Standard Organizations

National Electrical Manufacturers' Association

• NEMA or “TYPE” is recognized within North America.
• There is no lab-testing required for NEMA. Compliance and testing are the responsibility of the enclosure manufacturer.
• NEMA does not provide “certification labels” for enclosures.

Common NEMA Types:

• NEMA 12 (dust)
• NEMA 4 (water tight)
• NEMA 4X (water & corrosion protection)

NOTE: Open style networks racks cannot have a NEMA rating

• NEMA Standards Publication No. 250 enclosures for Electrical Equipment (1000 Maximum)
• NEMA Standards Publication No. ICS6 enclosures for Industrial Controls and Systems

Underwriters' Laboratories Inc.

UL Requires that enclosures be tested in an approved lab in order to prove their performance.

• UL 50 Cabinets and Boxes
• UL 2416 Data/Comm Equipment Cabinets

CSA International

Requires that enclosures be tested in an approved lab in order to prove their performance.
Note: CSA is not applicable to network rack/cabinets.

• CSA Standard C22.2, No 0.4 Bonding and Grounding of Electrical Equipment 
  (Protective Equipment)
• CSA Standard C22.2, No. 14 Industrial Control Equipment for Use in Ordinary
  (Non-Hazardous) Locations
• CSA Standard C22.2, No. 94-M91 Special Purpose Enclosures

International Building Code (IBC)

California Building Code (CBC)

National Building Code of Canada (NBC)

• Requires that rack or cabinet be tested by a Structural Engineer to prove the performance.
• Requires analytical calculations.
• Does not involve a physical test.

Erricsson - Telcordia (Previously Bellcore)

• NEBS GR-63-CORE Seismic
• Requires that rack or cabinet be physically tested in a lab for vibrations and physical movement (shaker table), simulating an earthquake to prove performance.

Payment Card Industry Security Standards Council (PCI SSC)

• The council was founded in 2007 by several global credit card companies.
• The standard helps to ensure the security of credit card transactions in the payment industry.
• PCI compliance may be required where credit card processing is facilitated.

Electronic Industries Association (EIA)

• EIA/ECA-310 revision E, is a specification for what is often called the “standard rack”. This specification standardizes several important features of 19″ racks, such as the rack unit (RU or U), vertical hole spacing, horizontal hole spacing, rack opening and front panel width.
• The specification also sets tolerances on each of these dimensions.

Conformitè Europëenne (CE)

• The CE marking represents a manufacturer’s declaration that products comply with the EU’s New Approach Directives.
• These directives not only apply to products within the EU but also for products that are manufactured in or designed to be sold in the European Economic Area (EEA).

American National Standards Institute (ANSI)

• The American National Standards Institute (ANSI) is a private, non-profit organization that administers and coordinates the U.S. voluntary standards and conformity assessment system. Founded in 1918, the Institute works in close collaboration with stakeholders from industry and government to identify and develop standards- and conformance-based solutions to national and global priorities.

Restriction of Hazardous Substances in Electrical and Electronic Equipment (RoHS)

RoHS was implemented in 2003 to prevent the release of harmful substances during the use, collection, treatment and disposal of electronic waste. These substances can and are known to cause major environmental and health problems.

To comply with RoHS a manufacturer must restrict the use of using the following hazardous substances in the manufacturing of electrical and electronic components:

• Lead
• Cadmium
• Mercury
• Hexavalent chromium
• Polybrominated biphenyls (PBB)
• Polybrominated diphenyl ethers (PBDE)
• Bis(2-ethylhexyl) phthalate (DEHP)
• Butyl benzyl phthalate (BBP)
• Dibutyl phthalate (DBP)
• Diisobutyl phthalate (DIBP)
