ISO 505-2017 pdf free.Conveyor belts — Method for the determination of the tear propagationresistance of textile conveyor belts.
This document specifies a method of test for the measurement of the propagation resistance of an initialtear in textile conveyor belts, either in full thickness or of the carcass only.
This test is intended for application to textile belts in installations where there is a risk of longitudinaltearing.
The following documents are referred to in the text in such a way that some or all of their contentconstitutes requirements of this document. For dated references, only the edition cited applies. Forundated references, the latest edition of the referenced document (including any amendments) applies.
Examination and analysis of the multi-peak tear resistance test traces shall be in accordance withISO 6133.The median peak force is defined as the mean tear resistance.Indicate the resistance of each test piece separately and then indicate the mean value of the resistanceof the two test pieces.
lIf necessary, the width of the test piece (cut-edge) may be adjusted to the gripping width of the jaws bytapering the edges symmetrically on a length at most the same as that of the cut (see Figure 3), with thewidth at the end of the cut part as great as the width of the jaws permits.
The test conditions with regard to temperature and humidity shall be those adopted in Procedure
Mount the two cut ends of the test piece in the jaws of the tensile testing machine either in sense A or insense B(see Figure 4), so that the inner edges of the cut are situated at the centre of each jaw.
The test report shall make reference to this document and shall include the following:
a) identification of the belt tested;
b) the temperature and relative humidity adopted for the conditioning of the test pieces and the tests and the tests
c)the results expressed in accordance with 7.4;
d) whether the test was conducted with or without covers;
e) an account of any test or operating conditions not specified in this document.ISO 505 pdf download.
