A coated 4 inch by 12 inch panel Data: Once started, the test will not stop by itself. There should not be any air bubbles trapped beneath the tape. Tape is then applied to the entire tested surface. Do not allow gravel to fall into the nozzle entrance. Chipping Ratings consist of one or more letter-number combinations. Formally confirming that your products and services meet astj trusted external and internal standards.

After the gravel impact, tape is applied to remove any loose coating chips and the degree of chipping is determined. NOTE 5—For cabinet type gravelometers, keep c3170 lid to the gravel chamber closed during this operation as a safety precaution.

If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below. NOTE 13—Other rating methods may be employed as agreed upon by contractual parties.

Chip Resistance ASTM D3170

Note that values in the checklist are speci? Through our network of over 43, people in 1, laboratories and offices in countries, Intertek provides quality and safety solutions to a wide range of industries around the world.


The primary usage of this test is to simulate the effects of the impact of gravel or other debris on automotive parts. A point of failure notation may also be included in the rating if aztm more descriptive statement is desired.

Standards can be obtained from appropriate standards authorities. Your comments will receive careful consideration at a meeting of the responsible technical committee,1 which you may attend. NOTE 14—Cohesional failures are failures within a coating.

The standards have been prepared so that chips of only one size are shown in each illustration. Other media may be used as agreed by contractual parties.

Clamp to close the specimen holder. The Gravelometer is designed to evaluate the resistance of wstm coatings paint, clear coats, metallic plating, etc.

Due to copyright restrictions, we are not able asm provide copies of standards. NOTE 6—The gravel hopper must empty in 7 to 10 s.

Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. This standard has been approved for use by agencies of the Department of Defense.

Summary of Test Method 3. The American Society for Testing and Materials takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard. This test method is designed to produce a controlled amount of impact by the media on the coated panel in order to enhance reproducibility. Test panels of by mm 4 by 12 in. The evaluation may also be carried out using digital optical imaging which offers further possibilities of evaluation and reproducibility.

It is the responsibility of the user of this standard to establish appropriate safety and asrm practices and determine the applicability of regulatory limitations prior to use. Other air pressures can be used as agreed upon by the contractual parties. The second method also lends itself to? A manual test requires the operator to shut off the machine after d31770 desired amount of time has passed.


Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. These standards depict various degrees of chipping severity and are arranged sequentially from best to worst according to chipping frequency. This test method is similar to SAE J Removal of the tape then pulls off any loose fragments of the coating.

ASTM D / DM – 14 Standard Test Method for Chipping Resistance of Coatings

NOTE 4—Application, metal preparation, and? The test sample is then removed an gently wiped off with a clean cloth. Since resistance to chipping decreases at lower temperatures partly as the result astmm decreased flexibility, the astn may be more directly related to service conditions by performing it at a low temperature. Chip Rating Systems 8. The appearance of the tested sample is then compared to standard transparencies supplied by SAE to determine the chipping ratings.

The test sample is mounted in the back of the Gravelometer, and air pressure is used to project 1 pint approximately pieces of gravel at the sample.
