BIS Scheme X Certification for Centrifuges and Purification Machinery: A 2025 Compliance Guide

bis-scheme-x

In modern industrial environments, centrifuges and filtration systems play a pivotal role in maintaining safe, efficient, and clean operations across a wide range of industries — including pharmaceuticals, chemicals, food processing, oil & gas, and wastewater treatment. These machines are essential for separating, filtering, or purifying liquids and gases, directly impacting both operational efficiency and environmental safety.

To uphold safety, quality, and performance standards, the Bureau of Indian Standards (BIS) has mandated that all centrifuges and filtering or purifying machinery — including their assemblies, sub-assemblies, and components — must be certified under BIS Scheme X.

This requirement stems from the Omnibus Technical Regulation Order (OTRO), 2024, issued by the Ministry of Heavy Industries. Manufacturers are required to achieve compliance by 28th August 2025.

This article provides manufacturers, importers, and industry professionals with a comprehensive guide to BIS Scheme X Certification for centrifuges and filtration machinery, including its benefits, process, and scope.

What is BIS Certification?

The Bureau of Indian Standards (BIS) is India’s official body for setting national product standards across industries. BIS certification confirms that a product adheres to applicable Indian Standards (IS) for quality, safety, and performance.

To bring more structure to the regulation of industrial machinery, Scheme X Certification was introduced on 16th March 2022 under the BIS Conformity Assessment Regulations, 2018. This scheme covers a broad range of products including:

Omnibus Technical Regulation Order, 2024: What You Need to Know

According to the OTRO 2024:

By 28th August 2025, all centrifuges, filtering or purifying machinery for liquids and gases—including their assemblies, sub-assemblies, and components—must comply with relevant Indian Standards and obtain certification under BIS Scheme X.

This regulation applies to all manufacturers — domestic and international — and will be strictly enforced after the deadline.

Why BIS Certification Is Important

Centrifugal and filtration systems are subject to high mechanical stress, chemical exposure, and continuous operation. Faulty design or poor-quality components can result in:

Contamination (especially in pharma and food sectors)
Environmental incidents (e.g., chemical or oil leaks)
Mechanical failures and production losses
Safety hazards for equipment operators

BIS certification ensures that products meet consistent standards to prevent these issues and ensure long-term reliability.

Scope of Products Covered Under BIS Certification

Main Equipment:

Horizontal & vertical centrifuges (e.g., basket, disc, decanter)
Ultrafiltration and RO (reverse osmosis) systems
Cyclone separators
Gas scrubbers and purifiers
Membrane filtration units
Electrostatic precipitators
Cartridge, bag, and HEPA filters
Industrial air purifiers

Assemblies & Sub-Assemblies:

Rotor mechanisms, filter housings, and drive assemblies
Control panels and piping modules
Pressure vessels, actuators, and valves

Components:

Membranes, filter media, seals, gaskets
Motors, bearings, pumps
Electrical sensors and automation controls
Housings, casings, and structural components

All essential parts that impact the safety or performance of the equipment fall under the scope of certification.

BIS Scheme X Certification Process

The certification process under Scheme X is structured and includes the following steps:

Identify Relevant Standards: Determine the Indian Standards (IS) applicable to your product type.
Product Testing: Conduct tests at BIS-approved laboratories covering safety, durability, and performance.
Factory Inspection: BIS officials will inspect the production facility for quality control, process adherence, and compliance.
Document Submission: Provide technical specifications, test reports, quality manuals, and application forms.
License Grant: Upon successful evaluation, a license is issued allowing use of the ISI mark under Scheme X.
Ongoing Surveillance: Certification is subject to renewal and periodic audits to maintain compliance.

Why Obtain BIS Scheme X Certification?

Legal Compliance: Avoid penalties, import bans, and seizure of uncertified products after 28th August 2025.
Market Access: Participate in government contracts, tenders, and large-scale industrial supply chains.
Customer Confidence: Certified products reflect higher safety, quality, and reliability—key in pharma, F&B, and chemical sectors.
Operational Reliability: Minimize the risk of recalls, contamination, breakdowns, or hazardous incidents.

Conclusion

BIS Scheme X Certification for centrifuges and filtration or purifying machinery — including their assemblies and critical components — is a transformative move for India’s industrial machinery landscape.

For manufacturers, importers, and industry players, ensuring compliance by 28th August 2025 is not only a legal obligation but also a strategic investment in brand credibility, operational safety, and long-term market access in India.
