BIS Certification for Storage-Type Electric Water Heaters IS 302 (Part 2/Sec21)

Stationary storage-based electric water heaters are important home appliances that provide heated water for long periods of time and provide immediate access to hot water when needed. As they are used commonly in households, the Certification of the product becomes crucial. BIS Certification for storage-type electric water heaters (Commonly known as geysers) is mandatory in India to ensure product safety and quality. These appliances must comply with IS 302 (Part 2/ Sec 21) before being sold in the market.

 

Non-compliance product may lead to penalties or product bans. BIS certification under IS 302 (Part 2/Sec 21) is essential for ensuring that storage-type electric water heaters meet Indian safety standards. It not only ensures compliance but also enhances brand credibility in the market. ERCS Private Limited can help you obtain the ISI Mark for your product easily and efficiently. Know everything before applying for the ISI mark, including product highlights, specifications, the certification process, test parameters, and required documents. Get started today!

 

Overview of Storage-Type Electric Water Heaters

Electric storage water heaters (also referred to as geysers) provide hot water in a consistent manner by pre-heating water prior to delivering it to multiple users in the same household. The lower price of an electric storage water heater, plus its longevity of 10-15 years and ease of installation, make them very attractive choices for many homes and families that require a consistent supply of hot water.

 

IS 302 (Part 2/Sec 21) is the Indian Standard for electrical safety for stationary storage-type electrical water heaters. This standard establishes the minimum electrical safety requirements for stationary storage electric water heaters and covers all aspects of safety and performance of household appliances, as well as energy-efficient operation of household appliances.

 

Key Highlights for IS 302 (Part 2/Sec 21)

The detailed standard for water heating appliances, established by the Bureau of Indian Standards (BIS), which addresses all significant concerns of water heater manufacturers and end-users through its specific verification requirements, such as:

• Safety requirements (key aspect): This standard provides detailed requirements to prevent injury from electrical shock through adequately designed insulation resistance, as required by the House of Testing and by the BIS certificate for appliances for heating domestic water.
• Thermal safety and reliability: This standard has strict minimum testing guidelines to protect against overheating.
• Construction and durability: The standard specifies what materials must be used and their parameters for strength, integrity, and corrosion-resistance through the requirements defined within the BIS certificate for appliances that supply water to be kept stationary in a container.
• Performance testing procedures: This will ensure that the heater performs optimally by evaluating the performance of the appliance through energy consumption and energy efficiency at both the heating and standby states.
• ISI Mark: A manufacturer who has applied for an ISI logo to their category as required by the BIS Quality Control Order to indicate compliance with IS/ISO/IEC 17025 as required by the BIS Quality Control Order.
• Scope and coverage: This standard applies only to stationary hot-water heaters that are intended for residential and similar applications as defined by the standard in the year 2011.

 

Benefits of BIS Certification for Storage-Type Electric Water Heaters

Key benefits of BIS certification for Storage-Type Electric Water Heaters include:

• Mandatory Legal Compliance: It is required to sell, distribute, or import electric water heaters in India.
• Enhanced Consumer Safety: Products meet strict standards for insulation, grounding, and thermal safety (preventing overheating), reducing risks of electrical accidents or fire.
• Quality and Reliability: Ensures the product is durable, efficient, and tested for performance (e.g., hot water output, standing loss).
• Consumer Confidence & Trust: The ISI mark provides assurance, making it easier for customers to choose reliable products, which improves brand image.
• Market Competitiveness: Certified products are often preferred in public and private tenders and stand out in the retail/e-commerce market.
• Reduced Product Failures: The rigorous testing process helps minimize manufacturing defects, reducing returns and warranty issues

Applicable Test Parameters for IS 302 (Part 2/Sec 21)

The following tests are performed as per IS 302-1 (General Requirements), and additional but specific tests are undertaken as per IS 302-2-21:

• Marking & Instruction: Verification of permanent marking, capacity of the product in liters, and user instruction manuals.
• Protection from Shock: Verification of adequate enclosure and insulation to prevent contact with live parts.
• Power Input & Current: Verification of input values to ensure that they meet allowable tolerances for rated input.
• Heating (Temperature Rise): Verification of maximum water temperature rise and exterior temperature rise during normal service operation.
• Leakage Current & Electric Strength: Test and measurement of leakage current and electric strength at operating temperatures and after completion of moisture resistance testing.
• Moisture Resistance: Verification that the ingress of moisture will not affect the insulation.
• Overload & Abnormal Operation: Verification of thermal cut-out and thermostat operation during dry heating and other abnormal operating conditions.

 

Process of ISI Certification of Storage-Type Electric Water Heaters

Manufacturers need to understand the following steps required to get a product certification from the Bureau of Indian Standards.

• Application to BIS: In order to submit their application for a license for the manufacture of the products, the manufacturers must register with the BIS portal.
• Documentation for Application: As part of the application preparation process, manufacturers will need to collect, assemble, and organize all required documentation associated with the product, such as Quality Control Certificates, Factory Licenses, etc.
• Laboratory Testing: Any manufacturer must send samples of their products to an approved laboratory designated by BIS for chemical testing of the components.
• Component Inspection: All production processes will be evaluated and approved by BIS, including the layout of the manufacturing facility and the quality control measures that are in place during production.
• Certification Grant: BIS will provide the manufacturer with the appropriate license for the application of the Standard Mark to their product.

 

Both Indian and foreign manufacturers must follow the process to obtain Product Certification:
