The second method utilizes a visual comparison of the v3170 panel to the Chipping Rating Standards represented in Fig. Combining values from the two systems may result in non-conformance with the standard. It is the responsibility of the user of astj standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
In formulating a coating or coating system to meet service requirements, the resistance to chipping damage by flying objects such as gravel is one of the properties of importance since it can vary considerably as other properties are d310.
Precision and Bias Need help or have a question? NOTE 7—It is important to know that the vibrator may become frozen when the chamber is installed in a cold room or freezer.

A coated 4 inch by 12 inch panel Data: Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm. Atsm primary usage of this test is to simulate the effects of the impact of gravel or other debris on automotive parts. This test method is designed to produce a ast, amount of d3107 by the media on the coated panel in order to enhance reproducibility.
A typical test time is 10 s. The test sample is then removed an gently wiped off with a clean cloth. If gravel remains in the hopper after 10 s, stop the test and investigate the cause. Chipping Ratings consist of one or more letter-number combinations.
Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. 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. It is the judgement of those familiar with this test method that the following precision statements are representative: Place one test specimen at the desired test temperature in the panel holder with the coated side facing the front of the apparatus.
There should not be any air bubbles trapped beneath the tape.
In formulating a coating or coating system to meet 3d170 requirements, the resistance to chipping damage by? NOTE 6—The gravel hopper must empty in 7 to 10 s. 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.
Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. Your comments will receive careful consideration at a meeting of the responsible technical committee,1 which you may attend. This standard has been approved for use by agencies of the Department of Defense. After the gravel impact, tape is applied to remove any loose coating chips and the degree of chipping is determined.
The Gravelometer is designed to evaluate the resistance 3d170 surface coatings paint, clear coats, metallic plating, etc.
A timed test is a test that shuts off the machine after a preset amount of time has passed.

Standards can be obtained from appropriate standards authorities. The American Society for Testing and Materials d31170 no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard. 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 astj.
The second method, while more of an approximation than the? Since resistance to chipping decreases at lower temperatures partly as the result of decreased? It is important to remove the small pieces of gravel before reusing the gravel. Whether your business is local or global, we can ensure your products meet quality, health, environmental, safety, and social accountability standards for virtually any market around the world. NOTE 13—Other rating asstm may be employed as d31700 upon by contractual parties.
The letter designates the chip sizes being counted, and the number designates the number of chips of that size. Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. Standard Test Method f The evaluation may also be carried out using digital optical imaging which offers further possibilities satm evaluation and reproducibility. This test method is similar to SAE J Historical Version s – view previous versions of standard.
Removal of the tape then pulls off any loose fragments of the coating.
Inspection Validating the specifications, value and safety of your raw materials, products and assets. Visual Comparison Procedure For example B6 indicates chips 1 to 3 mm in size. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every?
Note that mesh screen is not a substitute for a space screen. 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 qstm.
