CERN 05/18 2010Tests for Flammability of Plastic Materials for Parts in Devices and Appliances
1.1 These requirements cover tests for flammability of polymeric materials used for parts in devices and appliances. They are intended to serve as a preliminary indication of their acceptability with respect to flammability for a particular application.
1.1 revised June 2, 2006 1.2 The methods described in this Standard involve standard size specimens and are intended to be used solely to measure and describe the flammability properties of materials, used in devices and appliances, in response to a small open flame or radiant heat source under controlled laboratory conditions.
For the MUV scintillator we tested and compared the flammability of four different type of PLEXIGLASS (PMMA) in plate, which can be used in the experiment.

Polystyrol 143 E GR 2 crystal clear 00013
Saint -Gobain crystals BC-408
In this test we need to have five samples by material with the following dimension : Length : 125mm / Width 13mm / Thickness 13mm
UL94 serves as a preliminary indication of a plastic’s acceptability for use as part of a device or appliance with respect to its flammability. It is not intended to reflect the hazards of a material under actual fire conditions.
V-0 Vertical Burn Burning stops within 10 seconds after two applications of ten seconds each of a flame to a test bar. NO flaming drips are allowed.
V-1 Vertical Burn Burning stops within 60 seconds after two applications of ten seconds each of a flame to a test bar. NO flaming drips are allowed.
V-2 Vertical Burn Burning stops within 60 seconds after two applications of ten seconds each of a flame to a test bar. Flaming drips ARE allowed.

Thanks for your attention test UL 94V in a reason of their fast and high flammability. All 4 samples burn after the first exposure of 10 seconds to the bec Bunsen and the presence of flaming drips and toxic smokes.
