Universal equipments for aspiration, suspension, dust
circulation tests, with the aim of measuring the effective resistance rate
of materials and wrappings to dust, according to procedures expressed by
the international norms below:
ASTM C 150-56 tipo I, ASTM C
150-84, UNE 20-324, FIAT- 7.G216093/EN 60529:1993- SAE J575 Giugno 92- BLS
30 EE-101, EN 60529, EN-60598-1:1997, DIN 40046 (pagine 46, 47 e 48),
MIL-STD 202 (metodo 110A), RENAULT 36-05-010, MIL-STD 810C (metodo 510.1),
BS 2011 (parte 2.1 test L),
With this generation of Perani equipment it is possible
to develop IP tests with different diffusion procedures, composition
(f.i., cement powder as foreseen by ASTM C 150-84, or adequately sieved
talcum powder as foressen by UNISCE 20-324-89,...).
The quantity of
items to be tested in dusty environmental standard conditions is relevant:
electric and electronic systems, for internal and external illumination,
signalling automatisms, capsules, wrappings for tin
contents. |
