National Electrical Manufacturers Association
provides national testing and
manufac turing standards body of electrical apparatus.
Underwriters Laboratories, Inc.
is an independent testing laboratory. Many
local codes require UL control panels and electrical appa ratus.
Joint Industry Council
is an advisory group that provides standards for
production equip ment, safety, and dependability.
National Fire Protection Association
is the ruling board of NEC and sets national
fire and safe ty standards for equipment and manufacturing facilities.
Canadian Standards Association
is a regulatory agency of Canada.
American National Standards Institute
oversees the creation, promulgation, and

American Society of Mechanical Engineers
is a leader in technical innovation
with a focus on advancing and applying engineering knowledge and
communicating the excitement of engineering. This group is the Secretariat
for ANSI.
National Electrical Code
is an advisory board to NFPA with recommendations
and codes usually adopted throughout the United States.
NEMA 12 classification is to be used in a general purpose, indoor only
application.
All PFlow Industries, Inc. control systems are built to a NEMA 12 minimum
classification. All PFlow Industries, Inc. control systems conform to the
following standards:
z
NFPA 70 (NEC):
The National Electrical Code.
z
NFPA 79:
Electrical standard for industrial machinery.
Outdoor equipment or electrical devices exposed to severe weather conditions
should not be rated less than NEMA type 4. This is a watertight, dust-tight,
indoor-outdoor classification that will provide protection against splashing
water, seep age of water, falling or hose-directed water, and severe external
condensation.
The chemical industry on the whole usually specifies a minimum NEMA type
4X. A NEMA 4X rating is similar to a NEMA 4 with added cor rosion resistance.
