The best known
ESD cautionary symbol consists of a yellow hand in the act of reaching,
deleted by a bar, all within a black triangle. It is intended to
identify devices and assemblies that are susceptible to ESD. It
is now correctly used as follows:
- on individual
components and related documents to state: "this device is
static sensitive: do not touch without appropriate precautions"
- on assemblies
and related documents to state "includes static sensitive
components: take appropriate precautions"
- as part
of a sign identifying an area where sensitive devices are handled,
to warn all who approach it that precautions are required.
In its standard,
ESD S8.1-1993, the ESD Association introduced a new symbol. It is
similar to the one above left but without the bar and with an added
arc. It is intended to identify ESD protective materials. This new
symbol is shown above right and is now included in IEC 61340-5-1.
This symbol should appear on ESD protective products such as shielding
bags and boxes. The asterisk should be replaced with a letter indicating
the primary function of the item:
C - conductive, D - dissipative, L - low charging
(previously known as astatic or antistatic), and S for shielding.
suitable for use inside an EPA, such as field service mats, trolleys
and garments. the asterisk should be replaced with EPA.
