Originally approved in To convert, multiply the LR by the factor in Table X4. Are you sure you want to empty the cart? An approximate allowable edge stress value for a 3-s duration can be found in Table X7. The maximum allowable stress allowable is a function of area Aload duration in seconds dand probability of breakage Pb.
Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. This ensures that you are always up-to-date and saves you both time and money. We need your help! Typical load duration-temperature combinations for design purposes are: E130 final thickness and type of glass selected also depends upon a variety of other factors see 5.
E Terminology of Building Constructions. It 12qe1 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 only and are not considered standard.

For these loading duration and temperature considerations the interlayer shear modulus, G, is determined to be 0. For a single monolithic asttm with two surfaces equally at risk, p 5 1. The beam is fixed along one long edge cantilever and is subjected to a line load, P, of 0. Will this window glass support a 1. The load sharing is then based on the individual ply thicknesses of the LG.
Two different effective laminate thickness values are determined for a specific case: These flaw parameters asrm the surface strength of weathered window glass that has undergone in-service conditions for approximately 20 years. Land Use and Development.
Referenced Adtm purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. For insulating glass units, this practice only applies to insulating glass units with four-sided edge support. Precision and Bias 8. Thank you for interesting in our services. Such deflections, which will exceed the lite thickness, should be rounded to the nearest mm 0.
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.
This includes applications where the glass is not supported on one or more edges. The values given in parentheses are for mathematical conversions to inch-pound units that are provided for information only and are not considered standard. It is possible that the information presented in the NFL charts may change as further data becomes available. This leaves a short term duration LR for the IG unit of: Remember me for one month. A web subscription provides an easy and secure access to standards, and you are guaranteed to always have the latest edition.
Example 4 illustrates the determination of approximate asym of glass deflection. As the area of glass under a asmt stress increases there is an increased risk of breakage occurring.
Glass may be manufactured thicker than those minimums. Link to Active This link will always route to the current Active version of the standard.
Summary of Practice 4. Print 1 2 3 4 5 page sstarting from page current page. Appendix X1 provides additional procedures to determine maximum lateral deflection for glass simply supported on four sides. This method does not apply to glass that 12a1 been subjected to severe surface degradation or abuse such as weld splatter or sand blasting.
The intent of Appendix X9 is to provide a method that allows the user to perform engineering analysis of lami- X9.
