ISO 7076-6:2024

Overview

ISO 7076-6:2024 establishes internationally recognized requirements for vehicle-mounted compressed air foam systems (CAFS) used in fire protection. Designed to ensure consistent safety, performance, and operational efficiency, this standard is applicable to CAFS permanently installed, transportable, or mobile within fire-fighting vehicles. The systems addressed by ISO 7076-6:2024 operate effectively within ambient temperatures ranging from –10 °C to +40 °C. The standard focuses on safeguarding personnel, enhancing fire suppression capabilities, and supporting the reliable operation of CAFS in emergency situations.

By providing clear requirements for design, installation, operation, and maintenance, ISO 7076-6:2024 supports manufacturers, fire departments, and regulatory authorities in ensuring the safe and effective deployment of foam extinguishing systems in mobile fire-fighting applications.

Key Topics

• Scope and Applicability:

  • Requirements for CAFS integrated into or used with fire-fighting vehicles
  • Ambient operation temperature of –10 °C to +40 °C
  • Does not apply to stationary CAFS

• System Design and Safety:

  • Mechanical and electrical safety measures in line with ISO and IEC standards
  • Prevention of over-pressurization and protection against overheating and over-speed
  • Safeguarding personnel from moving and hot parts

• Performance and Operation:

  • Criteria for proportioning ratio and foam solution/air volume ratios
  • Provisions for continuous delivery of compressed air foam during operation
  • Performance endurance requirements, including uninterrupted six-hour operation

• Testing and Assessment:

  • Defined procedures for visual inspection, engineering assessment, and testing
  • Conformance assessments for type and individual CAFS models
  • Measurement and verification of delivery rates, pressure, and system marking

• Marking and User Instructions:

  • Durable marking for identification and operational guidance
  • Short-form operating instructions and data provided at operator’s panel
  • Clear instructions for maintenance, servicing, and troubleshooting

Applications

Vehicle-mounted compressed air foam systems specified in ISO 7076-6:2024 serve a broad range of fire-fighting applications, including:

• Municipal and Industrial Fire Services: CAFS-equipped fire engines and response units benefit from faster, more effective fire suppression, especially in areas with challenging topography or infrastructure.

• Rural and Wildland Firefighting: Enhanced foam coverage and adhesion make these systems ideal for combating wildfires and agricultural fires.

• Emergency Response: Mobile foam systems can be quickly deployed to fire incidents at chemical plants, storage facilities, and transportation accidents, supporting rapid intervention and minimizing property damage.

• Specialized Rescue Vehicles: Transportable or mobile CAFS can be mounted on a variety of emergency vehicles, including those operating in remote or hazardous environments.

Organizations adhering to ISO 7076-6:2024 can help ensure higher levels of personnel safety, system longevity, and reliable fire suppression performance in demanding, real-world conditions.
