BIS Certification for Aluminium Alloy Tubes for Irrigation Purposes-Welded Tubes IS 7092 (Part 1):1992

Aluminum alloy tubes are widely used in modern irrigation systems due to their lightweight structure, corrosion resistance, and long service life. To maintain uniform quality and safety standards, the Bureau of Indian Standards (BIS) has introduced specific guidelines under IS 7092 (Part 1): 1992.

 This standard governs the production and quality of welded aluminium alloy tubes used in irrigation systems across India.

Compliance with BIS for Aluminium Alloy Tubes for Irrigation Purposes (Welded Tubes) is not just a quality measure but a regulatory requirement under the applicable Quality Control Orders. Manufacturers must obtain BIS Certification to legally sell or distribute these products in the Indian market.

Overview of IS 7092 (Part 1): 1992

The Indian Standard IS 7092 (Part 1): 1992 specifies the technical requirements for welded aluminium alloy tubes used in irrigation applications such as sprinkler systems and water transportation. These tubes are preferred in agriculture due to their efficiency, ease of handling, and resistance to environmental conditions.

The standard covers: 

  • Chemical composition of aluminium alloys
  • Mechanical properties such as tensile strength
  • Dimensional tolerances and wall thickness
  • Workmanship and finish
  • Hydrostatic pressure and leakage requirements

Compliance with these parameters is essential for obtaining ISI Certification for Aluminium Alloy Tubes for Irrigation Purposes (Welded Tubes) and ensuring long-term performance.

BIS Certification Process for Aluminium Alloy Tubes for Irrigation Purposes (Welded Tubes)

The BIS certification process involves multiple regulatory and technical steps to ensure that Aluminium Alloy Tubes for Irrigation Purposes (Welded Tubes) comply with the applicable Indian Standard and quality requirements:

Online Registration (Manak Portal) :

Manufacturers must register on the BIS Manak Portal and submit the application online. The application includes company details, product specifications, and supporting documents. For foreign manufacturers, a hard copy of the application along with required documents must also be submitted to BIS.

Testing at BIS-Recognized Laboratory :

Product samples of Aluminium Alloy Tubes for Irrigation Purposes (Welded Tubes) are tested in a BIS-recognized laboratory as per IS 7092 (Part 1): 1992 to verify compliance with mechanical strength, dimensional accuracy, and performance requirements. For foreign manufacturers, pre-testing is conducted to ensure conformity with Indian Standards before submission.

Application Submission:

The manufacturer submits the application along with test reports, technical documents, and KYC details to BIS. For foreign manufacturers, a nomination process is completed, and an official communication is shared regarding further inspection procedures.

Factory Inspection:

BIS officials conduct an inspection of the manufacturing unit to verify:

  • Manufacturing process
  • Raw material details
  • Factory layout
  • In-house testing facilities
  • Quality control measures

Grant of BIS License:

After successful verification of documents, test reports, and inspection, BIS grants the license. For foreign manufacturers, the confidential test report is first submitted to the Foreign Manufacturers Certification Department (FMCD), and after due verification, the BIS license is issued.

Use of CML Number:

Once the license is granted, a unique CML (Certification Marks License) number is issued. The manufacturer must mark the product with the ISI Mark along with the CML number to indicate compliance.

  • Compliance with all specifications under IS 7092 (Part 1): 1992

Foreign manufacturers must appoint an Authorized Indian Representative (AIR) to apply for BIS Registration for Aluminium Alloy Tubes for Irrigation Purposes (Welded Tubes).

Marking Requirements & License Validity: IS 7092 (Part 1) 

For Aluminium Alloy Welded Tubes (Irrigation), marking and validity follow strict protocols to ensure field safety and regulatory compliance.

Marking Requirements

Once certified, the ISI Mark must be clearly and indelibly applied to each tube. The marking ensures the product meets the pressure and material standards of IS 7092 (Part 1): 1992.

Mandatory Marking Elements: 

  • Standard Number: IS 7092 (Part 1)
  • ISI Logo: The official Bureau of Indian Standards mark.
  • CM/L Number: The unique 7 or 8-digit license number.
  • Manufacturer’s ID: Name or registered trademark.
  • Technical Specs: Tube size (outer diameter and wall thickness) and alloy designation.
  • Traceability: Batch or lot number and date of manufacture.

Note: Marking is typically done via embossing or high-contrast inkjet printing at regular intervals along the length of the tube.

Validity of BIS License
