Administrative data
Link to relevant study record(s)
- Endpoint:
- oxidising solids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
2012-08-01 to 2012-08-08- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: The study is regarded as reliable without restrictions because it was conducted in compliance with GLP regulation and guideline.
- Qualifier:
- according to guideline
- Guideline:
- other: UN test O.1 (UN "Manual of Tests and Criteria", ST/SG/AC.10/11/Rev.5, 2009, 34.4.1)
- Deviations:
- no
- Principles of method if other than guideline:
- The test is designed to measure the potential for a solid substance to increase the burning rate or burning intensity of a combustible substance when the two are thoroughly mixed. In this test certain mixtures of the test substance and of the reference substances with cellulose are formed to a defined conical pile. After electrical ignition on a plate with low thermal conductivity the mean burning time from five trials is determined. If the mean burning time of the substance mixture with cellulose (lowest of the two ratios 4:1 and 1:1) is less than that of a 3:7 mixture of potassium bromate with cellulose the criterion for Div. 5.1 is fulfilled. In this case further reference mixtures (2:3 and 3:2 ratios of potassium bromate and cellulose) have to be tested in order to find the assignment of the substance to the different packing groups (PG I – PG III) in Div. 5.1.
The test criteria for determining oxidizing properties of the substance are:
Packing Group I: any substance which, in the 4 :1 or 1:1 sample to cellulose ratio (by mass) tested, exhibits a mean burning time less than the mean burning time of a 3:2 mixture, by mass, of potassium bromate and cellulose.
Packing Group II: any substance which, in the 4 :1 or 1:1 sample to cellulose ratio (by mass) tested, exhibits a mean burning time equal to or less than the mean burning time of a 2:3 mixture, by mass, of potassium bromate and cellulose; and which does not meet the criteria for packing group I
Packing Group III: any substance which, in the 4 :1 or 1:1 sample to cellulose ratio (by mass) tested, exhibits a mean burning time equal to or less than the mean burning time of a 3:7 mixture, by mass, of potassium bromate and cellulose; and which does not meet the criteria for packing groups I and II.
Not Division 5.1: any substance which, in both the 4 :1 or 1:1 sample to cellulose ratio (by mass) tested, does not ignite and burn, or exhibits mean burning times greater than that of a 3:7 mixture (by mass) of potassium bromate and cellulose. - GLP compliance:
