Historical Version s – view previous versions of standard. We are confident that we have what you are looking for.

Tests on materials that do not break, for any reason, are not considered to be valid. Test method A specifies a dart with a 38 mm 1. Also, the ISO method does not allow the alternative testing technique described in Section 11 of this test method.

Its range of applicability is from about 0. A study was conducted in which four films made from two resins polypropylene and linear low-density polyethylenewith two film thicknesses for each resin, were impacted using Test Methods D Method AD Procedures A and Band D Have awtm question about conducting the test for this standard?

If a test specimen passes, the drop weight is increased by one unit. The confidence limits of data obtained by this procedure can, therefore, vary significantly, depending on the sample quality, uniformity of film gage, die marks, contaminants, etc. Through our network of over 43, d11709 in 1, laboratories and offices in countries, Intertek provides quality and safety solutions to a wide range of industries around the world.

The mounting bracket is adjusted to the appropriate drop height, and the dart is inserted into the bracket. Inspection Validating the specifications, value and safety of your raw materials, products and assets.

One missile weight is employed for each group and d11709 weight is varied in uniform increments from group to group. Film has been arbitrarily defined as sheeting having nominal thickness not greater than 0. Global Reach Intertek is the industry leader with over 43, people in 1, locations in over countries. The values stated in parentheses are for information only.

The method to analyze this test data is called the “Bruceton Staircase” method. Send us a request Need help or have a question? This test method is technically equivalent to ISO Also, the ISO method does not allow the alternative testing technique described in Section 11 of this test method.

Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. ASTM D specifies s1709 range of applicability from about 0.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Its range of applicability is from about 0. Standards can be obtained from appropriate standards authorities.

This test method may be used for films whose impact resistances asrm masses of about 50 g or less to about 2 kg to fracture them. The values stated in parentheses are for information only. By this technique, a uniform missile weight increment is employed during test and the d1790 weight is decreased or asttm by the uniform increment after test of each specimen, depending upon the result fail or not fail observed for the specimen.

With sufficient data, correlation between test results and field performance can usually be established. Note 2—This test method is technically equivalent to ISO The values obtained by these test variables are highly dependent on the method of film fabrication.

Some films exhibit consistency when the initiation energy is the same as the total energy. 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. Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes.

Differences in results between Test Methods D and D are not unusual since Test Methods D represents failure initiated energy, while Test Method D is initiation plus completion energy. Need help or have a question? It has been noted that certain materials may stretch so far as to bottom out at the base of certain test instruments without actually rupturing.

The test results are shown in the Appendix.

By this technique, the missile weight employed during the test is decreased or d17709 by uniform increments after the testing of each specimen, depending upon the result fail or not fail observed for the specimen. This statement and the test data also appear in the significance sections and appendixes of Test Methods D and D This test method can be used for films whose impact resistances require masses of about 50 g or less to about 6 kg to fracture them.

The method defines the dart size and the drop height for the dart. Assurance Testing Inspection Certification. The alternative technique to the ASTM D test method provides for testing specimens in successive groups of ten.
