| 1 | This standard was originally published in 1985 and subsequently revised in 2014 by adopting the ISO 1663: 2007 under dual numbering system. However while reviewing the ISO 1663: 2007 version by the committee, it was observed that ISO 1663 has been revised as ISO 1663 : 2023. This revision has been taken up in order to align the standard with the latest version of ISO 1663. | |
| 2 | The test method has been updated by changing the unit of water vapour transmission rate from ng to µg. Accordingly, formulae have been modified. | |
