Definitions of DIN EN 13 724
DIN EN 13724 replaces the previously valid DIN 32617 and specifies the requirements and test methods for mail slots which are valid in accordance with the manufacturer installation instructions. DIN EN 13724 considers protection and break-in safety as well as user-friendliness and security for the user and ergonomy and efficiency for the deliverer. The mailboxes marked with DIN EN 13724 or DIN in the JU catalogue comply without exception with there quirements laid down in the standard.

DIN EN 13724, among other things, contains the following provisions (excerpt):

Type 1
1.   Use in outdoor areas
2.   Indoor use
3.   Mail slots in through-wall mailboxes
4.   Mail slot in doors or door side wall

Larger formats
1. Portrait format – Mail slot opening 30 - 40 x 325 - 440 mm
2. Landscape format – Mail slot opening 30 - 40 x 230 - 280 mm

Corrosion and water intrusion
Grade 0  No specified resistance
Grade 3  Good resistance
Grade 4  Very good resistance

Security (burglary prevention)
Grade 1 Standard resistance (e.g. 200 different lockings)
Grade 2 Increased resistance (e.g. 500 different lockings)

Installation height of mail slot opening
For ergonomic reasons, the slot should range between 700 and 1,700 mm (for intercom systems, we recommend 1,200 to 1,450 mm height).

Furthermore, DIN EN 13724 contains guidelines and notes on the effort required to open and close the flap, fire protection regulations, confidentiality, removal safety, distance measurements, mail stacking height. The fulfillment of the DIN EN 13724 requirements must be proven by the correspondingly defined test requirements.

DIN standard
All our products marked with the DIN symbol comply with DIN EN 13724.

General information
Mailboxes, tray folds  and letter distribution systems are to be arranged in such a way that they are at any time easily accessible and handy, whereby private banks of mailboxes and individual inhouse mailboxes should be attached in such a way that they can be operated without entering the buildings. Note: According to Landgericht Berlin, judgment as of 11.05.1990, AZ 29 S 20/90, non-compliance with the DIN standards resulted in rent reductions.

The powder-coating for JU products has a layer density of 100 µm and is baked at approx. 200 ° C. The colouring is possible with all colours of the RAL colour chart, whereby assemblies can be designed in different colour shades. Assemblies made of aluminum can be provided with anodised coloured tones according to the colour table of the main catalogue.

JU colour palette
The colour reproduction according to the JU colour palette on page 180 is only approximation. The RAL colour, the anodised colour and the RAL colour chart are binding for the precise colour. Due to different material characteristics, a 100 % colour match is not possible. This also applies upon presentation of a colour sample. Therefore, certain colour variations are inevitable. In the event of slight colour deviations within the light-dark tolerance as well as in the case of anodised parts, slight deviations can be acceptable for the customer.
