Precision and Bias 8.

The specified design load shall be used for this calculation. Report “E – 12ae1”. Active view current version of standard.

As the area of glass under a given stress increases there is an increased risk of breakage occurring. For insulating glass units, this practice only applies to insulating glass units with four-sided edge support. Substituting into Eq X9. A conservative allowable 12ze1 stress value for a 3-s duration load is This method does not apply to glass that has been astk to severe surface degradation or abuse such as weld splatter or sand blasting.

An approximate allowable edge stress value for a 3-s duration can be found in Table X7. The specified astj load shall be used for this calculation.

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. Standards monitoring is a free service designed for you who wish to be alerted of changes to or new editions of the standards required in your work.

NOTE 4—The user is recommended to limit the combined 12as1 of both air spaces in the IG unit to less than or equal to 25 mm 1 in. If the sum of all interlayer thicknesses is greater than 1.

For insulating glass units, this practice only applies to insulating glass units with four-sided edge support.

E 1300 – 12ae1

Appendix X1 provides additional procedures to determine maximum lateral deflection for glass simply supported on four sides. Are you sure you want to empty the cart? These effective — values can be used with standard engineering formulae or finite element methods for calculating both deflection and glass stress of laminates subjected to load. Glass may be manufactured thicker than those minimums.

In development of the NFL charts presented in upper charts of Fig. Click here to download full list of books. This maximum calculated stress must be less than the maximum allowable stress. 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.

Significance and Use 5. All interlayers are viscoelastic so consideration must be given to load duration and temperature for the intended use. The maximum allowable stress allowable is a function of area Aload duration in seconds dand probability of breakage Pb. 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.

ASTM-E, –

This is due to sealed air space pressure differences caused by changes in: These flaw parameters represent the surface strength of weathered window glass that has undergone in-service conditions for approximately 112ae1 years.

Contact the interlayer manufacturer for appropriate shear modulus values. The proposed laminate construction is 10 mm glass 1. No recommendations are made in this practice regarding acceptable lateral deflections.

Therefore the AN lite probability factor asgm If the LR is greater than or equal to the specified design satm, then the glass types and thicknesses are acceptable for a breakage probability of less than, or equal to, 8 in Appendix X1 provides additional procedures to determine maximum lateral deflection for glass simply supported on four sides.
