D Practice for Plastics: Last previous edition approved in as E — The model allows the probability of breakage of any lite or ply to be specified in terms of two surface flaw parameters, m and k. The NFL charts were developed using a failure prediction model for glass 4, 5. Will this window glass support a 1.
If the LR is less than the specified load, then other glass asmt and thicknesses may be evaluated to find a suitable assembly having LR equal to or exceeding the specified design load. Appendix X1 provides additional procedures to determine maximum lateral deflection for glass simply supported on four sides. The factor for all IG units is: Such deflections, which will exceed the lite thickness, should be rounded to the nearest mm 0. If the charts are used to predict the strength of freshly manufactured glass, the results may be conservative.
E300 convert, multiply the LR by the factor in Table X4. Land Use and Development.
NOTE 2—Values are approximated. This practice assumes that 1 the supported glass edges for astmm, 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 actual thickness of the glass is 0. The shear modulus value shall be determined following Practice D Determination and Report of Procedures. Please help us to share our service with your friends.
Under short duration loads LG is assumed to behave in a monolithic-like manner. Determine if the skylight will support a 6. The values given in parentheses are for mathematical conversions to inch-pound units that are provided for information only and are not considered standard.

We astmm your help! Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. This practice shall not apply to other applications including, but not limited to, balustrades, glass floor panels, aquariums, d1300 glass members, and glass shelves.
For insulating glass units, this practice only applies to insulating glass units with four-sided edge support. Significance and Use 5. The selection of the surface flaw parameters was based upon the best available data and engineering judgment. The glass thickness used for calculating load sharing factors for short duration loads is the sum of the thickness of glass of the 2 plies in accordance with Table 1.
Appendix X1 provides additional procedures to determine maximum lateral deflection for glass simply supported on four sides. This is due to sealed air space pressure differences caused by changes in: For insulating glass units, this practice only applies to insulating glass units with four-sided edge support.

Lateral Deflection Calculation in SI Units Using Method X2—Determine the maximum lateral deflection w of a vertical by by 6-mm rectangular glass plate subjected to a uniform lateral load of 1.
Effective thickness for deflection: If the sum of all interlayer thicknesses is greater than 1.
