Particulate contamination
Attention: Airborne particulates (including metal flakes or particles) and reactive
gases acting alone or in combination with other environmental factors such as
humidity or temperature might pose a risk to the device that is described in this
document. Risks that are posed by the presence of excessive particulate levels or
concentrations of harmful gases include damage that might cause the device to
malfunction or cease functioning altogether. This specification sets forth limits for
particulates and gases that are intended to avoid such damage. The limits must not
be viewed or used as definitive limits, because numerous other factors, such as
temperature or moisture content of the air, can influence the impact of particulates
or environmental corrosives and gaseous contaminant transfer. In the absence of
specific limits that are set forth in this document, you must implement practices that
maintain particulate and gas levels that are consistent with the protection of human
health and safety. If NEC determines that the levels of particulates or gases in your
environment have caused damage to the device, NEC may condition provision of
repair or replacement of devices or parts on implementation of appropriate remedial
measures to mitigate such environmental contamination. Implementation of such
remedial measures is a customer responsibility.
