EN 61034 Common test methods for cables under fire conditions: Measurement of smoke density of cables burning under defined conditions


The 3 Metre Cube is used for measuring smoke emission when electric cables are burned under defined conditions, for example, a few cables burned horizontally.These units are produced to meet the specification used in many electric cable tests.The unit can be supplied in a self-assembly kit form or can be fully installed by FTT Engineers.


The equipment comprises of: ■


3 Metre Cube assembly ■


Photometric system, stands, fans and sample mounting frames


■ Extraction fan and ducting ■ Chart Recorder or Windows Software.


EN 50267-2-3 Common test methods for cables under fire conditions:Tests on gases evolved during combustion of materials from cables


Part 2-3: Determination of degree of acidity of gases for cables by determination of the weighted average of pH and conductivity


This test was developed to assess the amount of acid gas which is evolved when cable insulating, sheathing and other materials burn as this acid can cause damage to electrical and electronic equipment not involved in the fire itself..This test method uses pH and electrical conductivity as an indirect assessment of this property and is being used as the assessment method for the additional acid classification with classes B1ca


,B2ca


The equipment comprises of: ■


Control unit ■ Furnace ■ Magnetic stirrer ■ pH meter and calibration pH solutions ,Cca and Dca
