Preserved timber

Norma Chilena NCh631:2019 Madera preservada - Extracción de muestras (Chilean Standard (NCh) No. 631:2019: Preserved timber - Sampling)

The notified Standard establishes the sampling method for preserved timber and explains how samples should be taken. It applies to sawn and processed timber, roundwood and veneer that have been pressure-treated with preservatives. The Standard applies to samples taken to check the penetration and retention of preservatives. It does not establish the sampling method for radiata pine, which is set out in Chilean Standard (NCh) No. 819.
