The laboratory of the J.S. Hamilton Notified Body has testing capabilities in the field of explosion-proof construction equipment, competence, appropriate equipment, our own flameproof enclosure testing chamber and flexibility are our advantages.
We perform tests in the field of:
- measurement of geometrical dimensions,
- the pressure resistance of shields, static and dynamic pressure
- and dynamic pressure,
- protection against the transmission of explosions,
- measurement and determination of reference pressure,
- electrical strength of insulation,
- insulation clearances,
- cell and battery capacities,
- short-circuit resistance of cells and batteries,
- testing of transformers,
- hot thermal resistance
- cold thermal resistance,
- free fall strength,
- thermal tests, temperature rise,
- IP degree of protection,
- explosive gas concentration measurements
- measurements of explosive gas and air flows,
- non-standard – engineering tests.
We perform tests of electrical equipment operating in potentially explosive atmospheres:
flameproof covers “d”,
gas shields with overpressure “p”,
equipment with equipment protection level (EPL) Ga,
dust explosion protection equipment enclosure type “t”
reinforced construction “e”
intrinsically safe execution “i”,
non-sparking execution type “n”
hermetic protection “m”,
sand shielding “q”,
optical power testing “op is”
oil shields “o”.
The laboratory is accredited by the Polish Centre for Accreditation for testing flameproof casings for use in potentially explosive atmospheres.
