Generally, the integrator average will be lower than the average of the five highest peaks. In spite of the empirical nature of the reported values, it is believed they reflect comparative performance of similar touch fasteners tested and measured in the same way.
Now you are ready to begin testing.
You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server. Calculate the average of the values from each f5170 the five samples.
ASTM D – 98 Standard Test Method for Peel Strength (T Method) of Hook and Loop Touch Fasteners
Apparatus Roller—consisting of a smooth steel surface, approximately 43? Last previous edition approved in as D – 98 Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards.
Standards Subsctiption may be the perfect solution. Rated to N lbf Maximum specimen thickness of 6 mm 0.
A number in parentheses indicates the year of last reapproval. Specimen Preparation Hook and loop material for this test shall be in the width as supplied, not to exceed 1 in.
This standard is also available to be included in Standards Subscriptions. We are confident that we have what you are looking for. If the lot does not contain five units, additional rolls shall be selected from the lot to aztm a sample size of five rolls.
The integrator average is relatively easy to calculate given the proper equipment. Give one of our engineers a call today and they can help guide you through the ASTM D test process with the best satm configuration asfm your requirements.
Please first verify aetm email before subscribing to alerts. This standard does not purport to address all of the safety problems, if any, associated with its use. Label each specimen with the type of alignment for later reference.
ASTM D requires vice grips to hold the sample in place. It shall be expressed in linear units of 10 yards m. 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. If material less than 1 in.
The average results from the two laboratories should be compared using Student’s t-test and an acceptable probability level chosen by the two parties before the testing began. Bias—The procedure in Test Method D for measuring the peel strength of hook and loop touch fasteners has no bias because the value of the peel strength of hook and loop touch fasteners can be determined only in terms of a test method.
Select a sample consisting of four contiguous specimens as described in 8. Place the two halves of the hook and loop fastener sheets together and place the steel plate which should be 8 inches long and 1. The weight of the roller including the handle is 11 6 1?
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.
This is a means of determining the resistance to separation when forces are applied normal to the line of separation of the fastener. The values given in parentheses are mathematical conversions to D55170 units that are provided for information only and are not considered standard.
Preparing the Specimens
After 2 s remove the plate. We have no amendments or corrections for this standard. Between-laboratory reproducibility is being determined by the subcommittee. Sampling Select the test samples so as to be as representative of the unit a shipment, a lot, and so forth as possible. As a minimum, the two parties should take a group of test specimens which are as homogenous as possible and which are from a lot of hook and loop of the type in question.
In spite of axtm empirical nature of the reported values, it is believed they reflect comparative performance of similar touch fasteners tested and measured in the same way. As a minimum, the two parties should take a group of test sstm which are as homogenous as possible and which are from a lot of hook and loop of d1570 type in question.
