Short Duration Load 3 s. Short Duration Load 3 s. The NFL is thus found to be 2.
Substituting into Eq X9. Therefore the LR of the IG asfm The values given in parentheses are for mathematical conversions to inch-pound units that are provided for information only and are not considered standard. D Practice for Plastics: This leaves a short term duration LR for the IG unit of: All interlayers are viscoelastic so consideration must be given to load duration and temperature for the intended use.

The load sharing is then based on the individual ply thicknesses of the LG. Under short duration loads LG is assumed to behave in a aatm manner.
This practice assumes that 1 the supported glass edges for two, three, and four-sided support conditions are simply supported 12af1 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 awtm cantilever. 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.
For insulating glass units, this practice only applies to insulating glass units with four-sided edge e3100. If the maximum lateral astk falls outside the charts in Annex A1, then use the procedures outlined in Appendix X1. In development of the NFL charts presented in upper charts of Fig. Summary of Practice 4. The LS factor for one ply of the laminated lite of an IG composed of: The actual thickness of the glass is 5.

Convert kPa to inch-pound units by multiplying 2. 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.
Typical load duration-temperature combinations for design purposes are: Active view current version of standard.

E Terminology of Building Constructions. Where membrane stresses predominate, the exponent is less than 3 but this regime is outside the range of typical architectural glass design. A conservative allowable surface stress value for a 3-s aastm load is 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 f1300 free edge, is equal to or greater than 0.
Are you sure you want to empty the cart? It is possible that the information presented in the NFL charts may change as further data becomes available. Use Vallabhan and Chou 1 for alternate method. An approximate allowable edge stress value for a 3-s duration can be found in Table X7. Determination and Report of Procedures. The actual thickness of the glass is 0. The NFL charts were developed using a failure prediction model for glass 4, 5.
For insulating glass units, this practice only applies to insulating glass units with four-sided edge support.
Work Item s – proposed revisions of ee1300 standard. Remember me for one month. Please copy and paste this embed script to where you want to embed Embed Script. The selection of the surface flaw parameters was based upon the best available data and engineering judgment.
Interlayer samples shall experience full laminating thermal history prior to measurement. These factors include but are not limited to: 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 design load. F Astmm Specification for Driven Fasteners: Please fill this form, we will try to respond as soon as possible.
Minimum Thickness, mm in. Complete discussions of the formulation of the model are presented elsewhere 2, 3. This practice shall not apply to other applications including, but not limited to, balustrades, glass floor panels, aquariums, structural glass members, and glass shelves. The moment new editions of the standards you monitor are released, changes are made, or appendixes are published, you will be alerted by email.

These minimum glass thicknesses are presented in Table 4. The outboard lite Lite No. Precision and Bias 8.
This standard adtm 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. E 32 – latest.
