BS EN 13393:2001 – Packaging — Specification for edge protectors
1 Scope
This European Standard specifies the dimensions and physical properties of a range of edge protectors which are used in conjunction with tensional strapping.
2 Normative references
The following normative document contains provisions which, through reference in this text, constitute provisions of this European Standard. For dated references, subsequent amendments to, or revisions of, this publication, do not apply. However, parties to agreements based on this European Standard are encouraged to investigate the possibility of applying the most recent edition of the normative document indicated below. For undated references, the latest edition of the publication referred to applies (including amendments).

3 Product description
3.1 Shape
Edge protectors are manufactured in a wide variety of forms and sizes, which are categorized as follows.
3.1.1 Flat
Flat or strip form used for product protection, normally folded or wrapped around the edge during application.
3.1.2 Corner protectors
Small moulded, cut or formed pieces (up to 100 mm in length) used as edge protection where no additional packaging strength is provided.
3.1.3 Profiles
Pre-formed lengths (greater than 100 mm in length) used for edge protection or reinforcement.
3.2 Material
Edge protectors are normally (but not exclusively) manufactured from recycled materials: metal, plastic, paper,composite, miscellaneous.
3.3 General
Because they are manufactured from recycled materials, edge protectors themselves may be subject to minor irregularities.
Edge protectors shall not delaminate.
For multiple ply protectors, different colours may be visible.
3.4 Mechanical properties of profiles
Edge protectors are required to perform in a wide range of environments, some of which may affect performance. Edge protectors shall not delaminate under these conditions.
For this reason, test pieces shall be conditioned for 72 h according to EN ISO 2233.
Because the mechanical properties of profiles may be variable, five test pieces are measured.
3.4.1 Three-point bending strength test
A sample of 230 mm (±10 mm) is prepared in which the ends are smooth, free of burrs and parallel to one another.
The sample rests on two supports which are separated by 200 mm (see Figure 1).
The force is applied at a rate of 400 mm per minute (±2,5 mm per minute).
The maximum force in newtons (N) to failure is recorded (measure to 10 N accuracy).
3.4.2 Column crush strength test
A sample of 230 mm (±5 mm) is prepared in which the ends are smooth and free of burrs (see Figure 2).
The force is applied perpendicular to the length of the test piece in newtons (N) at a rate of 10 mm per minute (±2,5 mm per minute).
The maximum force in newtons (N) to failure is recorded (measure to 10 N accuracy).
