ASTM D4642-25

1.1 This test method covers the determination of platinum in nonzeolitic, fresh reforming catalysts containing platinum as the only precious metal, in the range of concentration of 0.200 to 0.700 weight %.

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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

4.1 This test method provides a means of determining the platinum content of fresh reforming catalysts where the platinum is supported on an all alumina substrate.5

4.2 This test method is not intended to cover samples containing metals other than platinum. Palladium, rhenium, and rhodium in particular interfere with the spectrophotometric determination of platinum.
