This specification covers nonmetallic strapping and joining methods for closing, reinforcing, and bundling materials for shipment, unitizing, palletizing, and bracing for car and truck loading. The strappings are classified into five types according to the type of materials used. If necessary, seals and buckles made from steel with zinc, black iron oxide, or any equivalent corrosion protective coatings or plastic buckles may be used. Each sample should be collected and tested using the given procedures and should conform to the required values of breaking strength and elongation, transverse strength, and joint strength, when applicable, for each strapping type.
Before conducting ASTM D3950, it is important to read the entire specification. Standards can be obtained from appropriate standard authorities.
