1.1 This test method covers determining the activity and selectivity of either equilibrium or laboratory deactivated fluid catalytic cracking (FCC) catalysts. The activity is evaluated on the basis of weight percent conversion of gas oil in a microactivity unit. The selectivities are evaluated on the basis of weight percent yields of specifically defined products resulting from the catalytic cracking of gas oil. 1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses are provided for information only. 1.3 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

1.1 This test method covers the titrimetric determination of zirconium in zirconium driers used in the coatings industry and utilizes the disodium salt of ethylenediaminetetraacetic acid dihydrate (EDTA). 1.2 This test method is limited to the determination of the zirconium content of a liquid zirconium drier that does not contain other drier elements. The test method is not applicable to drier blends and does not differentiate hafnium from zirconium. 1.3 All cations that can be titrated with EDTA in acid media interfere and must not be present in the sample. 1.4 This test method has been tested for concentrations of 6 and 12% zirconium, but there is no reason to believe that it is not suitable for higher or lower zirconium concentrations provided specimen size is adjusted proportionately. 1.5 This standard does not purport to address the safety problems associated with its use.
