Hazardous Area Zoning System
As previouslymentioned along side the division system inNorth America exists a zoning system based on
IEC legislation. This is themethod adopted by Europe and other countries.
Europe& International
Classification
To establish requirements and
safety standards that are the same
throughout Europe, the EC commis-
sion has compiled product-related
“EuropeanDirectives.” These direc-
tives apply to all types of products.
The corresponding European stan-
dards developed the European
Committee for Electrotechnical
Standardization (CENELEC).
In Europe the areas are classified
using the ATEX legislation. This
legislation is based onmethods
developed by the IEC (International
Electric Council)with the aim of
creating one global standard.
CENELEC (EuropeanCommittee for
Electrotechnical Standardization)
and the IEC agreed in1994 to com-
bine standardswherever possible
and this led to the ATEX standards
being almost identical to the IEC
standards. There are however some
differences and the harmoniza-
tion process is still on going. The
IEC standards are frequently being
adopted by national approval agen-
cies such asNEPSI inChina.
Thismakes going local approvals
easier.No single, internationally
recognized and accepted standard
exists at this time.Global agen-
cies are committed to harmonizing
standards, but itwill be a long time
before this becomes a reality.
This iswhyMETTLER TOLEDO
uses local approvalswhere neces-
sary to ensure local compliance.
North America
InNorth America (US/Canada) the
regulations related tomanufactur-
ing facilities at risk are found in
theNational Electrical Code (NEC)
Handbook. There are two classifica-
tion systems one based on Class/
Divisions and the other based on
Zones.
Themost common hazardous area
classification system inUS is the
Class/Division is defined in the
NEC500 article. According toNEC
500 hazardous locations are
divided into Substance Classes I,
II, and III depending on the type of
material present. Classes are fur-
ther categorized intoDivision 1 and
Division2 according to the prob-
ability of the hazardousmaterials
present in the ignitable concentra-
tions. The second alternative sys-
tem classification inNorth America
is the Zone classification based on
the IEC / CENELEC guidlines and
defined in theNEC505 article. The
article classified areas into three
Zonesrather than 2Divisions. The
zoning system is however applies
to gas and vapor hazardsonly.
Substance Division
Class I
Gases
Vapors
Division1 Areas inwhich dangerous concentrations of flammable gases/vapors are present
continouslyoroccasionallyunder normal operating conditions.
Division2 Areas inwhich dangerous concentrations of flammable gases/vapors arenotlikely
to be present under normal operating conditions.
Class II
Dusts
Division 1 Areas inwhich dangerous concentrations of flammable dusts are presentcontinuously
oroccasionallyunder normal operating conditions.
Division2 Areas inwhich dangerous concentrations of flammable dusts arenot likely to be present
under nomal operating conditions.
Class III
Fibers
Flyings
Division 1 Areas inwhich dangerous concentrations of flammable fibers and flyings are present
continuouslyoroccasionallyunder normal operating conditions.
Division 2 Areas inwhich dangerous concentrations of flammable fibers and flyings arenot likely to
be present under normal operating conditions.

Compact draft shield
The sliding doors are easy
to open and allow free access
to theweighing chamber as
well as convenient cleaning.
The doors never project
beyond the back of the balance,
which saves valuable space.
Bluetooth
Connect your balancewirelessly,
up to10m from the balance, to
for example a computer and/or a
printer installed in a safe area.
Safe Area Uncompromised Safety and Efficiency
in Hazardous Areas
Touch screen display
Operation intuitive, fast and
convenient. XS Ex2 offers
graphical user guidancewith
alphanumeric keypad.
Stand-alone platform
Available in three sizes, the X platform is
the perfect solution for direct integration into
automated systems. X platforms can be
usedwithout any terminal or togetherwith
the industrial IND4xx or IND690 terminals
through the MT-SICS commands.
ErgoSens
Freely placeable and individually configurable,
the ErgoSens enables hands-free operation of the balance.
Built-in application
Choose between the7 built-in applications:
weighing, statistics, formulation, percent
weighing, piece counting, density determina-
tion and dynamicweighing
