Significance and Use5.1 Pipe and duct insulation systems are often evaluatedwith Test Method E84 to comply with building or mechanicalcode requirements. This practice describes, in detail, specimenpreparation and mounting proce

31、dures for single-componentpipe or duct insulation systems and for multi-component pipeor duct insulation systems.5.2 The material, system, composite, or assembly testedshall be representative of the completed insulation system usedin actual field installations, in terms of the components,including t

32、heir respective thicknesses.5.3 Pipe and duct insulation systems consist of a variety ofmaterials and constructions.5.4 Some testing laboratories have developed a number ofprotocols for testing pipe or duct insulation systems whichutilize one generic type of materials, all of them with aninsulation

33、core and a jacket. Those protocols are the origin ofthis practice, which makes them generic, to reduce materialbias in the standard; they have resulted in the procedurespresented in 6.1. The procedures presented in 6.2-6.5 addressother types of pipe or duct insulation systems.5.5 This practice addre

Specimen preparation and mounting for such sys-tems is described in 6.1 if they are self-supporting and in 6.2 ifthey are not self-supporting.5.5.2 Single component systems, not intended to be bondedto a pipe or duct substrate. Specimen preparation and mounting4This d

36、efinition is similar to the definition of “blanket insulation” in Terminol-ogy C168 from committee C16 on Thermal Insulation.E2231 092for such systems is described in 6.3 if they are self-supportingand in 6.4 if they are not self-supporting.5.5.3 Systems intended to be bonded to a pipe or ductsubstr

Specimen preparation and mounting for such sys-tems is described in 6.5.5.5.4 Reflective insulation materials (see 3.2.10 and 3.2.11)shall be tested using the procedures for specimen preparationand mounting described in Practice E2599.5.5.5 Specimen preparation and mounting procedures forsystem

38、s not described in this practice shall be added as theinformation becomes available.5.6 Supplementary Materials:5.6.1 It is recognized that supplementary materials for pipeor duct insulation systems are normally able to generate heat,flame or smoke. Thus, the fire safety of the entire systemdepends,

39、 at least to some extent, on the fire performance ofsupplementary materials. Consequently, the fire-test-responsecharacteristics of all supplementary materials shall be assessedto obtain a full assessment of the fire-test-response of the pipeor duct insulation system. See Appendix X1.5.6.2 Supplemen

40、tary materials are often present intermit-tently spaced, and not for an extended length, in a pipe or ductinsulation system. Thus, it is not always possible to suitablytest them in conjunction with a pipe or duct insulation system.5.6.3 Testing of Supplementary MaterialsSupplementarymaterials that h

41、ave not been fully tested in conjunction with thepipe or duct insulation system, in accordance with Section 6,shall be tested for flame spread and smoke development assingle-component systems, in accordance with Test MethodE84.5.7 The limitations for this procedure are those associatedwith Test Meth
