Full title and description

STB BS ISO 17228-2005 — Leather. Tests for colour fastness. Change in colour with accelerated ageing. This document is the British adoption (BS ISO 17228:2005) of the ISO 17228:2005 test method giving procedures to simulate and assess colour changes in leather caused by accelerated ageing.

Abstract

The standard specifies a set of accelerated ageing procedures and assessment principles intended to indicate the changes in surface colour and bulk colour that leather may undergo when exposed to environmental stresses over time. Test conditions are selected according to leather type and intended end use; methods provide specimens ageing for subsequent colour-change evaluation and for preparing samples for related dimensional-change tests.

Scope

Specifies ageing procedures to obtain an indication of colour changes that leather may experience under prolonged exposure to specific environments. The standard describes selection of test conditions appropriate to different leather types and intended uses, and provides procedures for preparing and ageing specimens to assess change in colour and to provide aged samples for related tests (for example dimensional-change testing).

Key topics and requirements

• Definitions and principles for accelerated ageing of leather specimens.
• Prescribed ageing procedures and environmental conditions (temperature, humidity, light/UV exposure and other relevant stressors) tailored to leather type and end use.
• Specimen preparation and conditioning prior to ageing.
• Assessment of change in colour after ageing — visual appraisal and instrumental comparison; use of standard grey scales and relevant colourfastness assessment practices.
• Requirements for reporting results, including test conditions, specimen details and observed colour change.
• Cross-reference to related test methods (for example ISO colourfastness guidance and dimensional-change tests).

Typical use and users

Used by tanneries, leather manufacturers, quality-control and testing laboratories, product specifiers and R&D teams assessing leather colour stability. Commonly applied when specifying leather for furniture, footwear, automotive interiors and other applications where long-term appearance retention is required.

FAQ

Q: What is this standard?

A: It is the 2005 international test method (adopted as BS ISO 17228:2005) that specifies accelerated ageing procedures and assessment principles for determining change in colour of leather.

Q: What does it cover?

A: It covers specimen preparation, selection of ageing conditions appropriate to leather type and use, procedures for ageing specimens, and methods for assessing and reporting change in colour after accelerated ageing.

Q: Who typically uses it?

A: Tanneries, leather goods manufacturers, independent testing laboratories, automotive and furniture specification teams, and researchers concerned with leather appearance durability and quality control.

Q: Is it current or superseded?

A: ISO 17228:2005 has been superseded — it was revised and replaced by ISO 17228:2015 (published in 2015). National adoptions of the 2005 edition (including BS and EN versions) were withdrawn in 2015 when the revised edition was published.

Q: Is it part of a series?

A: It is part of the family of leather testing standards and is commonly used alongside ISO colourfastness guidance (ISO 105 series), ISO 17130 (dimensional change) and IULTCS/IUF leather testing methods.

Q: What are the key keywords?

A: Leather, colour fastness, accelerated ageing, colour change, test method, IULTCS, BS ISO 17228.
