【国外标准】 Standard Specification for Preformed Sponge Rubber, Cork, and Recycled PVC Expansion Joint Fillers for Concrete Paving and Structural Construction

This specification covers preformed expansion joint fillers for use in concrete, brick, stone, and other paving and structural construction. The fillers are available in the following types: Type I, sponge rubber, which shall consist of preformed strips of a durable elastic sponge rubber compound using synthetic rubber or natural rubber as a base and containing no reclaim rubber or factice; Type II, cork, and Type III, self-expanding cork, which shall both consist of preformed strips that have been formed from clean granulated cork particles securely bound together by a synthetic resin of an incoluble nature; and Type IV, recycled PVC, which shall consist of preformed strips that have been extruded using scrap PVC material and using either no binder or a synthetic resin of an insoluble nature to securely bind it together. Materials shall be sampled suitably according to specified size and number, and shall meet property requirements as to recovery, compression, extrusion, expansion, boiling in hydrochloric acid, and density.1.1 This specification covers preformed expansion joint fillers of the following four types for use in concrete, brick, or stone construction.1.1.1 Type I—Sponge rubber.1.1.2 Type II—Cork.1.1.3 Type III—Self-expanding cork.1.1.4 Type IV—Recycled PVC.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.NOTE 1: Attention is called to Specifications D994/D994M and D1751.1.3 The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
