Physical Protection of Equipment
NEBS contains the key industry requirements for how to design and build reliable electronics for telecom network use. It is unique in its focus on telecommunications applications and environments for electronic systems. The proper design, engineering, manufacturing, and workmanship of equipment are critical for long-term use in all environments.
For physical protection, good engineering practices cover metal surface treatment and contact compatibility, flammability ratings, component marking and traceability, electrical and mechanical integrity, and a variety of process manufacturing issues.
The RBOCs often require that detail design selection and implementation take into account the various elements of NEBS GR-78, Generic Requirements for the Physical Design and Manufacture of Telecommunications Products and Equipment
GR-78 has requirements that cover details of design implementation that need to be discussed, reviewed, and implemented, as appropriate, in equipment intended to be NEBS compliant. Topics include, but are not limited to, materials and finishes; electrostatic discharge requirements; printed wiring boards and assemblies; connectors, wire, and cable; product marking and identification; and qualification test procedures. GR-78 also clarifies the industry position on the use of Lead (Pb)-free solder and allows for alternative finishes such as immersion silver, etc.

Famous quotes containing the words physical, protection and/or equipment:
“Life on board a pleasure steamer violates every moral and physical condition of healthy life except fresh air.... It is a guzzling, lounging, gambling, dog’s life. The only alternative to excitement is irritability.”
—George Bernard Shaw (1856–1950)
“Innocence does not find near so much protection as guilt.”
—François, Duc De La Rochefoucauld (1613–1680)
“Dr. Scofield’s equipment, which you have just seen, radiated waves direct to Professor Houghland’s laboratory. When these waves came in contact with those the professor’s equipment was radiating, they created the interstellar frequency, which is the death ray.”
—Joseph O’Donnell, and Clifford Sanforth. Arthur Perry (Bela Lugosi)
