Overview
EN ISO 19496-2:2017 - Vitreous and porcelain enamels: Terminology - Part 2: Visual representations and descriptions establishes a consistent, practical system for cataloguing detectable defects in sheet steel enamelling. Published by CEN as the European adoption of ISO 19496-2:2017, the document standardizes terminology, visual representations and descriptive guidance so stakeholders use a common language when identifying and reporting enamelling defects. The standard is limited to detectable defects and does not perform defect evaluation or provide acceptance criteria - it supports clear communication and knowledge transfer.
Key topics
The standard is organized to help inspectors and practitioners recognise and describe defects. Core technical topics include:
- Terms and definitions relevant to vitreous and porcelain enamels
- A structured catalogue of enamelling defects, each with:
- Further designations (alternate names)
- Visual descriptions and representations
- Typical origin and causes
- Defect categories covered (examples from the contents):
- Chipping
- Lines - hairlines, bubble lines, watermarks, linear cracks
- Lumps and dimples
- Blisters
- Spots and specks
- Crawling
- Copperheads / burn‑offs
- Fish scales
- Pinholes
- Ripples
- Poor adherence and cracks
- Cross-references to the ISO 19496 series and relevant normative references
Applications / Practical value
EN ISO 19496-2:2017 is designed for practical use where precise defect communication matters:
- Quality control and production inspection - standardizes defect descriptions on enamelled sheet steel to improve consistency between shifts, plants and suppliers
- Supplier and procurement specifications - provides agreed terminology for contracts and inspection reports
- Technical training and visual aids - useful in inspector training, defect atlases and photographic libraries
- Failure analysis and root-cause communication - the origin-and-causes notes help link visual symptoms to potential process issues
- Laboratories and certification bodies - ensures uniform reporting of observable defects during testing or audits
Who should use it
- Enamel manufacturers and applicators (porcelain/vitreous enamel coating producers)
- Steel fabricators and component manufacturers using enamelled sheet
- Quality engineers, inspectors and production supervisors
- Procurement/specification authors and technical writers
- Testing laboratories and conformity assessment bodies
Related standards
- Other parts of the ISO 19496 series (see ISO website for list)
- Standards and guidance developed by ISO/TC 107 and CEN/TC 262 on metallic and inorganic coatings
Keywords: EN ISO 19496-2:2017, vitreous enamel, porcelain enamel, enamelling defects, sheet steel enamelling, terminology, visual representations, defect cataloguing, quality control, inspection.
