Introduction to ASTM D714
On painted surfaces, blisters are a frequent problem that can be brought on by chemicals, heat, or moisture. Standardized evaluation procedures are required to evaluate blister size and density reliably across a variety of sample types and situations. Decisions on material selection, maintenance, and repair can be made more easily because of ASTM D714’s use of photographic reference standards, which enable precise paint system comparisons. MaTestLab is one of the best testing service providers, with the best network of testing laboratories in the USA to carry out ASTM D714 tests for our clients. This thorough assessment procedure enhances quality control, long-term durability, paint system performance, and longevity in a variety of applications.
ASTM D714 Test Method
| Exposure of paint film | The paint film is exposed to conditions specified by the seller and the purchaser |
| Evaluation of blistering | The extent of blistering is evaluated by comparing the film to photographic standards |
ASTM D714 Test Specimen
| Specimen Detail | Paint films intended to be used on metal objects are the specimens for ASTM D714. |
| Specimen Size | The intensity of blistering is measured on a scale from 10 to 0. No. 8 shows the tiniest blister that can be seen with the unaided eye, however, No. 10 exhibits absolutely no blistering. The piercing requirements Nos. 6, 4, and 2 show rising blister sizes and offer a consistent framework for assessment. |
ASTM D714 Test Result
In summary, the purpose of this test process is to assess the potential degree of blistering that paint systems may experience in conditions that are known to induce blister development by using photographic reference standards.
ASTM D714 Related Tests
ASTM D714 is related to tests including ASTM D6899 for painted steel and ASTM D5894 for exposure of painted metals to varying conditions.
