A. 4 Test Procedure A. 4.1 Preparation of coating Stir sample to be tested. By product EXPRESS construction ratio (without thinner added) to prepare a mixed sample, stir in Bolivia Suitable coating thickness glass plate or PTFE plate (A.3.12) prepared on. Product under dry conditions specified in the instructions, until the film has completely Drying [since the dry paint if drying temperatures not exceeding (60 ± 2) ℃], remove the film, at room temperature with a crushing device (A.3.2) will be crushed, The coating film is smaller than 5mm. Note 1. The coating film can not be crushed (such as elastic or plastic film), use a clean pair of scissors (A.3.2) the film was cut, the coating is smaller than 5mm. Note 2. The powder samples, sample directly. A. 4.2 Sample Preparation Sample preparation for the second parallel testing. This standard provides the following three sample digestion methods, the laboratory can choose one depending on the conditions. A. 4.2.1 dry ashing method Said pulverized samples taken from about 0.2g ~ 0.3g (accurate to 0.1mg) into a crucible (A.3.7) inside, about 0.5g magnesium carbonate (A.2.3) covering the sample crucible. The crucible was placed on a hot plate inside a fume hood (A.3.3) on gradually raising the temperature of the heating plate (No more than 475 ℃) until the sample is digested to a charred mass and the volatile decomposition products have been fully discharged, leaving only a dry carbonaceous residue. However After the crucible into the (475 ± 25) ℃ in muffle furnace (A.3.4) in the insulation until completely gray. Ashing period shall supply sufficient air oxidation, but the substance is not allowed in the crucible at any stage of combustion occurs. To be filled with the ash of the crucible after cooling to room temperature, 5mL nitric acid (A.2.1), and then the solution in the crucible with a filter (A.3.9), filtered and transferred to a 50mL volumetric flask (A.3.10), and washed with water and filter crucible, and the resulting solution was collected in all the same A volumetric flask and dilute to the mark. At the same reagent blank test. Note. This method does not apply to the fluorocarbon coating. A. 4.2.2 Wet acid digestion He said pulverized samples taken from about 0.1g ~ 0.3g (accurate to 0.1mg) a 50mL beaker (A.3.8), and nitric acid was added 7mL (A.2.1), at the mouth of the beaker stamped a Petri dish on a hot plate (A.3.3) heating the solution was kept on a boil for about 15min, continue to increase Heat until white fumes. The beaker was removed from the hot plate, cool for approximately 5min, was slowly added dropwise 1mL ~ 2mL hydrogen peroxide (A.2.2 The) three Times. Calm and join other reactions required after each addition. The beaker was again placed on a hot plate heated to sample digestion completely. Such kind Incomplete digestion product, remove the coolish, then add the appropriate amount of concentrated nitric acid (A.2.1) and hydrogen peroxide (A.2.2) 1 ~ 2 times, continue heating the sample consumption Complete solution. Residual solution to about 1mL, remove the beaker to cool to room temperature. With approximately 10mL diluted with water, then with membrane (A.3.9) The solution was filtered and transferred to a 50mL volumetric flask (A.3.10) in. Rinse the beaker and the membrane, the resulting solution is all collected in the same Volumetric flask and dilute to the mark. At the same reagent blank test. A. 4.2.3 Microwave Digestion He said pulverized samples taken from about 0.1g ~ 0.2g (accurate to 0.1mg) placed in a microwave digestion vessel were added 5mL nitric acid (A.2.1) and 2mL hydrogen peroxide (A.2.2), and then the digestion tank closed. According to the following procedure digestion temperature. raised in about 10min (180 ± 5) ℃, 30min maintaining the temperature after cooling. After digestion vessel was cooled to room temperature, open the digestion tank, the digestion solution through a membrane filter (A.3.9), filtered and transferred to a 50mL volumetric flask (A.3.10) in. Rinse the inner tank digestion and an inner lid, the washing liquid is collected in the same Volumetric flask, and filters are rinsed with water, the resulting solution was collected in all the same volumetric flask and dilute to the mark. While doing Reagent blank test. When using the above sample digestion method can determine the appropriate digestion conditions based on the actual situation of the sample to ensure that the sample of organic All compounds were removed, and the dissolution of all measured elements. If the sample is treated to have residue, residue use appropriate measurements [such as X Ray fluorescence spectrometry (XRF)] was measured, tested to ensure no element exists. Otherwise it should be changed so that the measured element digestion conditions completely dissolved. Digestion solution was testing should be completed within 24h, otherwise the application of nitric acid (A.2.1) to be stable, so that concentration saved Ba (of HNO3) about 1mol/L. A. 4.3 Test Press A. 4.2 Preparation of test solution using appropriate analytical instruments (A.3.1) Determination of lead content. When using any of the instruments were measured, the analyst should be in accordance with the manufacturer's instructions or the operating manual and its operating Test, and indicate the use of analytical instrumentation in the test report. A. 5 calculation results According to formula (A.1) to calculate the sample Lead content. (Ρ-ρ0) Vp × F (A.1) Where. --- Samples lead content in milligrams per kilogram (mg/kg); ρ --- test solution lead concentration in milligrams per liter (mg/L); ρ0 --- blank solution lead concentration in milligrams per liter (mg/L); Volume Vp --- test solution, in milliliters (mL); F --- the test dilution of the solution; A. 6 precision A. 6.1 Repeatability The same operator to double the relative deviation of the test results should be less than 10%. A. 6.2 Reproducibility Relative deviations between different laboratories test results should be less than 20%.
