Overview
ISO 12690:2010 - Metallic and other inorganic coatings - Thermal spray coordination - Tasks and responsibilities - defines the tasks, responsibilities and competence requirements needed to ensure the quality of thermally sprayed coatings and coated components. The standard covers coordination of thermal spraying activities within a manufacturing department or company, allocation of duties when more than one coordinator is involved, and the requirement that the manufacturer specifies the responsibilities of the spraying coordinator. ISO 12690:2010 supports consistent execution, inspection and documentation of thermal spray work to achieve reliable in-service performance.
Key topics and requirements
- Scope and responsibilities
- Coordination of activities related to thermal spraying, including planning, supervising, executing and inspecting.
- The manufacturer must appoint at least one spraying coordinator and define their responsibilities. Subcontracting is permitted but the manufacturer retains responsibility.
- Tasks and quality activities
- Use of Annex B to allocate essential, thermal-spraying-related tasks (contract/design review, subcontractor control, personnel and equipment checks, procedure qualification, inspection and acceptance).
- Preparation and control of the spray procedure specification, process instructions, and acceptance criteria.
- Job description and authority
- Job descriptions (where required) should list assigned tasks, position, extent of authorization and signing/acceptance powers (e.g., approving procedure specifications or supervision reports).
- Technical knowledge and competence
- Coordination personnel must demonstrate adequate technical knowledge (general and specialized). Annex A references EWF recommendations for practitioner and specialist levels.
- Three competence levels described: comprehensive, specific, and basic technical knowledge depending on production complexity and assigned duties.
- Inspection and testing
- Inspections, non-destructive testing and testing of coatings are integral to coordination; personnel qualifications and testing standards are referenced.
Applications and who uses it
ISO 12690:2010 is intended for:
- Manufacturers and production managers in industries using thermal spraying (aerospace, power generation, oil & gas, automotive, heavy industry).
- Thermal spraying coordinators, QA/QC engineers, production planners and NDT inspectors responsible for spray process control and acceptance.
- Procurement and contract managers who oversee subcontracting and supplier qualification.
- Organizations implementing quality systems for thermally sprayed coatings to ensure compliance with client specifications and national/international regulations.
Practical benefits include clear role definition, improved process control, repeatable coating quality, and reduced risk from improper subcontracting or unqualified personnel.
