Two new ASTM standards outline procedures for testing pultruded fiber-reinforced polymer (FRP) materials. The soon-to-be-published standards include:

• A test method for measuring the effect of freeze-thaw cycling on a thermoset pultruded composite (D7792)
• A test method for the evaluation of the effects of elevated temperature and moisture conditioning of pultruded fiber reinforced polymer composites (D7992)

Shapes, connections and prefabricated products made from pultruded FRP composites are increasingly incorporated into building and project design and construction. ASTM says the materials have high corrosion resistance and excellent strength-to-weight ratios and can be tailored and reproduced relatively easily to meet specific needs at lower costs.

The standards assist in making comparisons between different materials under elevated temperature and moisture environmental conditions or freeze/thaw conditions. Data obtained from use of the standards will allow structural designers to select materials appropriate for a particular application, based on the new test methods.
