Other Standard/Specification Significant Changes
In addition to the specific changes noted, the following revisions have been included in the new standard/specification:
- The expansion of the product rating system to provide a primary designator similar to that in current use and a new secondary designator that allows reporting of performance criteria such as negative design pressures, water penetration resistance test pressures, and optional performance tests;
- Revision of gateway requirements to an SI (metric) basis, while still maintaining the inch-pound (psf) nominal rating intervals common to previous standards/specifications;
- The increase in the number of product operator types from 26 to 30 (Table 2);
- The addition of Canadian air infiltration/exfiltration levels and operating force requirements;
- The revision to U.S. operating force requirements to initiate motion to �Report Only�;
- Updated glass strength standard, as the basis for glass selection, to ASTM E 1300-02;
- Introduction of cycle/operation testing for side-hinged doors;
- Introduction of hardware water testing, vertical load, and forced entry resistance testing for doors;
- Addition of numerous new sash, frame, and glazing material requirements;
- Elimination of the words residential, light commercial, heavy commercial, and architectural from the performance class definition and their replacement by the simple designations R, LC, C, HC, and AW;
- The addition of six new requirements for plastic glazing;
- Skylight structural test load changed from 1.5 times design pressure positive, 2.0 times design pressure negative to 2.0 times design pressure both positive and negative;
- Specimen structural damage limiting retests due to glass breakage or hardware failure to two; and
- Finished framing and cladding materials not allowed to contain more than 0.02 percent lead by weight.
