Step by step

The CE mark is linked to the EU common market and is based on three key principles: the free movement of goods, persons and capital. EU member states have lifted trade barriers among themselves and established a common policy towards non-EU countries. In this way, an area was created in which the flow of goods takes place, as it used to be on the domestic market, but now throughout the EU. This area was called the Common Market. After the establishment of the common market, barriers that could hinder trade had to be removed, such as the requirements for, for example, product quality and safety. Over the years, each country has created its own system of regulations and standards, often very different from the others. This meant that a producer wanting to sell his product in another country would have to meet different requirements. EU member states have decided to eliminate this problem and harmonize the system of product conformity assessment. In the interests of consumer safety, standard systems could not be abolished. It was therefore decided to harmonize national systems so that goods throughout the EU would be subject to the same requirements. Bearing in mind many Member States, a simplified approach to technical harmonization has been developed, creating European legal acts, called New Approach Directives setting out the essential safety requirements for various product groups that must be met before being placed on the market or put into service on the EU market. For machines and robots, this is a machinery directive.

Who gives the CE mark?

In order to determine compliance with the requirements of directives and harmonized standards, a declaration and CE marking have been created, which are a declaration by the manufacturer or an authorized representative that the product complies with the essential directives related to the product. The cooperating robot has the CE mark as an incomplete machine, because it requires e.g. a gripper and installation in a specific application. However, for robotic applications, the CE mark is issued by Integrator, which performs the entire compliance process.

Collaboration with people by Collaborative robots [Cobots] occurs in many different applications. The collaborative robot has built-in safety systems ensuring its safe interaction with the human, nevertheless each application is different and before we allow Cobot to specific application, it is necessary to make measurements on the factory floor, prepare documentation, perform risk assessment and analysis to finally issue a CE declaration. CoRobotics & Partners have the necessary knowledge to complete the application certification process. Regardless of this, we provide regular trainings in the field of safety requirements for collaaboration with Cobots.

When integrating a new collaborative robot, we offer audits, measurements and analysis related to:

  • Compliance with legal requirements: Machinery Directive 2006/42 / EC, EN-ISO 12100, EN 10218, EN 14120, EN-ISO 13855, EN-ISO 13857, EN-ISO 13849-1,
  • Compliance with the recommendations of ISO-TS 15066
  • Identification of hazards and risk assessment in relation to the work cell, associated equipment, robot arm, gripper and objects in the gripper
  • Preparation and completion of documentation, including preparation of workplace instructions
  • Marking the robot with the CE mark

Step by step

1. Risk assesment

We analyse the workplace and the type of task to be performed. We identify ways to use Cobot and analyse possible cases of wrong use. The risk assessment begins with defining the machine and identifying hazards. Then we estimate the risk and evaluate it. At the end of the assessment, we determine whether the level of risk is tolerated.

2. Verification of the level of security

After the risk assessment in point 2 and determining its level, we can assess compliance with the EN-ISO 13829-1 standard in accordance to the required level of safety.

3. Verification of documentation

We examine the documentation in accordance with the Machinery Directive 2006/42 / EC in terms of availability and completeness. At this stage, we make any additions to the content required to ensure work safety.

4. Safety test

We carry out security checks at the robot’s work cell.

5. Measurement of collision parameters

We measure parameters for particular types of threats, including deadlocks and impacts by the robot, taking into account the speed of the robot, the mass transferred and the point energy transmitted by the arm, the gripper and the object being conveyed.

6. Final safety solutions

After conducting the assessment, analysis and measurements from point 1-5 determine whether standard Cobot safety systems are sufficient, whether additional security measures should be applied, be it physical sensors, photocells or only information: staff training, instructions, warning boards.

7. CE marking

After proceeding out items 1-6, we can proceed to issue the CE declaration.
