BIS Certification for Evaporative Air Coolers (Desert Coolers) IS 3315

The Air Cooler and Air Filters (Quality Control) Order, 2025 (S.O. 529(E), January 30, 2025) - issued by the Ministry of Commerce and Industry (DPIIT) - makes BIS ISI Mark certification mandatory for evaporative air cooler manufacturers. It superseded the earlier QCO 2023 (S.O. 1114(E), March 5, 2024) and came into force on its date of publication.

• BIS is the sole certifying and enforcement authority - no other body issues valid air cooler quality certification for India
• Applies to domestic manufacture and sale - export-only production is exempt
• Declared non-certified stock (by eligible manufacturers) can be sold up to 31 October 2025
• R&D imports: up to 200 units per year exempted - cannot be sold commercially, must be scrapped

IS 3315 has been revised from the 2019 version to IS 3315:2024. As per the QCO note, the latest version of the IS standard as notified by BIS applies - making IS 3315:2024 the mandatory compliance benchmark. The BIS Product Manual was updated to PM/IS 3315/2/October 2024 to reflect this revision.

IS 3315:2024 covers Direct Evaporative Air Coolers - appliances that cool air by passing it through water-saturated pads, causing evaporative cooling through the latent heat of vaporization. The standard covers the complete appliance as a system - enclosure, fan or blower assembly, water pump set, cooling pads, water distribution system, electrical supply cord, switches, and controls.

The standard covers two primary configuration types:

• Metallic enclosure coolers - steel body construction - the traditional desert cooler form factor dominant in India's tier-2 and tier-3 markets
• Non-metallic enclosure coolers - ABS plastic and other polymeric enclosures - covering modern tower coolers, personal coolers, and premium room coolers
• Blower-type - uses centrifugal blower for air delivery - typically found in window-mounted and duct-connected configurations
• Fan-type - uses axial fan for air delivery - common in freestanding room coolers

India's evaporative air cooler market is one of the largest globally - driven by hot, dry climate zones across Rajasthan, Gujarat, Madhya Pradesh, Uttar Pradesh, Haryana, Punjab, Maharashtra (inland), and large parts of southern India. BIS ISI Mark certification is the key to unlocking this market - both for domestic manufacturers and for global manufacturers targeting India through imports.

The BIS Product Manual for IS 3315:2024 specifies the IS standards that govern key components of the air cooler. Components received with test certificates or ISI marks do not require further incoming testing - which directly reduces your in-house testing burden during production and at the BIS audit. Getting your supply chain right before applying for certification is one of the most effective ways to reduce audit risk.

Under Annex A of the BIS Product Manual PM/IS 3315/2/October 2024, every air cooler is identified with a unique model name or number. A variety is defined as a group of models sharing the same values for all six technical parameters below. Each variety must be tested separately for Grant of Licence (GoL) and Change of Scope of Licence (CSoL).

The scope of a BIS ISI Mark licence under IS 3315:2024 is defined in Annex D of the Product Manual. The licence scope explicitly states the product name (Direct Evaporative Air Coolers), the material of enclosure, airflow type, air delivery range, power input, cooling efficiency, and EER - along with an Annexure listing all individual model numbers and their technical parameters.

All model numbers and their technical parameters intended to be covered under the licence must be declared by the manufacturer at the time of application. BIS may restrict the scope based on demonstrated manufacturing and testing capability. During licence operation, BIS ensures all models covered in the licence are tested in rotation to verify continued compliance.

Every single air cooler that carries the BIS ISI Mark must undergo five production routine tests before leaving the manufacturing facility. These are in-house (R - Required) tests - they cannot be subcontracted. Large-scale manufacturers must maintain the equipment for these tests in their own facility.

Additionally, the finish of each unit is inspected - visual examination for surface quality and workmanship. Only coolers that pass all five routine tests plus finish inspection can carry the ISI Standard Mark.

Type tests are periodic tests - conducted once per month - to verify that production continues to meet IS 3315:2024 performance requirements. These can be subcontracted to a BIS-recognised laboratory or any laboratory with valid NABL accreditation under IS/ISO/IEC 17025. Testing must cover all model numbers produced in the month - at least one sample of each model per month.

The BIS Product Manual Annex B specifies the indicative list of test equipment. Large-scale manufacturers must maintain equipment for all routine tests in-house. The equipment needed for type tests (which can be subcontracted) requires specialised setups that most manufacturers will need to access through a BIS-recognised or NABL-accredited laboratory.

