Sponge foam collapsible hardness tester

This machine is used to measure the indentation hardness of porous elastic materials. The polyurethane foam sample can be tested according to the national standard, and the compressive hardness of sponge, foam and other materials can be accurately measured. In addition, it can also be used to measure the specified compression hardness of the seat foam (such as backrest, seat cushion foam, etc.)， and accurately measure the compression hardness of each foam part of the seat.

Application

Measurement of tensile strength, tear strength, elongation at break, indentation hardness, and compressive stress of polyurethane foam plastics.

Standards

ISO 2439: Flexible cellular polymeric materials — Determination of hardness (indentation technique)

ISO 3386-1: Polymeric materials, cellular flexible — Determination of stress-strain characteristic in compression

ASTM D3574:Standard Test Methods for Flexible Cellular Materials-Slab, Bonded, and Molded Urethane Foams

Features

1. Automatic zero clearing: After receiving the test start instruction, the system automatically clears zero.

2. automatic return: after the sample is broken, it will automatically return to the initial position.

3. change the speed: The machine can change the test speed arbitrarily according to different samples.

4. indicating value verification: the system can achieve the accurate calibration of force value.

5. control method: According to the test needs can choose the test force, test speed, displacement and other test methods.
