BS 7671 :2018 + A4 :2026 Roman Numerals

While we have Mr K’s attention, might I also enquire how to properly refer to the regulation Andy mentioned? Should it be five two seven dot two dot four, thereby emphasising the part, chapter, section, sub-section and regulation? I do recall an IEE video of the distant past being very explicit in that regard. 

Hi lyledunn , yes, 'five two seven dot two dot four' is the convention we used, although strictly if you wanted to emphasise the CHAPTER, it would be 'fifty two', but this isn't part of the Regulation number.

The convention for Regulation numbering is <section>.<subsection>.<number>, although there can be a number of levels of sub-section, so we have Regulations such as 531.3.5.3.1 (five three one dot three dot five dot three dot one.

In Part 7, there are no Chapters only Sections. In particular, if you delete the part 7 section and first dot, if there is a Regulation in Parts 1 to 6 or Part 8 with the same number, the Part 7 Regulation replaces the one in the other parts for that location only. For example, Regulation 701.411.3.3 replaces Regulation 411.3.3 in locations within the scope of Section 701.
