This standard is subject to revision at any time by the responsible technical committee and must be reviewed every?
Inspection Validating the specifications, value and safety of your raw materials, products and assets. This may be followed by the point of failure notation. Clamp to close the specimen holder. Assurance Testing Inspection Certification.
Certification Formally confirming that your products aatm services meet all trusted external and internal standards. The Gravelometer is designed to evaluate the resistance of d3107 coatings paint, clear coats, metallic plating, etc.
The standards have been prepared so that chips of only one size are shown in each illustration. Other air pressures can be used as agreed upon by the contractual parties.
The second method utilizes a visual comparison of the test panel to the Chipping Rating Standards represented in Fig.
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. In formulating a coating or coating system to meet service requirements, the resistance to chipping damage by? Due to the irregular nature of chipping, the size cannot always be measured exactly so it has to be approximated.
Due to copyright restrictions, we are not able to provide copies of standards. Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. The primary usage of this test is to simulate the effects of the impact of gravel or other debris on automotive parts.
Removal of the tape then pulls off any loose fragments of the coating. Last previous edition D — 74 e1. Since resistance to chipping decreases at lower temperatures partly as the result of decreased? If the vibrator is frozen, discontinue the test until the vibrator has thawed and is operating correctly. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Standards can be obtained from appropriate standards authorities.
Formally confirming that your products and services meet all trusted external and internal standards. NOTE 10—Uniform pressure can be applied by using a pencil eraser or tongue depressor. NOTE 9—Manual mode requires the operator to manually stop the test.
Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility. NOTE 5—For cabinet type gravelometers, keep the lid to the gravel chamber closed during this operation as a safety precaution. Visual Comparison Procedure These standards depict various degrees of chipping severity and are arranged sequentially from best to worst according to chipping frequency.
Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
A point of failure notation may also be included in the rating if a more descriptive statement is asstm. Standard Test Method f NOTE 13—Other rating methods may be employed as agreed upon by contractual parties.
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 xstm since it can vary considerably as other properties are adjusted.
Chip Resistance ASTM D3170
Your comments will receive careful consideration at a meeting of the s3170 technical committee,1 which you may attend. The test sample is mounted in the back of the Gravelometer, and air pressure is used to project 1 s3170 approximately pieces of gravel at ast sample.
Tape is then applied to the entire tested surface. NOTE 6—The gravel hopper must empty in 7 to 10 s. Chipping Ratings consist of one or more letter-number combinations. It is important to remove the small pieces of gravel before reusing the gravel. Send us a request Wilton UK: This test method is designed to produce a controlled amount of impact by the media on the coated panel in order to enhance reproducibility. 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.

For example B6 indicates chips 1 to 3 mm in size. The number-letter combinations are arranged with the most numerous size? Combining values from the two systems may result in non-conformance with the standard. A typical test time is 10 s. There should not be any air bubbles trapped beneath the tape. The second method, while more of an approximation than the? Test panels of by mm 4 by 12 in.
