1.1 These test methods cover testing of single filament steel wires that are used to reinforce hose products. By agreement, these test methods may be applied to similar filaments used for reinforcing other rubber products.
1.2 These test methods describe test procedures only and do not establish specifications or tolerances.
1.3 These test methods cover the determinations of the mechanical properties listed below:
| Property | Section | |
| Breaking force (strength) | ||
| Yield strength | ||
| Elongation | ||
| Knot strength | ||
| Torsion resistance | ||
| Reverse bend | ||
| Wrap | ||
| Diameter |
1.4 These test methods are written in SI units; the inch-pound units which are provided are not necessarily exact equivalents of the SI units. Either system of units may be used in these test methods. In the case of referee decisions, the SI units will prevail.
This standard does not purport to address all of the safety concerns, if any, associated with its use. 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.
1.5 This test method covers the measurement of breaking force, yield strength, and elongation of single filament steel reinforcing wire in a tensile test.
1.6 This section describes the test procedure to determine the knot test characteristic of hydraulic hose wire with a diameter less than or equal to 0.82 mm (0.032 in.). In practice, the knot test is most suitable for wires less than 0.50 mm (0.020 in.).
1.7 This test method covers the determination of wire ductility by twisting a wire to failure.
1.8 This test method covers the determination of high stress fatigue performance and ductility by reverse bending wire to failure.
1.9 This test method covers determination of propensity of a wire to develop or propagate, or both, surface cracks from being wound. This test is also known as the wrap-around bend test.
1.10 This test method covers the measurement of the diameter and roundness of single filament wire using a micrometer.
