Foreword
This revised standard adopts CEN/T R14823.2003 "Durability of wood and wood products in the timber pentachlorophenol by gas
Chromatography. "
This standard CEN/T R14823.2003 compared to the main changes are as follows.
--- Modify the scope of application (Chapter 1 of this standard, CEN/T R14823.2003 clause 1); increased wood preservative pentachlorophenol
Determination of phenol (this standard 6.2,7.3.1.1);
--- Modify the reference standard (Chapter 2 of this standard, CEN/T R14823.2003 Terms 2);
--- Increased the determination of moisture content of wood.
This standard is proposed and managed by the National Certification and Accreditation Administration Committee.
This standard was drafted. People's Republic of China Guangdong CIQ.
