Overview
参考- ASTM E139-96 Standard Test Methods for Conducting Creep, Creep-Rupture and Stress-Rupture test of Metallic Materials
Product Details
DESCRIPTION
This product adopts the method of direct load loading on the sample. Generate tensile and bending deformation phenomena in plastic material samples, and use displacement sensors to deform the samples according to the required form for detection. Use a high-temperature chamber to control the temperature of the sample at 20-200 ℃, with a temperature sensor and controller placed in each chamber. The length of the tensile test specimen is 25mm as the standard specimen. The bending test maintains the span distance of the specimen at 50mm.
