: BIS Certification for Rubber Hoses, Textile-Reinforced, for General-Purpose Water Applications IS 444: 2025

Rubber Hoses find their use extensively wherever there is a need for a controlled and sustained supply of water in household, agricultural and other industrial uses. These hoses have been designed with reinforced textile coverings to ensure structural stability, pressure handling, and avoidance of problems such as kinks, leakage or deformation during repeated use. They are easily handled and provide a continuous flow of water throughout their long operating life periods.

As per IS 444: 2025 standards, tests conducted for the certification process include several aspects about material composition, accurate dimensions, and total pressure-handling capacity of the hoses. Some of the testing procedures involved are tensile strength determination, elongation at break test, resistance to burst pressure and rubber and textile layer adherence test.

What is IS 444: 2025?

This is the Indian Standard for rubber hoses for general-purpose water applications. It mentions workmanship and performance criteria to ensure safe and efficient use of the hoses. As per the BIS (Bureau of Indian Standards), these rubber hoses are:

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

BIS Approval Eligibility for Water Rubber Hoses

BIS authorisation under IS 444: 2025 is required for businesses involved in manufacturing, importing, or supplying textile-reinforced water hose in India.

Applicable to:

Manufacturers (India) - Must get BIS approval if the water delivery rubber 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 rubber hose.

Testing and Inspection Requirements

To ensure leak-free water flow, the Bureau of Indian Standards outlines the minimum requirements for hoses under IS 444: 2025. This certification ensures that manufacturers produce Rubber Hoses (Textile-Reinforced) for General-Purpose Water Applications with suitable material composition, reinforcement strength and dimensional accuracy. The BIS testing parameters and quality checks for the hoses are listed below:

Change in Length Test	Variation in hose length under pressure	Ensures stability during pressurized water flow
Adhesion Test	Bond strength between rubber layers and reinforcement	Ensures structural integrity of hose layers
Ageing Resistance Test	Changes in physical properties after heat/aging	Ensures long-term durability and service life
Resistance to Liquids Test	Swelling or degradation when exposed to water and test liquids	Ensures material stability in water applications
Flexibility Test	Hose flexibility at 23°C	Ensures ease of handling and operational usability
Ozone Resistance Test	Resistance to ozone exposure	Ensures protection against cracking and environmental damage
Low Temperature Flexibility Test	Performance under cold conditions	Ensures usability in varying environmental temperatures
Production Monitoring Test	Continuous in-process dimensional and quality checks	Ensures consistent manufacturing quality

Textile Reinforced Water Hose BIS Approval Process

The BIS Authorisation process ensures that the general-purpose water hose meets 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.

Marking Requirements & License Validity

Marking Requirements

As soon as the BIS licence is acquired by the manufacturer, the ISI Mark for agricultural water hose must be clearly and permanently displayed on the product or its packaging. Apart from the ISI Mark, there are other important points that need to be mentioned, including manufacturer identification and licence number (CM/L). Further details are mentioned below:

Requirement	Details
ISI Mark	Indicates that the product is BIS certified and conforms to standards
Standard Number	IS 444: 2025
