    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

    Abstract - (Show below) - (Hide below)

    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.
