If the referenced standard to which an undated reference is given is replaced, it is recommended that the current version of that standard be used, subject to any changes made to that version. If the referenced standard to which the dated reference is given is replaced, then it is recommended to use the version of that standard with the above year of approval (acceptance). If, after approval of this standard, a change is made to the referenced standard to which the dated reference is made, affecting the provision to which the reference is made, then that provision is recommended to be applied without taking into account that change. If the reference standard is canceled without replacement, then the clause. in which a link to it is given, it is recommended to apply the 8th part, which does not affect this link.

  • Terms and definitions

This standard uses the terms according to GOST R 57558. as well as the following terms with the corresponding definitions:

  • product obtained by the method of additive technological process: A product in the production of which the main (or the only) method of its production is an additive technological process.
  • material supplier: A company that supplies raw powder components for use in an additive manufacturing process.
  • General requirements
    • The nomenclature of characteristics of materials of initial components and materials of products of an additive technological process should fully reflect all the basic properties of materials. The list of required characteristics is determined based on an analysis of the operating conditions of power elements and connections made of a specific material. The list of the main characteristics of the materials of the initial components and materials of the products of the additive technological process and the test standards for their determination are presented in Table 1. If necessary, the presented list can be supplemented with other characteristics or reduced in accordance with the requirements of the customer, taking into account the peculiarities of the operation of the product.
    • The characteristics of the materials of the initial components and materials of the products of the additive technological process must be established in the regulatory documentation, comply with the customer's requirements and are determined by standardized methods on certified, metrologically secure equipment.
    • When choosing tests and determining characteristics of products of an additive technological process, an analysis of the geometric parameters of the product and operating conditions should be carried out.
