  1. Process Safety Testing TRANSPORTATION CLASSIFICATION TESTING (UN / ADR / CLP) The process of safety testing has also covered Transportation Classification Testing (UN / ADR / CLP) and Oxidising Solids. Tel: +44 (0)1962 840570 https://www.sigma-hse.com

  2. OXIDISING SOLIDS PROCESS SAFETY TEST PROCESS The test is conducted primarily for the purposes of transportation. Mixtures of a reference oxidiser (potassium bromate) / cellulose (fuel) and mixtures of the substance and cellulose (fuel) to be tested are prepared in specified ratios. Using a conical funnel the mixtures are formed into a truncated conical pile, covering a looped ignition wire resting on the low heat conducting plate.

  4. OXIDISING SOLIDS Power is applied to the ignition wire and is maintained for the duration of the test. The recorded burning time is taken from when the power is switched on, to when the main reaction (e.g. flame, incandescence or glowing combustion) ends. The test is performed five times on each substance to cellulose ratio and five tests are performed with each reference mixture ratio required to make a Packing Group assignment or to determine if the substance should not be classified in Division 5.1.

  5. FLAMMABILITY OF SOLIDS The test is conducted primarily for the purposes of transportation. A powder strip is formed using a triangular cross sectioned mould, onto a heat resistant, non-porous plate. Using a butane flame, one end of the strip is ignited and the initially the time taken to burn over a marked 200 mm length is recorded. If the time taken is equal to or less than 120 s then further trials are conducted over fresh powder strips and the burning rate over a length of 100 mm measured. If the time taken is equal to or less than 45 s (2.2 mm.s-1) then the material is classified as a ‘Flammable or Combustible Solid, of UN Class 4, Division 4.1.  Tel: +44 (0)1962 840570 https://www.sigma-hse.com

  7. FLAMMABILITY OF SOLIDS During the 100 mm trials, a section of the material past the 100 mm mark is wetted and observations are made to whether the wetted zone, stops flame propagation for at least 4 minutes. If the wetted zone fails to stop propagation the material is designated to packing group 2, if it succeeds, a packing group 3 designation is given. The test method is identical to that detailed within CLP/GHS regulatory procedures and therefore data gathered can be used for both applications. For More Details Click Here.
