The Carpet Static Load Tester is a precision instrument designed to simulate the imprints left by furniture on carpets and evaluate the carpet’s recovery after long-term compression. It applies a controlled heavy load over a defined area and period, allowing accurate measurement of thickness reduction and recovery. This tester ensures compliance with international standards for carpet durability testing, providing reliable data for manufacturers, laboratories, and quality control applications.

Application

You can use this tester to evaluate the resilience and durability of textile carpets after static compression. Typical applications include:

(1) Testing the long-term deformation of carpets under furniture loads

(2) Evaluating recovery performance of residential and commercial carpets

(3) Quality control in carpet manufacturing and inspection processes

(4) Research and development of new carpet materials and structures

(5) Comparative testing of carpets with different thicknesses or pile structures

This tester is suitable for all types of textile carpets, including standard carpet tiles and full-size carpet samples.

Standards

The Carpet Static Load Tester is designed to comply with international standards, including:

(1) BS 4939: 1987 (1996) — Determination of the reduction in thickness of carpets after long-term heavy static loading

(2) ISO 3416: 1986 — Wool carpets — Test method 124 Part B

(3) Wools of New Zealand test method 124 Part B — Evaluation of carpet compression and recovery

(4) ASTM D5252 — Standard test method for thickness loss of carpets under static load
