Sanitary tapware - General specification for electrodeposited coatings of Ni-Cr
The aim of this European Standard is: - to define the condition of the exposed surfaces of tapware, - to establish the characteristics (resistance to corrosion, adherence) of the surface coating, - to describe the tests for verifying these characteristics. It applies to all sanitary fittings (supply or waste fittings) which have a metallic Ni-Cr coating, whatever the nature of the substrate material.
Sanitärarmaturen - Allgemeine Anorderungen für elektrolytische Ni-Cr-Überzüge
Diese Europäische Norm hat zum Ziel: - die Beschaffenheit von sichtbaren Oberflächen von Armaturen zu definieren, - die Anforderungen (Korrosionsbeständigkeit, Haftung) an diese Überzüge festzulegen, - die Prüfungen zu beschreiben, mit denen Beschaffenheit und Anforderungen überprüft werden können. Diese Norm gilt für alle Armaturen (Zulauf, Ablauf), die einen metallischen Ni-Cr-Überzug haben, unabhängig vom Grundwerkstoff.

Overview
EN 248:2002 - Sanitary tapware - General specification for electrodeposited coatings of Ni‑Cr (CEN) specifies requirements for nickel‑chrome (Ni‑Cr) plated finishes on sanitary tapware. The standard defines the condition of exposed surfaces, the performance characteristics (corrosion resistance and coating adherence), and the test methods used to verify those characteristics. It applies to all sanitary fittings (supply or waste fittings) that have a metallic Ni‑Cr coating, irrespective of the substrate material.
Key topics and technical requirements
- Scope and applicability
- Covers exposed surfaces (visible in use). Internal or permanently hidden parts are excluded.
- Surface condition and visual defects
- Lists possible defects (yellowing, stains, pitting/porosity, blisters, wheel marks, cracks, dullness, cuts/scratches, burns, scaliness, orange‑peel, metallic impurities).
- Visual inspection method: naked-eye examination from ~300 mm for ~10 s under diffuse light of 700–1 000 lux.
- Exposed surfaces shall be protected against corrosion and should be free from the listed defects (minor yellow/bluish marks excepted).
- Corrosion resistance (neutral saline spray)
- Type test conducted per ISO 9227 neutral salt spray method.
- Typical procedure: partially dismantled tapware sprayed for a minimum of 200 hours with a rest period halfway through (see EN 248 for exact timing and handling rules).
- Acceptance criteria: the total area of defects (area A) must be ≤ 0.1% of the specimen surface and individual defects ≤ 0.3 mm (visual rating per EN ISO 10289).
- Coating adherence (thermal shock)
- Type test (applies only to Ni‑Cr coatings over plastic substrates).
- Involves a series of air‑based thermal shock cycles (heating to ~70 °C and cooling to ambient - see standard for full cycle parameters and tolerances).
- Example: specified number of cycles and timing; after testing no cracking, blistering or loosening of the coating is permitted.
- Test nature
- Both corrosion and thermal shock procedures are defined as type (laboratory) tests, not routine production quality‑control tests.
Applications and who uses this standard
- Manufacturers of sanitary tapware and chrome‑plated fittings - for product design, qualification and compliance.
- Test laboratories and certification bodies - to perform neutral salt spray and thermal shock assessments.
- Specifiers, architects, procurement teams and building product certifiers - to reference robust Ni‑Cr coating performance criteria in tenders and specifications.
- Quality and R&D teams - to benchmark plating processes and surface finishing quality.
