A highly densified wood laminate made by impregnating wood veneers with synthetic resin and compressing them under heat and pressure.

What constitutes a sampling lot?

A lot consists of all compreg boards of the same type, grade, and thickness produced under similar manufacturing conditions in a single batch.

What is the standard conditioning environment before testing?

Specimens are typically conditioned at a temperature of 27 ± 2°C and a relative humidity of 65 ± 5%.

Quick Reference Values

standard testing temperature27 ± 2°C

standard relative humidity65 ± 5%

Key Formulas

Moisture Content (%) = [(W1 - W0) / W0] x 100

Practical Notes

Test specimens must be properly conditioned to equilibrium moisture content before mechanical or electrical testing to ensure consistent and valid results.

Sampling should be strictly random from boards of the same grade, type, and thickness manufactured under similar conditions.

Edges of test specimens must be cut cleanly to prevent micro-cracks from causing premature failure during tensile or flexural testing.
