used by non-skilled/non-instructed persons). Under this new coding system, a summary of the condition of the installation in terms of safety should be clearly indicated in Section E of the condition report. Observations, if any, should be categorised in Section K of the condition report, using the coding C1, C2 or C3 as appropriate. Any observations given a C1 or C2 classification should result in the overall condition of the installation being reported as unsatisfactory, whereas under the 17th Edition only a number 1 (requires urgent attention) allocated to an observation would normally result in the overall assessment of unsatisfactory.
What is the new inspection schedule in Appendix 6 for? The new inspection schedule provides a detailed breakdown of the inspection required on each aspect of the installation, to ensure that the work is carried out in an organised and efficient manner. Each item listed on the schedule that requires checking is accompanied by the relevant regulation number for ease of reference to the Wiring Regulations. In addition, the form provides a facility to indicate the outcome of the inspection of each item with either a tick (acceptable condition), a code C1 or C2 (unacceptable condition), a code C3 (improvement recommended), NV (not verified), Lim (limitation) or NA (not applicable); under the original 17th Edition, the
inspection of a general item would normally only result in a tick in a box.

Section 444 – Measures against electromagnetic disturbances Why has this new section been added? This is an entirely new section brought about by developments in CENELEC HD 60364-4-444 Measures against electromagnetic disturbances. In 1996, the Electromagnetic Compatibility (EMC) Directive (89/336/ EEC) was issued requiring electromagnetic compatibility of products being sold across Europe. The EMC Directive relies on harmonised standards with which products are to comply; the CE mark, for example, is a direct result of the work undertaken to remove trade barriers and, hence, allowed development of the EMC Directive. In 2004, the EMC Directive was modified as 2004/108/ EC and came into force in July 2007; the main change was the inclusion of fixed installations.
What does the section cover? Section 444 has been developed to provide the basic requirements and recommendations, both to enable the avoidance and reduction of electromagnetic disturbances and to meet the EMC Directive. The section includes guidance for the location and sources of electromagnetic disturbances relative to the positioning of other equipment,
