【国外标准】 Standard Specification for Polyethylene Sheeting for Construction, Industrial, and Agricultural Applications

This specification covers polyethylene sheeting with a determined thickness intended for construction, industrial and agricultural applications. The sheeting shall be made from polyethylene or modified polyethylene, such as an ethylene copolymer consisting of a major portion of ethylene in combination with a minor portion of some other monomer, or a mixture of polyethylene with a lesser amount of other polymers. General requirements for the material are also observed according to their appearance, dimensions in size and tolerance and minimum net weight. The sheeting may be natural, color-tinted, translucent or opaque. The tests given are intended primarily for use as production tests in conjunction with manufacturing processes and inspection methods to insure conformity of sheeting with the requirements of this specification. These tests shall be done in order to determine the following properties: thickness, length and width, weight, impact resistance, tensile properties, reflectance, luminous transmittance, water vapor transmission, and heat sealability.1.1 This specification covers polyethylene sheeting, 250 μm (0.010 in. or 10 mils) or less in thickness, intended for construction, industrial, and agricultural applications.1.2 The values stated in SI units are to be regarded as the standard.1.3 The following precautionary statement pertains only to the test methods portion, Section 8 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.1.4 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.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.
