BIS Scheme X Certification for Centrifuges and Filtering or Purifying Machinery

In today's industrial world, centrifuges and filtration systems are vital for maintaining clean, efficient, and safe operations across sectors such as chemical manufacturing, pharmaceuticals, oil & gas, food processing, wastewater treatment, and more. These machines, responsible for separating, filtering, or purifying liquids and gases, are critical to both process efficiency and environmental safety.

Recognizing the importance of regulating the quality, safety, and performance of these machines, the Bureau of Indian Standards (BIS) has made it mandatory for all types of centrifuges, filtering or purifying machinery for liquid and gas and/or their assemblies, sub-assemblies, and components to be certified under the BIS Scheme X.

This directive comes under the Omnibus Technical Regulation Order, 2024, issued by the Ministry of Heavy Industries, and compliance is required by 28th August 2025.

This blog aims to give manufacturers, importers, and industry stakeholders a clear understanding of the BIS certification process for centrifuges and filtration machinery, why it matters, and how to ensure compliance under the BIS Scheme X certification framework.

What is BIS Certification?

The Bureau of Indian Standards (BIS) is the national standards body responsible for setting product quality benchmarks in India. BIS certification is a process that verifies whether a product or system complies with applicable Indian Standards (IS) related to quality, safety, and performance.

To bring structured regulatory oversight to machinery and electrical equipment, BIS launched the Scheme X Certification on 16th March 2022. This scheme is part of the BIS Conformity Assessment Regulations, 2018, and applies specifically to products like:

• Centrifugal and mechanical separation machines

• Industrial and lab filtration/purification units

• Gas and liquid separation equipment

• Sub-assemblies and components used in such machinery

Under Scheme X, both domestic and foreign manufacturers must obtain BIS certification before their products can be manufactured, sold, imported, or used in India.

Omnibus Technical Regulation Order, 2024: What It Means

TheOmnibus Technical Regulation Order, 2024, mandates that:

“All types of centrifuges, filtering or purifying machinery for liquid and gas and/or their assemblies, sub-assemblies, components must comply with the applicable Indian Standards under BIS Scheme X certification by 28th August 2025.”

This order applies to all manufacturers — Indian and international — and will be enforced strictly after the compliance deadline.

Why This Certification Matters

Centrifuges and filtration or purification systems are exposed to high mechanical loads, fluid pressures, chemical interactions, and continuous use. A minor design flaw or substandard component can result in:

• Contamination of sensitive products (pharma, food)

• Environmental hazards (chemical and oil spills)

• Equipment failure and operational downtime

• Safety risks for operators and workers

Hence, ensuringconformity to Indian Standardsis essential for protecting people, the environment, and industrial productivity.

Scope of Products Requiring Certification

The following machinery categories and components fall under the scope of BIS certification for centrifuges, filtering, or purifying machinery:

Main Equipment:

• Horizontal and vertical centrifuges (basket, decanter, disc stack)

• Ultrafiltration and reverse osmosis systems

• Cyclonic separators

• Gas scrubbers and purifiers

• Membrane filtration systems

• Electrostatic precipitators

• Cartridge and bag filters

• Air purifiers (industrial)

Assemblies and Sub-Assemblies:

• Rotor assemblies, filter housings, bowl drive systems

• Piping modules and control panels

• Valves, pressure vessels, drive mechanisms

Components:

• Membranes, filter media, gaskets

• Motors, pumps, bearings

• Sensors and control interfaces

• Casings, seals, and structural parts

Every unit or component essential for the machine’s safety, function, or structural integrity must adhere to BIS standards.

BIS Scheme X Certification Process

Achieving compliance may seem daunting, but the process is fairly structured:

1. Identify Relevant Standards:Determine the Indian Standards applicable to your specific product type.

2. Product Testing:Samples must be tested in BIS-recognized laboratories. Tests include performance, safety, and endurance checks.

3. Factory Inspection:BIS officials will inspect manufacturing units to assess quality control procedures, machinery, and adherence to production standards.

4. Documentation:Submit all necessary documents, including technical specifications, quality manuals, test reports, and application forms.

5. Grant of License:Once verified, BIS issues a license allowing the use of the Standard Mark under Scheme X.

Why Get BIS Scheme X Certification for Centrifuges and Purifiers?

1. Legal Compliance:Avoid legal penalties, product seizures, and import/export disruptions by obtaining certification before 28th August 2025.

2. Market Access:Certified products can be sold in public tenders, defense procurement, institutional contracts, and large-scale industry projects.

3. Customer Trust:The ISI mark is a symbol of safety and quality that increases customer confidence, especially in regulated sectors like pharma, chemicals, and F&B.

4. Risk Mitigation:Prevent catastrophic failures, product recalls, or environmental accidents due to non-standard machinery or components.

Conclusion

The BIS Scheme X certification for centrifuges, filtering or purifying machinery for liquid and gas, and/or their assemblies, sub-assemblies, and components, is a crucial regulatory milestone for the industrial machinery sector in India.

Whether you’re an equipment manufacturer, importer, EPC contractor, or supplier of components, achieving BIS compliance by the 28th August 2025 deadline will ensure uninterrupted operations, expanded market access, and enhanced credibility.

In a sector where safety, purity, and efficiency are non-negotiable, BIS certification for centrifuges, filtering, or purifying machinery is not just a legal requirement—it’s a mark of excellence.
