About this file
This document is a detailed specification for 1" to 5" attack fire hoses, which appears to be part of a procurement opportunity for fire departments or emergency services. The specification covers three hose size ranges (1" to 3", 2.5", and 4" to 5"), providing comprehensive technical requirements for heavy-duty double jacket fire hoses designed for front-line firefighting. Each hose size range includes specific technical specifications such as construction materials (high tenacity filament polyester yarn), performance standards, lining requirements, and technical charts detailing weight, service pressure, proof pressure, burst pressure, and coupling specifications.
The hoses are designed to meet rigorous performance standards, including resistance to chemicals, UV rays, and extreme temperatures, with a flexible design that can withstand temperatures as low as -65 degrees Fahrenheit. The specifications require compliance with NFPA 1961, Underwriter's Laboratories, and Factor Mutual standards, and offer optional Permatek treatment for improved abrasion resistance and visibility. The technical charts provide detailed performance metrics for each hose size, with service pressures ranging from 300-400 PSI, proof pressures from 600-800 PSI, and burst pressures from 900-1200 PSI, indicating robust engineering for demanding firefighting environments.

ATTACHMENT B
1” to 3” ATTACK HOSE SPECIFICATION:
Scope:
• Hose manufactured to this specification shall be of superior quality and workmanship. This heavy-duty double jacket fire hose shall be designed to withstand the rough usage of front line firefighting.
Construction and Features:
• The hose shall be of double jacket construction.
• The inner jacket shall be made with high tenacity filament polyester yarn in both the warp and weft directions, to provide maximum strength.
• The outer jacket shall be made with virgin spun polyester warp yarn and a filament polyester weft yarn. Hose made using nylon or other materials shall not be considered as meeting this specification.
• The hose outer jacket shall have a minimum filler yarn of 10.0 per inch (394 per meter)
• The hose shall be available in any of eight colors listed with our Permatek treatment, upon request.
• The hose shall be resistant to most chemicals and petrol products, rot & mildew, hydrolysis, and resist deterioration due to exposure to UV rays and ozone.
• The hose must be of sufficient body and weight to meet the demands of heavy-duty firefighting.
Performance:
• The hose, in all sizes, shall have minimum service, test, and burst pressures as specified in the technical chart listed below. Hose which do not meet these minimum pressures shall not be considered as meeting this specification.
• The hose shall have a maximum flow with minimum friction loss.
• The hose jacket shall be highly abrasion resistant.
• There shall be no defects, dirt, knots, lumps, or other irregularities affecting the performance of the hose.
• The hose must resist kinking and remain flexible to -65 degrees Fahrenheit
(-55 degrees Celsius)
Lining:
• The hose lining shall have excellent resistance to most chemicals, petrol products, ozone and UV
• The hose lining shall be capable of being approved for potable water, when so ordered.
• The thermoplastic lining material used for this specification shall have a flawless record in the fire hose industry.
• The hose jacket shall be lined by the patented Mertex method. The lining material in its molten state shall fill the corrugations of the weave fusing to every wrap and filler thread and provide a very smooth and low friction waterway. No adhesive or backing material shall be used to bond the lining and it shall yield maximum flow with minimum friction loss. A hose manufactured by inverting an exterior coated hose shall not be considered as meeting this specification. Hose manufactured with the use of adhesives or backing for bonding the liner, or hose made with rubber liners shall not be considered as meeting this specification.
Treatment:
• When requested, the exterior jacket shall be Permatek treated for greater abrasion resistance, improved visibility, and reduced moisture pick-up.
Standards:
• Fire hose manufactured to this specification shall meet and exceed all performance requirements of NFPA 1961, Underwriter’s Laboratories and Factor Mutual.
• The hose shall be ULC approved and can be labeled upon request in the sizes specified.
