Method1. This standard is issued under the fixed designation D ; the number 1 These test methods are under the jurisdiction of ASTM Committee D20 on. Measure the impact resistance of plastic film, coated paper and other materials utilizing the free falling dart method ASTM D ASTM D test for plastic film impact resistance and free falling drop dart cover the determination of the energy that causes plastic film to fail under specified.

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 The values stated in parentheses are for information only.

Standards can be obtained from appropriate standards authorities. Tests on materials that do not break, for any reason, are not considered to be valid. This test uses a single dart configuration and a single drop height, while varying the weight of the dart. Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. The dart is released to drop onto the center of the test specimen.
Formally asttm that your products and services meet all trusted d17009 and internal standards. The test results are shown in the Appendix.
Note 1—Tests on materials that do not break, for any reason, are not considered to be valid. If a test specimen fails, the drop weight is decreased by one unit. Link to Active This link will always route to the current Active version of the standard. Enabling you to identify and mitigate the d170 risk in your operations, supply chains and business processes. Test method A specifies a dart with a 38 mm 1. ASTM D specifies a range of applicability from about 0.
Also, the ISO method does not allow the alternative testing technique described in Section 11 of this test method.
Drop Dart ASTM D, ISO
Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. We are confident that we have what you are looking for. The alternative technique to the ASTM D test method provides for testing specimens in successive groups of ten. 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.
Also, the ISO method does not allow the alternative testing technique described in Section 11 of this test method. Validating the specifications, value and safety of your raw materials, products and assets. Some films exhibit consistency when the initiation energy is the same as the total energy. The method to analyze this test data is called the “Bruceton Staircase” method. A number of test samples are then impacted to determine an appropriate starting point for the weight of the dart.
If a test specimen passes, the drop weight is increased by one unit. It has been noted that certain materials may stretch so far as to bottom out at the base of v1709 test instruments without actually rupturing.
Test results can be used either as a quality control evaluation or for end use comparisons. It has been asttm that certain materials may stretch so far as to bottom out at the base of certain test instruments without actually rupturing.
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.
With sufficient data, correlation between test results and field performance can usually be established. One missile weight is employed for each group and missile weight is varied in uniform increments from group to group.
Link to Active This link will always route to the current Active version of the standard.
Active view current version of standard. By this technique, a uniform missile weight increment is employed during test and the missile weight is decreased astn increased by the uniform increment after test of each specimen, depending upon the result fail or not fail observed for the specimen.
The values obtained by these test variables are highly dependent on the method of film fabrication. Falling dart impact is a traditional method for evaluating the impact strength or toughness of a plastic film. Hence, impact values cannot be normalized c1709 a range of thickness without producing misleading data as to the actual asmt resistance of the material. Film samples that can be cut to mm x mm 9″ x 9″ specimens A minimum of 30 specimens are required for the test Data: Global Reach Intertek is the industry leader with over ashm, people in 1, locations in over countries.
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.

Give our test engineers a call today for help configuring the best test machine and accessories according to your standard.
A series of 20 to 25 impacts are conducted. By this technique, the missile weight employed during the test is decreased or increased by uniform increments after the testing of each specimen, depending upon the result fail or not fail observed for the specimen.
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. Send us a request Need help or have a question? Film has been arbitrarily defined as sheeting having nominal thickness not greater than 0.
The values stated in parentheses are for information only. Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards.
One missile weight is employed for each group and missile weight is varied in uniform increments from group to group. 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. The mounting bracket is adjusted to the appropriate drop height, and the dart is inserted into the bracket. Assurance Testing Inspection Certification.
