IS 14933:2001 is the Indian Standard (BIS) for high-pressure fire fighting hose -specification. This standard specifies the requirements for high-pressure fire fighting delivery hoses, commonly used with fire tenders and in high-rise building systems. It covers the material, construction, dimensions, and performance characteristics like proof and bursting pressure for two distinct types of hoses.

Standard on Fire Hose
Covers various fire hoses, but focuses on collapsible lay-flat types, not the semi-rigid hose specified in IS 14933.
Key Differences
≠IS 14933 specifies a high-pressure 'Type B' hose with a 4.2 MPa maximum working pressure, a category not present in EN 694, which focuses on lower-pressure systems (max 1.2 MPa).
≠EN 694 mandates an ozone resistance test for the outer cover to prevent environmental degradation and cracking, a specific requirement not included in IS 14933:2001.
≠The minimum adhesion strength between the lining, reinforcement, and cover is specified as 1.5 N/mm (1.5 kN/m) in EN 694, which is 50% higher than the 1.0 kN/m required by IS 14933.
≠The safety factor (ratio of burst pressure to working pressure) for the standard hose type is higher in EN 694 (4:1) compared to IS 14933 Type A (approx. 2.9:1).
Key Similarities
≈Both IS 14933 and its primary equivalent, EN 694, are specifically developed for semi-rigid fire hoses intended for first-aid firefighting from fixed hose reel systems.
≈The fundamental construction specified is analogous, requiring an inner elastomeric or plastic lining, a textile reinforcement layer, and a weather- and abrasion-resistant outer cover.
≈Core performance tests are shared, including hydrostatic proof pressure, burst pressure, and kink resistance tests to ensure operational reliability and safety.
≈Both standards cover the common nominal bore sizes of 19 mm and 25 mm, which are standard for hose reel applications globally.

What is the difference between Type 1 and Type 2 hose?+
Type 2 has higher pressure ratings (3.0 MPa proof, 5.0 MPa burst) compared to Type 1 (2.1 MPa proof, 3.5 MPa burst) and is designed for more demanding applications. (Table 2)
What are the standard internal diameters available?+
The standard specifies nominal bore diameters of 38, 50, 63, and 70 mm. (Table 1)
What markings should be present on the hose?+
The hose must be marked with the manufacturer's name/trademark, nominal bore size, type (1 or 2), the words 'IS 14933', and the year of manufacture. (Clause 9.1)
Is this hose suitable for suction?+
No, this is a delivery hose designed for positive pressure only. Suction hoses are covered by different standards like IS 3549.
