These minimum glass thicknesses are presented in Table 4. A web subscription provides an easy and secure access to standards, and you are guaranteed to always have the latest edition.

Polished Edges, MPa psi Interlayers comprised of differing polymers in multiple layers are not covered in astmm procedure. Originally approved in If the sum of all interlayer thicknesses is greater than 1. If the maximum lateral deflection falls outside the charts in Annex A1, then use the procedures outlined in Appendix X1.

Use the following equation to calculate the equivalent 3-s duration design load: We are a non-profit group that run this website to share documents.
Interlayer samples shall experience full laminating thermal history prior to measurement. Summary of Practice 4. These effective 12qe1 values can be used with standard engineering formulae or finite element methods for calculating both deflection and glass stress of laminates subjected to load. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
NOTE 2—Values are approximated. Long Duration Load 30 days. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. The beam is fixed along one long edge cantilever and is subjected to a line load, P, of 0.
Appendix X1 provides additional procedures to determine maximum lateral deflection for glass simply supported on four sides. 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 proposed laminate construction is 10 mm glass 1. Register for a trial account. As the area of glass under a given stress increases there is an increased risk of breakage occurring.
This maximum calculated stress must be less than the maximum allowable stress. If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee atsm Standards, at the address shown below. Appendix X1 provides additional procedures to determine maximum lateral deflection for glass simply supported on four sides. Webprint Printed and bound. Short Duration Load 3 s.
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 greater the shear resistances, the more effectively the two glass plies couple and resist deformation under loading. Home E – 12ae1 E – 12ae1 September 14, Author: Long Duration Load 30 days. If you like to setup a quick demo, let us know at support madcad.
Note 1 This practice does not address aesthetic issues caused by glass deflection. The actual thickness of the glass is 0. Read more about subscriptions.
If the LR is less than the specified load, then other glass types and thicknesses may be evaluated to find a suitable assembly having LR equal to or exceeding the specified e1300 load. 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.
Land Use and Development.
The information in this practice applies only to polyvinyl butyral PVB interlayer or those interlayers that demonstrate equivalency according to Appendix X8. Print 1 2 3 4 5 page sstarting from page current page. Thank you for interesting in our services.
This includes trapezoids, circular, triangular, and other odd shapes. The specified design load shall be used for this calculation. Current edition approved May 1, This standard is subject to revision at any time by the responsible technical committee and must be reviewed every five years and if not revised, either reapproved or withdrawn. A conservative allowable surface stress value for a 3-s duration load is 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 The model allows the probability of breakage of any lite or ply to be specified in terms of asfm surface flaw parameters, m and k.
