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:
“Perhaps it is the lowest of the qualities of an orator, but it is, on so many occasions, of chief importance,—a certain robust and radiant physical health; or—shall I say?—great volumes of animal heat.”
—Ralph Waldo Emerson (1803–1882)
“The best protection parents can have against the nightmare of a daycare arrangement where someone might hurt their child is to choose a place that encourages parents to drop in at any time and that facilitates communication among parents using the program. If parents are free to drop in and if they exercise this right, it is not likely that adults in that place are behaving in ways that harm children.”
—Gwen Morgan (20th century)
“Biological possibility and desire are not the same as biological need. Women have childbearing equipment. For them to choose not to use the equipment is no more blocking what is instinctive than it is for a man who, muscles or no, chooses not to be a weightlifter.”
—Betty Rollin (b. 1936)
