This specification covers the general and physical requirements for commercial standard solar screening woven from vinyl-coated fiber glass yarn. The material shall conform to general and physical requirements of this specification. General requirements include workmanship, plasticizers, color, selvage, yarn splices, and container dimensions and rolls put-up. Physical requirements include roll appearance, mesh, roll length, roll width, mass per unit area, ignition loss, breaking strength, fabric stability, shading coefficient, flame resistance, blocking resistance, and color stability to accelerated weathering. Testing of both general and physical requirements shall conform to the test methods detailed in this specification. Lot and sample size shall be according to the acceptance number of the specification.

1.1 This specification covers the requirements for vinyl-coated fiber glass solar screening, and should help users recognize the characteristics of acceptable vinyl-coated fiber glass solar screening. This specification is limited in application to vinyl-coated fiber glass solar screening that is produced with a ribbed pattern woven in the warp direction. The applicability of this specification to vinyl-coated fiber glass type solar screening of a non-rib, a double rib (ribs in both warp and filling direction), or a filling rib construction is not known.

1.2 This specification shows the definitions, general requirements, and physical requirements for commercial standard vinyl-coated fiber glass solar screening designed and woven for installation in any dwelling, building, or structure for the purpose of providing a significant reduction in solar heat gain, while providing outward view and interior light. Solar screening provides a structure that has insect-restraining capabilities equivalent to standard insect screening.

Note 1: For information on standard insect screening, see Specification D3656/D3656M.

1.3 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.

1.4 The following precautionary caveat pertains only to the test method portion, Sections 8 – 21 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.

1.5 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.
