BIS Certification for Tubes of Pneumatic Tyres: Know the Process

Any industry or process without a system can be a chaotic mess. The presence of standards ensures that whatever the manufacturer produces is of the highest quality. The standard helps avert process shortcomings that adversely impact product quality. An institution like the Bureau of Indian Standards is reining how end-users products are being processed, produced, and tested. They provide an explicit framework through different standards for a variety of products. BIS also runs a Compulsory Registration Scheme that covers various end-user products. Registration under this scheme is mandatory for eligible manufacturers. In this article, we shall talk about the process concerning the BIS certification for tubes of pneumatic tyres.

Highlighting the Role Of IS 13098:2012- An Indian Standard for Tubes for Pneumatic Tyres

A product like Tubes for pneumatic tyres also falls CRS scheme and their quality and testing aspects are governed by the Indian standard called IS13098:2012. The said standard came into effect after it was adopted by BIS on the recommendation of the Transport Engineering Division Council. The draft of the standard was prepared by the Automotive Tyres, Tubes, and Rims Sectional Committee. It is this standard which lays down the foundation for BIS certification for tubes of pneumatic tyres.

The standard pens down the requirements concerning pneumatic tyre tubes representing the vehicle category namely- L1, L2, L5, M, N, and T.

The standard mandates the affixing of a Standard Mark or ISI mark on each tube, but it is only possible when the manufacturer has the permit to do so.  BIS grants such a permit against a prescribed application and after performing an extensive inspection process.

Notable Norms under the IS 13098:2012

The inner tube refers to a flexible tube installed within a casing- a tire. It can get burst whenever the pressure inside it surpasses the workable limit. It is usually inflated by compressed air. The tube is designed to keep the tire optimally inflated even under rigorous driving conditions.

The sourcing material for tube manufacturing should be none other than an apt rubber compound. It must possess an endless annular ring shape and a spud or valve conforming to IS 9081.

The Standard Classifies The Tube Into Two Categories:

  1. Class A: Halo-butyl rubber/Butyl IS rubber, and its derivatives and blends
  2. Class B: Natural rubber and its derivatives and blends

Each tube possessing a valve should be inflated by the compressed air and undergo a water leakage test. Their surface area must have a thicker thread so their contact with the casing stay intact no matter the road or driving conditions.

Tests Recommended For the BIS Certification for Tubes of Pneumatic Tyres

The Bureau of Indian Standards takes the following tests into account as the ground for certificate facilitation. All these tests are cited in the IS 13098:2012.

  • Thickness Test
  • Elongation Test
  • Aging Test
  • Strength Of Splice
  • Air Tightness Test

What Are The Labelling And Marking Norms For Tubes?

Labelling and marking norms are cited under IS 13098:2012. Each tube should reflect the mandatory ISI marking. However, its applicability will depend on whether or not you qualify for the BIS registration.

Before granting the certificate, the BIS undergoes a rigorous vetting procedure to ascertain the compliance level in accordance with the Indian Standard.

As with other registration applications, the BIS registration application is filed along with some mandatory paperwork as shown below:

  • Business registration
  • Factory license
  • Pollution NOC
  • Fire NOC
  • Specimen Testing report granted by a certified lab
  • Lab details, including available resources

Process of Securing BIS Certification for Tubes of Pneumatic Tyres

The process to apply for BIS certification for tubes of pneumatic tires is as follow:

Step 1: File the BIS Registration Application

First, you need to visit the BIS web portal and fill out the online application. The e-form will prompt you to enter various details concerning business, production capabilities, testing facility, product, and so on. Once done, upload the documents (as discussed shortly) and pay the application fee.

Step 2: Inspection of Dossiers and Production Premise

In this step, the authority (BIS) will inspect the application and paperwork for any shortcomings, which will be shared with the application for correction. An ample timeline shall be granted to the applicant to fix the concern(s) raised by the authority.

Document vetting will be followed by the premise inspection in which the officials shall vet the production facility for any non-compliance. Lastly, the inspector will pick some samples/specimens (for which a license is required) in the prescribed quantity or number for lab testing.

Step 3: Lab Testing Of Sample(S) and Report Preparation

The selection samples will then be shared with the certified lab for performance evaluation. As cited earlier, these samples will be subjected to the following tests.

  • Thickness test
  • Elongation test
  • Aging test
  • Strength of splice
  • Air tightness test

The successful completion of these tests leads to the next step, which is report generation. The lab will prepare a detailed report reflecting the performance level of the sample against each test.

Step 4: Report Inspection and Grant of Certificate

The authority i.e BIS[1] will inspect the lab report to underline any concern regarding the product performance. If the report comes out clean, the authority shall grant the BIS certification for tubes of pneumatic tyres to the applicant.


BIS Certification for tubes of pneumatic tyres is an approval that you will require to affix the ISI marking on the product (s). The non-availability of this registration can attract severe penalties for defaulters. So, it’s prudent to timely secure the same to avert such mishaps.
