Start Webshop Product catalog Product presentation. Interlayer samples shall experience full laminating thermal history prior to measurement. For aspect ratios greater than 5, use 5. 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. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.
These effective thickness values can be used with standard engineering formulae or finite element methods for calculating both deflection and glass stress of laminates subjected to load. Therefore the LR of the IG is: 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.
If the sum of all interlayer thicknesses is greater than 1. F Standard Specification for Driven Fasteners: Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.
If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below.
E 1300 – 12ae1
The NFL is thus found to be 2. No items in cart. Significance and Use 5.
D Practice for Plastics: There were no books found for the applied search filters. Appendix X1 provides additional procedures to determine maximum lateral deflection for glass simply supported on four sides. This is due to sealed air 12aw1 pressure differences caused by changes in: The values given in parentheses are for mathematical conversions to inch-pound units that are provided for information only and are asrm considered standard. Significance and Use 5.

Appendix X1 provides additional procedures to determine maximum lateral deflection for glass simply supported on four sides.
ASTM E – 12ae1 Standard Practice for Determining Load Resistance of Glass in Buildings
This service is not available if you are a URL user where you do not log in with an email address. Rigorous engineering analysis that accounts for the geometrically nonlinear performance of glass lites, glass surface condition, residual surface compression, surface area under stress, geometry, support conditions, load type and duration, and other relevant parameters can result in other type factors.
Today, some 12, ASTM standards are used around the world to improve product quality, enhance safety, facilitate market access and trade, and build consumer confidence. If the LR is less than the specified load, then other glass types and thicknesses may be evaluated to atsm a suitable assembly having LR equal to or exceeding the specified design load.
For these loading duration and temperature considerations the interlayer shear modulus, G, is determined to be 0. If the LR is greater than or equal to the specified design load, then the glass types and thicknesses are acceptable for a breakage probability of less than, or equal to, 8 in If the maximum lateral deflection falls outside the charts in Annex A1, then use the procedures outlined inAppendix X1.

The method applies to 2-ply laminates fabricated from both equal and unequal thickness glass plies. NOTE 1—This practice does not address aesthetic issues caused by glass deflection. Enter your account email address to request a password reset: The outboard lite Lite No. The final thickness and type of glass selected also depends upon a variety of other factors see 5.
The specified design load shall be 122ae1 for this calculation.
The selection of the surface 12ze1 parameters was based upon the best available data and engineering judgment. If the charts are used to predict the strength of freshly manufactured glass, the results may be conservative. Contact the interlayer manufacturer for appropriate shear modulus values. For glass simply supported on three sides, the ratio of the length of one of the supported edges perpendicular to the free edge, to the length of the free edge, is equal to or greater than 0.
A conservative allowable surface stress value for a 3-s duration load is For insulating glass units, this practice only applies asmt insulating glass units with four-sided edge support. The values given in parentheses are for mathematical conversions to inch-pound units that are provided for information only and are not considered standard. For insulating glass units, this practice only applies to insulating glass units with four-sided edge support.
The specified design load shall be used for this calculation.
