Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
This standard GB/T 18260-2000 "termite wood preservatives Toxic Effects laboratory test methods" revised basis, instead of the standard
GB/T 18260-2000. This standard compared with GB/T 18260-2000, the major technical changes as follows.
--- Original English title "Laboratorytestmethodforwoodpreservativesofdeterminingtheprotective
effectivenessofpreservativesagainsttermites "read." Methodoflaboratorytestfortoxicity
ofwoodpreservativesagainsttermites ";
--- "1" and based in part on the forestry industry standards LY/T 1283-2011 "toxic wood preservative for laboratory test decay fungi
Test methods "the statement amendments and unity; to add" This standard applies to the evaluation of preservative treated wood against termites performance.
Termites test material modification may also refer to use. ";
--- Add "2 Normative references";
--- Added "3 Terms and Definitions", defines the "preservative toxicity thresholds," "single-sample test," the "double test sample" "nest material"
terms of;
--- Test equipment and materials added to the culture medium described culture medium ingredients added vermiculite and nest material;
--- Selection of tree species for bamboo bamboo added test;
--- Sample Preparation. Sample size of the original standard "50mm × 25mm × 15mm" to "25mm × 25mm × 6mm", bamboo
Material sample size is defined as "25mm × 15mm × 6mm";
--- Number of samples. Number of samples processed per the original standard "3" to "5", and added "termite activity is determined in the control group."
And "medium moisture content in the control group," adds table about the number of samples;
--- Sample flasks are placed in addition to the single sample test placement, adds dual placement test specimen and with maps
Description;
--- Number of termites into flasks. original 3g to 500 termites;
Adjustments --- Test time. from eight weeks to four weeks incubation time;
--- Decay hazard classification adjustments. decay hazard rating of the original standard 0-4 grade 5 to 8 harm standard sample decay 0-10
After good grade standards;
--- Termites harm due to changes in grading standards, adjusted for toxicity thresholds determined criteria;
--- Statistics and forestry industry standards LY/T 1283-2011 "wood preservative for laboratory test methods for bacteria toxicity decadent" unified.
This standard was proposed by the State Forestry Administration.
This standard by the National Standardization Technical Committee timber (SAC/TC41) centralized.
This standard was drafted. Chinese Academy of Forestry Wood Industry Research Institute, Guangdong Academy of Forestry Sciences, Huazhong Agricultural University, River
North Sen Amy Wood Processing Co., Ltd. Deqing three subjects insect repellent, Ltd. Fujian Landscape wooden structure.
The main drafters of this standard. Maxing Xia, Chen Yun Shi, what Xuexiang, should seek Huang, Li Li, Caijian Kun, Chen Jian Ling.
This standard replaces the standards previously issued as follows.
