Preface

This is the second edition of CAN/CSA-M4254-1, Agricultural machinery - Safety - Part 1: General requirements, which is an adoption without modification of the identically titled ISO (International Organization for Standardization) Standard 4254-1 (third edition, 2005-08-01). This Standard supersedes the previous edition published in 1996 as CAN/CSA-M4254.1, Tractors and machinery for agriculture and forestry - Technical means for ensuring safety - Part 1: General (adopted ISO 4254-1:1989).

Scope

This part of ISO 4254 specifies the general safety requirements and their verification for the design and construction of self-propelled ride-on machines and mounted, semi-mounted or trailed machines used in agriculture. In addition, it specifies the type of information on safe working practices (including residual risks) to be provided by the manufacturer.

This part of ISO 4254 deals with significant hazards (as listed in Annex A), hazardous situations and events relevant to this agricultural machinery used as intended and under the conditions foreseen by the manufacturer (see Clause 4). For compliance with European Directives, Annex C is additionally applicable.

This part of ISO 4254 is not applicable to - tractors, - aircraft, - air-cushion vehicles, or - lawn and garden equipment.

This part of ISO 4254 is not applicable to environmental hazards, road safety, electromagnetic compatibility, vibration or power take-off (PTO) and PTO drive shaft guarding between self-propelled machines/tractors and the first bearing of recipient machinery. It is not applicable to hazards related to maintenance or repairs to be carried out by professional service personnel.

NOTE ISO 14982 specifies test methods and acceptance criteria for evaluating the electromagnetic compatibility of all kinds of mobile agricultural machinery.

This part of ISO 4254 is not applicable to machines which are manufactured before the date of its publication.

All of the hazards dealt with by this part of ISO 4254 will not necessarily be present on a particular machine. For any machine covered by this part of ISO 4254, the provisions of the part of ISO 4254 directly applicable to that type of machine, if available, take precedence over the provisions of this part of ISO 4254.
