Friction resistance testing reviews how a product surface changes after repeated contact, rubbing, wiping, or abrasion. It is commonly used for coatings, printed markings, labels, textiles, leather, plastic housings, treated metal surfaces, and decorative layers on consumer products.
Conditions to Define Before Testing
| Item | Review Focus |
|---|---|
| Rubbing medium | Confirm dry cloth, wet cloth, cotton cloth, abrasive paper, eraser, or another specified medium, including its material and condition. |
| Load and cycles | Define load, number of cycles, stroke length, speed, and rubbing mode so results remain comparable. |
| Dry or wet condition | Separate dry rubbing, wet rubbing, solution exposure, or cleaning-agent contact requirements. |
| Sample position | Cover printing, coatings, label edges, frequent-contact areas, and appearance surfaces that matter to the customer. |
| Acceptance criteria | Record wear, color transfer, fading, substrate exposure, residue transfer, marking legibility, and functional change. |
Report Boundary
A friction resistance report should be tied to the tested sample, method, condition, and acceptance criteria. The result should not be extended to all batches, all use environments, or surface performance outside the tested conditions.
Green Ark Recommendation
Green Ark (Shenzhen) Certification Co., Ltd. recommends confirming material, surface treatment, use scenario, and customer acceptance requirements before sample submission. Labels, printed parts, coating samples, and key appearance components should be included in the test plan where relevant.
