Free movement of goods Free movement of goods is one of the 4 basic principles in European Community (EC). Beside the free movement of goods the EC established also: • free movement of services, • free movement of capital and, • free movement of workers (people). To establish free movement of goods EU introduced the following principles: harmonization of essential requirements, mutual recognition of conformity assessment procedures , and prevention of new barriers for trade.
Single Market Free movement of goods is a cornerstone of the single market. The mechanisms in place to achive this aim are based on prevention of new barriers to trade mutual recognition and technical harmonisation. Member states of EC: Austria, Belgium, Czech Republic, Cyprus, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Italy, Ireland, Latvia, Lithuania, Luxemburg, Malta, Netherlands, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, United Kingdom; And member states of EFTA: Norway, Iceland, Lichtenstein.
Harmonisation of requirements for products Harmonisation of: • Technical legislation (essential requirements); • Standards; • Conformity assessment procedures; • Market surveillance activities.

New Approach Directives 4(4) Member states of EC have to implement the New Approach Directives in national technical legislation without any modifications. It is a duty of Member states to cancel all national technical legislation which is in contrary with New Approach Directives.
New Approach Directive Conformity assessment procedures Product complies with all applicable NAD (and EN standards), there are no additional requirements in any member state. The product has free access to the internal market of EC.
Standardisation Harmonised EN standards (the reference numbers are published in Official Journal) are essential tool to implement requirements of NAD. Application of harmonised standards is voluntary. The European Commission gave the mandate for preparation of harmonised EN standards to following institutions: CEN (common standards and standards not in the scope of CENELEC and ETSI), CENELEC (electrotehnical standards), and ETSI (telecommunication standards).
Basic structure of New Approach Directives Standard elements of the New Approach Directives: • Scope (defines the range of products or phenomena covered); • Placing on the market and putting into service; • Essential requirements; • Free movement; • Presumption of conformity; • Safeguard clause; • Conformity assessment procedures; • Notified Bodies (requirements); • CE marking; • Coordination of implementation; • Transposition and transitional provisions.
Purpose of Machinery directive The Directive lays down essential requirements for human health and safety mostly concerning operators and persons near to machinery. The essential safety requirements do not directly concern environmental protection or the technological performance of machinery. Some of them can obviously help to ensure these. By way of an example, intrinsic reduction of machinery noise for the operator helps to reduce environmental noise. It is nevertheless possible that the essential safety requirements are difficult to reconcile with other requirements; the collection of gases from machinery and their discharge outside can be an environmental hazard; compliance with safety clearances can give rise to food hygiene problems. Standardization will endeavour to reconcile these various safety requirements. In the technical fields not covered by a European Directive, the Member States remain free to adopt regulations that are in line with the Treaty.
Scope 1(4) Directive addresses machinery and safety components. The guiding principle is that machinery is fundamentally “mechanical”. However, there are some basic definitions which help to determine what is “machinery”: • an assembly of parts; • the parts must be linked. This does not exclude machinery which is sold dismantledfor ease of transport or in kit form, as the manufacturer is obliged to design hismachinery in accordance with the Directive. • one of the parts must move. This movement must result from external energy(electricity, battery, fuel, etc.) or stored energy (spring, weight). • for a specific application. This implies that machinery which is unfinished, to theextent that it cannot function, is not covered by the Directive.
Scope 2(4) • the term “machinery” also covers an assembly of machines or complex installation. A “complex installation” means an assembly of machinery, appliances and mechanisms which, in order to contribute to the same result, generally the same production, are arranged and installed so as to be interdependent in operation. • Safety components: • electro-sensitive devices to detect persons (non-material barriers, sensor mats, electromagnetic detectors, etc.); • logic units which ensure the safety functions of bi-manual controls; • automatic movable screens (power-operated guards) to protect metalworking presses, injection or compression plastics- or rubber-moulding machines with manual loading or unloading; • roll-over protective structures (ROPS); • falling-object protective structures (FOPS).
Scope 3(4) The examples below illustrate definition of a “safety component”. • emergency stopping devices; • non-return valves designed as safety devices for equipment’s hydraulic systems; • safety belts and restraining devices in the event of overturning; • control or monitoring modules of safety-related parts of control systems, such as the position detectors in a locking mechanism; • products preventing undesired operation of machinery; • products preventing repetition of a machine cycle; • temperature-control products or systems to keep machinery within safe operating limits; • smoke or dust extraction systems for machinery; • guards and their locking mechanisms; • noise reduction enclosures; • anti-derailment mechanisms for suspended lifting machinery; • load control devices for lifting equipment; • hold-to-run controls.
Products excluded from Machinery directive 1(3) The products excluded from the scope of this Directive: • machinery whose only power source is directly applied manual effort, unless it is a machine used for lifting or lowering loads, • machinery for medical use used in direct contact with patients, • special equipment for use in fairgrounds and/or amusement parks, • steam boilers, tanks and pressure vessels, • machinery specially designed or put into service for nuclear purposes which, in the event of failure, may result in an emission of radioactivity, • radioactive sources forming part of a machine, • firearms,
Products excluded from Machinery directive 2(3) • storage tanks and pipelines for petrol, diesel fuel, inflammable liquids anddangerous substances. • means of transport, i.e. vehicles and their trailers intended solely for transporting • passengers by air or on road, rail or water networks, as well as means of transport inso far as such means are designed for transporting goods by air, on public road orrail networks or on water. Vehicles used in the mineral extraction industry shall notbe excluded, • seagoing vessels and mobile offshore units together with equipment on board suchvessels or units, • cableways, including funicular railways, for the public or private transportation ofpersons, • agricultural and forestry tractors, as defined in Article 1(1) of Council Directive74/150/EEC,

Essential health and safety requirements – Annex 1 1(9) • The obligations laid down by the essential health and safety requirementsapply only when the corresponding hazard exists for the machinery or safety component inquestion when it is used under the conditions foreseen by the manufacturer. • The essential health and safety requirements laid down in this Directive aremandatory. However, taking into account the state of the art, it may not bepossible to meet the objectives set by them. In this case, the machinery mustas far as possible be designed and constructed with the purpose ofapproaching those objectives. • The essential health and safety requirements have been grouped according tothe hazards which they cover. • Machinery presents a series of hazards which may be indicated under morethan one heading in this Annex. • The manufacturer is under an obligation to assess the hazards in order toidentify all of those which apply to his machine; he must then design andconstruct it taking account of his assessment.
Essential health and safety requirements – Annex 1 2(9) Definitions For the purpose of this Directive: • ‘danger zone’ means any zone within and/or around machinery in whichan exposed person is subject to a risk to his health or safety; • ‘exposed person’ means any person wholly or partially in a danger zone; • ‘operator’ means the person or persons given the task of installing,operating, adjusting, maintaining, cleaning, repairing or transportingmachinery.
Essential health and safety requirements – Annex 1 3(9) • General requirements: Machinery must be so constructed that it is fitted for its function, and can be adjusted and maintained without putting persons at risk when these operations are carried out under the conditions foreseen by the manufacturer.
