Inspection of electrical machine equipment

Nen-en-iec 60204 and SASO inspection
Inspection of electrical machine equipment

INTRODUCTION

Any machine marketed or used within the European Union must comply with the safety and health requirements of the Machinery Directive. Directive 2006/42/EC covers machinery, interchangeable equipment, safety components, hoisting and lifting tools, chains, cables and straps, removable mechanical transmission systems and unfinished machinery.

The assessment standard for the electrical equipment of a machine is the NEN-EN-IEC 60204-1, which may be supplemented per country. This is the case, among other things, with exports of machinery to Saudi Arabia, where the national derogations from Saudi Arabia apply.

Inspection in accordance with NEN-EN-IEC 60204-1

The purpose of an inspection according to the Machinery Directive is to verify that the machine in question complies with the applicable standards and regulations, whereby various inspections and combinations are possible in consultation:

  • assessment of the machine design;
  • attending the commissioning;
  • electrical installation inspection, including functional testing of safety systems;
  • verification of the intended safety level of the entire machinery;
  • verification of the individual safety chains with regard to the required Performance Level.

The inspection can take place prior to commissioning, but can also be carried out periodically as a basic condition to ensure the safety of the working environment.

In consultation, the inspection can be extended with an additional thermographic inspection of the machine and associated control box, and in addition to safety, the continuity of the installation can often be guaranteed.

INSPECTION METHODOLOGY

We assess the machine based on the NEN-EN-IEC 60204-1 standard: 'Safety of machines – Electrical equipment of machines – Part 1: General requirements'. This assessment is carried out through a visual inspection, measurements and tests.

In the event of an initial or handover inspection, it is also checked whether the applicable documents, such as electrical diagrams and a manual, are available and complete.

The inspection is summarised in a report that can form part of the Technical Construction Dossier of the manufacturer. Thereafter, the manufacturer may issue a declaration of conformity and affix a CE marking to the machine being inspected (if the machine is not covered by Annex IV to Machinery Directive 2006/42/EC). This declaration of conformity is also part of the SASO documentation package.
