BIS Certification for Rubber Hoses for Compressed Air IS 446: 2025

Rubber Hoses for Compressed Air are used to supply air to tools, machines and industrial equipment in pneumatic systems. These are made with reinforcement layers which help in internal pressures and also give flexibility during normal movement and operation. These hoses find extensive usage in workshops, manufacturing units and maintenance workshops where continuous airflow helps in improving efficiency and productivity.

For product certification, lab testing is done as per IS 446: 2025. This test involves evaluation of physical dimensions, bursting strength tests, and adhesion of rubber as well as textile layers. The test procedure also involves the evaluation of flexibility, elongation, and mechanical resistance of the products.

What is IS 446: 2025?

This is the Indian Standard for rubber hoses, textile-reinforced for compressed air. It mentions requirements for materials, construction, dimensions, workmanship, and performance to ensure safe and reliable use of hoses. As per the BIS (Bureau of Indian Standards), these hoses are:

Verified for material quality
Assessed for reinforcement strength
Evaluated for pressure resistance
Tested for durability and performance

Who is Eligible for Rubber Air Hose BIS Approval?

BIS authorisation under IS 446: 2025 is required for businesses involved in manufacturing, importing, or supplying industrial rubber hose in India.

Applicable to:

Manufacturers (India) - Must get BIS approval if the air hoses are covered under QCO.
Foreign Manufacturers - Need certification to export the product to India.
Importers/Brand Owners - Must ensure that the products are BIS-certified before sale.
Sellers/Distributors - Should only sell certified textile-reinforced compressed air hoses.

Testing and Inspection Requirements

To ensure safe and efficient delivery of compressed air in industrial applications, the Bureau of Indian Standards outlines the minimum requirements under IS 446: 2025. This certification ensures that manufacturers produce rubber hoses with proper reinforcement, pressure resistance and long-term durability for safe usage. The BIS testing parameters and quality checks for the Rubber Hoses are listed below:

Test Group	What is Tested	Purpose
Construction Test	Hose construction, reinforcement pattern, layers of rubber and textile reinforcement	Ensures correct structural design and conformity to IS 446: 2025
Dimensional Test	Internal diameter, outer diameter, wall thickness, and length tolerances	Ensures dimensional accuracy and interchangeability of hoses
Proof Pressure Test	Hose ability to withstand specified internal pressure without leakage or deformation	Ensures safety under operating pressure conditions
Burst Pressure Test	Maximum pressure at which hose fails or ruptures	Ensures safety margin and pressure endurance capability
Change in Length Test	Variation in hose length under working pressure	Ensures stability and controlled expansion during use
Adhesion Test	Bond strength between rubber layers and textile reinforcement	Ensures structural integrity of hose layers
Flexibility Test	Hose flexibility at specified temperature conditions	Ensures ease of handling and operational flexibility
Tensile Strength & Elongation Test	Strength and stretchability of rubber compound	Ensures mechanical strength and durability of material
Ageing Resistance Test	Changes in physical properties after heat/aging exposure	Ensures long-term durability and resistance to environmental effects
Ozone Resistance Test	Resistance of rubber to ozone exposure	Ensures protection against cracking and environmental degradation
Dimensional Inspection (In-process)	Continuous measurement during manufacturing	Ensures ongoing production consistency

How to get BIS License for Compressed Air Rubber Hoses?

The BIS Authorisation process ensures that the pneumatic rubber hoses meet the required standards for efficient operation. This process is set by the Bureau of Indian Standards (BIS) and includes the following steps:

Online Registration: Manufacturers register on the BIS Manak portal by submitting company, factory, and product details. Foreign manufacturers must appoint an Authorized Indian Representative (AIR).
Testing at BIS-Approved Laboratory: Product samples are tested in BIS-approved laboratories for physical properties, moisture content, chemical characteristics, dimensional stability, and overall material performance.
Application Submission: The application is submitted along with test reports, technical documents, and factory details. Foreign manufacturers must also submit AIR-related documents.
Factory Inspection: The Bureau of Indian Standards officials inspect the manufacturing units to verify the production process, safety measures, and quality control system.
Grant of BIS License: Upon successful verification of all requirements, BIS grants the certification license under Scheme-I.
Use of ISI Mark: Once approved, the manufacturer can use the ISI mark on the product with a CM/L number, confirming that the product meets BIS standards.
