Introduction
GB/T 5754 test method described in this section, is the use of destructive testing to verify performance conveyor belt elongation core rope. by
In this test it is destructive, so this test is only used in the event of litigation or without a certificate issued by the manufacturer with a core.
There is a difference between the unused rope elongation and elongation of the rubber-coated over the rope. To this end, according to the test side
Determination of core values \u200b\u200band with manufacturers certificate values \u200b\u200bshown may vary.
Steel cord conveyor belt longitudinal tensile test
Determination of elongation. Part 1
1 Scope
GB/T 5754 provisions of this part of the determination of steel cord conveyor belt core rope elongation. When measured by rope
Stretching action corresponding to the 10% and 60% of the tensile strength of a predetermined value.
This section applies only to the steel cord conveyor belt.
Note. Determination of tensile strength specified in GB/T 5754.2 in.
2 Normative references
The following documents for the application of this document is essential. For dated references, only the dated version suitable for use herein
Member. For undated references, the latest edition (including any amendments) applies to this document.

tioningperiods)
Principle 3
Taken from the conveyor belt core rope tensile test. Using tensile testing machine or similar when measured by measuring the elongation corresponding to the Rally
Tensile strength specified elongation of 10% and 60% of value. Holder moving speed tensile testing machine shall conform to and kept constant.
4 device
4.1 tensile testing machine shall meet the following requirements.
a) force strength testing machine with the sample can be applied to adapt;
b) the moving speed of the holder can be adjusted to 25mm/min ± 5mm/min and maintained constant;
c) the holder is adjustable to the spacing of not less than 250mm.
4.2 rope fixing means to ensure that the specimen sample should not slide during the test.
You can use two or 50mm diameter of at least 10 times the rope diameter d (see FIG. 1) fixed sheave constituted under the fixture.
4.3 elongation tester accuracy of at least 0.01%.
Rope elongation is generally small, it should be sensitive and accurate meter stretch. Such elongation tester in a sample case was
It may be damaged when pulled off, therefore, the measured force limit set at 60% of the tensile strength of a predetermined value.
Elongation tester can be applied due to the rotation caused by distortion of the nature of the rope is better.
Elongation curve means recording 4.4 with tension changes, if any.
