Determination of low-temperature brittleness of vulcanized rubber: GB T1682-2014 (single sample method) GB T 15256-2014 (multi-sample method) specifies the low temperature procedure for determining the low temperature of vulcanized rubber without brittle failure when subjected to impact under specified conditions. It is authoritative and practical.

This program is used to determine the mechanical properties of vulcanized rubber or thermoplastic rubber, such as tensile strength, tensile elongation, constant elongation, constant stress elongation, tensile stress at yield point, and elongation at yield point.

It is suitable for testing all paper and cardboard except corrugated paper. There are two measuring methods: constant speed loading method and constant speed stretching method. Main test indicators: tensile strength, tensile index, elongation at break, tensile energy absorption, elastic modulus, etc.

Corrugated paper is a board made of liner paper and corrugated corrugated paper formed by processing corrugated sticks. It is generally divided into single corrugated cardboard, double corrugated cardboard, and triple corrugated cardboard.

The tire mechanical performance testing program developed by Liangong Group can be used to test tires and tire accessories, cords and whole ropes and other products and raw materials to ensure that materials and products meet the high standards of customers.

The electronic universal testing machine professionally developed by Liangong Group is fully applied in the field of wood inspection. This scheme is suitable for the transverse tensile strength test of small wood specimens without defects.
