This standard and ISO 9087.1998 compared to the major technical changes as follows. --- 5.1.1 increase "in the test disc for hardness and Longitudinal shear interception, does not meet the use, adjacent to the site of disc Another saw a long 180mm disk, truncated sample blank, according to the sample size and leave enough shrinkage allowance "(1998 and the present Version 5.1.1). --- 6.2 modify the use of appropriate quality steel hammer to break into the same depth each time, 5 times to 10 times the nail driven into the sample to mark Office, tolerance ± 1mm. In a nail driven into the sample process, the harder the wood, nails driven into easily understood because it is difficult to produce bend The song samples can be pre-drilled diameter of the sample at a corresponding position approximately 1.8mm, the guide hole depth of about 20mm, and then nail driving test Like to sign at the same time, additional recording (1998 edition and 6.2). --- 6.3 modify the sample appears as nail cracking, the test sample should be stopped (in 1998 and this edition 6.3). --- Remove 6.5 "moisture content value and the standard deviation for more than 2% of the sample should be discarded" (1998 edition and 6.5). This standard replaces GB/T 14018-1992 "Standard Test Method for timber grip nail force." The standards are compared with the GB/T 14018-1992 changes as follows. --- 4.3 Modify measurement tools vernier caliper or other measuring tools (1992 edition and 4.3). --- 6.2 modify the use of appropriate quality steel hammer to break into the same depth each time, 5 times to 10 times the nail driven into the sample to mark GB/T 1929-2009 physical and mechanical test materials and test specimens sawing method (ISO 3129. 1975, Wood-Sampling methodsandgeneralrequirementsforphysicalandmechanicaltests, MOD) GB/T 1931-2009 Method for determination of moisture content of wood (ISO 3130. 1975, Wood-Determinationofmoisture contentforphysicalandmechanicaltests, MOD) YB/T 5002 general purpose round pin Principle 3 After a certain length of round steel nails driven into the wood, nail head tester grip, uniform loading speed Stubbs nails, nail holding power measuring timber.4 Test Equipment4.1 test machine, load measurement accuracy should be consistent with GB/T 1928-2009 the provisions of Chapter 6. 4.2 nail holding strength test Annex Figure 1. 1 --- grip nails; 2 --- nails; 3 --- steel frame; 4 --- sample.1 nail holding strength test Annex schematic......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 14018-2009_English be delivered?Answer: Upon your order, we will start to translate GB/T 14018-2009_English as soon as possible, and keep you informed of the progress.
