Test methods for dipped canvas Part 5. Tensile properties
1 Scope
GB/T 31334 provisions of this part will be made of fiber dipped canvas made into a certain size of the sample, the test of its breaking strength, fracture
Elongation, constant load elongation and other tensile properties of the test method.
This section applies to the manufacture of fiber dipped canvas tensile test. Tensile properties of dipped cord fabric sheets made of fibers
Tests and other dipped scaffold material tensile properties of sheet samples can also be used with reference to the test.

3 test principle
Under the specified test conditions, dipped canvas samples were clamped and fixed on a constant speed (CRE) type tensile testing machine with a constant pull
Stretching speed Applied tensile force to the specimen until the specimen breaks. Read directly from the tensile testing machine or calculated by the tensile strength of the specimen, elongation rupture
Length, constant load elongation and other tensile properties of data.
4 instruments and tools
4.1 Tensile testing machine
This section should be used constant speed (CRE) type tensile testing machine, the test machine should be equipped with automatic recorder or can automatically calculate and display this
Part of the required data processing device, should meet the following requirements.
a) Ability to record breaking strength and elongation values and plot strength-elongation curves;
b) the relative error of the indication of the strength value should not exceed 1%;
c) elongation value indication error should not be greater than 0.1mm;
d) holding the value of gauge length error should not be greater than 1mm;
e) have a suitable measuring range, so that the strength of the specimen rupture in the range of 10% to 90% range.
4.2 Tensile testing machine holder
Clamps used in this part of the test should meet the following requirements.
a) The specimen shall be clamped between the holder planes;
