James Heal ISO Grey Scale

The ISO Grey Scale sets from James Heal are precision-engineered tools designed to accurately evaluate colour fastness performance in textiles according to international standards. These scales provide consistent, repeatable visual assessments of both colour change (ISO 105-A02) and staining (ISO 105-A03) after standard testing procedures such as washing, rubbing, perspiration, and light exposure.

Crafted in the UK with strict quality control, the scales feature carefully calibrated grey tone steps that reliably indicate the degree of colour loss or staining on adjacent fabrics. Widely used in textile labs, buying offices, and quality control departments, these tools ensure uniform grading and compliance with global testing requirements (ISO & BS EN standards). Durable, accurate, and trusted worldwide, they are essential accessories for colour fastness evaluation in professional laboratories.
