Significance and Use4.1 This standard is intended to be used by engineers and designers as a guide to assist them in selecting appropriate thermalinsulation jacketing materials. As a guide, it can be used to identify

27、performance characteristics that might be necessary for aparticular insulation jacketing system. This guide is not a specification and therefore should not be used as such. It might, however,be useful in writing a specification. Specification C921 can also be used to determine properties of jacketin

28、g materials for thermalinsulation.5. Materials and Manufacture5.1 Jacketing materials may be composed of a single material or a lamination of several components. The material may be inthe form of rolls or sheets or preformed to fit the surface to which they are to be applied. The materials may be ap

Physical and Chemical Performance Considerations6.1 This section includes a number of performance issues that should be considered when using this guide to select a jacketingmaterial for thermal insulation.

48、Some may not be applicable to the particular application. However, to be certain none areoverlooked, the user should consider all materials initially and then eliminate those that are not applicable.6.2 Abuse ResistanceConsideration should be given to the ability of a jacketing material to withstand

49、 a variety of physicalconditions in excess of required functional design criteria. Prior to selection, consideration should be given to the expectedintensity and types of abuse as well as the length of time the jacketing material is expected to withstand a given level of abuse.6.2.1 Abuse May Include the Following Factors:6.2.1.1 Foot traffcWill people or equipment be applying loads directly on the jacketing material such as when piping is usedlike a ladder?6.2.1.2 Impact ResistanceIs the jacketing material located where there is a probability of it being routine
