Escopo e aplicabilidade

This standard applies to production enterprises of preservative-treated wood and its related products. It covers the entire production process, including equipment, preservatives, wood preparation, treatment processes, and quality control. Chapters 11 and 12 regarding environmental protection and labor protection are mandatory, while the remaining sections are recommended. It is essential for manufacturers utilizing vacuum and/or pressure treatment methods.

Requisitos técnicos

The standard specifies comprehensive requirements for the production of preservative-treated wood. It mandates that vacuum pressure equipment must comply with SB/T 10440 and be installed on anti-leakage concrete foundations. Manufacturers must select appropriate preservatives, such as ACQ, CCA, or boron compounds (SBX), and ensure they are properly stored and re-inspected. Wood preparation requires controlling moisture content below 30% when using fixed type water-borne preservatives. The standard outlines various treatment methods, including the full cell, empty cell, and frequency pressure methods. Production enterprises must establish standard operating procedures to ensure product quality and prevent exceeding design pressure limits. Quality control mandates batch testing per cylinder, with specific sampling requirements for retention and penetration. Finished products must be properly labeled according to SB/T 10383 and accompanied by a quality certificate detailing the preservative used and production date.

Métodos de ensaio

Quality inspection follows the guidelines of GB/T 22102. Key testing includes monitoring the preservative absorption amount using the gravimetric method per cylinder. Penetration depth is tested by drilling samples from the top, middle, and bottom of the treated wood and using a colorimetric method to check the depth of preservative infiltration. Sampling for retention must occur immediately after unloading from the treatment cylinder.
