In today's competitive landscape, maintaining market presence without a certified, high-quality product can be challenging. Obtaining a BIS license may also be essential for selling products in the Indian market. To achieve BIS certification and ensure product quality, manufacturers must adhere to the specified Indian standards.
Let's delve deeper into IS 16544:2016 For All Glass Evacuated Tubes Solar Water Heating System. This standard lays down specifications for the design, materials, manufacturing processes, and performance requirements of solar water heating systems using evacuated glass tubes, focusing on critical parameters such as thermal insulation, heat retention, structural integrity, and energy efficiency.
These systems are pivotal for renewable energy adoption, offering high thermal efficiency, durability, and reliability across residential, commercial, and industrial sectors. All Glass Evacuated Tube Solar Water Heating Systems are widely used in residential, institutional, and commercial sectors for energy-efficient hot water solutions. Manufacturers must ensure that design, technical documentation, and the Quality Assurance Plan match the requirements of IS 16544:2016, with type testing required at BIS-recognized labs for critical parameters like thermal efficiency, tube quality, heat retention, and mechanical durability.
| Product Name | All Glass Evacuated Tubes Solar Water Heating System |
| Applicable Indian Standard | IS 16544:2016 |
| Applicable Certification Scheme | Product Certification Scheme (ISI Mark Scheme) Scheme 1 - Schedule 2 |
| Compliance Requirement | Mandatory |
| QCO Link | Quality Control Order |
Mandatory Tests:
Thermal Efficiency Test
Tube Quality/Selective Coating Inspection
Heat Retention Test
Mechanical Durability Test
Insulation Performance Test
Optional Tests:
Absorber Efficiency Test
Structural Integrity Stress Test
Here are the key benefits of getting ISI Mark certification:
Government Quality Assurance: The ISI mark instills consumer confidence in using renewable energy in residential as well as industrial premises, and safeguards users from substandard products.
Mandatory Compliance: All manufacturers and importers of these systems must obtain BIS certification and affix the ISI Mark on their products before introducing them to the Indian market, applying to both domestic production and imports.
Enhanced Market Competitiveness: The product comes under Scheme 1 of BIS certification, helping manufacturers establish their reputation for delivering quality-assured solar water heating systems.
Regulatory Oversight: The Bureau of Indian Standards, in coordination with the Ministry of New and Renewable Energy, undertakes market surveillance to verify adherence to the Indian Standard for products displaying the Standard Mark.
Avoiding Legal Exposure: Non-compliance with this mandate violates Section 29(3) of the BIS Act, 2016, leading to severe consequences including seizure of goods, substantial monetary penalties, cancellation of license, and potential imprisonment.

The estimated duration for securing BIS certification for all glass evacuated tubes solar water heating systems under IS 16544:2016 varies based on the manufacturer’s location and certification route. The typical timelines are outlined below:
| Indian Manufacturers | BIS certification is generally completed within approximately 30 days, subject to successful product testing and documentation verification. |
| Foreign Manufacturers (FMCS Route) | Under the BIS Foreign Manufacturer Certification Scheme (FMCS), the process usually takes around 180 days, considering factory inspection, sample testing, and regulatory approvals. |
Acquiring a BIS license for this product involves a detailed review of the manufacturer's production process, in-house quality control capability, and testing infrastructure. Type testing must be conducted in BIS-recognized laboratories for critical parameters like thermal efficiency, tube quality, heat retention, and mechanical durability, and the manufacturer's technical documentation and Quality Assurance Plan must align with IS 16544:2016 requirements before BIS grants the license.
