1) The factors used to convert % vol. into % LEL are stated according to the NIOSH Pocket Guide for LEL category 1, according to IEC 60079-20 for LEL category 2, according to Brandes / Möller - Safety Characteristic Data, Volume 1:
Flammable Liquids and Gases (ISBN 3-89701-745-8) for LEL category 3 and according to GOST R 51330.19-99 for LEL category 4. The LEL values according to LEL category 5 "LKLV" (Lowest Known LEL Value) always represent the
lowest of the four other LEL values.
2) Based on LEL values according to IEC, typical tolerances: ±5 % LEL
3) With splash guard
4) No factors for converting % vol. into % LEL for this substance are stated in the reference quoted. The value stated represents (as a minimum value of all other conversion factors) the value shown in the characteristic.
5) No factors for converting % vol. into % LEL for this substance are stated in the reference quoted. The stated value represents the LEL value according to IEC.
