ISO/ASTM 52935:2023(E)
Introduction
For many companies, additive manufacturing (AM) represents an interesting alternative to established
manufacturing processes. The trend towards complex, customised or consolidated components, in
addition to opportunities for reduced lead times and decentralised production allows an economically
feasible use for a growing number of areas. This increasingly applies to many series applications, which
add further demands on the efficiency and consistency of the processes. In particular, components used
in regulated industries (e.g. automotive, rail, aerospace, process and industrial plants, medical) are
subject to high demands in terms of quality and safety.
Where industrial components are produced using additive manufacturing processes, these shall
satisfy the equivalent quality and safety requirements demanded of conventional processes. To this
end, the production chain and environment are designed such that the process quality and resulting
product quality are always consistent and reproducible. To achieve consistency and reproducibility, it
is of utmost importance to ensure that the involved workforce is adequately qualified for all stages of
production.
This document describes the activities and responsibilities of the personnel with coordination roles in
the field of additive manufacturing for metallic parts.

4 Tasks and responsibilities
4.1 General
Coordination personnel can have multiple tasks and responsibilities for additive manufacturing of
metals. These tasks and responsibilities can have varying levels depending on the companies’ needs
and the coordination personnel’s education and experience. Coordination personnel can have tasks and
responsibilities that are at their level of qualification or lower. The company specifies if these tasks,
regardless of the level, are assigned to one single staff or to several staff members.
4.2 Specification of tasks and responsibilities
Each manufacturer is responsible for appointing their AM coordination personnel and specifying their
levels of responsibility for coordination.
The tasks and responsibilities of AM coordination personnel should be selected from Annex B and/
or as specified in applicable standards, contracts, and regulations. The level of competence of AM
coordination personnel should be determined in accordance with the complexity of the AM and related
activities, product type(s), criticality of the application and the quality requirements.
Where more than one person carries out AM coordination, the tasks and responsibilities should be
clearly allocated, such that responsibility is clearly specified, and the persons are competent for each
specific AM coordination task.
The manufacturer shall appoint at least one person to be responsible for AM coordination tasks.
If AM coordination is subcontracted, the tasks and responsibilities shall be specified and documented.
However, compliance with this document remains the responsibility of the manufacturer.
4.3 Tasks and responsibilities
The tasks and responsibilities assigned to AM coordination personnel shall be identified in accordance
with 4.1, 4.2 and Annex B, and documented per Annex A.
Persons other than the AM coordinator may be designated to perform specific tasks on their behalf.
Delegations of this type shall be documented.
4.4 Responsibilities and extent of authorization
The responsibilities and extent of authorization assigned to the AM coordination personnel are
identified as follows:
— their position in the manufacturer’s organization and their responsibilities;
— the extent of authorization assigned to them to carry out the assigned tasks (see Annex B);
— the extent of authorization assigned to them to accept or validate, by signature, technical
administrative documents or contracts, on behalf of the manufacturer, as needed to fulfil the
assigned tasks, for example, for procedure specification and supervision reports.

Introduction
For many companies, additive manufacturing (AM) represents an interesting alternative to established
manufacturing processes. The trend towards complex, customised or consolidated components, in
addition to opportunities for reduced lead times and decentralised production allows an economically
feasible use for a growing number of areas. This increasingly applies to many series applications, which
add further demands on the efficiency and consistency of the processes. In particular, components used
in regulated industries (e.g. automotive, rail, aerospace, process and industrial plants, medical) are
subject to high demands in terms of quality and safety.
Where industrial components are produced using additive manufacturing processes, these shall
satisfy the equivalent quality and safety requirements demanded of conventional processes. To this
end, the production chain and environment are designed such that the process quality and resulting
product quality are always consistent and reproducible. To achieve consistency and reproducibility, it
is of utmost importance to ensure that the involved workforce is adequately qualified for all stages of
production.
This document describes the activities and responsibilities of the personnel with coordination roles in
the field of additive manufacturing for metallic parts.

3.2
examiner
person with knowledge and experience relevant to the qualification, and acceptable to the customer or
examining body or engineering authority
Note 1 to entry: In certain cases, an external independent examining body can be required (ISO/IEC 17024).
4 Tasks and responsibilities
4.1 General
Coordination personnel can have multiple tasks and responsibilities for additive manufacturing of
metals. These tasks and responsibilities can have varying levels depending on the companies’ needs
and the coordination personnel’s education and experience. Coordination personnel can have tasks and
responsibilities that are at their level of qualification or lower. The company specifies if these tasks,
regardless of the level, are assigned to one single staff or to several staff members.
4.2 Specification of tasks and responsibilities
Each manufacturer is responsible for appointing their AM coordination personnel and specifying their
levels of responsibility for coordination.
The tasks and responsibilities of AM coordination personnel should be selected from Annex B and/
or as specified in applicable standards, contracts, and regulations. The level of competence of AM
coordination personnel should be determined in accordance with the complexity of the AM and related
activities, product type(s), criticality of the application and the quality requirements.
Where more than one person carries out AM coordination, the tasks and responsibilities should be
clearly allocated, such that responsibility is clearly specified, and the persons are competent for each
specific AM coordination task.
The manufacturer shall appoint at least one person to be responsible for AM coordination tasks.
If AM coordination is subcontracted, the tasks and responsibilities shall be specified and documented.
However, compliance with this document remains the responsibility of the manufacturer.
4.3 Tasks and responsibilities
The tasks and responsibilities assigned to AM coordination personnel shall be identified in accordance
with 4.1, 4.2 and Annex B, and documented per Annex A.
Persons other than the AM coordinator may be designated to perform specific tasks on their behalf.
Delegations of this type shall be documented.
4.4 Responsibilities and extent of authorization
The responsibilities and extent of authorization assigned to the AM coordination personnel are
identified as follows:
— their position in the manufacturer’s organization and their responsibilities;
— the extent of authorization assigned to them to carry out the assigned tasks (see Annex B);
— the extent of authorization assigned to them to accept or validate, by signature, technical
administrative documents or contracts, on behalf of the manufacturer, as needed to fulfil the
assigned tasks, for example, for procedure specification and supervision reports.
