Foreword
GB/T 4909 "Test methods for bare wires" is divided into twelve parts.
--- Part 1. General;
--- Part 2. size measurement;
--- Part 3. Tensile test;
--- Part 4. torsion test;
--- Part 5. --- bending test repeated bending;
--- Part 6. bending test --- unidirectional bending;
--- Part 7. winding test;
--- Part 8. --- Brinell hardness test method;
--- Part 9. continuity of coating --- more sodium sulfide;
--- Part 10. Test for continuity of coating --- ammonium persulfate law;
--- Part 11. Coating adhesion test;
--- Part 12. solderability test methods --- balls.
This section GB/T 34909 Part of.
This Part replaces GB/T 4909.3-1985 "Test methods for bare wires tensile test."
Section compared with the GB/T 4909.3-1985 The main changes are as follows.
--- According to GB/T 1.1-2000 requirements, and on the formatting has been modified, and the part of the text has been modified;
--- Added "Normative References" chapter (1985 edition no; Chapter 2 of this edition);
--- Increasing the length of the definition of gauge at break (no 1985 edition; edition 3.1.2);
--- Define refinement elongation as "elongation at break" and "break elongation," (1985, version 2.4; 3.4 edition
And 3.5);
--- Modify the original specimen gauge length (1985 version 4.1.3; this edition 5.1.3);
--- Modified stranded conductors sampling length (1985 Version 4.2.1; 5.2.1 edition);
--- On the front stretch to the distance between the two jaws difference as the elongation of the test method, the fracture location requirements of the supplementary provisions (1985
No version; Excerpts 6.4 Note 2);
--- With 3.4 and 3.5, respectively. "Elongation at break" calculation method is also divided into "elongation at break" and "elongation after fracture," the
Calculation Method (1985 version 6.2; 7.2 edition).

Test methods for bare wires
Part 3. Tensile Test
1 Scope
GB/T 4909 provisions of this part of the test equipment of bare wire tensile testing, sample preparation, measurement procedures, test results and commentary
Set and so on.
This section applies to the measurement of various circular, rectangular, shaped conductors and stranded conductors tensile properties.
Test methods specified in this part is to make sure the length of the specimen subjected to increasing tensile stress, usually until the specimen breaks, measured breaking
Strength and elongation.
This section should be used in conjunction with the GB/T 4909.1-2009.
