GB/T11835-2016 Rock Wool, Slag Wool and Its Products for Thermal Insulation Testing Machine

Product Description:

Applicable to rock wool, slag wool, glass wool and products, not to aluminum silicate wool and its products. Under a fixed load, the sample is heated at a certain temperature increase rate to reach a predetermined thickness shrinkage rate. The thermal load shrinkage temperature is obtained by interpolation by calculation.

Features:

Using a single-chip computer, multi-point program heating, heat source using hot plate, safe and reliable, long life, the instrument is equipped with a panel printer to print test results in time.
