Voluntary Standards Cover the Spectrum: from Toilet Seats to Pressurized Enclosures


New York, Jun 25, 2013

In an effort to communicate the vital role that standards play in daily life, the American National Standards Institute (ANSI) publishes a series of 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:

Plastic Toilet Seats
Toilets may be an unglamorous topic, but the average person visits the loo, lavatory, water closet, latrine, or restroom approximately seven times a day – that's more than 2,500 times a year. During these visits, users encounter toilet seats of various shapes and materials: oval, round, padded, heated, glass, polymer, wooden, and plastic.

To ensure plastic toilets seats are manufactured for safe and sanitary use a new American National Standard (ANS) was recently released by the International Association of Plumbing and Mechanical Officials (IAPMO). IAPMO/ANSI Z124.5-2013, Plastic Toilet Seats, covers both plastic toilet seats and toilet seat covers, and specifies requirements for materials, construction, performance testing, and markings.

IAPMO, an ANSI organizational member and audited designator, is a non-profit membership organization for the plumbing and mechanical industry that works in concert with government to develop safe and sustainable codes, advance product certification, and foster education worldwide, while protecting consumer health and supporting emerging technologies.

Pressurized Enclosures
Many electronics systems, including electrical equipment, motors, and switchgears, require the air within the apparatus to be free of all dust and gases to ensure safe and proper performance. To achieve clean air within the atmosphere of a potentially flammable electrical apparatus, the technique of pressurizing and purging is used. In an effort to provide guidance to those who employ pressurization for electrical equipment in hazardous locations by use of a pressurizing system, the International Society of Automation (ISA) recently published ANSI/ISA 12.04.04-2012, Pressurized Enclosures.

ANSI/ISA 12.04.04-2012 provides performance and test recommendations so that the enclosure and components mounted internally or protruding through the enclosure are unlikely to cause ignition of a surrounding flammable atmosphere, as well as recommendations so that users are unlikely to be injured by rupture of the enclosure due to failure of the pressure-regulating devices in the protective gas supply. ISA recommends ANSI/ISA 12.04.04-2012 be used in conjunction with NFPA 496-2013, Standard for Purged and Pressurized Enclosures for Electrical Equipment.

An ANSI organizational member and accredited standards developer, ISA is a global non-profit organization that develops standards, certifies industry professionals, provides education and training, publishes books and technical articles, and hosts conferences and exhibitions for automation professionals.
