ISO 23100:2024 PDF

Overview

ISO 23100:2024 - Decorative physical vapor deposition (PVD) coatings on kitchen and sanitary ware fittings - specifies performance requirements and test methods for decorative PVD coatings applied to kitchen and sanitary fittings. Published by ISO (prepared by ISO/TC 107/SC 9), this standard is intended for performance evaluation of decorative PVD finishes on common substrates such as copper alloy, zinc alloy, stainless steel, aluminium alloy and ABS.

Key topics and technical requirements

The standard defines test methods, acceptance criteria and process considerations for decorative PVD coatings. Major technical topics include:

• Coating process and pretreatment

  • Principle of PVD deposition and recommended pre-treatment: alkali degreasing, deionized water rinses and acid activation.
  • Typical vacuum, gas and voltage ranges and note on post‑treatment (e.g., polishing).

• Discoloration resistance

  • Measured by CIELAB ΔE using a spectrophotometer with D65 light source and 10° observation angle.
  • Test: immersion/boiling in distilled water at 60 ± 0.5 °C for 24 h, followed by ΔE calculation.
  • Rating levels (examples): Level 1: ΔE ≤ 0.5, up to Level 4: 2
