BIS Certification for Fire Hose Delivery Couplings, Branch Pipe, Nozzles and Nozzle Spanner IS 903:2025

Fire hose delivery coupling, branch pipe, nozzle, nozzle spanner are some of the important components used in firefighting systems to control the water flow and pressure in firefighting operations. These need to be very reliable and operate under severe pressure for their effective operation under such conditions.

In order to guarantee their reliable operation in emergencies, certification under the BIS is mandatory. It ensures that such firefighting accessories comply with quality and safety specifications through assessment and testing. IS standard 903: 2025 defines the requirements for toughness of material, dimensional tolerances, pressure resistance and functional compatibility.

What is IS 903: 2025?

This is the Indian Standard for fire hose delivery couplings, branch pipes, nozzles, and nozzle spanners used in firefighting systems. It outlines the material requirements to ensure safe and efficient water delivery during emergency fire-fighting operations. As per the BIS (Bureau of Indian Standards), these fire-fighting accessories are:

Evaluated for corrosion resistance
Assessed for pressure resistance
Tested for operational reliability
Checked for proper fitment between components

Who can apply for Fire Fighting Nozzles BIS License?

BIS authorisation under IS 903: 2025 is required for businesses involved in manufacturing, importing, or supplying Fire Hose Delivery System in India.

Applicable to:

Manufacturers (India) - Must get BIS approval if the products are covered under QCO.
Foreign Manufacturers - Need certification to export the firefighting accessories to India.
Importers/Brand Owners - Must ensure that the products are BIS-certified before sale.
Sellers/Distributors - Should only sell certified Fire Hydrant Accessories.

Testing and Inspection Requirements

To ensure reliable performance of fire hose delivery couplings, branch pipes, nozzles, and nozzle spanners used in firefighting systems, the Bureau of Indian Standards outlines the minimum requirements in IS 903: 2025. This certification ensures that manufacturers produce fire-fighting accessories with proper strength, accurate dimensions, pressure resistance, and dependable operational performance for effective use during emergency fire response situations. The BIS testing parameters and quality checks for the pipes and nozzles are listed below:

Test Group	What is Tested	Purpose
Dimensional Accuracy Test	Coupling size, thread dimensions, nozzle diameter, branch pipe geometry	Ensures correct fitment and interchangeability of components
Hydraulic Pressure Test	Water pressure resistance of couplings, branch pipes, and nozzles	Ensures leak-proof performance under high-pressure firefighting conditions
Leakage Test	Joint sealing, assembly points, and fitted connections	Ensures no water leakage during operational use
Flow Performance Test	Water discharge rate through branch pipes and nozzles	Ensures effective and controlled water delivery during firefighting
Deflection Test	Structural bending under load conditions (nozzle spanner/assembly)	Ensures mechanical stability under operational stress
Corrosion Resistance Test	Exposure to humidity, salt spray, and environmental conditions	Ensures protection against rust and long-term degradation
Thread Compatibility Test	Thread engagement and matching with standard fire hose fittings	Ensures proper connectivity with firefighting systems
Strength & Load Test	Mechanical strength of couplings, spanners, and joints	Ensures durability under repeated use and physical stress
Assembly Fit Test	Alignment of coupling, branch pipe, nozzle connection points	Ensures secure and proper assembly without mismatch
Anti-Corrosive Treatment Check	Surface coating and protective treatment verification	Ensures extended service life in harsh environments

Steps for Fire Safety Equipment BIS License

The BIS Authorisation process ensures that the fire nozzle and branch pipe 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 chemical composition, silica content, moisture content, fineness, compressive strength, and other physical performance parameters.
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

After the manufacturer obtains a BIS license, the ISI Mark for Firefighting Hose Fittings must be written clearly and permanently either on its packaging or on the product. The marking should also include key information, such as the manufacturer’s identification and licence number (CM/L). This ensures the product complies with all safety parameters. Additional details are mentioned below:

Requirement	Details
ISI Mark	Indicates that the product is BIS certified and conforms to standards
Standard Number	IS 903: 2025
CML Number	Certification Marks License (CML) number issued by BIS
Manufacturer Details	Name of manufacturer or registered trademark
Batch / Date	Batch number, heat number, or manufacturing date for traceability

Note: Marking is typically applied using durable stamping, tagging, or permanent printing to ensure clear identification during handling, storage, and transportation, as per BIS marking requirements.
