ICC Releases 2004 Supplement to 2003 Codes; Adopts Labeling Systems
The International Code Council (ICC) has released the 2004 supplement to the 2003 International Codes. The supplement contains the latest developments in building regulations since the publication of the 2003 I-Codes. 
According to a news release from the ICC, changes have affected the International Building Code (IBC), International Residential Code, International Fire Code and the International Energy Conservation Code (IECC), among others. 

Following publication of the 2003 I-Codes, the ICC called for code change proposals to begin the next I-Code development cycle. Staff compiled the proposals into a monograph of proposed changes, convened code development hearings and then published the report of the public hearings. Public comments on those hearings were published in the final action agenda before the final action hearings. 

The 2004 supplement contains the changes submitted in the 2003/2004 code development cycle that were approved by the voting membership of the ICC.

The following changes to the IBC deal with glass and glazing:
• FS15: Will re-organize the code sections related to fire-protected openings for clarity;
• FS78 and FS80: Now requires specific identification of fire-protection-rated glazing;
• S84: Includes a complete revision of structural provisions to bring the code into agreement with ASTM E1300-02. The technical changes include a shift from 60 second, non-factored load charts to three-second charts (to be consistent with ASCE-7). Factor tables have been deleted from the code since they are included in ASTM E1300;
• S86: Now includes a reference to laser labeling as an acceptable means of labeling glazing; 
• S88: The entire section regarding glass in floors and sidewalks has been removed. This means the prescribed design methodology that was contained in the code cannot be used in designing glass in floors and sidewalks; it means a more rigorous design method must be employed; and
• S85: Limits the use of wired glass in all building structures in areas subject to human impact.
Regarding the IECC, the EC31 code change was also approved. It establishes criteria for factory-assembled and site-built fenestration products and establishes climate zone criteria for U-factors in regards to these products. 

In addition, the ICC has adopted a labeling system introduced by Pilkington that is designed to help building code officials recognize both performance characteristics and appropriate applications for any number of the new fire-rated glazing materials on the market.

According to the IBC, different performance characteristics for fire-rated glazing are specified depending on whether used as a wall, an opening in a wall or a door. These three criteria are the basis for Pilkington’s system.
• If a glazing meets the fire, temperature rise and hose-stream testing specified in ASTM E119 for a fire-rated wall, glazing will be labeled with a “W,” followed by the time in minutes of its fire resistance;
• If a glazing meets the fire and hose-stream testing specified in NFPA 257 for “opening” protectives, the glazing will be labeled with an “OH” for “opening and “hose-stream” tested, followed by the time in minutes of its fire-protection rating; and
• If a glazing meets the fire-testing specified in NFPA 252 for a “door,” it is labeled with a “D.” Glazing used in fire doors, according to the release, “warrants a slightly more complicated label than other applications” for a couple of reasons. For one, 20-minute doors, including the glazings in them, do not need to meet the hose-stream test, when other protective openings do. Secondly, some doors limit temperature rises to 450 degrees Fahrenheit during the first 30 minutes of the fire test. Therefore, to address these requirements, the new labeling system also adds an “H” designation if the glazing in a door does meet the hose stream test or an “NH” if it does not. In addition, it adds a “T” if the glazing can meet the temperature rise limitation and an “NT” if it cannot. The time in minutes that the glazing is fire rated is also included on the label.

The labeling requirements are included as part of the 2003 IBC Supplement.

ASTM Standard for Glass Rails Completes Development Process
The first version of an ASTM International standard for glass rails, titled Standard Test Method for the Performance of Glass in Permanent Glass Railing Systems, Guards and Balusters, has completed the development process. 

The standard’s ASTM number is E2353-04 and it will be included in the 2004 ASTM Book of Standards.
“It is widely recognized that the introduction of new standard test methods usually takes time for widespread acceptance, and for the most part it is always a step forward in the quality of products being provided,” said Solutia’s Julie Schimmelpenningh who also serves as the ASTM subcommittee chairperson for E06.56 Performance of Railing Systems and Rails for Buildings. “When you can test and compare performance on an apples-to-apples basis using an industry consensus document, it provides a level of confidence to the end-use customer. The test method, which will shortly be followed by a specification, should provide that baseline in the performance testing of glass rails.”

Ohio Changes Auto Tint Law
As of April 8, 2004, the back windshields (including rear passenger sidelites and backlites) of cars in Ohio may be tinted to the discretion of the vehicle owner. Under the changed law, driver and front passenger side door windows can be tinted up to 50 percent light reduction; any windows further back on the car may be as dark as the owner wishes, provided the car is equipped with two side-view mirrors (one on each front door) so that drivers can see the road behind them. The front windshield must remain at 30 percent.

ASTM Optical Properties Subcommittee Formed
The executive subcommittee of the ASTM C14 committee has approved the formation of subcommittee C14.11 on optical properties. The scope of the subcommittee is to develop test methods, guides and specifications relating to the measurement of the optical properties of glass. Alex Redner of Strainoptics Inc. will serve as the subcommittee chairperson. 

In addition, ASTM C14.08 flat glass subcommittee chairperson Rick Wright, of Oldcastle Glass, recently formed a new task group, ASTM C1036-01, to review, revise and update the standard specification for flat glass. Michael Bitterice, of PPG Industries Inc., will serve as the chairperson of the new task group. The group expects that the revised standard will be balloted in 2006. 

briefly ...
ASTM International’s committee E06 on the performance of buildings has established a new subcommittee, E06.77, on high-rise building external evacuation devices. The committee will meet in October to look at the development and maintenance of standards for buildings’ multiple-occupant (10 or more) evacuation devices.
