This aim will be achieved by: Record the extent of damage. These test methods only evaluates the ignitability of bedding products and does not evaluate the burning behavior of a specific item.

Why test according to this standard?

  DEMYSTIFYING THE CALIPHATE PDF

The purpose of this European Standard is to ensure that the necessary essential safety requirements according to Annex I of the Pressure Equipment Directive are fulfilled in order to guarantee the safety of water tube boilers.

Light the propane emerging from the burner tube, adjust the gas flow to the rate and allow the flow to stabilize for at least s. Water-tube boilers and auxiliary installations – Part 1: If flaming ignition of the test specimen is not observed, repeat the test at a fresh position.

It is also not allowed to have any occurrence of flames initiated by the smouldering cigarette. If progressive smouldering or flaming ignition of the test specimen is observed, extinguish the test specimen, note the time the test was stopped and the reason, record that ignition had occurred and discontinue testing. The requirements of this European Standard take account of pressure-related hazards, which apply to water tube boilers, including failure of pressure-retaining components due to overheating.
