IS (Indian Standard) 60335

Navigating the complexities of electrical safety is paramount for market entry in India. The IS 60335 series (aligned with IS 302) serves as the primary safety framework for household and commercial appliances, ensuring they are resilient against electrical and mechanical failures.

  • Risk Mitigation: Shields manufacturers from liability by adhering to global safety benchmarks.
  • Market Access: Essential for securing the ISI Mark and meeting Quality Control Orders (QCO).
  • Consumer Trust: Guarantees protection against shock, fire, and thermal hazards.
  • Global Alignment: Harmonized with IEC standards for easier international expansion.

Primary Regulatory Framework

The governing standard is IS 302 (Part 1): 2024, which has recently been updated to align with IEC 60335-1: 2020. This "General Requirements" standard must be read in conjunction with the specific Part 2 standard relevant to your specific product category.

Product Taxonomy

This framework covers a vast array of electrical equipment, including but not limited to:

  • Climate Control: Electric fans, air conditioners, and room heaters.
  • Kitchen Essentials: Microwave ovens, mixers, grinders, and induction cooktops.
  • Personal Care: Hair dryers, shavers, and electric irons.
  • Water Treatment: Storage and instantaneous water heaters.

Technical Scope of Evaluation

Testing is rigorous and designed to simulate years of appliance use. Critical parameters include:

  • Protection against Access to Live Parts: Ensuring enclosures are finger-safe.
  • Input Power & Current: Verification of rated values.
  • Heating & Abnormal Operation: Testing under "locked rotor" or "fan failure" conditions.
  • Leakage Current & Dielectric Strength: Assessing insulation at operating temperatures.
  • Mechanical Strength: Impact and drop testing of the outer casing.

Lab Accreditation Requirements

For BIS Certification, test reports must originate from a lab that holds NABL Accreditation (ISO/IEC 17025) and is formally recognized by the Bureau of Indian Standards (BIS). Reports from non-recognized labs will not be accepted for the ISI marking process.

Certification Lifecycle

  • Testing Phase: 15–25 working days (subject to product complexity).
  • Audit & Review: 15–30 days for BIS officer factory inspection and sample sealing.
  • Total Lead Time: Typically 2 to 4 months from the initial application to the grant of the license.

Logistics for Testing Samples

  • Main Unit: 2 to 3 complete sets of the appliance.
  • Critical Components: Additional samples of power cords, switches, thermostats, and internal motors may be required for independent component-level testing.

Financial Investment

The cost structure is divided into:

  1. Laboratory Testing Fees: Dependent on the "Part 2" complexity.
  2. BIS Application & Audit Fees: Official government charges.
  3. Annual Marking Fee: Minimum marking fee payable to BIS based on production volume. For a customized quote, please contact our consultancy team directly.

Mandatory Compliance Dossier

To initiate the process, the following documentation must be finalized:

  • Technical Specifications: Circuit diagrams, PCB layouts, and critical component lists (CCL).
  • Legal Documents: Proof of manufacturing premises (GST/Udyam) and brand registration.
  • User Manuals: Instructions in English and Hindi including safety warnings.
  • Factory Details: List of in-house testing equipment and manufacturing machinery.

Frequently Asked Questions

The 2024 revision aligns Indian standards with IEC 60335-1:2020. It introduces mandatory requirements for battery-operated appliances and cybersecurity protocols, ensuring Indian products meet modern global safety benchmarks.
