ASTM E1300-12 PDF

PAGE 1 OF One of the design requirements of glass used in buildings is to resist the loads created by wind and snow. ASTM E to the French and ASTM standard, that in some cases admit a lower design thickness for glass, then for the same . NF P [5] ASTM E – Glass strength evaluation prior to ASTM E Twelve U.S. glass thickness designations were covered from millimetre to millimetre.

NOTE 2—Values are approximated. 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.

D Practice for Plastics: A number in parentheses indicates the year of last reapproval.

Last previous edition approved in as E — Home E – 12ae1 E – 12ae1 September 14, Author: These minimum glass thicknesses are presented in Table 4.

The method applies to 2-ply laminates fabricated from both equal and unequal thickness glass plies. 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. Is someone able to provide some background on this caution statement or point me in the direction of which reference in the Standard I should pursue to get additional information on the caution statement?

Contact the interlayer manufacturer for appropriate shear modulus values. The outboard lite Lite No. For a single monolithic lite with two surfaces equally at risk, p 5 1. Glass99, Thank you, Glass is not one of my normal materials. 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by the responsible technical committee and must be reviewed every five years and if not revised, either reapproved or withdrawn.

Resources Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors. Effective thickness for stress: We need your help!

See Appendix X3 for basis of these values. This method does not apply to glass that has been subjected to severe surface degradation or abuse such as weld splatter or sand blasting. If the charts are used to predict the strength of freshly manufactured glass, aastm results may be conservative.

Complete discussions of the formulation of the model are presented elsewhere 2, 3. Determine if the skylight will support a 6.

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. The maximum allowable stress allowable is a function of area Aload astj in seconds dand probability of breakage Pb. This includes applications where the glass is not supported on one or more edges.

No recommendations are made in asttm practice regarding acceptable lateral deflections. These factors include but are not limited to: Students Click Here Join Us!

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. For insulating glass units, this practice only applies to insulating glass units with four-sided edge support. Thanks for your consideration and time. Work Item s – proposed revisions of this standard. 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 values given in parentheses are for mathematical conversions to inch-pound units that are provided for information asym and are not considered standard.

The information in this practice applies only to polyvinyl butyral PVB interlayer or those interlayers that demonstrate equivalency according to Appendix X8. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility.

The windows are being checked for wind loads only. 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.
