Test areaU.K.

ISO 11094:1991

In case of dispute, measurements shall be carried out in the open air on the artificial surface (point 4.1.2 of ISO 11094:1991)

Environmental correction K 2A U.K.
Measurement in the open airU.K.

K 2A = 0

Measurements indoorsU.K.

The value of the constant K 2A, determined without artificial surface and in accordance with Annex A to EN ISO 3744:1995, shall be ≤ 2,0 dB in which case K 2A shall be disregarded

Operating conditions during testU.K.
Mounting of equipmentU.K.

The leaf collector shall be positioned in the natural manner for normal use in such a way that the inlet of the collecting device is situated (50 ± 25) mm above the centre of the hemisphere; if the leaf collector is hand-held it shall be held either by a person or by a suitable device

Test under loadU.K.

The leaf collector shall be operated at its nominal speed with the nominal air flow in the collectiong device stated by the manufacturer

Period of observationU.K.

The period of observation shall be at least 15 seconds

Note:U.K.

If a leaf collector can be also used as a leaf blower it shall be tested in both configurations, in which case the higher value shall be usedU.K.
