FOREWORD
INTRODUCTION
1 Scope
2 Normative references
3 Terms and definitions
4 General principles for the sampling of insulating
  liquids
Annex A (informative) - Procedure for sampling at
        intermediate levels (making up of the
        average sample)
Annex B (informative) - Procedure for testing the
        integrity of the syringes

IEC 60475:2011 is applicable to the procedure to be used for insulating liquids in delivery containers and in electrical equipment such as power and instrument transformers, reactors, bushings, oil-filled cables, oil-filled tank-type capacitors, switchgear and load tap changers. The main changes with respect to the previous edition are as follows:
- withdrawal of askarels;
- addition of recommendations concerning general health, safety and environmental protection;
- additional details regarding the sampling of oil from electrical equipment, using various types of sampling devices appropriate for the different types of oil tests to be performed in the laboratory.
