Whether they are joined or molded, rubber tubes are essential parts of bicycle tires that greatly enhance their operation and performance. Rubber material that is liquid or semi-liquid is injected or poured into a mold during a precision molding procedure to make molded rubber tubes, which are seamless and lack seams or connections. These tubes provide bicycle tires a dependable inner structure by being consistent and long-lasting. Conversely, jointed rubber tubes are created by joining disparate rubber tubing pieces together using mechanical, vulcanization, or adhesive bonding techniques. These connections provide flexibility, enabling tailored tube lengths or combinations to accommodate a range of bicycle tire sizes or repair requirements. Cycle rubber tubes that are jointed or molded both perform crucial roles in preserving tire integrity by offering the necessary air-filled support inside the tire casing. They provide essential features including traction, stability, and shock absorption, which improve the entire riding experience and meet different tire sizes and repair needs among cyclists.
The need for cycle rubber tubes whether jointed or molded remains strong because of the cycling community's constant need for replacements, repairs, and upkeep; other factors include technological improvements and customer preferences for long-lasting, high-quality tubes.
Under IS 2415: 2005, all cycle-rubber tubes whether joined or moulded are now required to be part of the ISI Certification Scheme.
The dimensions and extra requirements for cycle rubber tubes (jointed and molded) intended for tire compatibility, as described in IS 2414, are specified in this standard.
Without the ISI Mark, this product cannot be marketed, imported, or exported into the Indian consumer market.
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.

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
Step 2: Submission of the Application Form

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
Step 2: Sample Testing
