BIS Certification for DC Supplied / Battery-Operated Air Purifiers in India products are subject to mandatory BIS Compulsory Registration Scheme (CRS) requirements in India. Manufacturers and importers must obtain valid BIS CRS registration for each model before the product can be manufactured, imported, or sold in the Indian market. Non-compliance carries penalties including product seizure and prosecution under the BIS Act 2016.
This guide covers the applicable Indian Standards, mandatory safety testing, the step-by-step CRS registration process, document requirements, and the most critical compliance pitfalls for this product category in 2026.
📜 Applicable Indian Standards
The following Indian Standards apply to this product category under the BIS CRS framework:
- IS/IEC 60335-2-65 — Particular requirements for air-cleaning appliances
- IS/IEC 60335-1 — General requirements for safety of household and similar electrical appliances
- IS 13252 (Part 1) — Indian adaptation of IEC 60335-1
- IS 16046 / IEC 62133 — Safety requirements for lithium-ion battery packs (for battery-operated models)
📌 Battery-operated air purifiers with ionisers or UV-C germicidal lamps may attract additional regulatory requirements related to ozone emission limits and UV radiation safety. Identify all functional sub-systems before initiating testing to ensure the full test scope is covered in one round.
🔬 Mandatory Safety Tests
BIS-approved laboratories evaluate the following key areas during safety testing:
Electrical Safety
Insulation resistance, dielectric strength, leakage current, earth continuity, and DC power circuit safety.
Battery Safety
Overcharge, over-discharge, short-circuit, and thermal runaway protection for integrated lithium-ion packs.
Fan & Motor
Motor overload protection, fan blade containment, continuous operation temperature, and noise level.
Thermal
Temperature rise on accessible surfaces, motor winding temperature, and battery pack thermal behaviour under load.
📋 Step-by-Step BIS CRS Registration Process
- Standard ConfirmationVerify the product maps to IS/IEC 60335-2-65. Identify all sub-systems (ioniser, UV-C lamp, HEPA filter motor) that may trigger additional test requirements.
- Appoint AIRForeign manufacturers must appoint an Authorised Indian Representative in India before filing the BIS CRS application.
- Sample TestingSubmit production samples to a BIS-approved laboratory. Testing including battery and sub-system assessment typically takes 4–6 weeks.
- Online ApplicationUpload Form VI, all test reports, factory documents, photographs, trademark certificate, and AIR letter on BIS Manak Online portal.
- Query ResolutionBIS frequently queries ioniser ozone emission data, UV-C lamp shielding evidence, and battery pack test certification. Comprehensive test planning prevents these delays.
- R-Number GrantBIS issues the R-number upon approval. Mark on the unit, battery, packaging, and user manual.
- RenewalValid for 2 years. Changes to the filter motor, battery, ioniser, or UV-C lamp require re-testing.
📄 Documents Required
- Completed BIS Form VI and declaration of conformity
- Test report as per IS/IEC 60335-2-65 from BIS-approved laboratory
- Battery pack test report as per IS 16046 / IEC 62133 (for battery-operated models)
- Ozone emission test data (for ioniser models)
- Factory registration and address proof
- Trademark registration certificate
- AIR appointment letter (for foreign manufacturers)
- Product photographs with label placement
- Technical specification sheet (voltage, airflow, CADR rating, filter type, battery capacity)
- User manual in English and/or Hindi
☠️ Common Rejection Reasons
Common rejection causes include missing battery safety test reports, failure to include ozone emission test data for ioniser models, incomplete fan motor endurance data, UV-C lamp shielding not verified in the test report, and brand name discrepancies between the trademark certificate and product label.
🏭 Special Considerations for Importers
Air purifiers — including compact battery-powered personal air purifiers and desktop models — are a high-growth import category driven by India's urban air quality concerns. BIS enforcement on this category has intensified. Importers must ensure every model has a valid BIS CRS R-number before customs clearance, and must not begin selling through online marketplaces until the R-number is confirmed.
