ISO 75-1, Plastics — Determination of temperature of deflection under load — Part 1: General test method, is the test method for flexural properties.
ISO 75-1 Plastics — Determination of temperature of deflection under load — Part 1: General test method
At a Glance
Document type: Test Method.
Edition: active, current edition ISO 75-1:2020.
Property determined: flexural properties.
Values reported: that is flexural stress under three-point loading, of plastics.
Scope
General test method for the determination of the temperature of deflection under load, that is flexural stress under three-point loading, of plastics.
Different types of test specimen and different constant loads are defined to suit different types of material.
Suitable for assessing the relative behaviour of different types of material at elevated temperature under load at a specified rate of temperature increase.
What the Result Tells You
A test to ISO 75-1 returns that is flexural stress under three-point loading and of plastics. Each value is reported against the specimen geometry and the conditions the method fixes, which is what makes results from two laboratories directly comparable.
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
ISO 75-1: the designation as published by the issuing body.
Year suffix: the revision is identified by its year, as in ISO 75-1-20. 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.

Part of a Series
ISO 75-1 is one part of ISO 75. The other parts of the series cover related requirements, so the part cited in your specification is the one that governs the test.
