GB/T 1933 Wood Density Determination Method3 sample preparation3.1 Sampling method Take a representative sample, the sampling site should avoid thrift, cracking and stress wood, and should be more than 30cm from the end. Hollow Drill sampling, when sampling with a hollow drill, the volume of the sample to be tested should be calculated. 3.2 Determination of density The density of the sample was measured in accordance with GB/T 1933 wood density measurement method, expressed in kilograms per cubic meter (kg/m3). 3.3 Sample preparation method The wood sample is comminuted to pass through a No. 30 standard sieve.4 General safety precautions4.1 Special safety precautions for the use of perchloric acid digestion methods are described in Section 6.3. 4.2 The acid used in this standard produces toxic fumes and should be operated in a fume hood with good venting throughout the operation. Operators should wear protective safety equipment such as protective glasses. 4.3 Do not allow the digestion solution to be dried to prevent explosion. 5 Hydrogen peroxide-nitric acid digestion 5.1 Principle After the sample is decomposed by hydrogen peroxide-nitric acid, the element to be tested becomes soluble and then quantitatively determined. 5.2 Reagents a) concentrated nitric acid (70%, AR); b) Hydrogen peroxide (50%, AR). 5.3 Operation process The wood powder sample is dried in an oven at 125 ° C for about 2.5 h to constant weight, and the analytical balance with a sensitivity of 0.1 mg is accurately weighed out about 5 g. The sample was placed in a 500 mL flask, and 75 mL of concentrated nitric acid was slowly added along the wall of the bottle to completely wet the wood powder (equivalent to a test per gram of wood powder). Add 15 mL of concentrated nitric acid). Add three glass beads and heat slowly on the hot plate; After the initial reaction to form brown smoke, heating is continued until the solution becomes clear and transparent. Cool down, add 5mL peroxygen drop by drop ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of SB/T 10405-2006_English be delivered?Answer: Upon your order, we will start to translate SB/T 10405-2006_English as soon as possible, and keep you informed of the progress.
