ISO/ASTM 52903-1:2020 is intended to facilitate communication between material manufacturers, feedstock manufacturers, and purchasers. Required properties of the feedstock and test methods shall be included in the purchase order. Classification of plastic material types, compositions, and testing methodologies can be found in astm and ISO classification documents.
The material manufacturer shall, on request, furnish to the purchaser a certificate of conformance stating that each lot has been sampled, tested, and inspected in accordance with this document and has been found to meet the requirements. This certificate shall include all properties that the purchaser requests, including lot number and other information from original raw materials used, and those ofthe final feedstock (filament) to be used in the manufacture of a part and the standard used in reference for the classification (ASTM D4000 or ISO 1043-1)
