BIS Registration for Microwave Ovens in India
IS 302 (Part 2/Section 25):2014 - CRS Process & Global BIS Consultancy
Mandatory Since July 2013 - Strict Enforcement
BIS CRS registration for microwave ovens has been mandatory in India since 3 July 2013 under the MeitY Electronics & IT Goods CRO 2012 (with later amendments). Microwave ovens are one of the longest-standing mandatory CRS products in India - meaning customs and market surveillance for non-compliance is highly active. Selling without a valid BIS R-Number can result in shipment detention, product seizure, and significant penalties.
BIS Registration for Microwave Ovens is mandatory in India under the Compulsory Registration Scheme (CRS). The applicable Indian Standard is IS 302 (Part 2/Section 25):2014 - Safety of Household and Similar Electrical Appliances, Part 2: Particular Requirements, Section 25: Microwave Ovens. This standard is aligned with the international IEC 60335-2-25 framework. Manufacturers and importers - both Indian and foreign - must obtain a BIS R-Number before microwave ovens can be manufactured for sale, imported, or distributed in the Indian market.
What is BIS Registration for Microwave Ovens?
BIS for microwave ovens is the mandatory product registration process administered by the Bureau of Indian Standards under the Compulsory Registration Scheme. It verifies that the microwave oven meets the safety requirements specified in IS 302 (Part 2/Section 25):2014 - including microwave radiation leakage limits, electrical safety, door interlock safety, thermal safety, and mechanical strength.
Once registered, BIS issues a CRS Registration Number (R-Number) that must be displayed alongside the BIS Standard Mark on every certified microwave oven unit. Without this registration, the product cannot legally be manufactured, imported, or sold in India.
- Mandatory for both domestic manufacturers and foreign manufacturers/importers
- Product samples must be tested at a BIS-recognized laboratory with microwave radiation leakage testing capability
- Foreign manufacturers must appoint an Authorized Indian Representative (AIR)
- Validity: 2 years, renewable via BIS Licence Renewal
- Smart microwave ovens with Wi-Fi/Bluetooth additionally need WPC ETA

Microwave Oven Types Covered Under BIS
IS 302-2-25:2014 covers all variants of microwave ovens for household and similar electrical applications. Both Indian-manufactured and imported microwave ovens for the Indian market fall under mandatory BIS CRS:
Solo Microwave Ovens
Basic microwave-only ovens for reheating and defrosting. Most common entry-level units.
Grill Microwave Ovens
Microwave ovens with built-in grill heating element for browning and grilling food.
Convection Microwave Ovens
Combination units with microwave + convection heating for baking, roasting, and full cooking.
Inverter Microwave Ovens
Inverter technology microwaves with variable power output for precise cooking control.
Built-in Microwave Ovens
Integrated kitchen microwave ovens designed for cabinet installation in modular kitchens.
Countertop Microwave Ovens
Free-standing microwave ovens for placement on kitchen countertops - most common form factor.
Smart Microwave Ovens
Wi-Fi/Bluetooth connected microwaves with app control - need both BIS + WPC ETA.
Commercial Microwave Ovens
Commercial-grade microwaves for restaurants, cafés, and food service - subject to same IS 302-2-25 framework.
What is Tested Under IS 302-2-25:2014
Microwave ovens undergo specialized safety testing that goes beyond standard household appliance testing. The most critical test is microwave radiation leakage - which directly impacts consumer health. BIS-recognized laboratories test the following parameters before granting the R-Number:
Microwave Leakage CRITICAL
Measurement of microwave radiation leakage from oven cavity, door seals, and joints. Strict safety limits apply per IS 302-2-25.
Door Interlock Safety CRITICAL
Verification that microwave generation stops immediately when the door is opened. Multiple interlock redundancy testing.
Electric Shock Protection
Insulation, earthing, accessible parts, and protection against electric shock under normal and fault conditions
Thermal Safety
Temperature rise of door handle, accessible surfaces, controls, and internal components under continuous operation
Abnormal Operation
Behaviour under overload, magnetron failure, fan failure, and other fault conditions to verify safe failure modes
Mechanical Strength
Door hinge durability, enclosure impact resistance, and structural integrity of the microwave cavity and frame
Magnetron Safety
High voltage system safety, magnetron cooling adequacy, and protection circuits for microwave generation system
Materials & Components
Cavity material safety (food contact), turntable materials, plastic enclosure flammability, and wiring insulation
Microwave radiation leakage testing is the most stringent test. Even small leakages above the limit cause test failure and require design changes. Standphill India's pre-testing review identifies leakage risk areas (door seals, choke design, hinge gaps) before formal BIS testing - saving manufacturers from costly re-testing rounds.
Smart Microwave Ovens - BIS + WPC ETA Dual Certification
Modern smart microwave ovens with Wi-Fi connectivity, app control, voice assistant integration (Alexa, Google Assistant), or Bluetooth pairing need two certifications simultaneously:
- BIS CRS Registration - under IS 302-2-25:2014 for product safety
- WPC ETA Approval - from the Department of Telecommunications for the wireless radio module
Without WPC ETA, the wireless functionality is illegal to operate in India even if the microwave has BIS registration. Standphill India offers a single-window service handling both certifications under one project - most efficient route for smart appliance manufacturers entering India.
Basic Requirements - 4 Pillars of BIS Registration
BIS CRS registration for microwave ovens stands on four mandatory pillars. All four must be in order before the application can proceed:
Manufacturer
Licence granted to manufacturer only. Foreign manufacturers apply via AIR.
Factory Location
Each manufacturing location needs its own R-Number.
Product Category
One R-Number can cover multiple similar microwave oven models.
Brand / Trademark
Each brand or trademark requires its own BIS licence.
BIS CRS Registration Process
| Step | Activity |
|---|---|
| 1 | Sample testing at BIS-recognized lab under IS 302-2-25:2014 (including microwave leakage) |
| 2 | Foreign manufacturers: nominate Authorized Indian Representative (AIR) |
| 3 | Submit online application on BIS CRS portal (crsbis.in) with CDF, CCL & test reports |
| 4 | BIS technical scrutiny - respond to queries promptly |
| 5 | Grant of BIS CRS Registration Number (R-Number) - valid 2 years |
| 6 | Smart microwaves: WPC ETA application in parallel |
Total timeline: typically 6–10 weeks for BIS CRS + 2–4 weeks WPC ETA (if applicable).
