Overview

EN 16419:2014 is a CEN European Standard that specifies classification and requirements for chamois leather for cleaning purposes. It covers scope, sampling and conditioning, classification by quality (first and second class), essential physical, chemical and mechanical requirements, labelling and marking, and the standard test methods to verify compliance. The standard applies to chamois leather used for drying and polishing smooth surfaces (for example car bodies and windows) and defines both performance limits and how to test them.

Key topics and technical requirements

The standard defines clear quality classes and measurable requirements using referenced EN/ISO test methods:

• Classification

  • First class: suede finished on both sides, even thickness > 0.7 mm, no holes, cuts, hard/cockly places or healed scars.
  • Second class: thickness 0.4–0.7 mm, minor unhealed scars and slight thickness variations allowed; suede finished on one or both sides.

• Chemical limits

  • Tanning metals (Cr): ≤ 200 mg/kg
  • Other heavy metals (total): ≤ 100 mg/kg
  • Matter soluble in dichloromethane: ≤ 15 %
  • Sulphated total ashes: ≤ 8 %
  • Formaldehyde: ≤ 50 mg/kg
  • pH: ≥ 5.5

• Physical / mechanical requirements

  • Tensile strength: ≥ 10 N/mm² (first class) / ≥ 8 N/mm² (second)
  • Elongation at break: ≥ 50 %
  • Tear load (single edge): ≥ 15 N
  • Static water absorption (after 2 min): ≥ 300% (first) / ≥ 200% (second)
  • Shrinkage temperature: ≥ 64 °C

• Sampling, conditioning and test methods

  • Sampling and conditioning per EN ISO 2418 and EN ISO 2419
  • Key test methods include EN ISO 2417 (absorption), EN ISO 3376 (tensile), EN ISO 3377-1 (tear), EN ISO 2589 (thickness), and several chemical test standards.

• Labelling and marking

  • Essential label info: product name (“chamois leather”), surface area (dm²), country of origin, class, and reference to EN 16419. Marking should include a clear product wording and class (example: “Chamois leather for cleaning purposes – EN 16419 - First Class – 8.2 dm² made in Italy”).

Applications and users

EN 16419 is practical for:

• Leather manufacturers and tanneries - to produce chamois leather meeting European quality and safety requirements.
• Quality control and testing laboratories - to perform specified physical and chemical tests.
• Product specifiers, buyers and retailers - to verify class, performance and labelling claims.
• Automotive detailers, glass and optical cleaning product manufacturers - when sourcing high-performance drying/polishing chamois.
• Regulators and procurement teams - to reference a harmonized standard for compliance and public tenders.

Related standards

EN 16419 references multiple EN/ISO standards for test methods and terminology, notably:

• EN ISO 2417, EN ISO 3376, EN ISO 3377-1, EN ISO 2589, EN ISO 2418, EN ISO 2419, EN ISO 4048, EN ISO 4047, EN ISO 17226-1, EN ISO 17072-2, EN ISO 11646.

Use EN 16419 when you need a harmonized European benchmark for chamois leather classification, safety and performance.
