are performed during production, before using a tool, the operator must always sts ars, modifications or damage. Keeping the dielectric properties unchanged in time e hanical, chemical or thermal stress the tool may be subjected to. In case the in- c ool cannot be considered safe for use in live installations. Always wear protective

STS PERFORMED DURING PRODUCTION TE

Dimensional test: All the dimensions of the tools must comply with the design specifica- tions.

100% visual test: es of the tools All the surface finish xternally visible must be free from e defects

Crash test: °C, the tool is hit After 2 hours at -25 a specific weight three times (by such e standard); the as provided for by th st not show any insulating handle mu signs of damage.

Electrical insulation test: Following immersion in water for 24 hours, the tool is subjected to a voltage of 10 kV for 3 minutes. Current dissi- pation must not exceed such values as provided for by the standard.

-25°

Penetration test: pplied to the tool A weight of 2 kg is a r two hours. Later handle at +70 °C fo applied to the area a voltage of 5 kV is mechanical pressure that is subjected to gns of current pas- for 3 minutes. No si e shown. sing through must b

Adhesion test: after 168 hours at +70 °C, the tool is subjected to a load of 500 N to check that the handle does not slip off.

500N

Mechanical test: fy such mechanical The tools must satis ments as provided performance require O standards for in the relevant IS

Marking indelibility test: Following the friction test with isopropyl alcohol, markings must remain legible.

test: Flame propagation owards the tool A flame is directed t ng the next 20 for 10 seconds; duri must not exceed a seconds, the flame height of 120 mm.
