ASTM D523 Standard Test Method for Specular Gloss

ASTM D523 is a standard test method used to determine the specular gloss of plastic films, coatings, and related products. The test involves shining a beam of light at a specific angle onto the surface and measuring the amount of light that is reflected back.

GET STARTED

Introduction to ASTM D523 

ASTM D523 is a standard test method that measures the specular gloss of plastic films, coatings, and related products. Gloss is an important aesthetic property of materials, and it plays a significant role in determining the perceived quality of the product. Specular gloss refers to the amount of light reflected off a surface at a specific angle under a defined light source. The results obtained through this method are especially used for quality control, reliability check, performance evaluation, and specification purposes.

ASTM D523 Test Method

The test method ASTM D523  involves placing a sample of the plastic film or coating on a gloss meter and shining a beam of light at a specific angle onto the surface. The amount of light reflected back is then measured and used to calculate the specular gloss of the sample. The test is typically performed in two steps, as outlined in the table below:

Preparing the SampleIt involves preparing the sample for testing. The sample is typically a thin film or coating that is cut into a specific size and shape to fit into the gloss meter. The sample is cleaned and dried to remove any dirt or debris that may affect the test results.
Specular Gloss TestIt involves measuring the specular gloss of the sample. The sample is placed on the gloss meter, and a beam of light is directed at the surface at a specific angle. The angle of the light source and the angle of the detector are both specified in the standard. The amount of light reflected back is then measured and used to calculate the specular gloss of the sample.

ASTM D523 Specimens

Specimen detailsThe specimen used in the ASTM D523 test method is a plastic film or coating. The sample is typically in the form of a thin sheet or film and is prepared by cutting it into the desired size and shape.
Specimen dimensionsThe acceptable specimen size for ASTM D523 varies depending on the type of gloss meter used. The sample size is typically between 10 and 50 mm in diameter or length.
Specimen preparationThe sample is prepared by cutting the plastic film or coating into the desired size and shape. The sample is then cleaned and dried to remove any dirt or debris that may affect the test results.

ASTM D523 Results

The results of the ASTM D523 test method are reported as the specular gloss of the plastic film or coating sample. The specular gloss is calculated as the ratio of the amount of light reflected at a specific angle to the amount of light reflected from a reference material under the same conditions. The results are used to evaluate the quality of the plastic film or coating and to ensure that it meets the necessary specifications for its intended use.

Tests related to ASTM D523
ASTM D523 is related to several other ASTM standards that measure the properties of plastics and coatings. These standards include ASTM D1003 for haze and luminous transmittance of plastics and ASTM D2244 for calculation of color differences from instrumentally measured color coordinates. These tests are commonly used in conjunction with the ASTM D523 test method to fully evaluate the properties of plastic films and coatings.
