Significance and Use
4.1 This test method provides a means of determining the palladium content in fresh catalysts containing molecular sieves.
4.2 This test method is not intended to cover samples containing metals other than palladium.
1.1 This test method covers the determination of palladium in molecular sieve-containing fresh catalysts with about 0.5 weight % of palladium.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 This standard does not purport to address all of the safety concerns, 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.
