Yes, the NG-HDT is fully compliant with GB/T 1634, a standard that specifies the method for determining the Vicat softening temperature (VST) of plastics. This procedure measures the temperature at which a standard needle penetrates a plastic specimen to a defined depth under a specified load, giving a clear benchmark for material softening under heat.

GB/T 1634 is widely used by plastic manufacturers, quality control laboratories, and research institutes in China to qualify materials for piping, automotive parts, and consumer products. By following this method on the NG-HDT, companies can verify that thermoplastics meet national compliance requirements, compare the softening behavior of different product batches, and support certification processes for both domestic and export markets.
