Introduction
This document intends to provide a uniform test procedure to test the effectiveness of the protective
measures for electrical safety for recurrent tests of current-using equipment and appliances during
their operating life time at work places.
This document can be considered by employers to support compliance with the European Directive
2009/104/EC concerning the minimum safety and health requirements for the use of work equipment
by workers at work and does not necessarily involve the manufacturer.
In general, test procedures for verification of products is the responsibility of the related product
technical committees. This document can be taken into consideration by product technical committees
if they need to take into consideration modified or additional tests for verification of products falling
within their scope.”
The described tests are simple and fast, well approved and safe for the testing person.
They can be carried out on site and/or in laboratories.
1 Scope
This document specifies the requirements of the test procedures to be applied for recurrent tests of
current-using electrical equipment and appliances for the verification of the effectiveness of the
protective measures and the permissible limits
This procedure is applicable to current-using electrical equipment connected at work places to final
circuits with a rated voltage above 25 V AC and 60 V DC up to 1 000 V AC and 1 500 V DC, and
currents up to 63 A. They can be either pluggable equipment type A connected to final circuits at work
places via a plug or permanently connected equipment.
This document assumes that the current-using equipment or appliances under consideration complies
with its related product standard, has been introduced on the market and is in use.
This document does not cover:
— tests after repair defined in EN 50678;
— type tests, routine tests, sample tests, special tests and acceptance tests for product safety nor
for product functional requirements.
NOTE 1 type tests, routine tests, sample tests, special tests and acceptance tests are usually defined in
product standards. This document does not replace tests covered by product standards.
This document does not apply to:
— devices and equipment that are part of the fixed electrical installations defined in
HD 60364 (all parts);
NOTE 2 For these devices, tests for initial and periodic verifications are covered by HD 60364-6.
— uninterruptible Power Supply (UPS), photovoltaic inverters and power converters, e.g. AC/DC
converters;
— charging stations for electro-mobility;
— stationary power supplies (generators);
— programmable Logic Controllers (PLC);
— power Drives;
— devices for EX-zones or for mining applications in general;
— products already covered by standards addressing similar topics such as:
a) medical equipment covered by EN 60601-1. For these devices, EN 62353 applies;
b) arc welding equipment covered by EN 60974-1. For these devices, EN 60974-4 applies;
c) machinery covered by EN 60204-1. For these devices, EN 60204-1 applies.
