sharp and well defined that they may beused for positive qualitative identification of the various phthalocyaninepigments. Phthalocyanine green has maxima at approximately 820 and860 nm for bromine-free types; for the chlorinated-bromin
18、ated types, themaxima appear at approximately 830 to 840 nm, and 875 to 885 nm.5.6 Basic Dye DerivativesTest Method D1135.5.7 Other Organic Coloring MatterTest Method D1135.5.8 Chrome Green and Iron BlueTest Method D1135.6.
