Environmental Aspects
This chapter includes information about the environmental impact of EXTER oper-
ator terminals.
More information can be found on the manufacturer’s web site.
5.1 General Environmental Aspects
The manufacturer’s activities meet internal requirements as well as those of the
SS-EN ISO 9001:1994 and SS-EN ISO 14001:1996 international standards.
5.2 Environmental Impact of the Operator
Terminals
5.2.1 Mechanical Components
The aluminum and stainless steel used in the mechanical components are judged to
be non-environmentally hazardous. The expanded rubber packing for the front and
the expanded polyethylene packing for the display contain an adhesive that is not
classified as environmentally hazardous.
Screws may have undergone the following surface treatments: Bright nickel-plating
or bright zinc-plating. The membrane keyboard is made of polyester with silver wir-
ing. On some models the keyboard contains LEDs.
Display frames and CF covers are made of halogen-free plastic, PC/ABS.
5.2.2 Electronics
Circuit board
The circuit board is largely surface mounted, which means less use of solder com-
pared with through-hole mounting.
The solder material consists mainly of tin (approximately 63%) and lead
(approximately 27%). There may be traces of other substances such as copper and
silver. The tin solder is analyzed regularly. The plastic in the printed circuit board
contains the flame-retardant Tetrabromobisphenol-A (TBPA, brominated). There is
no polybrominated diphenyl ether (PBDE)
The electronics are complex and almost all elements of the periodic table are
represented.
Display
There is a separate circuit board for the display. The liquid crystals in the display are
cyclohexane compounds. The fluorescent tube contains mercury and lead solder.
Batteries
The operator terminal contains a button cell lithium battery (Li/MnO2).
The battery is not classified as environmentally hazardous by the Swedish Battery Or-
dinance (1997:645).
Note:
All operator terminals produced after July 1, 2006 will be RoHS compliant.
