4 Technical specifications
4.1 General
The supplier and customer shall choose the test methods appropriate to the customer’s requirements.
4.2 Documentation and traceability
To ensure traceability, statements of conformity and inspection documents shall specify the following:
— a unique document reference,
— the name and the address of the supplier,
— the reference of powder lot,
— the product description, including chemical composition, standard and/or trade/common name,
— the nature of powder production process (including e.g. type of gas used, environment conditions),
— the packaging description, including the packaging, the nature of the shielding gas and the desiccant bag, if relevant,
— the date of analysis,
— storage and preservation instructions,
— all of the information to ensure the traceability (e.g. order number, applicable specification).
NOTE 1 When a desiccant bag is in contact with the powder, it can be a source of contamination.
The inspection document shall comply with EN 10204:2005, 4.1.
The statement of conformity should follow TSO/IEC 17050-1.
The reported values shall be linked to the test method used and the corresponding standard. The relevant standards to characterize metallic powder or feedstock for additive manufacturing are detailed in this document. Powder characteristics shall be subjected to a prior customer/supplier agreement.
The product shall be supplied with its material safety data sheet (SDS).
NOTE 2 The inspection document and the statement of conformity can be on the same document.
EXAMPLES Product description: Ni alloy 718 powder 10 *m to 45 ni.
Nature of production process: Vacuum Induction Melting argon gas atomization. Packaging description: 10 kg bottle under Argon protective atmosphere.
For an example of certificate, see Annex B.
4.3 Sampling
Samples shall be representative of the powder lot, ensuring homogeneity when split. Methods and equipment shall follow the requirements in ISO 3954, ASTM B215 or another method subjected to a prior customer/supplier agreement with the method(s) reported.
Procedures should be included for equipment cleanliness prior to sampling to prevent cross contamination of powder.AS ISO/ASTM 52907 pdf download.
