ISO/ASTM 52901:2016(E)Standard Guide forAdditive Manufacturing General Principles Requirementsfor Purchased AM Parts1This standard is issued under the fixed designation ISO/ASTM 52901;the number immediately following the designation indicates theyear of original adoption or,in the case of revision,the year of last revision.1.Scope1.1 This document defines and specifies requirements forpurchased parts made by additive manufacturing.1.2 It gives guidelines for the elements to be exchangedbetween the customer and the part provider at the time of theorder,including the customer order information,part definitiondata,feedstock requirements,final part characteristics andproperties,inspection requirements,and part acceptance meth-ods.1.3 It is applicable for use as a basis to obtain parts made byadditive manufacturing that meet minimum acceptance re-quirements.More stringent part requirements can be specifiedthrough the addition of one or more supplementary require-ments at the time of the order.1.4 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.2.Normative references2.1 The following documents are referred to in the text insuch a way that some or all of their content constitutesrequirements of this document.For dated references,only theedition cited applies.For undated references,the latest editionof the referenced document(including any amendments)ap-plies.2.2 ASTM Standards:2D3122 Specification for Solvent Cements for Styrene-Rubber(SR)Plastic Pipe and Fittings2.3 ISO/ASTM Standard:2,3ISO/ASTM 52921 Standard terminology for additive manu-facturing Coordinate systems and test methodologies2.4 ISO Standard:3ISO 17296-3 Additive manufacturing General principles Part 3:Main characteristics and corresponding test meth-ods3.Terms and definitions3.1 Definitions:For the purposes of this document,theterms and definitions given in ISO/ASTM 52900 and thefollowing apply.43.1.1 pre-shipment inspectioninspection carried out by thepart producer on the parts to be supplied according to the partdefinition or on the test units in order to verify that these partsare in compliance with the order requirements.3.1.2 qualification partpart fabricated prior to commenc-ing production which is used to qualify specific aspects of themanufacturing process or part characteristics in order to use asa basis to initiate production.3.1.3 first production partpart with the same geometry(and with the same tolerances),same material and sameproperties as the one requested by the order that allowsverification by the customer that the production processes arecapable of producing parts that meet the requirements.3.1.4 reference partpart with characteristics similar to thedesired final parts but with different geometry or scale orfeatures that can be easily measured or characterized.3.1.4.1 DiscussionReference parts are typically sacrificialparts with simple geometries that are used to verify buildproperties and reduce measurement effort.3.1.5 acceptanceagreement between the customer andpart provider that the delivered part(s)meet the purchase orderrequirements.1This international standard is under the jurisdiction of ASTM Committee F42on Additive Manufacturing Technologies and is the direct responsibility ofSubcommittee F42.05 on Materials and Processes and also is under the jurisdictionof ISO/TC 261.Current edition approved Oct.17,2016.Published March 2017.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.3Available from International Organization for Standardization(ISO),ISOCentral Secretariat,BIBC II,Chemin de Blandonnet 8,CP 401,1214 Vernier,Geneva,Switzerland,http:/www.iso.org.4ISO and IEC maintain terminological databases for use in standardization at thefollowing addresses:IEC Electropedia:available at http:/www.electropedia.org/and ISO Online browsing platform:available at http:/www.iso.org/obp.ISO/ASTM International 2017 All rights reservedThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.1 3.1.6 inspection planSet of instructions specifying theprocess of verification including appropriate resources andsequence of inspections to be referenced by the manufacturingplan.3.1.7 part providermanufacturer or distributor of partsproduced by an additive manufacturing process.3.1.8 customerperson or group ordering and receivingparts manufactured by
