Why BIS ISI Certification for Sulphate Resisting Portland Cement (IS 12330) Is Mandatory in India

Consider building a bridge, marine construction, sewerage disposal plant, or any construction in sulphate-rich soil. Things look good initially, but after some years, cracks start appearing in your construction. Your concrete gets weaker, repairs become costly, and even the safety of your structure gets affected.

One of the major reasons for such damage is called sulphate attack. In order to avoid it, India has laid down stringent quality requirements for Sulphate Resisting Portland Cement (SRPC) as per IS 12330, thus assuring that only quality cement reaches the markets.

Here comes into picture the need for BIS Certification for Sulphate Resisting Portland Cement. BIS requires adherence to IS 12330 for getting an ISI mark on the product. Whether you are a manufacturer in India or a foreign company intending to supply in the Indian market, getting BIS certification in India will show that your product meets the quality and safety standards required in the country.

In this blog, UMSPCS helps you understand everything about BIS certification of sulphate resisting portland cement.

Understanding about Sulphate Resistant Portland Cement (SRPC)

Sulphate Resistant Portland Cement (SRPC) is a type of cement that does not react with sulphates which are abundant in places where the soil and water contain large amounts of sulphates.

Unlike OPC, SRPC contains a small amount of Tricalcium Aluminate (C₃A).

This is commonly used in:

• Marine constructions
• Coastal constructions
• Sewage treatment plants
• Underground construction
• Structures retaining water
• Bridges
• Dams
• Industrial establishments
• Chemical industry

Foundations subjected to sulphate bearing soil

Why is BIS Certification Mandatory?

Regulation of Cement Products in India by BIS takes place under the provisions of BIS Act, 2016 by the Product Certification Scheme.

The ISI mark cannot be affixed on the cement products unless and until the BIS license is obtained after complying with IS 12330.

Certification provides the assurance that:

• The cement is of prescribed quality.
• The manufacturing process remains constant.
• The testing of the product is conducted regularly.
• Safe and durable construction material is provided to consumers.
• Poor quality cement is kept away from the Indian market.

For Indian manufacturers, this certification is provided under BIS Product Certification Scheme. For foreign manufacturers exporting SRPC to India, certification under FMCS is required.

Products Covered Under IS 12330

The standard applies to:

• Sulphate Resisting Portland Cement manufactured for construction applications
• Cement intended for structures exposed to sulphate-bearing environments
• Cement used in marine construction
• Cement supplied for sewage and drainage infrastructure
• Cement for foundations in aggressive soil conditions

Basic Requirements for BIS Certification IS 12330

Manufacturers must establish a manufacturing facility capable of consistently producing cement conforming to IS 12330.

Basic requirements include:

• Manufacturing unit
• Quality Control Laboratory
• Qualified technical personnel
• Testing equipment
• Documented quality management system
• Manufacturing process controls
• Raw material quality control
• Factory Testing Laboratory

Eligibility Requirements for BIS certification of Sulphate Resisting Portland Cement

1. For Indian Manufacturers

The manufacturers have to satisfy:

• Own a manufacturing plant
• Manufacture cement according to IS 12330
• Have their own testing laboratory
• Adhere to Scheme of Inspection and Testing (SIT)
• Be open for BIS factory inspection

2. For Foreign Manufacturers

Under the BIS Certification for Foreign Manufacturers scheme, the manufacturers have to:

• Own the manufacturing plant
• Appoint an Authorised Indian Representative (AIR)
• Provide necessary technical information
• Undergo BIS factory inspection
• Be compliant with IS 12330

Applicable Tests Under IS 12330

Prior to issuing the certification, BIS ensures the quality of the cement by conducting lab tests. The main tests are:

Physical Tests

• Fineness
• Setting Time
• Soundness
• Compressive Strength
• Heat of Hydration

Chemical Tests

• Insoluble Residue
• Loss on Ignition
• Magnesium Oxide
• Sulphuric Anhydride
• Chloride Content
• Tricalcium Aluminate (C₃A)
• Lime Saturation Factor

The test shows that the cement meets the required quality standards according to IS

Step-by-Step BIS Certification Process for Sulphate Resisting Portland Cement

Step 1: Identify the Applicable Indian Standard (IS 12330)

The first step in the certification procedure starts with identification of the correct Indian Standard for the product. In case of Sulphate Resisting Portland Cement, the manufacturers have to follow IS 12330.

In this stage, the manufacturers have to:

• Familiarize themselves with the technical requirements of IS 12330.
• Ensure that the product is designed and manufactured as per the BIS Standards.
• Improve the process or quality controls if necessary to meet the prescribed standards.

Step 2: Testing and Document Preparation

The product should undergo testing in a laboratory approved by the BIS and accredited by NABL as per IS 12330.

During this stage:

• Testing of product samples as per the relevant standard takes place.
• Preparation of technical and quality related documents.
• Collection of manufacturing and factory details.

Completion of the BIS application along with other documents.

Step 3: Submission of BIS Application

Upon completion of testing and documentation, the manufacturer applies to BIS through its official portal.

A typical BIS application comprises of the following:

• BIS application form
• Test reports of the product
• Factory and manufacturing details
• Relevant declarations and documents
• Government Fees (as applicable)

The BIS reviews the application after which the next stage starts.

Step 4: BIS Factory Inspection

After going through the application, the BIS officials inspect the manufacturing factory to check for adherence to IS 12330.

While inspecting, they verify:

• Manufacturing process
• Production infrastructure
• Quality control process
• In-house testing laboratories
• Adherence to BIS requirements

Samples of products may also be collected for independent lab tests, if necessary.

Step 5: Testing of Samples of Products in Laboratory

Testing of samples of products collected is done in the approved laboratory to ensure that the product satisfies all quality and performance requirements specified under IS 12330.

Lab Test Report (LTR) is submitted to BIS by the laboratory for technical evaluation.

Step 6: Rectification of Defects, If Any

If any defects have been found out by the BIS during inspections and sample testing, then the manufacturer has to rectify those defects before certification is granted.

It could involve:

• Implementation of corrective measures
• Updating of manufacturing or quality control process
• Submission of revised documentation or other information
• Satisfying the BIS requirements

Step 7: Payment of Licence and Marking Fees

Once the product and manufacturing plant pass all the BIS requirements, the manufacturer is supposed to pay the following fees:

• Annual licence fee
• ISI marking fee
• Other BIS fees, if any

Step 8: Grant of BIS ISI Licence

On successful completion of the testing, inspection, compliance check, and payment of fee, BIS provides the ISI licence.

The manufacturer is thus enabled to place an ISI mark on Sulphate Resisting Portland Cement produced in conformity with IS 12330.
