out by Intertek and
witnessed by Worley
Parsons

5. Preparation for the Test
Fitted with ceramic pillars, side plates
and phase separators. Clad with K-
Mass™
19kV DC applied for 1 minute without
breakdown prior to test

6. 1100°C for 1 hour
• Required furnace temperature reached after 7min and 44 seconds. The
test then began
• A constant 4kVDC voltage was maintained for the duration of the test
• Leakage was monitored throughout the test
• There was no breakdown

7. After the Test
Some cooling down is required!

8. Positive Result
• Maximum recorded
temperature within the
box was 349°C
• After cool down 19kV
DC was re-applied and
the enclosure passed
