BIS Certification for Split Air Conditioners – IS 1391 (Part 2): 2023

Requirements, Testing & Approval Process Guide

Introduction

With the rapid growth of India’s air conditioning market, ensuring product safety, performance, and energy efficiency has become crucial. The Bureau of Indian Standards (BIS) mandates certification for split air conditioners under IS 1391 (Part 2): 2023.

This certification ensures that every split AC sold in India meets stringent quality benchmarks and carries the trusted ISI Mark, assuring consumers of safety and reliability.

What is IS 1391 (Part 2): 2023?

IS 1391 (Part 2): 2023 is the latest Indian Standard applicable to split air conditioners, covering both residential and commercial units.

It defines the technical, safety, and performance requirements for ACs consisting of:

• Indoor Unit (IDU)
• Outdoor Unit (ODU)

The standard applies to units with cooling capacities typically up to 18,000 W and specifies design, testing, and operational criteria.

It ensures compliance in key areas such as:

• Cooling performance
• Electrical safety
• Energy efficiency
• Noise levels
• Environmental compliance (refrigerants)

Why BIS Certification is Mandatory for Split ACs?

Under the Quality Control Orders (QCOs) issued by the Government of India, split air conditioners must comply with BIS certification to be manufactured, imported, or sold in India.

Key Benefits:

• Ensures consumer safety and protection
• Guarantees energy-efficient performance
• Builds brand trust with ISI mark
• Prevents sale of substandard products

BIS certification confirms that the product conforms to Indian standards and is safe for market use.

Scope of the Standard

IS 1391 (Part 2): 2023 covers:

Types of Split ACs:

• Cooling-only units
• Cooling + Heating (Heat Pump)
• ACs with electric heaters

Configurations:

• Single split systems
• Multi-split systems

Mounting Types:

• Wall-mounted
• Ceiling-mounted
• Floor-mounted

The standard also defines performance under standard rating conditions for cooling and dehumidification.

Key Requirements Under IS 1391 (Part 2): 2023

Manufacturers must comply with the following:

1. Performance Requirements

• Minimum cooling capacity standards
• Efficient airflow and temperature control
• Stable operation under extreme conditions

2. Energy Efficiency

• Compliance with ISEER (Indian Seasonal Energy Efficiency Ratio)
• Reduced power consumption

3. Electrical Safety

• Protection against electric shock
• Insulation and earthing requirements

4. Mechanical & Construction Requirements

• Robust design of indoor and outdoor units
• Quality components (compressor, heat exchangers, fans)

5. Environmental Compliance

• Use of eco-friendly refrigerants
• Limits on ozone depletion and global warming potential

Testing Requirements for BIS Certification

Before approval, split ACs must undergo rigorous testing at BIS-recognized laboratories.

Major Tests Include:

• Cooling capacity test
• Power consumption test
• High voltage test
• Leakage current test
• Earth resistance test
• Pressure/leakage test
• Noise level test
• Maximum operating condition test
• Heating performance test

These tests ensure performance, safety, and durability of the product.

BIS Certification Process for Split Air Conditioners

The certification is granted under Scheme-I (ISI Mark Scheme) of BIS.

Step-by-Step Process:

Step 1: Identify Applicable Standard

Confirm compliance with IS 1391 (Part 2): 2023.

Step 2: Product Testing

• Submit samples to a BIS-recognized laboratory
• Obtain test reports as per the standard

Step 3: Documentation Submission

Key documents include:

• Application form
• Technical specifications & drawings
• Factory layout
• Quality control manual
• List of machinery & testing equipment
• Test reports

Step 4: Factory Inspection

BIS officials inspect:

• Manufacturing process
• Quality control systems
• In-house testing facilities

Step 5: Grant of License

Upon successful evaluation:

• BIS grants the license
• Manufacturer can use the ISI Mark

Step 6: Surveillance & Renewal

• Periodic inspections
• Renewal typically every 1–2 years

Marking & Labelling Requirements

Once certified, the product must display:

• ISI Mark
• Standard number (IS 1391 Part 2: 2023)
• Manufacturer details
• Rated capacity & power consumption

Proper labeling ensures transparency and compliance with BIS norms.

Documents Required for BIS Certification

• Business registration documents
• Manufacturing license
• ISO certification (if available)
• Product design & technical details
• Test reports from BIS labs
• Quality assurance documents

Timeline for BIS Certification

• Indian manufacturers: ~30–45 days (approx.)
• Foreign manufacturers: 3–6 months

Time may vary depending on testing and inspection outcomes.

Penalties for Non-Compliance

Selling non-certified split ACs in India may lead to:

• Product seizure
• Cancellation of license
• Heavy fines
• Legal action under BIS Act

Conclusion

BIS Certification under IS 1391 (Part 2): 2023 is essential for ensuring that split air conditioners in India meet the highest standards of quality, safety, and energy efficiency.

For manufacturers and importers, obtaining this certification is not just a regulatory requirement—it is a strategic step toward building consumer trust and market credibility.
