bump test kit(s) to permit periodic testing your gas detector alarms in addition to your cause and effects. Bump tests should be carried out in the same way as a conventional fire system, concurrently with fire drills.
Bump Test Kit
3 x calibration gas adaptors
1 x flow valve
1 x hose
1 x 1 L water volume (12 L compressed gas) of calibration gas
1 x 1 L water volume (12 L compressed gas) of zero gas (normally nitrogen)
1 x carry case
Please note this bump test kit should only be used for bump testing Fixed CO
2, CO, Flammable and O 2 sensors.
Bump Test Gas Contents
4000 ppm Carbon Dioxide
50 ppm Carbon Monoxide
1% Methane (CH
4) (20% LEL)
Furthermore, please note that bump testing is only testing to make sure the detector is reaching its alarm levels, responding to gas, and working correctly, it is not a full calibration or service.
IGD provides technical calibration kits for use by trained IGD Engineers to carry out a full system calibration. Every 6 months the system must be calibrated by a trained IGD engineer. IGD provides a flexible service contract to best suit your requirements.
The bottles provided are 1 L water volume cylinders usually containing 12 L compressed gas for 6 or more tests. Each kit is supplied with a bottle of bump test gas and zero gas, usually pure nitrogen. Kits are supplied with a full set of IGD detector bump gas adaptors, flow valve and hose. In addition, the set is also supplied in a storage carry case.
