Overview

EN ISO 12670:2015, titled Thermal spraying - Components with thermally sprayed coatings - Technical supply conditions, is a European adoption of the international standard ISO 12670:2011. Published by CEN, this standard defines the technical supply conditions for parts with thermally sprayed coatings used in manufacturing or repairing components. It supersedes the earlier EN 15311:2007 standard and aligns with quality requirements established in related ISO documents like ISO 14922.

This standard is applicable to industries requiring durable, high-quality thermally sprayed coatings on components for wear, corrosion resistance, and surface improvement. It ensures uniformity in supplier specifications, quality control, inspection, and testing procedures related to thermally sprayed coatings.

Key Topics

Scope and Application

• Specifies technical supply requirements for parts with thermally sprayed coatings.
• Applies when coating quality conforms to comprehensive (ISO 14922-2) or standard requirements (ISO 14922-3).
• Covers both new component manufacturing and component repair processes.

Qualification and Responsibilities

• Manufacturers must maintain a quality management system and ensure personnel qualifications:
  • Spraying coordinators qualified per ISO 12690.
  • Thermal sprayers qualified to ISO 14918 or equivalent expertise.
  • Non-destructive testing personnel certified according to EN 473.
• Spraying equipment must be maintained and qualified per EN 1395 or comparable standards.

Spray Procedure Specification (SPS)

• Manufacturers are responsible for written spray procedure specifications.
• SPS must reference coating and manufacturing instructions including part lists, substrate prep, spraying materials, drawings, and tests.
• Surface preparation, post-treatment (machining, sealing, heat treatment), and changes in process parameters must be documented and controlled.
• Procedure qualification may be conducted following standards like EN 15648 when required.

Materials and Quality Requirements

• Only specified spraying powders or wires (per ISO 14232 and ISO 14919) shall be used.
• Spraying material conformity confirmed by certificates verifying composition.
• Parameters in spray procedures include motion programs, spray technique, and storage conditions.
• Defined acceptance criteria cover coating thickness, hardness, adhesion, porosity, roughness, and possible surface imperfections.
• Standards such as ISO 2063 apply for specific coatings like zinc/aluminium for corrosion protection.

Quality and Testing

• Visual and dimensional inspections are mandatory; 100% visual inspection of coated parts is required.
• Follow ISO 14923 for surface characteristic assessments and ISO 14916 for tensile adhesive strength testing.
• Test specimens accompanying parts should undergo coating using the same procedures.
• Tests such as hardness (ISO 6507-1), bend and cupping tests, and non-destructive testing help ensure compliance.
• Defective coatings must be removed and reapplied following revised and qualified spray procedures.
• Comprehensive documentation of testing, results, and process control must be maintained.

Applications

EN ISO 12670:2015 is critical for industries requiring reliable thermally sprayed coatings to enhance component performance and longevity. Common applications include:

• Aerospace and automotive component repair and manufacturing.
• Heavy machinery surfaces exposed to wear and corrosion.
• Power generation equipment such as turbines for thermal and corrosion protection.
• Oil and gas industry parts requiring durable protective coatings.
• Manufacturing of tools and dies where surface coatings improve function and durability.

By adhering to EN ISO 12670:2015, manufacturers and suppliers ensure the performance consistency of thermally sprayed coatings essential for safety, functionality, and long-term service in demanding environments.

Related Standards

Compliance with EN ISO 12670:2015 involves coordination with several related standards, including:

• ISO 14922-2 & ISO 14922-3: Quality requirements related to thermally sprayed coatings.
• ISO 12690: Defines roles and responsibilities for thermal spray coordination.
• ISO 14918: Specifies approval testing for thermal spraying equipment operators.
• ISO 14232 and ISO 14919: Technical supply conditions for thermal spray powders and wires.
• ISO 14916: Methods for tensile adhesive strength testing of coatings.
• EN 473: Certification for non-destructive testing personnel.
• EN 1395-1: Inspection and testing for thermal spraying equipment.
• ISO 2063: Covers zinc and aluminium coatings for corrosion protection via thermal spraying.

These interconnected standards collectively support the comprehensive control, qualification, and testing framework essential for high-quality thermal spray coatings in industrial applications.

ISO 12670:2011(E)
Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International
Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 12670 was prepared by Technical Committee ISO/TC 107, Metallic and other inorganic coatings.
