To recognize this diversity, a sectional classification system has been esta
8、blished. Door Gasketing Systems is one such sub section and this Standard is a result of the collective efforts of members of the Builders Hardware Manufacturers Association, Inc. who manufacture this product. The total Product Standards effort is, therefore, a collection of sections, each covering
9、a specific category of items. Performance tests have been established to ensure safety and stability to which the public is entitled. There are no restrictions on design. This Standard is not intended to obstruct but rather to encourage the development of improved products, methods and materials. Th
10、e BHMA recognizes that errors will be found, items will become obsolete, and new products, methods and materials will be developed. With this in mind, the Association plans to update, correct and revise these Standards on a regular basis. It shall also be the responsibility of manufacturers to reque
11、st such appropriate revisions. The BHMA numbers which indicate functions of gasketing do not identify size or design and are not intended to be used without necessary supplementary information. Individual manufacturers catalogs are to be consulted. 5TABLE OF CONTENTS 1. SCOPE . 6 2. DEFINITIONS . 6
