IEC 60811-1-4 Clause 8.3 and 8.4 Low Temperature Tensile Testing Machine

The LS-B40 Low Temperature Tensile Testing Machine is a precision-engineered apparatus specifically designed for evaluating the low-temperature tensile properties of cable insulation and sheathing materials in accordance with international standards. This equipment requires integration with a compatible low-temperature 32 to establish the requisite testing conditions.

Prepared specimens, typically Type I and II dumbbell configurations, are securely mounted using non-self-tightening clamps. The system applies controlled tensile force at a precisely regulated speed of 25±5mm/min. Critical mechanical parameters, including specimen elongation under low-temperature conditions, are measured with digital displacement display accuracy of ±1mm. This data enables quantitative assessment of the tensile resistance and material integrity of cable insulation and sheathing when subjected to low-temperature environments, ensuring compliance with relevant technical specifications and quality requirements.
