Household and similar electrical appliances – Safety – Part 2-7: Particular requirements for washing machines

In this modern aeon, washing machines are necessity of every house. Affording a maid or servant for washing clothes is too much as compared to the cost that washing machine takes. After spending a tiring day at office and look to clean a bundle of clothes at home can be unmanageable. These machines offer the advantage of performance, productivity, simplicity, and less cost.

The above standard deal with safety of electric washing machines (household or similar use that are manufactured to wash clothes and textiles having rated voltage less than 250V for single phase and 480 V for other appliances.

This standard does not covers

  • Washing machines intended for industrial purposes
  • Appliances intended to be used in location where special conditions prevail.

This standard covers the common hazards introduced by washing machines that are experienced by all persons in and around home. Although, in general, it does not take account
