1、Designation: D 4028 07Standard Specification forSolar Screening Woven from Vinyl-Coated Fiber Glass Yarn1This standard is issued under the fixed designation D 4028; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last r

2、evision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers the requirements for vinyl-coated fiber glass solar screening, and should help usersrecognize the

3、 characteristics of acceptable vinyl-coated fiberglass solar screening. This specification is limited in applica-tion to vinyl-coated fiber glass solar screening that is producedwith a ribbed pattern woven in the warp direction. Theapplicability of this specification to vinyl-coated fiber glasstype

4、solar screening of a non-rib, a double rib (ribs in bothwarp and filling direction), or a filling rib construction is notknown.1.2 This specification shows the definitions, general require-ments, and physical requirements for commercial standardvinyl-coated fiber glass solar screening designed and w

5、oven forinstallation in any dwelling, building, or structure for thepurpose of providing a significant reduction in solar heat gain,while providing outward view and interior light. Solar screen-ing provides a structure that has insect-restraining capabilitiesequivalent to standard insect screening.N

6、OTE 1For information on standard insect screening, see Specifica-tion D 3656.1.3 This specification shows the values in both SI units andinch-pound units. “SI” is the technically correct name for thesystem of metric units known as the International System ofUnits. “Inch-pound units” is the technical

7、ly correct name forcustomary units used in the United States. The values stated ineither SI units or in other units shall be regarded separately asstandard. The values expressed in each system may not beexact equivalents; therefore, each system must be used inde-pendently of the other without combin

8、ing in any way.1.4 The following precautionary caveat pertains only to thetest method portion, Sections 8-21 of this specification: Thisstandard does not purport to address all of the safety concerns,if any, associated with its use. It is the responsibility of the userof this standard to establish a

9、ppropriate safety and healthpractices and determine the applicability of regulatory limita-tions prior to use.2.

39、a lot sample for acceptance testing,take the number of rolls of solar screening directed in anapplicable material specification or other agreement betweenthe purchaser and the supplier. Consider rolls of solar screeningto be the primary sampling unit. In the absence of such anagreement, take the num

40、ber of rolls specified in Table 4.NOTE 2An adequate specification or other agreement between thepurchaser and the supplier requires taking into account the variabilitybetween rolls of solar screening and between test specimens from a swatchor roll of solar screening to produce a sampling plan with m

In the absence of suc

42、h an agreement, proceed asfollows:6.3.1 For solar screening appearance, width, mass per unitarea, and length, the rolls in the lot sample serve as thelaboratory sample.6.3.2 For other properties, take at random from the rolls inthe lot sample the number of rolls specified in Table 5. Fromeach roll i

43、n the laboratory sample, take a 2-m (2-yd) full-widthswatch from the end of the roll, but taken no closer than 1 m(1 yd) from the outside end of the roll.6.4 Test SpecimensFor solar screening appearance, width,and length, the rolls in the lot sample serve as test specimens.For other properties, take

44、 test specimens from the swatches inthe laboratory sample as directed in the respective test methodsin this specification.
