Why should you use PD CLC/TS 50612- Portable electrical apparatus?
PD CLC/TS 50612 provides you guidance on the selection, use, and maintenance of portable electrical apparatus conforming to EN 50379-1 [4] and EN 50379-2 [5] or EN 50379-3 [6] to measure combustion flue gas parameters of appliances in domestic premises burning 1st, 2nd, or 3rd family gases of the following description:
- Type A, Type B, and Type C gas-fired appliances, except those appliances where the appliance instructions, prohibit combustion sampling, and,
- All gas-fired appliances for which the appliance manufacturer has provided a purpose-designed combustion sampling point or specific sampling instructions
And to use as a diagnostic instrument to assist an operative:
- In confirming satisfactory combustion at the time of commissioning, in accordance with appliance instructions or national or local regulations or standards
- In confirming satisfactory combustion at the time of servicing in accordance with national or local regulations or standards or following servicing in accordance with appliance instructions
- In confirming satisfactory combustion following maintenance, in accordance with appliance instructions or national or local regulations or standards
What’s changed since the last update?
PD CLC/TS 50612:2016 supersedes PD CLC/TS 50612:2013 which is withdrawn. PD CLC/TS 50612:2016 includes a technical change with respect to PD CLC/TS 50612:2013. That include:
- The Scope of the 2013 guidance was limited to the use of portable electrical apparatus for the measurement of combustion flue gas parameters of gas-fired central heating boilers. The Scope of the 2016 guidance has been expanded to cover their use with gas-fired central heating boilers, domestic gas-fired air heaters, independent gas-fired space heaters, gas cooking appliances, and domestic gas-fired water heaters
