1.3HPL standard EN 438

The dedicated European EN 438 standard has been in force for HPL since the 1980s. It is now incorporated into the international ISO 4586 standard. The nine parts of EN 438 define all relevant technical properties and test methods for HPL to ensure consistently high quality. HPL and HPL-Compact can only use these designations if they comply with EN 438.
