(Specification)Standard Specification for Insect Screening and Louver Cloth Woven fromVinyl-Coated Glass Yarns
Standard Specification for Insect Screening and Louver Cloth Woven from<brk/>Vinyl-Coated Glass Yarns
ABSTRACT
This specification covers the requirements for insect screening and louver cloth made from vinyl-coated glass yarns. Specifically covered here are: commercial standard vinyl-coated glass yarn insect screening designed and woven primarily for installation in or on any dwelling, patio, screening enclosure, building, or structure for the purpose of keeping out flies, mosquitoes, and most insects; and vinyl-coated glass yarn louver cloth used extensively in soffit and louver vents to keep out most large insects, birds, and airborne litter, while at the same time providing for adequate ventilation and air circulation. Products are produced in two basic classes (Classes 1 and 2) based on nominal thickness. Products shall be suitably tested and conform accordingly to specified requirements in tems of appearance, mesh, roll length, mass per unit area, flame resistance, fabric stability, bursting strength, stiffness index, and color stability to accelerated weathering.
SCOPE
1.1 This specification covers the requirements for vinyl-coated glass yarn insect screening and louver cloth.
1.2 This specification is intended to assist ultimate users by designating the sizes and types of these products that are generally available in the industry.
1.3 This specification shows the terminology and requirements for:
1.3.1 Commercial standard vinyl-coated glass yarn insect screening designed and woven primarily for installation in or on any dwelling, patio, screening enclosure, building, or structure for the purpose of keeping out flies, mosquitoes, and most insects.
1.3.2 Vinyl-coated glass yarn louver cloth used extensively in soffit and louver vents to keep out most large insects, birds, and airborne litter, while at the same time providing for adequate ventilation and air circulation.
1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.
1.5 The following precautionary caveat pertains only to the test methods portions, Sections 8 – 19, 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.
1.6 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.
