IS 12492: 1988

It is difficult to survive in this competitive market without a standard quality and certified product. BIS licenses may also be required in order to use the standard ISI Mark and sell products in India.

To obtain BIS certification and produce a high-quality product, the manufacturer must ensure that their product meets the Indian standard.

Let's take a closer look at IS 12492:1988 for Thermoplastics Hoses (Textile Reinforced) for Compressed Air.

Thermoplastic Hoses (Textile Reinforced) for Compressed Air are covered by IS 12492:1988. The Bureau of Indian Standards adopted this Indian Standard on November 9, 1988, after the Petroleum, Coal, and Related Products Division Council approved the draft finalized by the Rubber Products Sectional Committee. Because of the increased manufacture and use of thermoplastic hoses in developed countries, they are also being used in India; as a result, some manufacturers have begun producing them. Rubber and plastic houses have comparative advantages and disadvantages depending on the application. Considering these changes and developments, BIS formulated a standard for thermoplastic hoses.

This standard specifies the requirements, sampling methods, and testing procedures for thermoplastic hoses with textile reinforcement suitable for working pressures up to 1.4 MPa and application temperatures ranging from - 10 to + 55°C.

This standard covers the three types of hoses listed below:

  1. Type 1 - industrial air hoses with a maximum working pressure of 0.7 MPa,
  2. Type 2 - industrial air hoses with a maximum working pressure of 1.0 MPa, and
  3. Type 3 - air hose for heavy-duty mining and construction work with a maximum pressure of 1.4 MPa.

Tolerances and dimensions of hoses shall be as per the prescribed standard. Hoses must adhere to the standard's physical and performance specifications. The hose's colour (transparency), opacity, and other physical characteristics must all be consistent.

A BIS license for Thermoplastic Hoses (Textile Reinforced) for Compressed Air is granted to use the standard mark as per IS 12492:1988. It is required to maintain an adequately staffed and resourced laboratory to conduct the various tests outlined in the standard. The test shall be conducted as per the method specified in the standard.


Each length of the hose must be marked with the manufacturer's name or trade-mark, the IS number, the hose type, the nominal bore size, the design working pressure, and the quarter and year of manufacture. The above markings should be made at approximately 10-metre intervals for long lengths. Standard ISI Marks may also be applied to each length of the hose.

To use a standard mark, the manufacturer must first obtain a BIS license from the Bureau of Indian Standards for Thermoplastics Hoses (Textile Reinforced) for Compressed Air. The Bureau grants a BIS licence based on a successful assessment of the manufacturing infrastructure, quality control and testing capabilities, and manufacturing process. To ensure that the product meets the requirements of applicable Indian standards, BIS certification for Thermoplastics Hoses (Textile Reinforced) is required. BIS certification helps manufacturers gain consumer trust and continue to export and sell their products in the Indian market.
