Chapter 4Measurement results and analysis of the quality of test results. The purpose of this project is to find out what kind of colors by the feasibility study on the production of wood coating derived from natural materials and are equivalent or substitute trigger Exchange color enough to have on the market that are not environmentally friendly. By bringing the trials of wood coating from water, timber measurement and analysis tools through the trial. Experimental study on the selection and tools have been adopted only some of the instruments used to measure the result as follows.4.1 understanding with international standards DIN, ISO, EN and other standards that are used as a tool for testing the quality of industrial wood coating colors.DIN Deutsches Institut fur Normung stands is standard, from the German Institute for Standardization, wood furniture in European countries. Germany has been widely accepted for production and quality standards are DIN standards that are widely accepted throughout Europe, which defines the standard DIN truth is widely used in German only.The European standard EN or Standard from the European countries to accept this standard in many countries through European and sometimes you will see that there is a common standard DIN EN various.ASTM American Society for testing and Materials, is the official standard States.ISO, or International Organization for Standardization is the global quality standards.Japanese Industrial Standard JIS or is Japan country standards.The Swedish standard SIS Instute Standards or country Sweden TIS, or industry standards. Thai country use of TIS or quality testing industry standard and is used as a support or warranty for goods sold in the country as well as DIN used in German, but TIS is not yet accepted by international standards, so TIS is only available in Thailand and neighboring countries, and because trials are familiar with global standards, so using this tool permits from the international standard for testing. Sometimes we also see EN ISO standards as well. In this experimental results testing standard DIN EN ISO as well and, as well, is the standard Cross Cut test standard DIN 53151, which is the German standards use ISO 2409 standard and conforms to ASTM D 3359 is America by today. The same standards of DIN EN 3 this standard called ISO 2409. DIN EN ISO 2409 Cross Cut Test by Cross Cut test according to the standard DIN EN ISO 2409, strength of coating film is told through many levels of adhesion between the film and substrate materials (13) to find the easiest way adhere is the use of a sharp scrape surface film. If the film is brittle or adhesion to the substrate and film, there will be different. In this test, all colors, each 10 times or 10 position on the sheet with the General laekkoe and 10 positions on other pieces 8 pieces painted in LaTeX.DIN 68861 Part 6 tested by heat from a Heat-Resistance (Cigarette Test) according to the standard DIN 68861 Part 6 by using the heat from all the test cigarettes 10 times or 10 position at Imperial General laekkoe and 10 positions on other pieces 8 pieces painted in LaTeX. DIN 68861 Part 1 chemical resistance tests (13) Chemical Resistant DIN 68861 Part 1 standard Test is to find out the capabilities of film coating to prevent water ingress into the. The test is made by dipping water within a specific period of time. When the time is due. A test taken out of the water, and then lining with paper lining. Check the surface of the test plate blister or defects other then left at room temperature for a period of 24 hours, check the test plate surface once again to see the conditions of adhesion to stainless steel. To change the color of the occurrence of fungi and other defects. Use a suitable solvent the sample test from the test plate surface, and then check the abrasives and metal on the part of the test sample.The standard measurement tool 4.2 has been selected and applied analysis. Quality test results are as follows:4.2.1 measurement results and analysis of test results, quality 1 way for adhesion of paint. Compared by abrasion with fingernail color laekkoe color rubber formula and water test by using scratch nails. All the color test 10 times or 10 position on the plate, with 1 piece laekkoe 10 common positions on the other pieces 8 pieces painted in LaTeX. In this test will be able to see the color of the adhesion coatings on preliminary material and easier to test because it does not contain any additional devices in addition to the test's fingernail.4.2.2 measurement results and analysis of results of quality testing how 2 test by placing a Cross Cut according to the standard DIN EN ISO 2409 test Paints and cut Cross Vanished in an experiment and analyze the results from this trial. To see the color of the adhesion coatings on materials, adhesion of the surface will affect the service life. After painting, then it will have a long life, but if bad adhesion refers to the abrasion or product, they will easily out sakit had a shorter work life. The test can be done by using a knife and a standard tape khat Scott DIN EN ISO 2409 standard of strength of coating film is told through many levels of adhesion between the film and substrate materials (13) to find the easiest way adhere is the use of a sharp scrape surface film. If the film is brittle or adhesion to the substrate and film it rehearsing happens all different colors, each 10 times or 10 position on the sheet with the General laekkoe and 10 positions on other pieces 8 pieces painted in LaTeX.
