Overview of EN 13724 Standard:
This document outlines the European standard EN 13724, which specifies requirements for mailbox units, replacing the German DIN 32617 standard. It introduces stringent criteria to enhance mail security.

Main Requirements:

Classification of four types of letter openings: outside, inside, slide-through, and door/side wall.
Specification of two opening sizes: 325-400 mm for horizontal and 230-280 mm for longitudinal openings, with a height of 30-35 mm.
Corrosion resistance as per EN 1670 and water penetration resistance (240 hrs salt spray test).
Burglary resistance through sturdy materials and locks, with two security levels.
Capability to post a C4 format test envelope without folding or damage.
Letter openings' center line should be between 700 mm and 1700 mm, with exceptions allowing 400 mm to 1800 mm.
No sharp edges on letter opening components for safety.
No windows on mailboxes to ensure confidentiality.
Devices to prevent unauthorized mail removal.
Minimum volume requirement of a 40 mm stacked height in C4 format.

Testing and Compliance:
All products have been tested against this standard, with some exceptions due to space constraints during renovations. The standard is a recommendation but becomes obligatory when included in tenders.

Advantages of Compliance:

Ensures smooth mail posting without creases.
Eliminates the need for trips to the post office for large mail.
Prevents wet mail and storage space issues.
Guarantees high quality through the use of appropriate materials.

Colour Specifications:
The document lists various RAL and non-RAL colours available for RENZ products. The standard finish is RAL 9007 with a satin finish and gloss level of 55-70%. It is noted that due to different powders and coating processes, the shade may not precisely match other manufacturers' RAL 9007 colours. Customers are advised to request an original Renz RAL 9007 colour sample for accurate matching. Other RAL colours can be supplied upon request.
