Technical Information, Safety Regulations and CE-Labels

CE-Labels

EC guidelines for machines 93/44/EEC

Although pneumatic and electropneumatic components are used for systems and machines to which this guideline applies, the guideline does not apply to the components themselves, unless they are to be considered as "safety components".

These are defined as follows:
A safety component is a part that is sold separately and which is specially developed, manufactured and labelled for safety functions. Standard components which are installed into a safety device are not classified as safety components and do not have to bear CE labels. It is advisable, however, to have these parts certified at an official inspection site.

As a consequence:
Pneumatic and electronic components are not to bear CE labels. Mechanical engineers who have to declare their machine as in conformity with "guidelines for machines" can find the necessary technical data such as pressure, temperature, voltage etc. in the respective catalogues.

Electromagnetic compatibiliy EMV 89/336/EEC

Electropneumatic components such as electromagnetic valves, signal transmitters, electropneumatic control systems were originally subject to the EMC guidelines. However, the 92/31/EEC amendment has changed the stipulations.
This amended guideline defines an "appliance" as a finished serviceable product and which the end-consumer can operate as an individual apparatus.

As a consequence:
Rotorcomp components do not require certification. Nor do they have to bear CE labels. Because the customer often needs these evaluations, however, all major components are being currently tested and the evaluations recorded.

CE-Labels

The following table summarises the guidelines pertaining to the delivery and application of components and systems which are supplied by Rotorcomp within the European Union.

The guideline in detail:
The 93/68/EEC guideline defines the CE product label for products to which the above-listed guideline applies. This guideline also determines the size and shape of the CE label. The delivery of products without CE labels after the validation date is prohibited when a CE label is required. It is also prohibited to confer a CE label on products which do not require one. It is therefore important that the documents accompanying the products state which guideline applies to the products. When the products are imported into a member country of the EU, the CE label must be furnished by the manufacturer or supplier.

"Simple pressure vessels" guideline 87/404/EEC
A pressure vessel is defined as follows: welded vessel, produced in series, made of steel or aluminium for the purpose of containing air or nitrogen with an excess pressure of more than 0,5 bar. There are two categories of pressure vessels, determined by the energy stored: Category A: The product of excess pressure (bar) and volume (l) is > 50 bar/litre.
Category B: The product of excess pressure (bar) and volume (l) is > 59 bar/litre.

The safety requirements are:

• Category A:
  • Security clearance
  • EC-certifcation or EC inspection certificate from an officially authorised inspection site
  • CE-label
• Category B:
  • Manufacture in accordance with the current level of technology in the respective
  • country of origin
  • No CE label
• All pressure vessels must be provided with the following technical data in compliance with the applicable guideline:
  • max. working pressure
  • max. and min. working temperature in °C product designation
  • product designation
  • volume in litres
  • manufacturer's name
