Engineering Information


All Enclosures are RoHS compliant.


Electromagnetic Interference (E.M.I.) is electronic pollution which is caused by rapidly
changing voltage. It can cause computational errors or wipe out complete memories,
much like electrostatic discharge (E.S.D.), if allowed to penetrate sensitive electronic
components. The Serpac E.M.I. enclosure will offer a higher degree of protection than
any paired surface. We recommend that all end manufactures conduct open field
measurement tests.


For a part to resist a particular blow without failure two conditions must be met:
  1. The part must absorb the total Kinetic energy of the blow, that is, the striker must
       be brought to zero velocity and then rebound.
  2. The stresses developed within the part must not exceed the fracture strength of
       the material.


Flammability tests cannot and do not measure material performance in a fire.
U.L. standard 94 defines two types of test. These tests lead to essentially six levels of ratings.


Depending on your final use and environment of operation it is likely a U.L. standard
will need to be met. Serpac can provide a custom material and certification for your
