GB/T11835 Rock wool,slag wool and its products for thermal insulation Testing Equipment
Product Description:
Product overview: Suitable for rock wool, slag wool, glass wool and products, not for aluminum silicate wool and its products. Under a fixed load, the sample is heated at a certain heating rate to achieve the specified thickness shrinkage rate. The thermal load shrinkage temperature is calculated by interpolation and calculated.
