This standard gives the requirements for three additive manufacturing specification levels (AMSL). The AMSLsare numbered in increasing levels of severity from 1 to 3 to reflect increasing technical, quality, and qualificationcriteria.This section describes the conditions that, when met,allow the additive manufacturing process to receivethe appropriate AMSL classification.
When additively manufactured metallic components are ordered to an APl product specification or APl productstandard, the APl product specification or APl product standard shall take precedence over this standard aslong as the requirements of the APl product specification or APl product standard meet or exceed the minimumrequirements set forth in this standard.
