Πρόταση ΑΠΟΦΑΣΗΣ ΤΟΥ ΣΥΜΒΟΥΛIΟΥ σχετικά με την προσχώρηση της Ευρωπαϊκής Κοινότητας στον κανονισμό αριθ. 67 της Οικονομικής Επιτροπής των Ηνωμένων Εθνών για την Ευρώπη περί εγκρίσεως τύπου ειδικών εξαρτημάτων των αυτοκινήτων οχημάτων που χρησιμοποιούν υγραέρια στο σύστημά τους πρόωσης

(υποβληθείσα από την Επιτροπή)

ΑΙΤΙΟΛΟΓΙΚΗ ΕΚΘΕΣΗ

1. Γενικά

Σε συνέχεια της απόφασης 97/836/ΕΚ του Συμβουλίου της 27ης Νοεμβρίου 1997, η ΕΚ κατέστη συμβαλλόμενο μέρος στην αναθεωρημένη συμφωνία του 1958 της Οικονομικής Επιτροπής των Ηνωμένων Εθνών για την Ευρώπη (ΟΕΕ/ΗΕ) στις 24 Μαρτίου 1998 και προσχώρησε σε 78 κανονισμούς συνημμένους στην ανωτέρω συμφωνία.

Το άρθρο 3 παράγραφος 3 της εν λόγω απόφασης προβλέπει ιδίως ότι η Κοινότητα έχει τη δυνατότητα να αποφασίσει την εφαρμογή ενός κανονισμού στον οποίο δεν έχει προσχωρήσει τη στιγμή που προσχωρεί στην αναθεωρημένη συμφωνία, εφόσον το Συμβούλιο εγκρίνει τον υπόψη κανονισμό με ειδική πλειοψηφία, μετά από σύμφωνη γνώμη του ΕΚ.

Κατά την 116η συνεδρίαση της "Ομάδας εργασίας επί της κατασκευής οχημάτων" της ΟΕΕ/ΗΕ ψηφίστηκε τροποποίηση του κανονισμού αριθ. 67 περί εγκρίσεως τύπου ειδικών εξαρτημάτων των αυτοκινήτων οχημάτων που χρησιμοποιούν υγραέρια στο σύστημά τους πρόωσης. Ο εν λόγω κανονισμός δεν περιλαμβάνεται στον πίνακα των αναγνωρισμένων από την ΕΚ κανονισμών που παρατίθεται στο παράρτημα ΙΙ της απόφασης 97/836/ΕΚ.

Ο κανονισμός αριθ. 67, όπως τροποποιήθηκε, αποσκοπεί κυρίως στην εξάλειψη των τεχνικών εμποδίων στην εμπορία των αυτοκινήτων οχημάτων μεταξύ των συμβαλλομένων μερών, εξασφαλίζοντας συγχρόνως υψηλό βαθμό ασφάλειας και προστασίας του περιβάλλοντος. Πρέπει να υπενθυμιστεί ότι η ΕΚ θα μπορέσει να προσχωρήσει στον κανονισμό 67, όπως αυτός τροποποιήθηκε, μόνο εφόσον η τροποποίηση αρχίσει όντως να ισχύει κατά την ημερομηνία ή τις ημερομηνίες που καθορίστηκαν στον εν λόγω κανονισμό. Προβλέπεται εξάλλου ότι ο κανονισμός αυτός θα ενσωματωθεί στο σύστημα έγκρισης των αυτοκινήτων οχημάτων και θα συμπληρώσει έτσι την ισχύουσα στην Κοινότητα νομοθεσία.

Πρέπει να υπογραμμιστεί ότι η ΕΚ θα αποφασίσει ως προς την προσχώρησή της στον επίμαχο κανονισμό με βάση το διαθέσιμο έγγραφο στις επίσημες γλώσσες της ΟΕΕ/ΗΕ (γαλλικά, αγγλικά και ρωσικά). Κατά συνέπεια, το κείμενο του κανονισμού αριθ. 67 επισυνάπτεται μόνο στη γαλλική και αγγλική έκδοση.

Σύμφωνα όμως με τις διατάξεις του άρθρου 4 παράγραφος 5 της απόφασης 97/836/ΕΚ, ο κανονισμός αριθ. 67 προτού τεθεί σε ισχύ θα δημοσιευθεί στην Επίσημη Εφημερίδα σε όλες τις επίσημες γλώσσες των Κοινοτήτων.

2. Περιεχόμενο της πρότασης απόφασης

Η πρόταση απόφασης αποσκοπεί στο να επιτρέψει στην Κοινότητα να προσχωρήσει στον κανονισμό αριθ. 67 της ΟΕΕ/ΗΕ περί εγκρίσεως τύπου ειδικών εξαρτημάτων των αυτοκινήτων οχημάτων που χρησιμοποιούν υγραέρια στο σύστημά τους πρόωσης.

b) One specimen shall be fatigue tested at a pressure cycling rate not to exceed 4 cycles per minute as follows:

i) held at 82?C while pressured for 10,000 cycles between 300 and 3,000 kPa;

ii)held at -20?C while pressured for 10,000 cycles between 300 and 3,000 kPa.

At the end of this test there shall be no leakage, or any visible sign of extrusion of any fusible metal used in the design.

c) Exposed brass pressure retaining components of pressure relief device shall withstand, without stress corrosion cracking, a mercurous nitrate test as described in ASTM B154 1/. The pressure relief device shall be immersed for 30 minutes in an aqueous mercurous nitrate solution containing 10 g of mercurous nitrate and 10 ml of nitric acid per litre of solution. Following the immersion, the pressure relief device shall be leak tested by applying an aerostatic pressure of 3,000 kPa for one minute during which time the component shall be checked for external leakage. Any leakage shall not exceed 200 cm3/h.

d) Exposed stainless steel pressure retaining components of pressure relief device shall be made of an alloy type resistant to chloride induced stress corrosion cracking.
