EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of JIS K-5400 testing. JIS K-5400 is a Japanese Industry Standard that specifies test methods for paints. The standard covers a wide range of test methods used to evaluate various properties of paints such as adhesion, gloss, color and durability.
Some of the test methods included in the standard are:
Adhesion test: This test is used to evaluate the adhesion of paint to the surface. The method involves making a cross cut or X-cut on the surface of the painted substrate, applying a pressure sensitive tape over the cut, and then quickly removing the tape to check for any paint removal.
Film thickness measurement: This method is used to determine the thickness of the paint film. It involves using a micrometer or dry film thickness gauge to measure the thickness of the dry film.
Color measurement: This method is used to determine the color of the paint. It involves using a spectrophotometer to measure the reflection or transmittance of light from the painted surface.
Gloss measurement: This method is used to determine the brightness of the paint. It involves using a gloss meter to measure the amount of light reflected from the painted surface at a certain angle.
Endurance test: This test is used to evaluate the resistance of paint to various environmental factors such as sunlight, water and chemicals. It involves subjecting the painted surface to specified environmental conditions and then evaluating the changes in color, gloss, adhesion and other properties of the paint.
These test methods are essential to ensure the quality and performance of paints, as they help identify defects or problems in paint and ensure it meets required standards.
