Similar International Standards
BS 336:2010British Standards Institution (BSI), UK
HighCurrent
Fire brigade and industrial fire-fighting equipment. Fire hose couplings and ancillary equipment
Covers design, materials, and testing for fire brigade branchpipes, nozzles, and couplings.
EN 15182-3:2007+A1:2009European Committee for Standardization (CEN), Europe
HighCurrent
Portable equipment for use with fire-fighting and rescue service vehicles - Fire-fighting hoses nozzles - Part 3: Smooth bore nozzles PN 16
Specifies requirements for smooth bore nozzles, a key component of the extended branch pipe assembly.
NFPA 1964:2023National Fire Protection Association (NFPA), USA
MediumCurrent
Standard for Spray Nozzles
Focuses on performance criteria for handline nozzles, including flow, pressure, and durability.
Key Differences
≠IS 11101 is highly prescriptive, defining a specific 900 mm long assembly, whereas international standards like NFPA 1964 and EN 15182 are more performance-based, allowing for design variation as long as performance criteria (flow, reach, handling) are met.
≠The mandated inlet connection in IS 11101 is the 63 mm Instantaneous coupling (as per IS 903), which is not compatible with international systems that use Storz (EN), BS 336 Instantaneous (UK), or NH threads (NFPA).
≠International standards like NFPA 1964 specify rigorous performance tests, including flow rate measurements at various pressures, durability/drop tests, and spray pattern evaluations, which are not required by IS 11101.
≠Material specifications in IS 11101 are tied to specific Indian Standard grades (e.g., LTB-2, IS 617 Aluminium). Modern international standards typically define material requirements by performance (e.g., corrosion resistance, tensile strength) rather than specific alloys.
Key Similarities
≈All standards serve the same fundamental purpose: to provide firefighters with a durable, manually operated device to form and direct a jet of water for firefighting.
≈A mandatory hydrostatic pressure test is a common requirement across all standards to ensure the product's integrity and safety under pressure, with the test pressure being significantly higher than the rated working pressure.
≈All standards require the use of corrosion-resistant materials, such as bronze/gunmetal, specific aluminium alloys, or stainless steel, to ensure longevity when exposed to water and firefighting agents.
≈Permanent marking of key information, including the manufacturer's name or trademark and the standard to which the equipment conforms, is a universal requirement.
