Postal services - Trays for international letter mail - Test methods and performance requirements
The standard defines the physical characteristics of a disposable container for letters and flats for exchange within Europe, to use a uniform postal container and to facilitate the exchange of letters within Europe. The dimensions of this "1 level" of container will constitute a first step of standardization. The following features will be defined: - inner dimension compatible with formats; - compatibility between trays and pallets dimensions; - rigidity; - impermeability; - closing; - sealing (optional); - positioning; - label's dimension; - number of cycle of use; - volume of folded containers.

Foreword
This document (CEN/TS 14482:2003) has been prepared by Technical Committee CEN/TC 331 “Postal services”,
the secretariat of which is held by NEN.
This document has been prepared under a mandate given to CEN by the European Commission and the European
Free Trade Association, and supports essential requirements of EU Directive(s).
At the request of CEN, the project (in CEN/TC 331/WG 4) was chaired by a representative from IPC (International
Post Corporation), a firm based in Brussels, owned by a number of European and North American postal operators.
IPC has set up an independent group of experts to study the requirements for a small postal container which can
replace the traditional mail bag in certain types of international mail handling. This type of container is known in the
postal industry as a tray. The Tray subgroup – an advisory body to the IPC – has agreed on the relevant
requirements for a postal tray.
Experts from the IPC Tray subgroup have joined the CEN/TC 331/WG 4 whose members are postal and materials
handling experts and include experts from manufacturing companies. The findings of the IPC Tray Subgroup have
been adopted by CEN/TC 331/WG 4.
Annex A is informative.
This document includes a Bibliography.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to anounce this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,
France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal,
Slovakia, Spain, Sweden, Switzerland and the United Kingdom.

Introduction
The European Union Commission stressed already in its Green paper on postal services in 1992 the need to
establish common rules for the development of community postal services and the improvement of quality of
service.
Furthermore the Commission has acknowledged the need for technical harmonisation to increase the
interoperability of postal networks in the member states and has given CEN a mandate to define fields where such
harmonisation could be useful and suggest priorities and timescales.

4 Requirements
The mail tray shall meet the following requirements:
4.1. Tray size requirements
Minimum internal tray dimensions shall accommodate mail of the following sizes with ease of handling:
Height Width
C4 353 mm 250 mm
C5 173 mm 250 mm
C6 120 mm 250 mm
4.2. Tray performance requirement
4.2.1 Compatibility
Trays and closures shall fit well onto each other, nest easily into each other and separate well from each other
without the use of undue force.
4.2.2 Compression
The trays shall meet a minimum compression strength requirement of 180 kg at a deflection of less than 10 mm
before failure.
NOTE: This represents a five high stack of trays each weighing 10 kg and a safety factor of 4,5, as specified in ISO
12048.
4.2.3 Durability
Trays shall withstand drop, vibration and crushing simulations as per the following:

SIST-TS CEN/TS 14482:2005
CEN/TS 14482:2003 (E)
4.2.4 Closure
The closure of the tray is to provide security during transit and handling. The closures shall fit well on the tray to
prevent tampering with the content. The closures shall be enclosed tightly to the tray by means of strapping in both
directions, once over the width and once over the length of the tray.
4.2.5 Flammability
Trays manufactured from plastic material shall meet requirements as specified in EN 60695-11-20. Trays made
from alternative materials shall meet similar requirements when tested with appropriate flammability tests.
4.2.6 Friction
The friction coefficient between tray and conveyor surface as specified in 5.2.5 shall not be lower than 0,31.
4.2.7 Handles/handholds
Handles/handholds shall be designed for ergonomically comfortable handling, with no sharp edges and as
referenced in prEN 1005-2.
4.2.8 Nestability
Nesting ratio of trays and closures to the one “tray and closure height” shall be a minimum of 1:5. The better the
nesting ratio the lower the transport cost for moving empty trays and closures.
4.2.9 Recyclability
Trays should be manufactured from a material which is recyclable as specified in EN 13430.
4.2.10 Stackability
Trays shall be stackable and inter-stackable. Trays that are stacked shall be placed on a flat, horizontal and level
surface and remain stable at up to 1,8 m stacking height.
4.2.11 Tare weight
The tray and closure shall meet the tray dimensions and durability requirements specified with a tare weight
remaining as light as possible. Because of the impact of tare weight on transport cost, the tare weight shall not be
higher than 10% of the maximum filled weight of the tray. The mail load capacity of the tray is determined by the
minimum tray dimensions specified in 4.1. The average tare weight shall not exceed 1050 g and the standard
deviation shall not be higher than 1% of the average weight.
4.2.12 Temperature resistance
Trays shall be capable of being handled at extreme temperatures, as specified in ISO 2233:
— from -35° C to 70° C there shall be materials stability such that the material shall maintain its essential shape for
up to 8 h
— at -35° C the trays shall be resistant to the drop test (perform the drop test on the edge of the loaded tray with
10 kg gross weight from 1 m high).
4.2.13 Weather resistance - Water spray exposure
The tray and closure shall be weather resistant with no more than 3% ingress of water as specified in EN 22875.

5 Test method
The following testing methods were designed to represent simulation of real life usage and handling in an
international mail exchange environment. The test methods intend to characterize the functionality, strength and life
span of trays used in the exchange of international mail. The tests are laboratory tests.
Life span is expressed as number of cycles successfully completed in the durability test (5.2.9), which is meant to
reflect the minimum number of trips the tray can make in real life before failure. The life span expressed as number
of cycles is not meant to be an indicator for the economic life span, although in general the higher the number of
cycles the higher the economic life span. Economic life span on the one hand is a function of materials / design /
manufacture and is defined by the technical specification of the tray, and on the other hand it is a function of the
equipment management determining circulation time and number of trays in circulation. These factors are outside
the scope of this Technical Specification.
The tests can be used as pre-production tests as well as postproduction tests. The test method allows for testing of
trays and closures manufactured using different tools and by different manufacturers.
5.1 Test sampling and tray preparation
A minimum of 50 samples, trays and closures, shall be made available to perform the tests. In case of a post-
production test, the 50 samp
