ISI / BIS Certification for Flux Cored Solder Wire

Flux-cored solder wire is a specialized soldering material designed for joining metals in various applications. Unlike traditional solid wire solder, it contains a core of flux, a chemical compound that plays a crucial role during the soldering process. Flux serves multiple functions, including cleaning the metal surfaces being soldered, protecting them from oxidation, aiding in heat distribution and reducing the surface tension of the solder for improved flow. This makes flux-cored solder wire particularly effective at creating strong and reliable solder joints. It finds widespread use in electronics for soldering components on printed circuit boards, in plumbing for joining copper pipes and in various other industries where precise and clean soldering is required.The IS Standard IS 1921:2005 for flux cored solder wire plays a crucial role in ensuring the quality, safety and reliability of soldering processes and products for manufacturers. IS 1921:2005 defines specific requirements for flux cored solder wire, including its composition, mechanical properties and performance characteristics. Manufacturers adhering to this standard can produce solder wire with consistent quality, minimizing defects and variations. IS 1921:2005 includes safety guidelines and requirements, helping manufacturers create a safe working environment for their employees and ensuring that soldering operations meet safety standards. Manufacturers that comply with IS 1921:2005 can meet these regulatory obligations, avoiding potential legal issues and fines.

Note: Manufacturers of flux cored solder wire are obligated to obtain the mandatory ISI Certificate.

ISI Certification is an essential measure to ensure that these soldering materials conform to rigorous technical standards, safety regulations and quality criteria, ultimately contributing to the reliability and performance of soldered connections in diverse applications. It provides assurance to industries such as electronics manufacturing, automotive assembly and industrial fabrication that the flux cored solder wire they use in their soldering processes is of the highest quality, ensuring the integrity and durability of soldered connections.

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)
