EN ISO 6370-1:2021

Overview

EN ISO 6370-1:2021 - "Vitreous and porcelain enamels - Determination of the resistance to abrasion - Part 1: Abrasion testing apparatus (ISO 6370-1:1991)" - is a European adoption of the ISO 1991 text. This standard specifies the requirements for the testing apparatus used to evaluate the abrasion resistance of vitreous and porcelain enamel coatings. The document provides a general description of the apparatus and illustrative figures, and it is intended to ensure consistent, repeatable test equipment across laboratories and production sites.

Key topics and requirements

• Scope: Defines what the part covers - the design and characteristics of the abrasion testing apparatus for enamel coatings.
• Apparatus description: Provides a general description of the device configuration and functional components, supplemented with figures to clarify construction and operation.
• Construction and performance requirements: Sets out the essential requirements that test equipment must meet to perform standardized abrasion assessments reliably (design, mounting, motion mechanism, specimen holding).
• Calibration and reproducibility: Emphasizes the need for consistent apparatus performance and the ability to reproduce test conditions across different instruments and laboratories.
• Safety and compliance: Notes conformity with applicable national implementation rules and cautions about potential patent rights related to apparatus designs (as per the CEN foreword).

(Note: EN ISO 6370-1:2021 adopts ISO 6370-1:1991 without modification.)

Applications

• Quality control: Ensuring consistent abrasion resistance testing in enamel production lines for domestic, industrial, and architectural enamelled products.
• Inspection and certification: Used by test laboratories that verify product conformity to enamel performance specifications.
• R&D and product development: Supporting formulation and process optimization by providing repeatable apparatus standards for comparative testing.
• Procurement and specification: Incorporated into technical specifications and product requirements where abrasion resistance of enamel coatings is a factor.

Who uses this standard

• Coating and enamel manufacturers
• Independent testing and certification laboratories
• Quality assurance and materials engineers
• Equipment manufacturers who design and supply abrasion testers
• Standards bodies and technical committees (e.g., ISO/TC 107 and CEN/TC 262)

Related standards and references

• Other ISO and EN standards covering abrasion test methods, metallic and inorganic coatings, and coating performance are typically used alongside EN ISO 6370-1:2021 to define complete test procedures and acceptance criteria. Users should consult national standards bodies for up-to-date cross-references and implementation guidance.
