Introduction

Without the needed certification for the steel plates under BIS IS 2041:2009, a Chennai local pressure vessel manufacturer experienced the stoppage of a whole project. The supplied materials were technically perfect, but they were rejected at the compliance level, thus, the company faced expensive delays. The certification is not simply a legal requirement. It is the very confirmation that the plates are able to endure pressure and low-temperature conditions safely. Steel plates certified by BIS under IS 2041:2009 are the ultimate solution to quality, regulatory and customer satisfaction issues. Bureau of Indian Standards
What is IS 2041:2009?
IS 2041:2009 is an Indian Standard that defines the requirements for steel plates used in pressure vessels operating at moderate and low temperatures. It essentially lays out the benchmarks for the material which helps industries that live off the material to use it in a safe, strong, and reliable way. ISI MARK
Key points:

- It defines the steel grades that may be used for the service at temperatures from low to moderate.
- Details the chemical composition and mechanical strength ranges.
- The steel should be a fine-grained, fully killed, and heat-treated one according to the requirement.
- The quality as per the referred standard is ensured by the tensile, bend, and impact tests that are compulsory.
- Each plate is governed by the rules of marking and traceability.
- IS 2041:2009 is the standard that ensures safety, durability, and legal compliance in the fabrication of pressure vessels.
Why is BIS Certification Mandatory
- BIS certification under IS 2041:2009 verifies that steel plates for pressure vessels meet required mechanical, chemical, and safety standards.
- It is the basic necessity for the plates to have the ability to keep up with the pressure change as well as the temperature without breaking.
- Once the certification scheme is set in place by the BIS, it will involve the full-scale testing, the inspection, and a factory audit.
- The Indian government, through the Steel and Steel Products (Quality Control) Order, has made it compulsory.
- Manufacturers licensed by the BIS alone are authorized to produce or sell such steel plates in the India market.
- Such a certification is a guarantee for consumers, it is a tool for quality assurance, and it is an enabler of safe practice in the essential industries such as the oil, gas, and power sectors.

Step-by-Step Process of BIS Certification

Step1:Documentation
- Collect documents related to company registration, factory layout, and quality control.
- Also, add a manufacturing flow chart and the list of machinery/equipment.
- Get internal test reports and product specifications prepared as per IS 2041:2009.
- Make sure that all the documents are signed, updated, and in good condition for BIS inspection.
Step2:Product Testing
- Send product samples to a BIS-recognized or NABL-accredited laboratory.
- Testing includes chemical composition, tensile, bend, and impact tests.
- Ensure test parameters match the requirements of IS 2041:2009.
- Obtain a complete and valid test report for submission with the application.
Step3:Application Submission
- Create an account on the BIS online portal and fill the application form as per the given instructions.
- Upload documents required, test reports, and fees for the transaction.
- Product details should be clear (steel plates for pressure vessels as per IS 2041:2009).
- Commit the application for initial checking and receiving acknowledgment.
Step4:Scrutiny and Inspection
- Officials from the BIS go through the documents and check if the product meets the standards.
- An on-site visit to the factory is done to evaluate production and testing methods.
- The quality assurance team, labelling, and traceability records are also reviewed by the inspectors.
- Any differences pointed out must be rectified prior to the issuance of the license.
Step5:Grant of Licence
- BIS reviews inspection and test results for final approval.
- Once satisfied, BIS issues the certification licence under Scheme-I.
- Manufacturer receives authorisation to use the ISI Standard Mark.
- Maintain compliance through regular audits and licence renewals.
Documents required for BIS Certification
