GB/T 1634.1 Plastics — Determination of temperature of deflection under load — Part 1: General test method
At a Glance
Document type: Test Method.
Edition: edition GB/T 1634.1-2019.
Property determined: deflection temperature under load.
Scope
Chinese national general test method for the temperature of deflection under load of plastics.
Corresponds to the ISO 75-1 approach.
What the Result Tells You
A test to GB/T 1634.1 characterises the deflection temperature under load of the material or assembly under the conditions the method fixes: specimen form, rate of loading and the environment in which the test is run.
Because the numbers depend on those fixed conditions, a result is only meaningful when the report names the standard, the edition and any options the method allows.

Reading the Designation
GB/T 1634.1: the designation as published by the issuing body.
Year suffix: the revision is identified by its year, as in GB-19. A specification that names an edition fixes that edition; a later revision does not apply to an order retroactively.
When a drawing, purchase order or quality procedure cites this document, the test setup, the specimen and the report follow that citation.
