AS/NZS 4380:2001 pdf – Motor vehicles-Cargo restraint systems-Transport webbing and components.
2.1.1 Webbing
The webbing shall he produced from high tenacity continuous filament yarn, uniformly woven and free from any significant defects. The edges shall have non-fraying characteristics and should be of the following materials in accordance with AS/NZS 2450:
(a) Polyester (PES.
(b) Polyamide (PA).
(c) Polypropylene (PP).
Polyamide and polyester webbing shall he heat set.
NOTE: Attention is drawn to the differing resistance of man-made fibres to chemicals as summarized in Appendix D.
For composite material where the portion of the added material exceeds 15% of base material, the material shall he identified on the label.
2.1.2 Compments
Steel components shall be manufactured from material that does not exceed 0.45% carbon content and after processing shall comply with minimum breaking strength and deformation requirements.
2.2 DESIGN AND MANUFACTURE
2.2.1 Sewing on webbing
All seams shall be sewn from the same continuous filament as that used to manufacture the webbing. The sewing shall be done by a lock-stitch or similar machine and the stitching shall be evenly embedded into both surfaces of the webbing joint. Lock sewing shall not be visible from either side of the joint.
NOTE: To facilitate inspection, the sewing thread may he of a different colour from that of the webbing
2.2.2 Webbing attachment without sewing
Where a tensioning device is designed for use with webbing in a lashing assembly without sewing. then the information as to strength, width and type of webbing to be used shall be supplied with the device.
2.2.3 Components
2.2.3.1 End fillings
In the design of end fittings. sharp outside edges and corners should be avoided. In particular, those edges which are in Contact with webbing shall he rounded off.
2.2.3.2 Tensioning devices
When a force of 500 N is applied to the handle, a tensioning device shall generate a tensile force in a webbing restraint system of at least 15 per cent of the lashing capacity (LC) or a tensile force of at least 3000 N in a single strap. when a minimum of 2½ turns are applied to the spool. Where removable handles are used, if any component of the applied force can act in the direction of removal of the handle, the handle should he secured against accidental detachment. The maximum possible recoil travel of the end of the handle of the tensioning device shall not exceed 150 mm when released.
3.1 GENERAL
The performance of the webbing restraint system shall be determined in accordance withthe requirements of this Section.
3.2TEXTILE WEBBING
Load restraint webbing which shall not elongate by more than 12% when 50% of the meanbreaking strength is applied and tested in accordance with Appendix A.
3.3 LOAD-BEARING COMPONENTS
All load-bearing components excluding the webbing of the complete load restraint systemshall show no indication of permanent deformation affecting the function at 1.25 times thelashing capacity (LC) and shall afterwards withstand a force of at least twice the lashingcapacity (LC) when tested in accordance with Appendix A.