All in-house test equipment must have current calibration certificates from accredited calibration agencies. The manufacturer must implement and maintain a calibration plan for all in-house equipment - this is reviewed during the BIS factory audit and during ongoing surveillance inspections.

For MSME air cooler manufacturers, the most practical approach is typically to identify a BIS-recognised or NABL-accredited testing laboratory in your region for routine test outsourcing, while maintaining basic dimensional checking (Vernier caliper) in-house. Standphill India helps MSME clients identify the right testing laboratory partners and plan the most cost-efficient compliance structure before applying for certification.

The BIS Product Manual for IS 3315:2024 defines the recommended Control Unit as the quantity of air coolers with the same model name or number produced in one shift of production. This is the fundamental batch unit against which quality is managed under the BIS scheme.

Manufacturers must define and submit a Quality Assurance Plan (QAP) to their BIS Branch Office - this plan documents the control unit definition, testing frequencies, in-house testing responsibilities, and record-keeping procedures. The manufacturer must comply with the submitted QAP and maintain test records for all tests carried out to establish conformity.

• QAP submitted to BIS Branch Office for information - manufacturer must comply with it
• Test records maintained in-house for all routine tests and type tests
• For subcontracted tests - test reports from BIS-recognised or NABL labs must be available for BIS inspection
• Every air cooler conforming to IS 3315:2024 and covered under the licence scope must carry the ISI Standard Mark
• The licence number (CM/L-________) and BIS website reference must be marked on each cooler or its packaging
• Non-conforming coolers must be disposed of in a manner that prevents violation of the BIS Act, 2016 - they cannot be sold

One of the most practically important provisions of the IS 3315:2024 Product Manual is the model addition process. Once you have a BIS licence, you don't need to go through a full re-application every time you want to launch a new model. The process depends on whether the new model falls within your existing licence scope or requires a new scope.

India's evaporative air cooler market attracts global manufacturers from China, South Korea, Taiwan, Malaysia, the Middle East, and Europe. Any overseas manufacturer supplying air coolers to India - whether through direct imports, brand licences, or Indian distribution partnerships - must hold a valid BIS ISI Mark licence under IS 3315:2024 through the Foreign Manufacturer Certification Scheme (FMCS).

• Authorized Indian Representative (AIR) required - must be appointed before application filing
• Physical application submitted to BIS Headquarters, New Delhi
• BIS factory inspection conducted at the overseas manufacturing facility
• All IS 3315:2024 technical requirements apply identically - no relaxation for foreign manufacturers
• Sample size for FMCS testing: 01 unit per variety (same as domestic)
• FMCS licences carry the CM/L- prefix and are publicly verifiable at www.manakonline.in
• FMCS licences are typically granted for shorter initial periods - renewal tracks compliance over time

Standphill India has delivered FMCS certifications for manufacturers from South Korea - including complex dual-standard projects covering IS 17875:2022 and IS 17876:2022 for HYG Co., Ltd. We bring the same structured, first-attempt approach to FMCS air cooler certifications for overseas manufacturers targeting the Indian market.

Step 1 - Technical Classification and Scope Planning: Map all your models against the six IS 3315:2024 technical parameters. Determine the number of varieties requiring testing. Plan the optimal licence scope to cover your full product range efficiently.

Step 2 - Pre-Audit Factory Gap Analysis: Standphill India conducts a detailed assessment of your manufacturing facility - production process, component sourcing (ISI mark status of fan motor, pump set, supply cord, switches), in-house testing equipment, calibration records, and documentation - against IS 3315:2024 requirements. Every gap is resolved before BIS is involved.

Step 3 - Quality Assurance Plan Preparation: Draft your QAP defining control unit, routine test schedules, type test frequencies, record-keeping procedures, and laboratory arrangements. This is submitted to BIS Branch Office along with the application.

Step 4 - BIS Application Filing: Complete application through BIS ManakOnline portal with all required documents, model declaration with technical parameters for all varieties, and QAP. Application fee and 50% marking fee paid.

Step 5 - Product Sample Testing: One unit per variety is tested at a BIS-recognised laboratory for all applicable IS 3315:2024 parameters - cooling efficiency, air delivery, EER, power consumption, electrical safety, sound, and drop test. Standphill India coordinates sample preparation, submission, and laboratory liaison.

Step 6 - BIS Factory Audit: BIS-nominated auditor inspects the facility - manufacturing process, in-house test equipment and calibration records, component ISI mark/test certificate documentation, and quality records. Standphill India provides on-ground support throughout.
