Evaluation of the interlaboratory test 2015 – 2016 on the method UN Test L.2 “Sustained combustibility test” / EN ISO 9038:2013 “Determination of sustained combustibility of liquids"

  • The test methods UN Test L.2 / EN ISO 9038:2013 DIN EN 15188:2007 are applied to characterize the sustained combustibility of liquids i.e. the behaviour of a material under specified test conditions, whereby its vapour can be ignited by an ignition source and sufficient flammable vapour is produced to continue burning for at least 15 s after the source of ignition has been removed. The aims of this interlaboratory test (IT) are the verification and/or the improvement (if necessary) of the verification data (reference material) in Annex B of EN ISO 9038:2013, the assessment of influencing (disturbing) factors (laboratory specific factors, which possibly may have an influence on the test result) and the assessment of the performance of the participating laboratories. It could be demonstrated that the reference materials n-Dodecane, n-Decane and n-Undecane as mentioned in the standard are suitable and the verification shall continue to be valid.

It could be demonstrated that the reference materials n-Dodecane, n-Decane and n-Undecane as mentioned in the standard are suitable and the verification shall continue to be valid. Sustained combustibility tests are influenced by several factors like the presence of a draught shield, the experience of the laboratory assistant, verification of the apparatus, calibration of the metering device. Based on the interlaboratory test, the gained experience and the actual results, well-founded measures / actions can be recommended to improve execution of the method. The IT was organized by PTB, BAM and QuoData GmbH in the framework of the co-operation project CEQAT-DGHS Centre for Quality Assurance for Testing of Dangerous Goods and Hazardous Substances.zeige mehrzeige weniger
