1.HPL material system
Some HPL composite elements are defined by EN 438-7. HPL composite elements, consist of wood-based substrates (e. g. chipboard, MDF, fibreboard, plywood) with HPL applied on both sides. The properties of such composite elements with HPL surface are defined in the standard EN ISO 13894.
The following standards apply to the components:
| HPL | EN 438 |
| Chipboard | EN 309 / 312 |
| Plywood | EN 313 / 636 |
| Fibreboard (MDF, HDF) | EN 316 / 622 |
| Wood adhesives for non load bearing applications | EN 204 / 205 / 12765 |
