Hi Joe
Glad you found the Forum in its new location.

Self-righting bollards are required to conform to BS 8442:2015, which includes:

13.1.5 Conspicuity panels
Conspicuity panels shall be applied to the front and sides of all RSRB types; rear
conspicuity panels are optional. Conspicuity panels shall be retroreflective,
fluorescent and yellow in colour.
NOTE RSRBs rely on the brightness of retroreflective panels to be conspicuous at
night. Daytime conspicuity of these devices is enhanced by the use of fluorescent
yellow material.
The minimum projected area of the front or side conspicuity panels shall
conform to Table 6. Where both faces display a traffic sign both shall display a
conspicuity panel. The lower edge of the front conspicuity panel shall be a
minimum of 100 mm and a maximum of 200 mm above the ground line.
Table 6 Projected area of the conspicuity panels
Projected area, mm2
Front view Side view
150 000 20 000

BS EN 12899-2:2007 covers normal internally illuminated bollards. It has lots on the dimensions but doesn’t seem to give the minimum size of retrofeflective panels.
So apart from that, I think it’s up to the engineer to design what is safe and sensible.]]> Thu, 25 Aug 2022 13:39:52 GMT https://members.theihe.org/forums/posts.aspx?group=214541&topic=1705827 https://members.theihe.org/forums/posts.aspx?group=214541&topic=1705827
Hi Simon – Thanks for your comments.

What we actually have on site are standard roadside/townscape type bollards but with red/white reflective bands.

Think Glasdon Admiral type of thing but with a smaller reflector arranged (correctly) to show red/white at the nearside/offside kerb lines.

I’m waiting for two manufacturers to come back to me but all I can find is info about hazard marker posts in TSM, Ch.4 and a Traffic Advisory Leaflt (Think it’s 03/13) that mentions considering the conspicuity of bollards.

And that’s about it…

The context is that a local worthy is claiming that the reflectors are too small and therefore illegal. The boss is looking for some info to shut the argument down before it gets stirred up on social media…]]> Thu, 25 Aug 2022 13:40:35 GMT https://members.theihe.org/forums/posts.aspx?group=214541&topic=1705828 https://members.theihe.org/forums/posts.aspx?group=214541&topic=1705828
Diagram 560 (S2-6-2) gives a minimum of 75 mm diameter for a circular reflector, or 45 cm² for a rectangular one. So arguably a reflector on a marker post should comply with that. But it may well be legal to put up a smaller reflector if you deem it not to be a traffic sign.]]> Thu, 25 Aug 2022 13:40:54 GMT https://members.theihe.org/forums/posts.aspx?group=214541&topic=1705829 https://members.theihe.org/forums/posts.aspx?group=214541&topic=1705829
…and TSRGD, by default, would have a 560 as flat, not curved as it would be if fitted to something like an Admiral. So I think you’d have to argue, as Simon says, that the reflector attached to the bollard isn’t a sign due to the curvature.

This is why things like the Ensign and Mini-Ensign bollard, although the bulk of the product is circular, have flat areas for fitting signs onto.

Quite where “flat” would put something such as a Flexmaster legally, is another – but closely related – matter.]]> Thu, 25 Aug 2022 13:41:19 GMT
