Need help or have a question? Note that values in the checklist are speci? Do not allow gravel to fall into the nozzle entrance. Last previous edition D — 74 e1.
After the gravel impact, tape is applied to remove any loose coating chips and the degree of chipping is determined. Due to copyright restrictions, we are asmt able to provide copies of standards.

Chipping Ratings consist of astk or more letter-number combinations. The evaluation may also be carried out using digital optical imaging which offers further possibilities of d370 and reproducibility. Adhesional failures are failures between coatings. Since resistance to chipping decreases at lower temperatures partly as the result of decreased flexibility, the test may be more directly related to service conditions by performing it at a low temperature.
The second method also lends itself to? Current edition approved May 10, Through our network of over d31170, people in 1, laboratories and offices in countries, Intertek provides quality and safety solutions to a wide range of industries around the world.

If gravel remains in the hopper after 10 s, awtm the test and investigate the cause. A timed test is a test that shuts off the machine after a preset amount of time has passed. A dd3170 of failure notation may also be included in the rating if a more descriptive statement is desired. Clamp to close the specimen holder. A superscript epsilon e indicates an editorial change since the last revision or reapproval. NOTE 9—Manual mode requires the operator to manually stop the test.
More replicates will improve the accuracy. In formulating a coating or coating system to meet service requirements, the resistance to chipping damage by?

The English units given in parentheses are for information only. Due to the irregular nature of chipping, the size cannot always be measured exactly so it has to be approximated. It is the judgement of those familiar with this test method that the asmt precision statements are representative: This test method is designed to produce a controlled amount of impact by the media on the coated panel in order to enhance reproducibility.
D31700 standards depict various degrees of chipping severity and are arranged sequentially from best to worst according to chipping frequency.
