JIS Colour Fastness Tester Guide: Applications & Standards

What Is a JIS Colour Fastness Tester?

A JIS Colour Fastness Tester is a laboratory instrument designed to evaluate the resistance of dyed or printed materials to color fading or transfer under specific conditions defined by Japanese Industrial Standards (JIS). It is mainly used to determine how well a material retains its color when exposed to factors such as rubbing, washing, perspiration, water, and light.

The test results help assess the durability and quality of textiles, ensuring compliance with Japanese market requirements.

Applications

JIS colour fastness testing is widely used in:

Textile manufacturing (fabrics, garments, yarns)

Footwear and leather products

Automotive interior materials (seat fabrics, trims)

Home textiles (curtains, upholstery, carpets)

Quality inspection agencies and third-party laboratories

It is particularly important for products exported to Japan or required to meet JIS specifications.

Applicable Standards

JIS colour fastness testers are designed to comply with various JIS standards, including:

JIS L 0849 — Colour fastness to rubbing (crocking)

JIS L 0844 — Colour fastness to washing

JIS L 0848 — Colour fastness to perspiration

JIS L 0846 — Colour fastness to water

JIS L 0842 — Colour fastness to light

These standards specify test conditions, evaluation methods, and grading systems to ensure consistency and comparability.

How to Ensure Accuracy and Repeatability

To obtain reliable test results, the following factors are critical:

Standard-compliant operation: Strict adherence to JIS test procedures

Controlled test parameters: Accurate control of load, speed, temperature, and time

High-quality accessories: Use of standard rubbing cloths, grey scales, and test solutions

Consistent sample preparation: Uniform sample size and conditioning

Regular calibration: Verification of mechanical force, speed, and environmental conditions

Repeatability is ensured by minimizing operator influence and maintaining stable test conditions.

Applicable Material Types

The tester is suitable for evaluating:

Dyed and printed textiles

Knitted and woven fabrics

Leather and synthetic leather

Nonwoven materials

Coated or laminated fabrics

It can be used for both natural and synthetic fibers, including cotton, polyester, nylon, and blends.

Maintenance and Calibration Requirements

Proper maintenance ensures long-term performance:

Clean the testing area and moving parts regularly

Inspect friction heads, clamps, and weights for wear

Calibrate load force and movement speed periodically

Replace consumables such as rubbing cloths and pads

Store the instrument in a stable, dust-free environment

Routine maintenance reduces variability and extends equipment lifespan.

How to Select a JIS Colour Fastness Tester

When selecting a suitable tester, consider:

Standard compatibility: Ensure full compliance with relevant JIS standards

Multi-function capability: Whether one machine can perform multiple fastness tests

Control system: Digital control improves precision and usability

Build quality: Stable structure ensures consistent testing force and motion

Accessories availability: Complete set of standard consumables

Technical support: Availability of calibration and after-sales service

Selecting the right equipment improves testing efficiency and ensures compliance with market requirements.
