ISO 14930:2012/Amd 1:2021

Overview

ISO 14930:2012/Amd 1:2021 is the latest amendment to the international standard specifying requirements for leather used in dress gloves. Published by the International Organization for Standardization (ISO), this amendment addresses critical performance characteristics such as colour fastness to to-and-fro rubbing, tear load, and colour fastness to light. These properties are essential to ensure leather quality, durability, and aesthetic appeal in high-end dress gloves.

The amendment modifies testing methods and updates performance thresholds to enhance consistency and reliability in leather evaluation. It replaces certain test references and revises requirements to align with industry advancements and consumer expectations.

Key Topics

• Colour Fastness to Rubbing
  The standard defines testing conditions for colour fastness using dry, wet, and artificial perspiration-soaked felt. Different finishing types-including aniline, nubuck, suede, and others-have specific minimum grey-scale ratings to ensure resistance to colour transfer and fading during wear.

• Tear Load Requirement
  Leather’s mechanical strength is measured by tear load using ISO 3377-1, which specifies the single edge tear test. A minimum tear resistance of 15.0 newtons is mandated to ensure durability during use.

• Colour Fastness to Light
  The standard prescribes minimum blue scale ratings for various leather finishing types under ISO 105-B02, ensuring the leather can resist fading when exposed to light sources over time.

• pH and Shrinkage Temperature
  Testing for the pH of aqueous extracts ensures the leather environment does not accelerate degradation. Shrinkage temperature tests confirm thermal stability with a required minimum of 90 °C.

• Elongation at Low Stress
  Leather must exhibit a minimum elongation of 20% at 2 N/mm stress according to ISO 3376, indicating flexibility necessary for dress glove comfort.

Applications

ISO 14930:2012/Amd 1:2021 serves as a vital benchmark for manufacturers, suppliers, and quality assurance professionals within the leather industry-particularly those focused on premium dress gloves. Its applications include:

• Quality Control
  Enabling consistent evaluation of leather materials before selection or shipment to ensure compliance with defined performance criteria.

• Product Development
  Informing material scientists and product designers on the mechanical and aesthetic durability demands specific to dress gloves.

• Regulatory Compliance
  Supporting manufacturers in meeting international standards for leather products, facilitating global trade and customer confidence.

• Consumer Assurance
  Guaranteeing that leather gloves maintain appearance and integrity under normal use conditions such as rubbing, perspiration, and light exposure.
