Overview

EN ISO 16348:2003 - "Metallic and other inorganic coatings - Definitions and conventions concerning appearance" defines appearance-related terminology and sets out the principles for validating appearance when it is specified as a requirement for metallic and other inorganic coatings. Published by CEN in alignment with ISO 16348:2003, the standard helps ensure consistent visual assessment and agreement between suppliers, manufacturers and purchasers.

Key topics and requirements

• Definitions: Clear, standardized terms such as appearance, uniformity of appearance, blemish and visible defect to avoid ambiguity in specifications and inspection.
• Principle: When appearance is a contractual requirement, a validation test is mandatory - particularly for use as a referee method. A description alone is insufficient.
• Comparator / reference approach:
  • Use of representative approved reference samples to define acceptable appearance and allowable variation.
  • Reference samples should be produced with the same fabrication and coating processes as the finished parts to ensure reproducibility.
  • All interested parties must agree on reference samples; samples should be retained for future reference and inspection.
  • Note: special storage or expiry considerations may apply to preserve sample durability.
• Measurement techniques: Instrumental methods (e.g., glossmeters, surface profiling, colour matching) may be used where the product standard or purchase order specifies required properties.
• Inspection conditions: Lighting, viewing angle, magnification and distance must be agreed at enquiry/order time to ensure consistent inspection.
• Test report requirements: At minimum the report shall include:
  • type of test/specification number
  • test and examination conditions
  • details of the article tested
  • any deviations from the product standard

Applications and who uses this standard

EN ISO 16348:2003 is practical for:

• Coating suppliers and applicators defining acceptance criteria for metallic coatings
• Manufacturers and OEMs specifying visual quality requirements in purchase orders
• Quality managers and inspection labs performing appearance validation and referee testing
• Procurement and contract engineers seeking clear contractual definitions for appearance
• Test houses and certification bodies needing standardized reporting and inspection conditions

Typical uses: acceptance testing, quality control, dispute resolution (referee comparisons), and development of product standards specifying appearance.

Related standards

• EN ISO 2064:1996 - measurement of coating thickness
• ISO 2079 - general classification of surface treatment terms
• ISO 2080 - electroplating vocabulary
• ISO 10289 - corrosion test rating of coatings
• EN 12508 - vocabulary for corrosion protection and coatings

Keywords: EN ISO 16348:2003, metallic coatings, appearance validation, reference samples, coating uniformity, inspection conditions, comparator method.
