This European Standard specifies the technical requirements to minimise the hazards listed in Clause 4 which can arise during the commissioning, the operation and the maintenance of passenger stairs 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 authorised representative. It also takes into account some requirements recognised 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 stairs with seated driver;
b)   pedestrian controlled stairs;
c)   towable stairs equipped with powered means, e.g. for height adjustment, stabilisers;
d)   automatic levelling systems of stairs
for embarking/disembarking of passengers.
Powered should also be 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.
Those clauses of this standard that can apply may also be used as a guideline for the design of towable stairs without powered means.
This European Standard does not establish additional requirements for the following:
1)   persons falling out of an aircraft with the passenger stairs not in position;
2)   hazards resulting from a moving stairway (escalator);
3)   upper deck door access.
This part of EN 12312 is not applicable to passenger stairs which are manufactured before the date of publication by CEN of this standard.
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 passenger stairs.

This European Standard specifies a method for the determination of the content of undissolved substances, referred to as total contamination, in middle distillates, in diesel fuels containing up to 30 % (V/V) fatty acid methyl esters (FAME), and in neat FAME. The working range is from 12 mg/kg to 30 mg/kg and it was established in an interlaboratory study by applying EN ISO 4259 [2].
This European Standard in general applies to products having a kinematic viscosity not exceeding 8 mm2/s at 20 °C, or 5 mm2/s at 40 °C, e.g. diesel fuel as specified in EN 590 [1].
This test method may be used for diesel fuels containing more than 30 % (V/V) FAME and for petroleum products having a kinematic viscosity exceeding 8 mm2/s at 20 °C, or 5 mm2/s at 40 °C, however in such cases the precision of the test method is not defined.
NOTE 1   Excessive contamination in a fuel system can give rise to premature blocking of filters and/or hardware failure, and is therefore undesirable.
NOTE 2   For the purposes of this European Standard, the term "% (V/V)" is used to represent the volume fraction, φ, of a material.
WARNING - Use of this standard may involve hazardous materials, operations and equipment. This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.
