What is the BS ISO 20474 series of standards about?
The BS ISO 20474 series of standards specifies the general safety requirements for earth-moving machinery as defined in BS EN ISO 6165:2012 Earth-moving machinery. Basic types. Identification and terms and definitions, each of those requirements being common to two or more earth-moving machinery families. It is applicable to machine attachments, and derivative machinery designed primarily for equipment used to excavate, load, transport, drill, spread, compact or trench earth rock and other materials.
Who is this standard for?
These standards will be relevant to anyone that works with earth-moving machinery including manufacturers, purchasers, hirers and users of earth-moving equipment. The BS ISO 20474 series will also help UK manufacturers into other markets, particularly those emerging markets outside the EU who are looking to adopt international standards. While EN 474 is still the principal standard for the EU, BS ISO 20474 brings an internationally consistent approach to safety.
Why should you use this standard?
This 13 part series deals with all significant hazards, hazardous situations and events relevant to earth-moving machinery when used as intended or under conditions of misuse reasonably foreseeable by the manufacturer. It specifies the appropriate technical measures for eliminating or reducing risks arising from relevant hazards, hazardous situations or events during commissioning, operation and maintenance. BS ISO 20474-1 is intended to be used in conjunction with the other parts of the series, which address the provisions which are specific to particular machine families. For multi-purpose machinery, all of those parts of BS ISO 20474 whose requirements cover the functions and applications of such machines are applicable.
The following individual parts of the standard includes safety requirements for different types of earth-moving machinery:
- BS ISO 20474-2: Required for dozers
- BS ISO 20474-3: Required for loaders
- BS ISO 20474-4: Required for backhoe loaders
- BS ISO 20474-5: Required for hydraulic excavators
- BS ISO 20474-6: Required for dumpers
- BS ISO 20474-7: Required for scrapers
- BS ISO 20474-8: Required for graders
- BS ISO 20474-9: Required for pipelayers
- BS ISO 20474-10: Required for trenchers
- BS ISO 20474-11: Required for landfill compactors
- BS ISO 20474-12: Required for cable excavators
- BS ISO 20474-13: Required for rollers
What’s new?
Many new safety requirements and protective measures have been included as well as normative annexes in Part 1 that contain requirements for:
- Elevating operator’s stations
- Lifting devices used in object handling
- Earth-moving machinery used underground in non-explosive atmospheres
