BIS CERTIFICATION FOR DOMESTIC ELECTRIC FOOD MIXERS
IS 4250:1980

In this competitive scenario, it isn't easy to survive in the market without a standard quality and certified product. BIS license may also be required to sell products in the Indian market.

To get BIS certification and produce a standard quality product, the manufacturer must ensure that their product must follow the specified Indian standard.

Let's take a closer look at IS 4250:1980 for domestic electric food-mixers.

This standard applies to electric motor-driven food-mixers (liquidizers and grinders) intended for home use and designed to operate at voltages not higher than 250 V. Multipurpose machines used in conjunction with specific accessories are also covered by this standard. This standard specifies the general and safety requirements for domestic electric food mixers used to mix liquids, create slurries or pulps of food, and crush dry foodstuffs. Determining the performance of food-mixers is also an important factor in determining the quality of food-mixers.

Appliances shall be classified into the following classes: Class I, Class II, and Class III.

In addition to the requirements of this standard, the provisions of IS: 302-1979* general requirements shall apply. The external finish used on metal components must be heat and moisture resistant. It must not be negatively affected by temperature changes that occur under normal operating conditions or during the endurance test. The external finish of the food-mixer body shall not get stained as a result of food-stuff spillage from the food-mixer bowl.

Appliances must be built in such a way that they perform securely in normal usage, posing no hazard to the user or the environment, even if carelessness occurs during normal use. This principle is achieved by meeting the relevant requirements described in this standard, and compliance is verified by running the whole applicable test. The applicable provisions of IS302 testing shall apply. Appliances must be built and enclosed in such a way that there is adequate protection against accidental contact with live parts.

Samples of each type of Domestic Electric Food Mixer must be tested in the following ways:

  • Rated voltage
  • Rated input (wattage)
  • Function (grinder/ liquidizer/ centrifugal juicer)
  • Rated Capacity (for a function)
  • Normal Load (in terms of recipe)
  • Time rating
  • Class of appliance
  • Insulation class

Tests

Some of the following tests shall be carried out for domestic electric food mixers.

  • Protection against Electric Shock
  • Input
  • Electric Insulation and Leakage Current at Operating Temperature
  • Provisions of Earthing
  • Insulation Resistance & Electric Strength
  • High Voltage
  • Temp withstand test for Bowl
  • Stability and Mechanical Hazards
  • Test for control
  • Starting

Labelling and marking shall be done in accordance with IS 4250: 1980. Conforming to the requirements of IS 4250: 1980, the product may be certified under the terms of the Bureau of Indian Standards Act, 2016 and the Rules and Regulations formulated thereunder, and the product may be marked with the Standard Mark. The Manufacturer must obtain a BIS license from the Bureau of Indian Standards to use a standard mark. The BIS grants a license based on a successful assessment of manufacturing infrastructure, quality control, testing capabilities, and production process.
