1.4 Quality Guaranteed
1.4.1 General
The Slam® Trans–series is designed, certified, manufactured and tested under ISO
9001:2000 quality system as well as additional requirements of the Directive 94/9/EC (ATEX).
The Slam® Trans–series is designed and tested according to the latest directives and
standards. The referred directives and standards of the production date in case are stated on
the Declaration of Conformity which is included in the delivery.
1.4.2 Individual testing reports
Each CentaurSlam®–unit has its own individual serial number and is provided with an
original, individual testing report when leaving the factory. The year of manufacture is
specified on the type label of the equipment. Following tests have been done for Slam®
Trans–units according to standards relating to portable transformer for explosion hazardous
area. The Declaration of Conformity is specifying the relevant standards. The testing report
included in the delivery specifies the results of the factory tests for that particular unit. The
testing report typically specifies the following tests:
PE –resistance test
The purpose of this test is to measure persistence of earth conductor.
Vital test for electrical safety as well as explosion safety because of e.g static electricity
control.
The test current is 10 A (current) and the overall resistance should not exceed 0,5 ohm.
Operation under load
Each of the sockets is tested with 10 A of load. The output voltage has to be as specified for
the particular type of transformer
High voltage test (electrical strength)
The purpose of this test is to measure leakage current trough insulation. Vital test for
revealing broken components or similar failures which can not be identified visually. For
transformer there are three tests runned: Primary, Secondary and Primary agaist Secondary.
Testing voltage applied is 2130VDC. Maximum leakage current is 5mA.
Test of expected use of equipment
The transformer is subjected to shaking and vibration – to see that all the internal wires are
properly attached and components are not loose.
Operational test of transformer and accessories
