T1 - A new halogen-free flame retardant based on 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide for epoxy resins and their carbon fiber composites for the automotive and aviation industries N2 - The pyrolysis and fire behavior of halogen-free flame-retarded DGEBA/DMC, RTM6 and their corresponding 60 vol.-% carbon fibers (CF) composites were investigated. A novel phosphorous compound (DOPI) was used. Its action is dependent on the epoxy matrix. DGEBA/DMC and DOPI decompose independently of each other. Only flame inhibition occurs in the gas phase. RTM6 shows flame inhibition and a condensed phase interaction increasing charring. Both mechanisms decrease with increasing irradiance, whereas in RTM6-CF charring is suppressed at low ones. RTM6+DOPI shows a higher LOI (34.2%) than DGEBA/DMC+DOPI and a V-0 classification in UL 94. Adding CF only enhances the LOI, DOPI+CF leads to a superposition in LOI for DGEBA/DMC-CF+DOPI (31.8%, V-0) and a synergism for RTM6-CF+DOPI (47.7%, V-0).

This test was introduced into the UN Manual of Tests and Criteria in 1995 as a replacement for a similar test from 1986. Even if the UN O.1 test as described in the current 5th revised edition of UN Manual of Tests and Criteria gives some improvements compared to the old test, which had had many deficiencies, there are still some problems left with this test in terms of e.g. repeatability or reproducibility of test results, how to handle compacted or multilayer formulations like tablets, toxicity and partly significantly varying particle size distribution within defined fractions of 150 μm to 300 μm of the reference oxidizer potassium bromate (KBrO3). For this reason the IGUS EOS working group installed an ad-hoc working group in 2002 assigned with the task to propose solutions for the existing problems. The appropriateness of such proposed solutions has to be proved by the method of interlaboratory (round robin) tests before they are presented for the adoption to the UN Committee of Experts on the TDG and on the GHS with a proposal of a completely revised test procedure.

This paper highlights some of the features and advantages of using organic peroxides especially di-tert-butyl peroxide (DTBP) in high temperature process industries. The feasibility of using DTBP as a main or supporting fuel in process industries have also been justified with the help of Computational Fluid Dynamics (CFD) simulations. For peroxides requirement of less fuel and air for the same amount of heat flux has been shown. The resulted emission from the combustion of DTBP is also discussed.

T1 - Evaluation of the interlaboratory test on the method UN O.2 / EC A.21 'Test for oxidizing liquids' 2009 - 2010 N2 - For the classification of chemicals, special standardized test procedures have been developed and are used world-wide. Safe handling and use of these chemicals depend on the correct classification which therefore must be based on the precise and correct execution of the tests and their evaluation. In this context interlaboratory tests (round robin tests, interlaboratory comparisons / intercomparisons) are a crucial element of a laboratory's quality system. Participation in interlaboratory tests is explicitly recommended by the standard ISO/IEC 17025. The present document reports on the results of the interlaboratory test 2009/2010 on the test methods UN O.2 “Test for oxidizing liquids” [1] / EC A.21 “Oxidizing Properties (Liquids)” [2] which was organized by the Center for Quality Assurance for Testing of Dangerous Goods and Hazardous Substances. The test methods UN O.2 and EC A.21 are applied to characterize the oxidizing properties of liquid chemical substances or mixtures. To differentiate between chemicals with hazardous / dangerous oxidizing properties and chemicals which are not classified as hazardous / dangerous, the substance’s oxidizing properties are compared to those of a standard reference substance. Since the methods (UN O.2 / EC A.21) were developed and came into force in the early nineties a systematic review concerning the practical application of the test method has not been carried out.
