With manual or optional electronic controls, it supports a variety of testing environmentsfrom quality assurance labs to production linesadhering to ASTM D395 for consistent results.


User-friendly and Safe Operation

Designed with operator safety and convenience in mind, the tester includes features such as spring-loaded release, non-slip feet, and calibration gauges. Manual and digital readout options, combined with instant response time, facilitate efficient and reliable measurement routines.

FAQs of Rubber and foam permanent compression tester:


Q: How does the Rubber and Foam Permanent Compression Tester operate?

A: The tester works by compressing rubber or foam specimens between parallel, hardened steel plates under precise, standard conditions, as defined by ASTM D395. You can manually or electrically control the compression, and the displacement is measured either digitally or with a dial gauge.

Q: What types of materials and specimen sizes can be tested on this equipment?

A: This machine is specifically designed for testing rubber, foam, and elastomer samples. The typical specimen size it accommodates is 29 mm x 12.5 mm, and it can simultaneously test up to three specimens thanks to its triple-station design.

Q: When should the equipment be calibrated, and how is it done?

A: Calibration should be performed regularly, typically before each new series of tests or after significant use, to maintain high accuracy (0.01 mm). Use the included calibration gauge and follow the manuals step-by-step calibration instructions.

Q: Where can the tester be installed, and what are its space requirements?

A: This bench-top tester measures 300 x 240 x 400 mm (LxWxH) and weighs approximately 45 kg. Its suitable for installation in laboratories, quality control areas, or production facilities requiring precise compression set analysis.

Q: What is the process for conducting a compression set test at elevated temperatures?

A: For elevated temperature testing, place the tester (or test fixture) inside a standard laboratory oven, set to your desired temperature (up to 200C). The tester is engineered for compatibility with ovens, allowing controlled testing conditions per ASTM standards.

Q: How does multi-specimen testing benefit users?

A: By allowing simultaneous testing of three specimens, the equipment maximizes productivity, ensuring batch consistency and reducing overall testing timemaking it especially valuable for high-throughput labs or manufacturing quality checks.

Q: What safety features are included in this tester?

A: Safety is enhanced through a spring-loaded release mechanism and non-slip feet, preventing accidental releases and movement during operation. These features help protect the user and secure the specimens throughout each test.
