European foreword
This document (prEN 415-8:2022) has been prepared by Technical Committee CEN/TC 146 “Packaging
machines – Safety”, the secretariat of which is held by UNI.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 415-8:2008.
The following significant changes have been made:
— Scope now includes needle strapping machines;
— Hand-held motor-operated electric strapping tools have been removed from the scope;
— Safety requirements have been rewritten so they are in line with EN 415-10:2014;
— Normative references have been changed to reflect the many changes that have been made to B1 and
B2 standards.
EN 415, Safety of packaging machines consists of the following parts:
— Part 1: Terminology and classification of packaging machines and associated equipment;
— Part 2: Pre‐formed rigid container packaging machines;
— Part 4: Palletizers and depalletizers;
— Part 5: Wrapping machines;
— Part 6: Pallet wrapping machines;
— Part 7: Group and secondary packaging machines;
— Part 8: Strapping machines;
— Part 9: Noise measurement methods for packaging machines, packaging lines and auxiliary equipment,
grade of accuracy 2 and 3;
— Part 10: General requirements.
This document has been prepared under a Standardization Request given to CEN by the European Com-
mission and the European Free Trade Association, and supports essential requirements of EU Di-
rective(s) / Regulation(s).
For relationship with EU Directive(s) / Regulation(s), see informative Annex ZA, which is an integral part
of this document.

Introduction
This document is of relevance, in particular, for the following stakeholder groups representing the market
players with regard to machinery safety:
— machine manufacturers (small, medium and large enterprises);
— health and safety bodies (regulators, accident prevention organizations, market surveillance etc.).
Others can be affected by the level of machinery safety achieved with the means of the document by the
above-mentioned stakeholder groups:
— machine users/employers (small, medium and large enterprises);
— machine users/employees (e.g. trade unions, organizations for people with special needs);
— service providers, e.g. for maintenance (small, medium and large enterprises);
The above-mentioned stakeholder groups have been given the possibility to participate at the drafting
process of this document.
The machinery concerned and the extent to which hazards, hazardous situations or hazardous events are
covered are indicated in the scope of this document.
This document is a type-C standard as stated in EN ISO 12100:2010.
The machinery concerned and the extent to which hazards, hazardous situations or hazardous events are
covered are indicated in the scope of this document.
When requirements of this type-C standard are different from those, which are stated in type- A or type-
B standards, the requirements of this type-C standard take precedence over the requirements of the other
standards for machines that have been designed and built according to the requirements of this type-C
standard.
The full set of requirements for machines in the scope of this document is composed by those given in
this document in conjunction with the relevant requirements of EN 415-10: 2014.
The Annex ZA of this document will not list the EHSR which are not relevant for this kind of machines or
are not covered for any other reason.

1 Scope
This document applies to strapping machines. This document established safety requirements for the
following groups of machines:
— Powered hand strapping tools;
— Semi-automatic strapping machines;
— Automatic strapping machines.
This document does not apply to:
— Strapping tools, where the strap tension is only applied by manual effort;
— Machines, which are foreseen to use paper as strap;
— Hand-held motor-operated electric strapping tools.
NOTE Hand-held motor-operated electric strapping tools see EN 60745-2-18:2009 and EN 62841-1:2015.
This document does not consider the following hazards:
— The use of strapping machines in potentially explosive atmosphere;
— The health, safety or hygiene hazards associated with the products that may be handled by the ma-
chines, but does include general advice on this subject;
— Hazards that are associated with decommissioning strapping machines.
Hazards associated with decommissioning of strapping machines are not considered and therefore ex-
cluded but should be part of the instruction manual (see Clause 6), together with suited measures, if nec-
essary.
