Yes, the NG-HDT system conforms to GB/T 8802, a standard that specifies the method for determining the Vicat softening temperature (VST) of plastics. This procedure measures the temperature at which a flat-ended needle penetrates a plastic specimen to a set depth under a defined load, helping evaluate material softening behavior under heat.

The Vicat softening point is an important benchmark for comparing different thermoplastics and for selecting materials suitable for high-temperature environments such as hot water piping, electrical housings, and automotive components.
