ASTM F3606-22 - Standard Guide for Additive Manufacturing — Feedstock Materials — Testing Moisture Content in Powder Feedstock

1.1 This standard provides guidelines for measuring moisture in powder feedstock used in additive manufacturing (AM). It applies to metallic, ceramic, and polymer AM powder feedstocks.

1.2 This guide provides a description of test methods commonly used to measure moisture and references to their associated standards.

1.3 This guide provides best practice guidance on how to apply the test methods to make them suitable for AM powder characterization.

1.4 This guide is suitable for measuring moisture in AM powder feedstock over the range of 10 µg/g to 10 000 µg/g.

1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.6 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.
