Summary of Practice4.1 This practice describes procedures for specimen preparation and mounting when testing pipe and duct insulation materialsto assess flame spread and smoke development as surface burning characteristics using Test Method E84.4.2 Pipe or duct insulation systems (
31、or composites related to pipe or duct insulation) consist of an insulation core, with orwithout a jacket, and with or without an adhesive.

32、E84.4.3 Supplementary materials for pipe or duct insulation systems, including tapes, joint sealants, and fitting covers, that areintermittently spaced, shall be tested for flame spread and smoke development as single-component systems, using Test MethodE84.5. Significance and Use5.1 Pipe and duct i
33、nsulation systems are often evaluated with Test Method E84 to comply with building or mechanical coderequirements. This practice describes, in detail, specimen preparation and mounting procedures for single-component pipe or ductinsulation systems and for multi-component pipe or duct insulation syst
34、ems.5.2 The material, system, composite, or assembly tested shall be representative of the completed insulation system used in actualfield installations, in terms of the components, including their respective thicknesses.5.3 Pipe and duct insulation systems consist of a variety of materials and cons
35、tructions.5.4 Some testing laboratories have developed a number of protocols for testing pipe or duct insulation systems which utilizeone generic type of materials, all of them with an insulation core and a jacket. Those protocols are the origin of this practice, whichmakes them generic, to reduce m
36、aterial bias in the standard; they have resulted in the procedures presented in 6.1. The procedurespresented in 6.2 6.5 address other types of pipe or duct insulation systems.5.5 This practice addresses specimen preparation and mounting of systems of the types described in 5.5.1 5.5.3 and testingof
37、supplementary materials as described in 5.6.5.5.1 Multi-component systems containing an insulation core and a jacket, with or without adhesive between insulation core andjacket, not intended to be bonded to a pipe or duct substrate. Specimen preparation and mounting for such systems is describedin 6
38、.1 if they are self-supporting and in 6.2 if they are not self-supporting.5.5.2 Single component systems, not intended to be bonded to a pipe or duct substrate. Specimen preparation and mounting forsuch systems is described in 6.3 if they are self-supporting and in 6.4 if they are not self-supportin
39、g.5.5.3 Systems intended to be bonded to a pipe or duct substrate. Specimen preparation and mounting for such systems isdescribed 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 preparation andmounting described in Practice E2599
40、.5.5.5 Specimen preparation and mounting procedures for systems not described in this practice shall be added as the informationbecomes available.5.6 Supplementary Materials:5.6.1 It is recognized that supplementary materials for pipe or duct insulation systems are normally able to generate heat, fl
41、ameor smoke. Thus, the fire safety of the entire system depends, at least to some extent, on the fire performance of supplementarymaterials. Consequently, the fire-test-response characteristics of all supplementary materials shall be assessed to obtain a fullassessment of the fire-test-response of t
42、he pipe or duct insulation system. See Appendix X1.5.6.2 Supplementary materials are often present intermittently spaced, and not for an extended length, in a pipe or ductinsulation system. Thus, it is not always possible to suitably test them in conjunction with a pipe or duct insulation system.5.6
43、.3 Testing of Supplementary MaterialsSupplementary materials that have not been fully tested in conjunction with the pipeor duct insulation system, in accordance with Section 6, shall be tested for flame spread and smoke development assingle-component systems, in accordance with Test Method E84.5.7
44、The limitations for this procedure are those associated with Test Method E84.E2231 1436.
