【国外标准】 Standard Specification for Nonrigid Vinyl Chloride Plastic Film and Sheeting

This specification covers nonrigid, unsupported vinyl chloride plastic film and sheeting in which the resin portion of the composition contains at least 90 % vinyl chloride. The remaining 10 % may include one or more monomers copolymerized with vinyl chloride, or consist of other resins mechanically blended together with poly(vinyl chloride) or copolymers thereof. The film and sheeting covered herein shall be 0.075 to 0.25 mm (3 to 10 mils) in thickness for film and greater than 0.25 mm in thickness for sheet, and shall include the stabilizers and plasticizers necessary to meet the requirements of this specification. The material may be transparent, translucent, or opaque, and may be plain, printed, embossed, or otherwise surface treated. This specification designates three general-purpose types of vinyl chloride film and sheeting - calendered, extruded, and cast. The materials shall be tested for its tensile strength and elongation at rapture, tear resistance, volatile loss, water extraction, low temperature impact, burning rate, shrinkage, and color fastness to rubbing.1.1 This specification covers nonrigid, unsupported vinyl chloride plastic film and sheeting in which the resin portion of the composition contains at least 90 % vinyl chloride. The remaining 10 % can include one or more monomers copolymerized with vinyl chloride, or consist of other resins mechanically blended together with poly(vinyl chloride) or copolymers thereof.1.2 The vinyl chloride plastic film and sheeting covered herein shall be 0.075 to 0.25 mm (3 to 10 mils) in thickness for film and greater than 0.25 mm in thickness for sheeting. The film and sheeting shall include the stabilizers and plasticizers necessary to meet the requirements of this specification. This specification covers transparent, translucent, or opaque film and sheeting that is plain, printed, embossed, or otherwise surface treated.1.3 The values stated in SI units are to be regarded as the standard.1.4 The following safety hazards caveat pertains only to the test methods portion, Section 10, 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.NOTE 1: There is no known ISO equivalent to this standard.1.5 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.
