ANNEX III U.K.METHOD OF MEASUREMENT OF AIRBORNE NOISE EMITTED BY EQUIPMENT FOR USE OUTDOORS

PART B NOISE TEST CODES FOR SPECIFIC EQUIPMENT

8. COMPACTION MACHINES U.K.

(i) NON-VIBRATING ROLLERS U.K.

See No 0

(ii) VIBRATING ROLLERS FOR RIDE-ON OPERATORS U.K.

Basic noise emission standard U.K.

EN ISO 3744:1995

Operating conditions during test U.K.

Mounting of equipment U.K.

The vibrating roller shall be installed on one or more appropriate elastic material(s) such as air-cushion(s). These air-cushions shall be made of a supple material (elastomer or similar) and shall be inflated to a pressure ensuring that the machine is elevated by at least 5 cm; resonance effects shall be avoided. The dimension of the cushion(s) shall be such that the stability of the machine under test is ensured

Test under load U.K.

The machine shall be tested in a stationary position with the engine at rated speed (stated by the manufacturer) and the moving mechanism(s) disconnected. The compacting mechanism shall be operated using the maximum compaction power corresponding to the combination of the highest frequency and the highest possible amplitude for that frequency as declared by the manufacturer

Period of observation U.K.

The period of observation shall be at least 15 seconds

(iii) VIBRATORY PLATES, VIBRATORY RAMMERS, EXPLOSIVE RAMMERS AND WALK-BEHIND VIBRATING ROLLERS U.K.
