ISI / BIS Certification for Geotextiles used in Subsurface Drainage Application

Applications of Geotextiles in Subsurface DrainageIn a variety of construction and civil engineering applications, geotextiles play a vital function in controlling excess water and reducing soil erosion. They are an integral part of subsurface drainage systems. These specialty textiles are positioned carefully within drainage systems to maximize water flow and filtration. They are composed of strong, permeable materials. Geotextiles are usually employed as a filter and separation layer in subsurface drainage applications. They ensure that water flows freely by keeping fine soil particles from penetrating and blocking drainage pipes or buildings. Geotextiles support soil particle blockage and water flow, preserving the drainage systems' long-term effectiveness.

The Indian Standard IS 16393:2015 lays forth specifications for geotextiles used in subsurface drainage applications. The standard outlines a number of technical specifications for the planning, building, and functionality of geotextiles for subsurface drainage. Geotextiles used in drainage applications are legally required to adhere to these set requirements. Producers that follow these guidelines make sure their goods meet legal requirements, which lowers the possibility of legal problems and liabilities. 

Note: The mandatory ISI Mark Certification is required of manufacturers of geotextiles used in subsurface drainage applications.

In order to guarantee the dependability, efficiency, and efficacy of geotextile materials—which are essential for controlling water flow and halting soil erosion in a variety of environmental and civil engineering projects—ISI certification is an essential quality assurance step. With this certification, geotextiles have proven they can withstand rigorous testing and meet strict requirements defined by the BIS. These requirements are especially designed to assess the geotextiles' strength, permeability, and appropriateness for subsurface drainage. It guarantees that the design and production of these geotextile materials efficiently permits water flow while avoiding soil particles from blocking drainage systems.

About ISI / BIS Certification

Indian Standards Institute, or ISI was renamed the Bureau of Indian Standards (BIS) in 1987. The official mark that the Bureau of Indian Standards provides for manufacturers of various goods is the ISI Mark. It is used to indicate compliance with Indian standards (IS) set by the Bureau of Indian Standards (BIS) and has been used as a conformity marking for industrial products. Manufacturers received permission from BIS to use the ISI Mark on items that comply with relevant Indian requirements through the product certification program. 

Only manufacturers (domestic or foreign) who produce the finished product will be awarded ISI Certification. This will not be given to any product importers, traders, dealers, or distributors.

Documents Required for ISI / BIS Certification

The following documentation is required to get an ISI certification:

• Main Application Form V

Process of ISI / BIS Certification

There are two approaches for Indian manufacturers to become certified with the ISI Mark:

• Regular Procedure
• Simplified Procedure 

Regular Procedure

With the possible exception of cases deemed "All India first," which might take up to 180 days, the licensing procedure is expected to be finished in 120 days. This timeline starts on the day the application is received, assuming that at different points in time the documentation, unit assessment, and product conformance are all deemed acceptable.

Step 1: Manufacturing Unit Customization in Compliance with Applicable Indian Standards

• Identifying the applicable Indian Standard
• Establishing in-house testing facilities as per the Standard's requirements

Step 2: Submission of the Application Form

• Preparing an Internal Test Report for the product by the relevant Indian Standard
• Compiling all necessary documents
• Completing the Online Application Form
• Online payment of application fees directly to BIS
• Submitting hard copies of the Application Form with all enclosures to the relevant Branch Office (BO) of BIS

Simplified Procedure

This is a much faster process than the standard procedure. After a factory inspection is deemed satisfactory and the initial evaluation establishes that the sample complies with the applicable Indian Standard(s), the license application process is expected to be finished in 30 days.

Step 1: Adapting the Manufacturing Unit to Comply with the Relevant Indian Standard

• Identifying the applicable Indian Standard
• Establishing in-house testing facilities to meet the Standard's requirements

Step 2: Sample Testing

• Obtaining the necessary certificate for raw materials (Material Test Certificate - MTC)
• Conducting product sample testing at a BIS-recognized testing laboratory

ISI Mark Certification Process for Foreign Manufacturers

The process of obtaining ISI Mark Certification for Foreign Manufacturers typically includes the following steps:

Step 1: Application

• Compile all the required documents.
• Submit the documents along with the Application Fee.
• An Application Number will be allotted.
• Scrutiny of the Application will be conducted within a specified time frame.​

Step 2: Query Raised (If Any)

• If any documents are missing or there is non-compliance, you will be informed.
• You need to submit a reply within the given timeframe.
