In Mandate M/111, there is a clear requirement for durability in use. In order to meet this requirement,
EN 1463-1 specifies, in Annex ZA Table ZA.1, the standard EN 1463-2 (Road test performance specifications).
However, in the current Table ZA.1, the classes S0 and R0 (no performance determined) are included (just as a way to reflect the result of the mentioned durability test, which requires 1-year of road exposure for the applicant studs) and some notified bodies have interpreted this as meaning that it is not required to test to EN 1463-2 and consequently CE marks are being granted without durability being tested. However, in other cases, the mentioned test has been carried out; therefore, both types of road studs are now in the market granting a “well different” class of CE-marking.
In order to rectify this unsatisfactory situation it is proposed to amend the requirement for “R” to become R1 to R4 - i.e. eliminating R0, which might have caused the confusion, and thus meaning that a road test has to be carried out and the requirement for durability is met. In addition, it is also proposed that the requirement for “S” is deleted as this is not necessary to also have this to ensure durability is tested. SIST EN 1463-1:2009

3 Terms and definitions For the purposes of this European Standard, the terms and definitions in CIE publication 17.4:1987 apply together with the following.
3.1 retroreflecting road stud (called “road stud” in this standard) horizontal guiding device that reflects incident light by means of retroreflectors (see 3.2) in order to warn, guide or inform road users
NOTE
Retroreflecting road studs may be constructed in either one or more integral parts and may be bonded to, anchored within or embedded within the road surface. The retroreflecting portion may be unidirectional or bidirectional, depressible or non depressible. This device may be either permanent (type P) or temporary (type T). 3.2
retroreflector device which reverses the direction of visible light striking it and returns it along a path substantially parallel to its original path
NOTE It may be made of glass (type 1), plastic (type 2) or plastic with an abrasion resistant surface (type 3). It may have a reflective coating at the back. 3.3
non depressible road stud substantially rigid road stud not designed to deform under the passage of traffic (type A)
3.4
depressible road stud road stud designed to have one or more parts which deform under traffic and recover to their original geometry after removal of the traffic load (type B)
3.5
bonded road stud
road stud fixed to the road surface using an adhesive applied to the stud and/or to the road surface at the time of installation
self-adhesive road stud
road stud precoated with adhesive
NOTE An adhesion enhancer (see 3.7) may be required under some climatic conditions. 3.7
adhesion enhancer
additional coating on the load bearing surface of the road stud or on the road surface which improves the performance of the adhesive bond
3.8
anchored road stud
road stud fixed to the road surface using an anchor or spigot
NOTE The anchor(s) or spigot(s) may be an extension of the road stud body or a separate part(s) supplied for the purpose. The principal load bearing interface of the road stud and the road is between the surface of the road and the underside of the road stud. 3.9
embedded road stud
road stud fixed into a prepared cavity of an appropriate dimension cut into the road surface
NOTE The principal load bearing interface of the road stud and the road is between a downward facing surface of the road stud and an upward facing surface of the cavity. 4 Types of road stud Road studs are classified in this European Standard in accordance with Tables 1, 2 and 3.
Table 1 - Classification of road studs by use
Use TypePermanent road stud 1) P Temporary road stud 2) T 1) Provides night-time warning guidance and information to road users.
2) Provides daytime and night-time warning guidance and information to the road user by stimulating the use of three senses. It is received visually and can be heard and felt through the rumble effect. Temporary road studs are used only at road construction/maintenance sites.
