For insulating glass units, this practice only applies to insulating glass units with four-sided edge support. For conversion of quantities in various systems of measurements to SI units, refer to SI The values given astm e1300 parentheses are astm e1300 information only. Determination and Report of Procedures. Invalid Email Address Message: Determination and Report of Procedures. The procedures operate under some basic assumptions related to glass fabrication and installation, including:.
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 resulting load resistance, which is the uniform load that a glass construction can sustain without breaking.
Tempered glass deflects just as much as annealed glass. These factors include but are not limited to: This practice assumes that 1 the supported glass edges for two, three, and four-sided support conditions are simply supported astm e1300 free to astm e1300 in plane; 2 glass supported on two sides acts as a simply supported beam; and 3 glass supported on one astm e1300 acts as a cantilever.
astm e1300 The glass type factor, which is the multiplying factor for adjusting the load resistance of different glass types. The astm e1300 given in parentheses are for mathematical conversions to inch-pound units axtm are provided for information only and are not considered standard.
Designing Glass to Resist Wind and Snow Loads
It astm e1300 the responsibility of the user of this standard to establish appropriate safety and health astm e1300 and determine the applicability of regulatory limitations prior to use. D Practice for Plastics: Glass Education Center The single source for information on designing, specifying and building with commercial glass.
Start with the glass dimensions and the specified design loading. Appendix X1 provides additional procedures to determine maximum lateral deflection for glass simply supported on four sides. If the load resistance is less than the specified design loading, or if the center of glass deflection is excessive, then the trial design needs to be modified and astm e1300. D Practice for Plastics: This practice does not apply to glass with surface or edge treatments that reduce the glass strength.
However, some applications can be two-sided support, such as Butt Joint Glazing or sometimes even three-sided or one-sided supports. Link to Active This link will e1300 route to the current Active version of the standard.
How much does glass weigh? Related posts you may also enjoy. Astm e1300 you see condensation on the outside of your low-e glass windows, it means the coating e130 working properly.
Thermal or insulation improvements achieved with an IGU work day and night in both summer and winter conditions, reducing heat entry and astm e1300 loss. Glass deflections are to be reviewed.
Basic Astn Procedures The assumptions astm e1300 calculations result astm e1300 these basic design procedures that should be followed: The final thickness and type of glass selected also depends upon a variety of other factors see 5.
Insulated glass units or double glazed units are a significantly more energy efficient glazing system than single glazing.
ASTM E – 16 Standard Practice for Determining Load Resistance of Glass in Buildings
Glass 6mm thick will weigh 2. 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.
The specified design astm e1300, which is the magnitude in kPa or PSF, of the type and duration of the load that is specified by the building code. Pure glass is incredibly strong astm e1300 it only scratches or breaks because of imperfections that can occur during the manufacturing process.
It also weighs astm e1300 same. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Appendix X3 presents astm e1300 procedure to compute approximate probability of breakage for annealed AN monolithic glass lites simply supported on four sides. The thermal barrier makes interior spaces more comfortable as it is easier to maintain a consistent indoor environment. The number of glass edges supported. If astm e1300 load resistance is astm e1300 than the specified design loading and the center of glass deflection is reasonable, then the trial design is fine and can proceed.
The specified design load shall be used for this calculation. This practice astm e1300 not consider astm e1300 effects of deflection on insulating glass unit seal performance. The procedures operate under some basic assumptions related to glass fabrication and installation, including: Accommodating for wind and snow is one of the important upfront considerations in the design and specification process.
