Model appraisal

Tests are carried out on the construction, function, performance and other factors of a particular model based on predetermined technical standards, and the model is certified as conforming to technical standards.

Lot approval

Testing is carried out to determine whether or not individual units of fire equipment conform to the construction, material, performance and other factors of the certified model. Products that pass a lot appraisal have an approval mark attached.

However, for special pump vehicles and special fire extinguishing equipment for fire vehicles, each individual unit is evaluated as to whether or not it conforms to construction, material, performance and other factors.

Appraisal and approval of fire extinguishing devices

Perform appraisal of fire extinguishing devices and tools in fire extinguishing equipment to determine whether they meet technical standards, and then indicate JFEII approval on said devices and equipment.

Items showing JFEII approval do not need individual inspection during fire extinguishing inspections at time of installation to confirm performance.

Items approved

  • Automatic fire alarm equipment area alarm devices
  • Emergency bells and automatic sirens for emergency alarm equipment
  • Emergency public address systems for emergency alarm equipment
  • Central control panel
  • Package type automatic fire extinguishing systems

Model approved

Give approval to models that meet technical standards.

Performance appraisal on new technical products

On request, fire prevention equipment with outstanding performance due to new technology, but without technical regulations or standards, can be evaluated as to whether or not it is superior in performance.
The evaluation is carried out by the Technical Appraisal Board of experts for special fire equipment.

Fire equipment approved by the evaluation are indicated as such. Currently, evaluations are carried out for the following equipments:

  • Fixed type fire extinguishing devices
    (Fixed fire extinguishers, Impulse fire extinguishing guns, sprinkler heads for fire detection use)
  • Alarm devices (Detector lifters, etc.)
  • Mechanical escape devices (Descending devices, descending lifts)
  • Fire pumps (High pressure pumps)
