Abstract

This Japanese Industrial Standard specifies the thermal insulation materials mainly used for dwellings or buildings at the ordinary temperature (hereafter referred to as thermal insulation materials). This Standard is not applicable to the heat insulation materials used under atmospheric conditions of particular temperature and humidity such as a cold-storage warehouse, and the heat insulation materials used for facility equipment, piping, etc. for dwellings or buildings. This Standard is applicable to the cellular plastic thermal insulation materials in which fluorocarbons 1) are not used as a foaming agent. The comparison table between previous and current editions of this Standard on technically significant revisions is given in Annex 1. Note 1) Generic term for hydrofluorocarbon (HFC), chlorofluorocarbon (CFC) and hydrochlorofluorocarbon (HCFC). Hydrofluoroolefin (HFO) (HFO-1233zd, HFO-1336mzz and others) does not fall under this category.
