Determination of thickness1 ScopeGB/T 4893 provisions of this part of the test method for wood furniture surface film thickness. This section applies to the determination of the thickness of the wooden furniture in the surface of the film. Principle 2 Determination of film thickness based on ultrasonic pulse reflection principle.3 InstrumentUltrasonic coating thickness gauge for measuring film thickness of the wood substrate surface. Accuracy is not less than 1μm, the maximum measured value is not less than 500μm.4 Sample Requirements4.1 Sample size 250mm × 200mm. After finishing the sample shall not be less than 15 ℃ temperature environment placed ventilation after 7d experimenting. May also be in the rear has been completely dried finished furniture directly tested. 4.2 specimen surface should be smooth, no bubble, scratches, faded, wrinkled skin and other defects.5 Test conditions and procedures5.1 Pretreatment Before the test, the sample should be at a temperature of 20 ℃ ± 2 ℃, relative humidity of 60% to 70% for pre-processing 24h. 5.2 Test Point From the edge of the sample within the range of not less than 50mm, and take three pilot sites in different locations or in different directions Determination of film thickness. 5.3 Calibration equipment Accordance with product instructions, first in the known thickness of the film (reference) on the accuracy of the calibration of ultrasonic coating thickness. 5.4 Thickness Measurement After calibration verification equipment in accordance with 5.3 qualified, in order to use ultrasonic thickness gauge. On the film surface to be tested, special coating coupling agent were measured. For smooth, smaller film thickness may be used distilled water The coupling agent. The ultrasonic thickness probe placed on the surface of the film samples were measured, and maintain a constant pressure. Maintained during the measurement probe ...... |
