PART 8 Requirements applying to cones, cylinders and delineators

1.  A cone is to consist of a conically shaped device—

(a) the base of which is—

(i) of any single colour; and

(ii) a polygon having not more than eight sides, which would be contained wholly within a circle with a diameter of three quarters of the height of the cone; and

(b) which conforms to the provisions of British Standard BS EN 13422:2004+A1:2009(1) set out in paragraph 8.

2.  A cylinder is to consist of a cylindrically shaped device which conforms to the provisions of British Standard BS EN 13422:2004+A1:2009 set out in paragraph 8.

3.  A delineator is to consist of a flat device—

(a) of which the side intended to be exposed to traffic is coloured as shown in the diagram at item 4 of the table in Part 6 and the reverse side is either so coloured or coloured only grey or only red;

(b) which conforms to the provisions of British Standard BS 8442:2015(2); and

(c) of which the base is of any single colour, except that a reflectorised white line 100 mm wide at an angle of not more than 60 degrees to the road surface may be marked on one side of the base at right angles to the face of the delineator.

4.  The part of a cone, cylinder or delineator coloured white must, subject to paragraph 7, be illuminated with white retroreflecting material and the part coloured red (except, in the case of a delineator, on the reverse side when that side is coloured only red) may be illuminated with red retroreflecting material.

5.  Information about the ownership of a cone, cylinder or delineator may—

(a) in the case of a cone, be moulded—

(i) into the base in characters not more than 80 mm high in the same colour as the base;

(ii) into the conical body in characters not more than 40 mm high in the same colour as that body; or

(iii) as mentioned in both paragraphs (i) and (ii);

(b) in the case of a cylinder, be moulded into the lower of the two red parts of the cylinder in red characters not more than 40 mm high; and

(c) in the case of a delineator, be moulded into the base in characters not more than 80 mm high and in the same colour as the base.

6.  Information about the manufacture of a cone, cylinder or delineator required in order to comply with British Standard BS EN 13422:2004+A1:2009 or British Standard BS 8442:2015 (or, in either case, a corresponding EEA standard) and occupying an area not exceeding 30 square centimetres, may be indicated on the part coloured white in characters not exceeding 5 mm in height, leaving at least 90% of the remaining area of white colour illuminated with white retroreflecting material.

7.  There may be mounted on top of a cone a rotating device that—

(a) is red and not reflectorised; and

(b) displays a sign provided for at item 2 of the sign table in Part 6 of Schedule 2 which must be coloured amber, intermittently whilst rotating and constantly whilst static.

8.  In relation to each aspect of performance specified in column 2 of an item in the table below, a cone or cylinder must comply with the requirement or test specification of British Standard BS EN 13422:2004+A1:2009 specified in column 3.
