This standard specifies an instrumental method for determining the water vapour transmission rate of plastic film, plastic sheeting and multi-layer structures including plastics, plastics, which have smooth surfaces without any embossed portions, using a humidity detection sensor, method, infrared detection sensor method and gas chromatographic sensor method. NOTE: The corresponding International Standards and the symbol of degree of correspondence are as follows. ISO 15106'1: 2003 Plastics -- Fi]tn and sheeting- Determination of water vapour transmission rate -- Part 1: Humidity detection sensor method ISO 15106-2: 2003 Plastics- Film and sheeting- Determination of water vapour transmission rate -- Part 2: Infrared detection sensor method ISO/DIS 15106-4: 2007 Plastics -- Film and sheeting- Determina- tion of water vapour transmission rate -- Part 4: Gas-chromatographic detection sensor method (Overall evaluation: MOD) The symbols which denote the degree of correspondence in the con- tents between JIS and the relevant International Standards are IDT (identical), MOD (modified) and NEQ (not equivalent) according to ISO/IEC Guide 21.
