Introduction
1 Scope
2 Normative references
3 Terms and definitions
4 Test methods
4.1 Fibre release test (refer to annex A)
4.2 Snagging test (refer to annex B)
4.3 Equilibrium moisture content (refer to annex C)
4.4 Oil absorbency (refer to annex D and annex E)
5 Test report
Annex A (normative) Fibre release from wipers

Annex E (normative) Rate of absorbency
Figures
This European Standard specifies testing procedures for fibrous wipers to be used with equipment normally containing electrical insulating oil. Such testing is necessary to rank commercial products, so that possible contamination of insulating oil and electrical equipment with fibres during maintenance operations may be minimized.
