Cestna vozila - Varnost mehanskih tesnil na tahografih - Zahteve in postopki preskušanja

Ta evropski standard določa pogoje za določanje nazivne moči, toleranc in predstavitev tehničnih karakteristik proizvajalca za kondenzatorske enote za hlajenje s kompresorji z iztiskanjem. Ti vključujejo enostopenjske kompresorje ter eno- in dvostopenjske kompresorje z vgrajenim sredstvom za podhlajevanje tekočine. To je potrebno zato, da je mogoče opraviti primerjavo različnih kondenzatorskih enot. Podatki se navezujejo na zmogljivost hlajenja in absorbirano moč ter vključujejo zahteve za zmogljivost pri delni obremenitvi, kjer je to primerno.

Key 1 vehicle unit 2 cabling 3 motion sensor Figure 1 — Tachograph system 3.2 tachograph or recording equipment equipment intended for installation in road vehicles to display, record, print, store and output automatically or semi-automatically details of the movement, including the speed, of such vehicles, and details of certain periods of activity of their drivers 3.3 motion sensor part of the tachograph providing a signal representative of vehicle speed and/or distance travelled 3.4 vehicle unit tachograph excluding the motion sensor and the cables connecting the motion sensor Note 1 to entry: The vehicle unit may be a single unit or several units distributed in the vehicle, provided that it complies with the security requirements of Regulation 165/2014; the vehicle unit includes, among other things, a processing unit, a data memory, a time measurement function, two smart card interface devices for driver and co-driver, a printer, a display, connectors and facilities for entering the user’s inputs. 3.5 seal mechanical device marked with a unique identifier and designed for a single use, which is externally affixed to the gearbox and the sensor, and other possible sensitive part as defined on the tachograph type approval, and is designed to show visual evidence of tampering or intrusion to the system SIST EN 16882:2017

EN 16882:2016 (E)

6 Note 1 to entry: In certain configuration, a seal can be composed of different parts to fulfill its aim, as for example, a closing device and a wire. Note 2 to entry:

Seals need to be designed and constructed so that tamper attempts create and leave evidence of that tampering. Note 3 to entry: All grades and types of seals require inspection to indicate whether tampering has occurred. 3.6 defeated seal seal which has been opened or removed and replaced or reconstructed without detectable evidence of tampering 3.7 seal tampering attempt to open, remove, replace or reconstruct a seal 3.8 tamper evidence irreversible tell-tale indication that an attempt has been made to open, remove, replace or re-construct the seal Note 1 to entry: It’s a mechanical variation obvious and irreversible. Note 2 to entry: It can’t be considered as tamper evidence a modified part of the product, which can recover its initial state by applying an external physical source. Note 3 to entry: Examples of tamper evidence include a change in the colour of the material, in surface texture, cracks, indentations, abrasions, etc. Note 4 to entry: Tamper evident indicators are recognizable by normal examination under the usual circumstances prevailing in practice without technical aids (such as a magnifying glass or microscope). 3.9 tampered seal opened, removed, replaced or reconstructed seal with tamper evidence 3.10 indicativeness ability to reveal evidence after attempts have been made to tamper with the seal 3.11 wire seal length of wire secured in a loop by some type of seizing device EXAMPLE Wire seals include: crimp wire, fold wire and cup wire seals. Note 1 to entry: The seizing device can be plastic or metal and its deformation is one indication of tampering. 3.12 rotating seal formed by at least two elements: the main body and the rotating element Note 1 to entry: The internal mechanism rotates on its axis without auxiliary tools within the main body in one direction engaging and retaining the two wire ends.

Figure 4 — example of tail seal 3.14 security label seal paper or plastic backing with adhesive that gives visual evidence of tampering 4 Seal Requirements 4.1 General These requirements shall be applied to any type of seal. The marking requirements are given in Clause 7. All seals should be easy to fit correctly on the item to be sealed and, once in situ, be easy to check for correct fitment and integrity. Correct handling and fitting of seals is at least equal if not greater in importance than selection of the correct seal. A poorly chosen but correctly fitted seal may provide security; however, a well-chosen but incorrectly fitted seal will provide no security. Seals shall be sufficiently durable, strong, and reliable so as to prevent accidental breakage and early deterioration (due to environmental conditions, chemical action, vibration, shock, etc.) in normal use. SIST EN 16882:2017

EN 16882:2016 (E)

10 All types of seals shall be capable of being affixed quickly. Tachographs seals are typically subjected to the harsh environments of road transport industries. Sand and dust, salt spray, grease, snow, ice and grime can be expected to coat the seal. Physical shock and vibration are commonly encountered as a result of handling and transport operations. Mechanical seals shall be constructed to be fit for their intended purposes. 4.2 Requirements to traction 4.2.1 First requirement (for the system composed by the wire and the seal) As shown in Figure 5, a value of 13 kg has to be applied in the longitudinal direction and the seal shall not break.

EN 16882:2016 (E)

11 4.2.2 Second requirement At a higher power, the seal or the wire shall brake before the opening of the seal in order to show the tampering evidence: the load shall be slowly applied until the seal forcibly opens or is otherwise broken. On different application points shown in Figure 6, when the parts are assembled, the seal shall not permit the rotation of the sensor more than 90°.

An example of an incorrect seal installation is shown in Figure 7. SIST EN 16882:2017

Figure 8 — Correct seal installation The sensor cannot be rotated more than 90° without causing permanent damage to the sealing system. Requirements for installation: All seals should be easy to fit correctly on the item to be sealed and once in situ be easy to check for positive engagement of the locking mechanism(s). 4.4 Identification marks 4.4.1 General Regulatory authorities may require identifiers that go beyond the requirements of this European Standard, such as in the following cases. The normative Annex A shall be applied. SIST EN 16882:2017

EN 16882:2016 (E)

Check that all the elements are correctly assembled and you cannot separate them. If existing, pull the wire (or tail) by hand and be sure that both ends are within the locking mechanism of the seal. If existing, check that the tamper visual detector is valid. Check that the seal is correctly marked and printed regarding Clause 7. 5.2 Environmental test specification for the motion sensor seals 5.2.1 Temperature Operating and storage temperature limits: The system will function over a temperature range of
