Voluntary Standards Cover the Spectrum: From Soda Machines to Dental Fillings

New York, Nov 19, 2002

In an effort to communicate the vital role that standards play in daily life, ANSI Online News will publish, on an ongoing basis, 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:

Soda Machines

In the early 1920's a mystical machine was invented that could dispense gallons of fizzy liquid caffeine into cups, and soon became fondly known as a soda fountain. Though the nostalgia of the soda fountain has faded, many of us still need our daily "jolt" of soda to get us through the day. In fact, it is estimated that seventy million gallons of the "liquid candy" is consumed each day worldwide.

To improve on this nearly 90-year old invention, the American Society of Heating, Refrigerating and Air-Conditioning Engineers, Inc. (ASHRAE), an ANSI member and ANSI-accredited standards developer, recently published the draft revision, BSR/ASHRAE 32.2-200x, Methods of Testing for Rating Pre-Mix and Post-Mix Beverage Dispensing Equipment. The standard prescribes a uniform method for testing and rating the capacity and efficiency of pre-mix and post-mix beverage vending machines. Due to changes in the industry, the scope of the standard was redesigned to be more specific to include equipment types that are currently appearing on the market and exclude those that have disappeared from the market. The new standard will replace an earlier American National Standard, ANSI/ASHRAE 32.2-1997 Methods of Testing Pre-Mix and Post-Mix Soft Drink Vending and Dispensing Equipment published in 1997.

Dental Fillings

The treatment of dental cavities goes back centuries, but it was not until 1875 that the type of treatment used today was created. Dr V. Black discovered that removing the decayed part of the tooth (the cavity) and replacing it with silver (amalgam) fillings could help prevent further decay. Today, according to the Center for Disease Control, nearly 80% of all American children have had or currently have fillings due to high intakes of candy, sugar frosted breakfast cereals, ice cream, and especially soda. In use for over 125 years, silver fillings are the most popular, with over 1 billion restorations placed each year.

The American Dental Association (ADA), an ANSI member and ANSI-accredited standards developer, recently published the draft revision BSR/ADA 1-200x, Alloy for Dental Amalgam. This new standard creates specifications for alloys, composed mainly of silver, tin and/or copper, used in the preparation of dental amalgam. Only capsulated alloy is covered under this specification. The standard is currently in development and will be under public review until December 30. By improving this standard, dental amalgam becomes easier for dentists to work with and safer for patients.
