Standard Specification for Strapping, Nonmetallic (and Joining Methods)
ABSTRACT
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.
SCOPE
1.1 This specification covers nonmetallic strapping and joining methods intended for use in closing, reinforcing, and bundling articles for shipment, unitizing, palletizing, and bracing for car loading and truck loading.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.3 The following safety hazards caveat pertains only to the test method portion, Section 12, of this specification: 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.
