A shoe upper, last and insole.
C.3.3 Test Cycle
A specified number of lasting operations, using test workpieces, within a specified noise measurement time
period.
C.4 Description of machinery family
As defined in 1.1.
C.5 Determination of the 'A'-weighted sound power level
C.5.1 General
See EN 12545:2000, Clause 5.
C.5.2 Measurement procedure

EN 931:1997/A1:2004 (E)
Where any microphone position is obstructed by the standing operator, that position shall be excluded from
the test.
C.6 Determination of the A-weighted emission sound pressure levels at the
workstation
C.6.1 General
See EN 12545:2000, Clause 6 and the following.
C.6.2 Position of microphone
The microphone shall be located adjacent to the operator in a position as defined below, with an operator
standing at the workstation on the centre line of the machine. The microphone's position is defined relative to
a reference point on the ground plane on which the operator stands.
The reference point shall be at a horizontal distance of 0,4 m ± 0,05 m in front of the machines measured in a
direction parallel to the c
