ADR special provision 382
Expandable polymeric beads need not use this UN number if test U1 shows no flammable vapour forms; test only when de-classifying.
Polymeric beads can be polystyrene, poly(methyl methacrylate) or another polymer. If test U1 (Manual of Tests and Criteria, Part III, 38.4.4) shows that no flammable vapour producing a flammable atmosphere is given off, expandable polymeric beads need not be classified under this UN number. The test is meant only for cases where de-classification is being considered.
Refers to: Manual of Tests and Criteria, Part III, 38.4.4 (test U1).
