GANA Mirror Division Promotes The Use of Code ASTM C 1503-01

The Glass Association of North America (GANA) mirror division is promoting the use of ASTM C 1503-01 – Standard Specification for Silvered Flat Glass Mirror. The standard covers silver annealed monolithic clear and tinted flat glass mirrors up to ¼-inch thick, supplied as cut sizes, stock sheets or as lehr ends.

According to GANA mirror division national officer Lee Harrison, “This standard is something that people at all levels of the industry have wanted for some time. Now that it is in place, it will be up to specifiers, buyers, fabricators and vendors of mirror to adopt it and utilize it on a daily basis. As more and more companies and individuals use the standard the end result will be a widespread acceptance of the standard and a greater understanding of the product by all involved.”

The standard was developed in order to establish uniform expectations from manufacturing to installation, provide guidelines to specifiers to match products to applications and to provide a benchmark for drafting of contracts, warranties and disclaimers for mirrors, all while protecting the integrity of the industry. 

Texas Adopts New Energy Efficiency Codes

In the most significant change to Texas energy code requirements in the last decade, the state’s legislature has adopted the 2001 International Energy Code Compliance (IECC) as an addition to the state’s energy code. Due to the recent energy crises, in addition to wider availability of energy efficient skylights and windows, the code revisions went into effect September 1, 2001.
 
According to the code revisions, the new plan depends on the number of heat days in each county. The glazing industry will be affected as follows:

• Texas counties average between 1,500 to 3,000 heat degree days; For window area of 12 percent of the gross exterior wall area there is a required glazing U-factor performance of .75 (1,500-1,999 days) and .60 (2,500 to 3,499 days). Dallas will require .60; and Houston .75;

• For window area of 15 percent of the gross exterior wall area, there is a required glazing U-factor performance of .65 (1,500-1,999 days) and a .55 (3,000- 3,499 days). Dallas will require .5; and Houston .75;

• For window area of 18 percent of the gross exterior wall area, there is a required glazing U-factor performance of .65 (1,500-1,999) and .50 (3,000-3,499 days). Dallas will require .50; and Houston .65.

DOD Approves UFC; Citing IBC and NFPA Codes
The Department of Defense (DOD) has approved its Unified Facilities Criteria (UFC). The UFC 1-200-01, Design: General Building Requirements, provide planning, design, construction, operation and maintenance criteria for DOD facilities. According to a news release, the UFC incorporates the International Code Council’s Internat-ional Building Code (IBC), as well as a number of codes from the National Fire Protection Association (NFPA). 

“DOD has been referencing some provisions of the model codes for years, but a lack of a common, national code inhibited our full use of these codes,” said David Curfman, director for the Naval Facilities Engineering Command Engineering Innovation and Criteria office. “Now with a single model code available, we can use the best lessons learned from the private sector and ensure consistent design DOD-wide.”

The UFC 1-200-01 is also utilizing three of the NFPA’s codes. “The [DOD] has been using NFPA codes and standards for years,” said James M. Shannon, NFPA president and chief executive officer. “The United Facilities Criteria continues the military’s use of NFPA documents and will play an important role in the safety of military structures.”

The three NFPA codes in the UFC are NFPA 70, National Electrical Code®, NFPA 54, National Fuel Gas Code and NFPA 101 Life Safety Code®.
