ASTM C203 Standard Test for Breaking Load and Flexural Properties of Block Type Thermal Insulation

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of ASTM C203 testing. This standard covers the determination of the breaking load and the calculated bending strength of a rectangular section of a preformed block.

It also applies to cellular plastics. The two test methods are described below:

• Test Method I — A loading system using center loading on a simply supported beam supported at both ends.
• Test Method II — A loading system that uses two symmetrical load points equally spaced from adjacent support points at each end and a distance between the load points of one half the support span.

Both test methods can be used with the following four procedures:

• Procedure A — Mainly designed for materials that break at relatively small deflections.
• Procedure B — Designed specifically for materials subject to large deflections during testing.
• Procedure C — Designed to measure at a constant strain rate using a CRL (constant loading rate) machine. It is used only for breaking load measurements.
• Procedure D — Intended for measurements at constant crosshead speed using a CRT (constant traverse rate) or CRE (constant elongation rate) machine. It is used to break load measurements using a fixed crosshead speed machine.

Comparative tests may be performed according to the method or procedure, provided that the method or procedure is found to be satisfactory for the material being tested.

These test methods are purposefully generic to accommodate widely varying industry practices. It is important for the user to refer to the appropriate material specifications for any special detailed requirements regarding these test methods.

It is the responsibility of the user of this standard to establish appropriate safety, health and environmental practices and to determine the applicability of regulatory restrictions prior to use.
