Safety Testing IS 16046 – 2 : 2018 Lithium System Cells & Batteries

The primary regulatory framework is IS 16046 (Part 2): 2018, titled "Secondary Cells and Batteries Containing Alkaline or Other Non-Acid Electrolytes — Safety Requirements for Portable Sealed Secondary Lithium Systems". This standard is fully harmonized with the international IEC 62133-2: 2017 guidelines, ensuring global compatibility for manufacturers.

The scope extends to all portable applications utilizing secondary lithium systems. This includes, but is not limited to:

• Consumer Electronics: Mobile phones, smartphones, and tablets.
• Computing Devices: Laptops, notebooks, and portable workstations.
• Power Storage: Power banks and portable energy storage units.
• Portable Appliances: Bluetooth speakers, smartwatches, and handheld medical devices.

To achieve BIS registration, samples undergo rigorous "Intended Use" and "Foreseeable Misuse" simulations:

• Electrical Integrity: Overcharge, external short-circuit, and forced discharge.
• Environmental Endurance: Thermal abuse (130°C), temperature cycling, and low-pressure altitude simulation.
• Mechanical Strength: Free-fall (drop), vibration, mechanical shock, and crush testing.

Testing must be performed exclusively in BIS-recognized labs or NABL-accredited facilities within India. Foreign test reports are generally not accepted for the final BIS application; the product must be physically tested in a domestic facility to ensure compliance with the specific Indian Standard.

A typical certification cycle spans 15 to 30 working days.

• Testing Phase: 7 to 10 days (subject to sample performance).
• Review & Application: 3 to 5 days.
• BIS Scrutiny & Grant: 10 to 15 days (depending on the workload at the Bureau).

For a smooth testing process, manufacturers generally need to provide:

• Battery Packs: 25-30 units.
• Individual Cells: 40-50 units (required even if only the battery is being certified).
• UN 38.3 Report: To facilitate the safe transport of samples to the lab.

The investment for IS 16046-2 registration consists of:

1. Testing Charges: Payable to the BIS-recognized lab.
2. BIS Official Fees: Includes application fees and annual marking fees.
3. Professional Service Fees: For documentation, AIR services (for foreign OEMs), and portal management. Contact us for a customized quote based on your specific cell/battery configurations.

A successful application requires a meticulous document package:

• Technical Specifications: Data sheets for both cells and batteries.
• Brand Authorization: Proof of Trademark or Authorization Letter (Form-I).
• AIR Appointment: Authorized Indian Representative documents (for non-Indian manufacturers).
• Manufacturing Details: Business license, ISO 9001 certificate, and factory flow charts.
