ASTM D3953-15(2022)

This specification covers flat steel strapping and seals intended for use in closing, reinforcing, bundling articles for shipment, unitizing, palletizing, and bracing for carloading, truckloading, lifting, and lashing. This specification does not include specialty-type strapping as developed for special applications or strapping produced from alloy metals. Strapping shall be of the following types: Type 1 and Type II; shall be of the following finish: Finish A, Finish B including Grade 1, Grade 2, and Grade 3, Finish C and Finish D; and shall have the prescribed widths and thicknesses in accordance with the specified sizes. Seals shall be of the following classes: Class R and Class H; finishes: Finish A, Finish B including Grade 1, Grade 2, and Grade 3, Finish C, and Finish D; and styles: Style I, Style II, Style III, Style IV, and Style V. Materials shall be cold-rolled carbon steel of the prescribed quality. Strapping and seal shall conform to the physical and mechanical property requirements prescribed for: (1) breaking strength, elongation and seal joint strength, (2) lubrication (by lubricity and edge tests), (3) weld efficiency, (4) seal width, (5) seal application, (6) notch, crimp, and sealless joints, (7) galvanized strapping (by weight loss test), (8) ductility of strapping coating, (9) base metal ductility (by bending test), and (10) straightness (camber, coil set, and spiral twist). The coil configuration are specified and illustrated. Sampling and packaging requirements such as wrapping and packing are also detailed.
