Voluntary Standards Cover the Spectrum: from Telecommunications Enclosures to Door Closers


In an effort to communicate the vital role that standards play in daily life, the American National Standards Institute (ANSI) publishes snapshots of the diverse standards initiatives undertaken in the global and national standards arena, many of which are performed by ANSI members and ANSI-accredited standards developers. Two of the latest selections follow:

Telecommunications Enclosures
Electrical and telecommunications equipment can cause bodily harm if left out in the open. To protect workers and the public, and to prolong the lifecycle of the equipment, enclosures surround transformers and other electrical apparatus. A recently revised American National Standards (ANS) from the Society of Cable Telecommunications Engineers (SCTE) has been published to ensure underground telecommunications enclosures have the proper support, ventilation, access for installation and servicing of the equipment, security against tampering or entry by unauthorized persons, and safety against electrical shock or other injury.

ANSI/SCTE 77 2013, Specification for Underground Enclosure Integrity, covers conformance tests and requirements for the integrity of grade-level enclosures containing telecommunications or other low-voltage apparatus that may be exposed to the public. Revisions to the new edition of more clearly define and extend testing procedures for de-icing solutions, light exposure, control values for load and deflection, and lateral sidewall pressures.

SCTE, an ANSI member and accredited standards developer, is a non-profit professional association that provides technical leadership for the telecommunications industry, serving its members through professional development, standards, certification, and information.

Door Closers
Commonly going unnoticed, a door closer is a mechanical device that closes a door automatically after being opened. It helps to ensure proper functioning of the door and protects users entering or exiting buildings. A recently published ANS from the Builders Hardware Manufacturers Association (BHMA) provides guidelines for the proper installation of door closers.

ANSI/BHMA A156.4-2013, Door Controls – Closers, contains cycle, operational, closing force, and finish tests as criteria for conformance. The standard covers requirements for door closers that are surface mounted, concealed in the door, overhead concealed, and concealed in the floor, and also includes requirements for floor closer pivots.

BHMA, an ANSI member and accredited standards developer, is a trade association for North American manufacturers of commercial builders hardware. In addition to developing and updating safety standards for architectural hardware, BHMA advocates for industry before commerce, trade, and regulatory bodies; sponsors third-party certification of builders hardware products; and offers technical expertise before key building code, fire, and life safety groups.
