SB/T 10558-2009 Preservative wood and wood preservative sampling method
3 Terms and definitions
The following terms and definitions defined in GB/T 14019 and GB/T 27654 apply to this document.
3.1
Chromatedcopperarsenate;CCA
The main component is a mixture of copper, chromium and arsenic salts or their oxides.
[Source. GB/T 14019-2009, 3.3.30]
3.2
Ammonicalcopperquats; ACQ
A mixture of copper salt (calculated as copper oxide) and quaternary ammonium compound (calculated as didecyl dimethyl ammonium chloride).
[Source. GB/T 14019-2009, 3.3.27]
3.3
Effectiveingredients
Active ingredients in wood preservatives that can inhibit the growth of wood decay fungi, molds, discoloration fungi, insects and marine animals in wood.
[Source. GB/T 27654-2011, 3.1]
4 Test principle
This method mainly uses X-ray fluorescence spectrometer to measure the K-layer electronic transition of the copper, chromium, and arsenic element electronic layers. The spectral line intensity is high
Small, and then determine the content of the element to be measured.
