Translation of "Indice de rugosité d'une particule " (French → English) :

[14] Strictly speaking, there is no known safe level of exposure for some pollutants such as particulate matter, but WHO guidelines are set at low risk levels and regularly revised.

Member States may apply random measurements instead of continuous measurements for benzene, lead and particulate matter if they can demonstrate to the Commission that the uncertainty, including the uncertainty due to random sampling, meets the quality objective of 25 % and the time coverage is still larger than the minimum time coverage for indicative measurements.

Those particles thus suggest certain qualities, although that does not mean that they can be regarded as a descriptive indication in terms of Article 7(1)(c) of Regulation No 40/94.

Even if the Commission has provided guidance on measuring particulate matter, further harmonisation and research are needed.

3. In this Chapter the expression "newsprint" means uncoated paper of a kind used for the printing of newspapers, of which not less than 65 % by weight of the total fibre content consists of wood fibres obtained by a mechanical or chemi-mechanical process, unsized or very lightly sized, having a surface roughness Parker Print Surf (1 MPa) on each side exceeding 2,5 micrometres (microns), weighing not less than 40 g/m2 and not more than 65 g/m2.

(14) Whereas new provisions for on-board diagnostics (OBD) should be introduced with a view to permitting an immediate detection of failure of anti-pollution vehicle equipment and thus allowing a significant upgrading of the maintenance of initial emissions performance on in-service vehicles through periodic or kerbside control; whereas, however, OBD are at a less developed stage for diesel vehicles and cannot be fitted on all such vehicles before 2005; whereas installing an on-board measurement system (OBM) or other systems to detect any faults by measuring individual pollutants emitted shall be permissible provided that the OBD system integrity is maintained; whereas in order for the Member States to ensure that vehicle owners meet the ...[+++]ir obligation to repair faults once they have been indicated, the distance travelled since the fault is indicated shall be recorded; whereas on-board diagnostics systems must offer unrestricted and standardised access; whereas motor vehicle manufacturers must provide the information required for the diagnosis, servicing or repair of the vehicle; whereas such access and such information are required to ensure that vehicles may be inspected, serviced and repaired without hindrance throughout the European Union, and that competition in the market for vehicle parts and repairs is not distorted to the disadvantage of part manufacturers, independent vehicle-part wholesalers, independent repair garages and consumers; whereas manufacturers of spare or retrofit parts will be obliged to make the parts they manufacture compatible with the on-board diagnostic system concerned with a view to fault-free operation assuring the user against malfunctions;
