Question
For the Standard IEC 60730-1 4th Ed. there is required:
, L% X& r$ r2 p5 s0 P* Z% YThe solvents used are:
% v5 b) T6 Z8 r7 p( N) _– neutral liquid detergent blended from alkyl benzene sulphonate and non-ionic detergents;
+ b8 `& v- Q. g3 b; D– petroleum spirit (aliphatic solvent hexane with a content of aromatics of maximum 0,1 volume %, a
Kauributanol value of 29, initial boiling point of approximately 65 °C and dry point approximately 69 °C, and
specific gravity of approximately 0,68 g/cm3); and water.
For the standard IEC 60335-1 5th Ed. There is now required:
The petroleum spirit to be used for the test is aliphatic solvent hexane.
- For the standard IEC 60598-1 7th Ed. There is required:
NOTE The petroleum spirit used should consist of a solvent hexane with a content of aromatics of
maximum 0,1 % by volume, a value of 29 % for kauri-butanol, an initial boiling-point of approximately 65
+ S! @0 d8 _+ b6 c0 v+ J°C, a dry-point of approximately 69 °C and a densit y of approximately 0,68 g/cm3.

content of 0,1 % by volume, a kauributenol value of 29, an initial boiling point of approximately 65 °C, a dry
point of approximately 69 °C and a mass per unit vo lume of approximately 0,7 kg/l.
As an alternative, it is permitted to use a reagent grade hexane with a minimum of 85 % as n-hexane.
NOTE The designation “n-hexane” is chemical nomenclature for a "normal" or straight chain hydrocarbon.

The exact chemical solvent formula is difficult to find in the marketplace.
The various TCs are kindly requested to consider "harmonizing" the solvent accordingly.
