ASTM Standards:2 This practice applies only to monolithic, laminated, or C Specification for Flat Glass insulating glass constructions of rectangular. ASTM E • Provides a conservative glass thickness procedure. ▫ Flat Glass Plates. ▫ Uniform Pressure Loads. • All publicized problems with HS ceramic. a result, some glass sizes may meet ASTM E for a given wind load but not be acceptable due to safety and manufacturing concerns. Note these tables are.

The resulting load resistance, which is the uniform load that a glass construction can sustain without breaking. About The Education Center Resources.

Insulated Glass Units are made with two or more lites of glass with a hermetically sealed space filled with dry air or insulating gas. Specifying Large Insulated Glass Units. In addition, considerations set forth in building codes along with criteria presented in safety-glazing standards and site-specific concerns may control the ultimate glass type and thickness selection. The procedures operate aastm some basic assumptions related to glass fabrication and installation, including: Appendix X3 presents a procedure to compute approximate probability of breakage for annealed AN monolithic glass lites simply supported on four sides.

The load share factor, which is the multiplying factor derived from the load sharing between two lites of equal or different types or thicknesses. Determination and Report of Procedures. This practice assumes that 1 the supported glass edges for two, three, and four-sided support conditions are simply supported and free to slip in plane; 2 glass supported on two sides acts as a simply supported beam; and 3 glass supported on one side acts as a cantilever.

ASTM E – 09 Standard Practice for Determining Load Resistance of Glass in Buildings

The relative strength of glass for a given thickness, width, height and number of supported edges. Glass deflections are to be reviewed. The surface condition of the glass doesn’t have any significant damage.

The number of glass edges supported. Related posts you may also enjoy. This practice does not consider the effects of deflection on insulating glass unit seal performance.

Thermal or insulation improvements achieved with an IGU work day and night in both summer and winter conditions, reducing heat entry and heat loss.

Glass 6mm thick will weigh 2. The specified design load, which is the magnitude in kPa or PSF, of the type and duration of the ast, that is specified by the building code.

If the load resistance is greater than the specified design loading and the center of glass deflection is reasonable, then the trial design is fine and can proceed. The word window comes from a Norse term translated “wind eye”, for “eye on the weather.

D Practice for Plastics: IGUs reduce sound transmission and provide quieter interior spaces. For example, orange, red, yellow and violet colored glasses cannot be produced using standard float technology. Start with the glass dimensions and the specified design loading. D Practice for Plastics: About The Education Center.

Monolithic, laminated and insulating glass constructions made with annealed or heat-treated glass. Satm final thickness and type of glass selected also depends upon a variety of other factors see 5. Active view current version of standard. Pure glass is incredibly strong — it only scratches or breaks because of imperfections that can occur during the manufacturing process.

The specified design load shall be used for this calculation.

Designing Glass to Resist Wind and Snow Loads

Designing Glass aztm Resist Wind and Snow Loads Accommodating for wind and snow is one of the important upfront considerations in the design and specification process. The final thickness and type of glass selected also depends upon a variety of other factors see 5. The assumptions and calculations result in these basic design procedures that should be followed:.

Tempered glass deflects just as much as annealed glass. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

The glass has been properly glazed, without any edge damage. If you see condensation on the outside of your low-e glass windows, it means the coating is working properly. The glass type factor, which is the multiplying factor for adjusting the load resistance of different glass types.

This practice does not address aesthetic issues caused by glass deflection. Glass Education Center The single source for information on designing, specifying and building with commercial glass. It also weighs the same. This practice shall not apply to other applications including, but not limited to, balustrades, glass floor panels, aquariums, structural glass members, and glass shelves. However, some applications can be two-sided support, such as Butt Joint Glazing or sometimes even three-sided or one-sided supports.

Short and long duration uniform loads. The procedures operate under some basic assumptions related to glass fabrication and installation, including:.

Due to the chemistry involved in the float glass process, all the colors of the rainbow are not possible.

For insulating glass units, this practice only applies to insulating glass units with four-sided edge support.
