Color. Standards Stock standard. Dissolve 1.245g of potassium chloroplatinate (K2PtCl6) and l.OOOg of cobaltous chloride (C0CI26H2O) in water. Add 100ml of coned HQ, and dilute the soln to 1000.0ml with water. (This soln has a color of 500 on the APHA and ASTM platinum-cobalt scales)... [Pg.161]

Table III gives a survey of the essential characteristics of the alcohols. It is remarkable that, despite the poor color value of the sulfuric acid test, esters can be obtained from the two hexanols with color values falling within the range of the platinum cobalt scale from 35 to 50.

The freezing point measurement, standard method for the detennination of styrene assay until the 1970s, has been largely replaced by gas chromatography. Color is measured spectrophotometrically and registered on the APILA or the platinum-cobalt scale. [Pg.1556]

Objective color measurement is based on tristimulus colorimetry. " This instrumental method measures tristimulus values of light transmitted by a sample and compares the results to the values transmitted by distilled water. The results can be recalculated to the platinum-cobalt scale referred to in the previous standards. The results can also be interpreted by normal methods of color measurement to yellowness index, color, color depth, etc. [Pg.1056]

Platinum-cobalt scale is rrsed for eshmation of color of clear hqtrids. This method gives resrrlts of measrrrements in units equivalent to ASTM method. There are some small differences in the method of color comparison and equipment used. [Pg.76]

There are available specifications of some key plasticizers which can be used as examples for preparation of specification for other plasticizers. Standard specification for octyl o-phthalate includes di-(2-ethylhexyl) phthalate and mixed isooctyl phthalates. Acidity, acid number, ester content, specific gravity, color according to platinum-cobalt scale, and moisture content are specified. Also packaging and package marking are discussed. [Pg.86]

Standard specification for tricresyl phosphate contains requirements for apparent specific gravity, color according to platinum-cobalt scale, potassium permanganate test, unsaponifiable matter, water content, and acidity. ... [Pg.87]
