The cable samples are placed vertically next to one another on a

for the pre-arranged times.

After burning, the samples are wiped clean to examine for char (the crumbling) of the cable surface. The charring should not have reached a height exceeding 2.5m above the bottom edge of the burner.

MAX-FOH cables meet the requirement of IEC 60332 part 3

IEC 60754 – Acid Gas Emission Test

IEC 60331 – Fire Test

Due to the concern regarding the amount of acid gas which could be produced when cables are burnt, this international test was developed to determine the amount of gas evolved by burning cables.

The recommended values of the test state that the weighted pH value should not be less than 4.3, when related to 1 litre of water. The weighted valued of conductivity should not exceed 10us/mm.

MAX-FOH cables meet the above requirements.

The international fire test is designed to establish whether a cable can maintain circuit integrity during and after exposure to fire.

A sample of cable is exposed to fire for 90 minutes at a temperature of between 750°C and 800°C, after 90 minutes the fire is extinguished and the current is turned off. After a further 12 hours, the sample of cable is re-energized and must maintain its circuit integrity.

MAX-FOH cables meet the requirements of IEC 60331

Additional Considerations

As well as requirements written into international and British cable standards, there are other essentialcriteria which designers and consultants need to consider – is the cable able to withstand voltage spikes, transmit date and prevent flame propagation?

All MAX-FOH cables do comply with these additional benefits, including the added advantage thatMAX-FOH requires fewer joints in a cable run compare to mineral, reducing the risk of weak links in thechain. MAX-FOH does not require complicated terminations and is therefore quicker and easier to install.

This test defines the ability of bunched cables to restrict vertical flame propagation when laid in trunking, cable trays or conduit. The test comprises of 3 categories each determined by the amount of combustible material in a 1 metre sample, as shown in the table below.
