    Abstract

    This specification describes the manufacturing requirements for spray shield stock and the fabrication and installation requirements for spray shields made from that stock. The physical and mechanical properties for the aluminized glass cloth, thread, and protective outer jacket shall be as specified. If lacing hooks or rings are of the type that fastens by stitching, the hooks or rings shall be attached to the backup washers using a wire stitch machine and wire. The methods for testing the aluminized glass cloth, thread, and protective outer jacket shall be as specified.

    This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

    1. Scope

    1.1 This specification describes the manufacturing requirements for spray shield stock and the fabrication and installation requirements for spray shields made from that stock.

    1.1.1 Sections 2 – 14 address the manufacturing requirements for the spray shield stock. Annex A1 addresses the fabrication and installation requirements for the spray shields.

    1.1.2 Fig. 1 shows the typical construction of a spray shield. Figs. 2-6 show methods of installation of a spray shield on various mechanical joints.

    1.2 The shields are intended for use around mechanical joints (flanged, bolted unions, and so forth) in liquid piping systems to prevent the impingement of flammable liquid on hot surfaces or fluids onto electrical switchboards and components resulting from a leak in the mechanical joint.

    1.3 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
