Annex E
(normative)

Noise Test Code for roughing and scouring machines
E.1 Scope
This noise test code complements EN 12545 for the determination and declaration of the noise emission from
roughing and scouring machines. EN 12545 and this Annex shall always be used jointly.
E.2 Normative references
See EN 12545:2000, Clause 2.
E.3 Definitions
E.3.1 Test Tool
An abrasive band or pad, for roughing and scouring footwear components, mounted on a wheel or on a belt,
of specified material, dimensions and form.
E.3.2 Test Workpiece
For shoe upper roughing and scouring machines, a shoe upper, together with insole, of resin finish, full grain
bovine upper leather having a thickness of 1,5 mm ± 0,2 mm and a circumference of 630 mm ± 10 mm.
For component roughing or scouring machines, a component of synthetic leather having a thickness of
4 mm ± 0,2 mm, of hardness 80 shore (A). It shall have dimensions of 280 mm x 280 mm and 4 corners of
length 30 mm set at 45 degrees.
E.3.3 Test cycle
For roughing or scouring: a specified number of roughing or scouring operations; and a specified time period.
E.4 Description of machinery family
As defined in 3.1 and 3.2.
E.5 Determination of the 'A'-weighted sound power level
E.5.1 General
See EN 12545:2000, Clause 5.

---------------------- Page: 4 ----------------------

EN 930:1997/A1:2004 (E)
E.5.2 Measurement procedure
The machine shall be operated three times through its test cycle. The arithmetic mean of the three values of
the A-weighted sound power level in dB shall be calculated, recorded and reported.
Where any microphone position is obstructed by the standing operator, that position shall be excluded from
the test.
E.6 Determination of A-weighted emission sound pressure level at the workstation
E.6.1 General
See EN 12545:2000, Clause 6 and the following.
E.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 as follows
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 roughing or scouring
band measured in a direction parallel to the centre line of the machine and displaced a distance of
0,20 m ± 0,02 m to the right of the centre line.
The microphone shall be located directly above this reference point at a height of 1,60 m ± 0,05 m.
E.6.3 Measurement procedure
The machine shall be operated three times through its test cycle. The arithmetic mean of the three values of
the A-weighted time averaged sound pressure level in dB shall be calculated, recorded and reported.
E.7 Mounting conditions
See EN 12545:2000, Clause 7.
E.8 Operating conditions
E.8.1 Automatic component roughing machines shall be set to run at 13 m/s or 4000 rpm and shall use 36
grain emery paper of dimensions 1300 mm x 150 mm.
E.8.2 For automatic component roughing, the workpiece feed rate shall be 10 m/min ± 1%; the band/pad
pressure setting shall be that recommended by the manufacturer. The feeding shall be linear, a single
component at a time, with a minimum of 30 workpieces roughed/scoured during the test cycle which shall
extend over 1 minute or 20 components, whichever is the greater.
E.8.3 For automatic shoe scouring machines, the workpiece scouring rate shall be 15 s/workpiece. The
feeding shall be linear, a single component at a time, with a minimum of 20 workpieces scoured during the
test cycle, which shall extend over 5 minutes or 20 workpieces, whichever is the greater.
E.8.4 Manual roughing and scouring machines shall be set to run at 4000 rpm. The abrasive used shall be
2000 mm x 300 mm emery tape (36 grain).

EN 930:1997/A1:2004 (E)
E.8.5 For manual roughing (see Figure 3 of this document) the test cycle shall consist of 30 toe roughing
operations over a noise measurement time period of 3 minutes. Each toe roughing operation shall be of at
least 2 seconds duration. Test workpieces from the same batch shall be used throughout the test cycle.
Details of the shoe upper construction shall be recorded and reported.
E.8.6 For manual scouring machines the test cycle shall consist of 15 scouring operations over a noise
measurement time period of 3 minutes. Each scouring operation shall be of at least 6 seconds duration. Test
workpieces from the same batch shall be used throughout the test cycle. Details of the shoe upper
construction shall be recorded and reported.
E.8.7 If resilient mounts are fitted, that fact shall be recorded and reported. All measurements shall be
carried out with the extraction system switched off, and this fact shall be reported.
E.8.8 The machine under test shall be switched on and left to idle for a period of at least 30 minutes before
the test commences.
E.8.9 If the specified values given in this noise test code are not fulfilled, these deviations shall be recorded
and reported. Other parameters which are not specified in this noise test code shall be recorded and reported.
E.9 Measurement uncertainty
See EN 12545:2000, Clause 9.
E.10 Information to be recorded
See EN 12545:2000, Clause 10.
E.11 Information to be reported
See EN 12545:2000, Clause 11. It is recommended that the type of mountings, conditions of test, material
scoured or roughed and noise data obtained be entered on a Data Sheet, an example of which is given in
Figure E.1.
E.12 Declaration and verification of noise emission values
