LVD Vs Machinery Directive

How can we help?

RN Electronics can offer consultation services to help you understand the requirements of the Machinery Directive and the Low Voltage directive. RN electronics can offer comprehensive safety testing services to meet the requirements of the Low Voltage Directive. We can also offer safety testing services to test simple machines to cover the requirements of the machinery directive.

Machinery Directive

Machinery directive harmonises the safety requirements for machines put into service in Europe.
The directive applies to:
• Machines
• Interchangeable equipment
• Safety components
• Lifting accessories
• Chains, ropes and webbing
• Removable mechanical transmission devices
• Partly completed machinery

The following definitions apply:
a) ‘Machinery’ means:
• an assembly, fitted with or intended to be fitted with a drive system other than directly applied human or animal effort, consisting of linked parts or components, at least one of which moves, and which are joined together for a specific application,
• an assembly referred to in the first indent, missing only the components to connect it on site or to sources of energy and motion,
• an assembly referred to in the first and second indents, ready to be installed and able to function as it stands only if mounted on a means of transport, or installed in a building or a structure,
• assemblies of machinery referred to in the first, second and third indents or partly completed machinery referred to in point (g) which, in order to achieve the same end, are arranged and controlled so that they function as an integral whole,
• an assembly of linked parts or components, at least one of which moves and which are joined together, intended for lifting loads and whose only power source is directly applied human effort;

b) ‘Interchangeable equipment’ means a device which, after the putting into service of machinery or of a tractor, is assembled with that machinery or tractor by the operator himself in order to change its function or attribute a new function, in so far as this equipment is not a tool;

c) ‘Safety component’ means a component:
• which serves to fulfil a safety function,
• which is independently placed on the market,
• the failure and/or malfunction of which endangers the safety of persons, and
• which is not necessary in order for the machinery to function, or for which normal components may be substituted in order for the machinery to function. An indicative list of safety components is set out in Annex V, which may be updated in accordance with Article 8 (1) (a);

d) ‘Lifting accessory’ means a component or equipment not attached to the lifting machinery, allowing the load to be held, which is placed between the machinery and the load or on the load itself, or which is intended to constitute an integral part of the load and which is independently placed on the market; slings and their components are also regarded as lifting accessories;
e) ‘Chains, ropes and webbing’ means chains, ropes and webbing designed and constructed for lifting purposes as part of lifting machinery or lifting accessories;

f) ‘Removable mechanical transmission device’ means a removable component for transmitting power between self-propelled machinery or a tractor and another machine by joining them at the first fixed bearing. When it is placed on the market with the guard it shall be regarded as one product;

g) ‘Partly completed machinery’ means an assembly which is almost machinery but which cannot in itself perform a specific application. A drive system is partly completed machinery. Partly completed machinery is only intended to be incorporated into or assembled with other machinery or other partly completed machinery or equipment, thereby forming machinery to which this Directive applies.

Low Voltage Directive

The Low Voltage Directive applies to all electrical equipment designed for use with a voltage rating of between 50 and 1000 V for alternating current and between 75 and 1500 V for direct current. Voltage ratings refer to the voltage of the electrical input or output, not to voltages which may appear inside the equipment.

Borderline between Low Voltage Directive and Machinery Directive

The following electrical equipment is excluded from the scope of the machinery directive:
• Household appliances intended for domestic use.
• Audio and Video equipment.
• Information technology equipment.
• Ordinary office equipment.
• Low-voltage switchgear and control gear.
• Electric motors.
Low voltage directive is applicable to the above equipment.

General Notes

The Low Voltage Directive covers all risks arising from the use of electrical equipment, including not just electrical ones but also mechanical, chemical (such as, in particular, emission of aggressive substances) and all other risks. The Low Voltage Directive also covers health aspects of noise and vibrations, and ergonomic aspects as far as ergonomic requirements are necessary to protect against hazards in the sense of the Directive. The Machinery Directive is mutually exclusive with the Low Voltage Directive, so that either one or the other will apply but never both. Annex 1 of the Machinery Directive contains requirements for electrical safety which precisely mirror those of the LVD.

Mandatory use of notified body when using Machinery Directive

Type examination is mandatory for the following types of machines and components.
• Circular saws / sawing machinery
• Hand-fed surface planing machinery for woodworking.
• Thicknessers for one-side dressing.
• Band-saws
• Combined wood working machinery.
• Hand-fed tenoning machinery.
• Hand-fed vertical spindle moulding machinery for working with wood.
• Portable chainsaws for woodworking.
• Presses, including press-brakes.
• Injection or compression plastics-moulding machinery.
• Injection or compression rubber-moulding machinery.
• Machinery for underground working
• Manually loaded trucks for the collection of household refuse incorporating a compression mechanism.
• Removable mechanical transmission devices including their guards.
• Guards for removable mechanical transmission devices.
• Vehicle servicing lifts.
• Devices for the lifting of persons or of persons and goods.
• Portable cartridge-operated fixing and other impact machinery.
• Protective devices designed to detect the presence of persons.
• Power-operated interlocking movable guards.
• Logic units to ensure safety functions.
• Roll-over protective structures (ROPS).
• Falling-object protective structures (FOPS).
