Textual Amendments
F1 Substituted by Commission Regulation (EU) No 1235/2011 of 29 November 2011 amending Regulation (EC) No 1222/2009 of the European Parliament and of the Council with regard to the wet grip grading of tyres, the measurement of rolling resistance and the verification procedure (Text with EEA relevance).
The conformity of the declared fuel efficiency and wet grip classes, as well as the declared external rolling noise class and declared value, must be assessed for each tyre type or each grouping of tyres as determined by the supplier, according to one of the following procedures:
a single tyre or tyre set is tested first. If the measured values meet the declared classes or external rolling noise declared value to within the tolerance defined in Table 1, the test is successfully passed; and
if the measured values do not meet the declared classes or external rolling noise declared value within the range defined in Table 1, three more tyres or tyre sets are tested. The average measurement value stemming from the three tyres or tyre sets tested is used to assess conformity with the declared information within the range defined in Table 1; or
where the labelled classes or values are derived from type approval test results obtained in accordance with Directive 2001/43/EC, Regulation (EC) No 661/2009, or UNECE Regulation No 117 and its subsequent amendments, Member States may make use of measurement data obtained from conformity of production tests on tyres.
Assessment of the measurement data obtained from the conformity of production tests must take into account the allowances defined in Table 1.
| Measured parameter | Verification tolerances |
|---|---|
| Rolling resistance coefficient (fuel efficiency) | The aligned measured value shall not be greater than the upper limit (the highest RRC ) of the declared class by more than 0,3 kg/ 1 000 kg. |
| External rolling noise | The measured value shall not be greater than the declared value of N by more than 1 dB(A). |
| Wet grip | The measured value shall not be lower than the lower limit (the lowest value of G ) of the declared class.] |
