General Information

Abstract

This European Standard specifies requirements for the acceptance inspection of thermal spraying equipment in the case of powder feed units used in spray jobs to produce thermally sprayed coatings of reproducible quality.
This part should be used in conjunction with EN 1395-1, which includes general requirements and explanations of procedures.
This part should be used in addition to EN 1395-2 when carrying out acceptance inspection for flame and/or HVOF (high velocity oxygen-fuel) spraying equipment, or EN 1395-4 when carrying out acceptance inspection for plasma spraying equipment.

Overview

EN 1395-7:2007 - Thermal spraying - Acceptance inspection of thermal spraying equipment - Part 7: Powder feed systems - defines minimum requirements and test procedures for acceptance inspection of powder feed units used to produce reproducible thermally sprayed coatings. It is intended to ensure stable, adjustable powder feed rates and uniform powder handling so spray jobs deliver consistent coating quality. This part is to be used together with EN 1395-1 (general requirements) and, where applicable, EN 1395-2 (flame/HVOF) or EN 1395-4 (plasma).

Key topics

  • Scope and applicability
    • Acceptance inspection criteria specifically for powder feed systems in thermal spraying.
    • Applies to standalone carrier-gas feed units and units integrated into flame/HVOF burners.
  • Performance and design requirements
    • Powder feed units must permit uniform processing of the designed spraying powder, allow adjustment of feed rate, and maintain constant, reproducible set values.
    • Carrier gas pressure/flow must be suitable for the spraying process (e.g., chamber low pressure or burner back-pressure).
  • Testing procedures
    • Function test: Verify compliance with manufacturer specification or contract confirmation.
    • Mass flow inspection (cold run): Operate without burner/arc for at least 1 minute, repeat three times. Allowed variation in mass flow: ±5% for Class A equipment and ±10% for Class B. Reproducibility must be shown after a ≥3 hour shutdown and recharge.
    • Powder de‑mixing (PSD) test: Fill container ~1 000 g, feed ~900 g, then analyse remaining ~10% for particle size distribution per EN 1274.
    • Measuring equipment capability: Limits of error specified (max. 5% of set value for certain classes).
  • Documentation
    • Annex A provides an inspection report template (initial test/retest), including fields for carrier gas settings, test results, and acceptance status.

Applications

  • Quality assurance and acceptance testing for:
    • Thermal spray shops and coating service providers
    • OEMs specifying sprayed coatings
    • Equipment manufacturers and suppliers of powder feed systems
    • Contracting parties validating equipment before production use
  • Ensures reproducible coating quality in processes such as flame spraying, HVOF and plasma spraying when used with the relevant EN 1395 parts.

Related standards
