BIS Certification for
Low Speed Food Grinding Machines

The BIS Certification of Low-Speed Food Grinding Machines are mandatory under IS 302 (Part 1): 2024/IEC 60335-1 in India. The ISI Mark Certification ensures that products, including meat grinders, grain grinders, and food processors, are safe for use and protects users from electric shock, fire risk, and mechanical hazards. 

Low-speed food-grinding machines have become an important part of modern kitchens due to their ability to grind grains, spices, pulses, and other ingredients with precision and efficiency. As these appliances run on electrical power and contain moving mechanical parts, ensuring their safety is important to avoid electric shocks, overheating, fire hazards, and mechanical injuries. IS 302 (Part 1): 2024/ IEC 60335-1 is a safety standard for household and similar electrical appliances. It complies with the general safety and quality requirements for electrical appliances, including low-speed food-grinding machines.

What are Low-Speed Food Grinding Machines under IS 302 Part 1: 2024/IEC 60335-1?

Low-Speed Food Grinding Machines are electric-powered appliances for grinding, crushing, or milling food materials at lower RPMs (for instance, electric grain grinders with a capacity of up to 3L or wet/dry stone grinders) and comply with the mandatory standards of the Bureau of Indian Standards (BIS).

As per IS 302 (Part 1): 2024 / IEC 60335-1, Low-Speed Food Grinding Machines are electrical kitchen appliances designed to grind, crush, or process food materials (including grains, wet batter, meat, or vegetables) at low speeds. One of the most popular Low-Speed Food Grinding Machines is an electric wet grinder.

Testing Parameters for Low Speed Food Grinding Machines IS 302 (Part 1)/IEC 60335-1

IS 302 Part 1: IEC 60335-1 sets out testing criteria for low-speed food-grinding machines to ensure their electrical safety, mechanical reliability, durability, and quality. During BIS testing, the appliance is evaluated for compliance with the following safety parameters:  

• Protection Against Access to Live Parts: Users can be assured of their safety by preventing accidental contact with live electrical parts.
• Power Input and Current: The appliance will be checked to ensure it operates within its rated power and current limits.
• Leakage Current and Electric Strength at Operating Temperature: Insulation performance will be evaluated, and proof of protection against electric shock will be provided at the operating temperature.
• Moisture Resistance: All appliances will be tested to verify protection against moisture ingress and water exposure.
• Leakage Current and Electric Strength: After all appliances have been exposed to moisture, they will be tested again for electrical insulation.
• Stability and Mechanical Hazards: Appliances that do not remain in place will be checked, and any test performed on a moving part will be conducted to confirm it does not pose a risk of injury.
• Mechanical Strength: Evaluate an appliance's ability to resist impact and mechanical stress from normal use.
• Construction: Constructed in accordance with prescribed safety requirements.
• Internal Wiring: Check the routing, insulation, and protection of internal wiring to prevent damage.
