Introduction
The aim of this European Standard is to deal with vibration as a hazard and to provide methods for the measure-
ment and reduction of vibration emission transmitted to the whole body of drivers of GSE, when driving. For deter-
mining whole body vibrations under stationary operating conditions and hand-arm vibrations EN 1032:2003 is used.
It is intended that the results obtained can also be used to compare GSE of the same category or a given GSE
when equipped with different seats or tyres, etc.
Fitting different seats, changing the tyre specification, etc. can lead to different vibration values. Due to the specific
operation of GSE, however, EN 1032:2003 cannot be applied directly for whole body vibration under driving condi-
tions, and therefore, the preparation of this European Standard for GSE has become necessary.
This European Standard cannot be used for field measurements to determine the daily exposure of the driver to
vibration.
This European Standard is a Type C standard as stated in !EN ISO 12100".
The machinery concerned and the extent to which hazards, hazardous situations and events are covered are indi-
cated in the scope of this document.
When provisions of this type C standard are different from those which are stated in type A or B standards, the pro-
visions of this type C standard take precedence over the provisions of the other standards, for machines that have
been designed and built according to the provisions of this type C standard.
1 Scope
!This European Standard deals with whole body vibration as a significant hazard." It also specifies the
methods for determining the vibration emission transmitted to the whole body of drivers standing and/or seated on
freely moveable GSE, when driving for purposes of type evaluation, declaration and methods of verifying vibration
emission.
The test results are not applicable to the determination of whole body vibration exposure of persons.
!This European Standard is intended to be used in conjunction with the other parts of EN 1915, and with the
relevant part of EN 12312."

Aircraft ground support equipment - Specific requirements - Part 8: Maintenance or service stairs and platforms
SIST EN 12312-8:2018

1.1   General
This document specifies the technical requirements to minimize the hazards listed in Clause 4 which can arise during the commissioning, the operation and the maintenance of maintenance or service stairs and platforms when used as intended, including misuse reasonably foreseeable by the manufacturer, when carried out in accordance with the specifications given by the manufacturer or his authorized representative. It also takes into account some requirements recognized as essential by authorities, aircraft and ground support equipment (GSE) manufacturers as well as airlines and handling agencies.
These machines are designed to be used as aircraft ground support equipment with the intended use to serve aircraft in outdoor conditions on the apron. They can also be used indoors at hangars. The use of such equipment for operations not in conjunction with aircraft is not defined as intended use therein. Due to the good operational conditions on the apron, deviations from some clauses of EN 280 were deemed acceptable.
This European Standard applies to:
a)   self-propelled fixed or adjustable maintenance or service stairs and elevating platforms;
b)   towable maintenance or service stairs and platforms equipped with powered means, e.g. for height adjustment, stabilizers;
designed for aircraft maintenance or service purposes including access to the aircraft.
NOTE 1   Powered will be also understood as manual effort stored in springs or hydraulic accumulators, etc., the dangerous action of which can be produced or can continue after the manual effort has ceased or directly applied manual effort for lifting or lowering loads.
NOTE 2   Those clauses of this standard that can apply can also be used as a guideline for the design of towable maintenance or service stairs and platforms without powered means.
This European Standard does not apply to:
c)   maintenance docks either fixed to the ground or moveable only for docking procedure;
d)   ground support equipment specifically intended, built and equipped with a fluid system for aircraft de-icing and anti-icing (see EN 12312 6);
NOTE 3   This does not prevent aircraft de-icers meeting the requirements of EN 12312 6 from being used as a means of access for aircraft maintenance, e.g. windshield cleaning, etc.
e)   mobile elevating work platforms (MEWP) used at the airports for purposes other than aircraft maintenance, e.g. buildings and facilities (see EN 280).
No extra requirements on noise and vibration are provided other than those given in EN 1915 3 and EN 1915 4.
NOTE 4   EN 1915 3 and EN 1915 4 provide the general GSE vibration and noise requirements.
This European Standard does not deal with hazards in respect to a standard automotive chassis and from other vehicles on the apron.
This part of EN 12312 is not applicable to maintenance or service stairs and platforms which are manufactured before the date of publication of this standard by CEN.
This part of EN 12312 when used in conjunction with EN 1915 1, EN 1915 2, EN 1915 3 and EN 1915 4 provides the requirements for maintenance or service stairs and platforms.
1.2   Classification
For the purposes of this document, mobile elevating work platforms (MEWPs) used for aircraft maintenance access are divided into two main groups A and B. In addition, group C is considered as described in c) hereafter:
a)   Group A: MEWPs where the vertical projection of the centre of the platform area is always inside the tipping lines.
NOTE 1   See 5.2 hereafter for the specific requirements applying to Group A MEWPs.
b)   Group B: MEWPs where the vertical projection of the centre of the platform area may be outside the tipping lines.
NOTE 2   See 5.3 hereafter for the specific requirements applying to Group B MEWPs.
c)   Group C consists of maintenance or service access stairs, where persons are not elevated by the machine but climb a flight of steps.

Aircraft ground support equipment - Specific requirements - Part 12: Potable water service equipment
SIST EN 12312-12:2017

This European Standard specifies the technical requirements to minimize the hazards listed in Clause 4 which can arise during the commissioning, operation and maintenance of potable water service equipment when used as intended, including misuse reasonably foreseeable by the manufacturer, when carried out in accordance with the specifications given by the manufacturer or his authorized representative. It also takes into account some requirements recognized as essential by authorities, aircraft and ground support equipment (GSE) manufacturers as well as airlines and handling agencies.
This European Standard applies to:
a)   self-propelled potable water vehicles;
b)   towable potable water vehicles;
c)   moveable parts of ramp integrated systems,
designed for servicing aircraft and intended to be used under the conditions given in EN 1915-1:2013, 1.
No extra requirements on noise and vibration are provided other than those in EN 1915-3 and EN 1915-4.
NOTE   EN 1915-3 and EN 1915-4 provide the general GSE vibration and noise requirements.
This part of EN 12312 is not applicable to potable water service equipment which is manufactured before the date of publication of this standard by CEN.
This part of EN 12312, when used in conjunction with EN 1915-1, EN 1915-2, EN 1915-3 and EN 1915-4, provides the requirements for potable water service equipment.
