CEN/TC 207 WG 9
Paris Meeting 19/20 June 2012
Sitting furniture / test methods burning behaviour
- round robin RIP cigarettes (Reduced Ignition Propensity)
- revision EN 1021-1 (cigarette test) and EN 1021-2 (flame test) of sitting furniture
- revision EN 597-1 (cigarette test) and EN 597-2 (flame test) of mattresses
The round robin tests on RIP cigarettes showed that about 80% of the cigarettes continue to burn till the end and that the methods to determine the RIP character and the test methods for sitting furniture are very different. Other methods to circumvent the RIP behaviour have been tested, but they had no or little influence.
These results led to the decision to use RIP cigarettes without filter tip that are available on the market for both EN 1021-1 and EN 597-1 and to raise the number of tests from two to three if needed: i.e. if one of the first two cigarettes stops extinguishes, a test with a third cigarette will be carried out. Also a number of clauses of a rather technical nature will be adapted.
EN 1021-1 and EN 1021-2 will be published and submitted to a first vote. The comments will be discussed by mid-2013.
In the meantime, EN 597-1 and EN 597-2 are being prepared. The comments on both EN 1021 standards are waited for, because the adaptations will be roughly similar. In this way, the revision of EN 597 will be quick.
The meeting also discussed the possibility and/or necessity to develop a method with a stronger ignition source next to the cigarette and flame test. At present, several countries (such as the UK, France and Italy) are using different methods. No decision for or against has been taken, but it was asked to verify on a national level whether this proposal can be supported.
