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.
E 1300 – 12ae1
Atsm 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by the responsible technical committee and must be reviewed every five years and if not revised, either reapproved or withdrawn.
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. Long Duration Load 30 days.
The NFL charts were developed using a failure prediction model for glass 4, 5. A conservative allowable surface stress value for a 3-s duration load is Read more about astk.
Therefore the AN lite probability factor becomes: Such deflections, which will exceed the lite thickness, should be rounded to the nearest mm 0.
Home E – 12ae1 E – 12ae1 September 14, Author: Size px x x x x For insulating glass units, this practice only applies to insulating glass units with four-sided edge support. The actual thickness of the glass is 0. No recommendations are made in this practice regarding acceptable lateral deflections. 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.
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 12qe1 supported beam; and 3 glass supported on one side acts as a cantilever. Determine if the skylight will support a 6. Minimum Thickness, mm in. NOTE 2—Values are approximated.
Print 1 2 3 4 5 page sstarting from page current page. The factor for all IG units is: These effective thickness values can be used with standard engineering formulae or finite element methods for calculating both deflection and glass stress of laminates subjected to load. Report “E – 12ae1”. Interlayers comprised of differing polymers in multiple layers are not covered in this procedure.
C Standard Specification for Flat Glass.
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. Determination and Report of Procedures. NOTE 4—The user is recommended to limit the combined width of both air spaces in the IG unit to less than or equal to 25 mm 1 in.
Significance and Use 5. The information in this practice applies only to polyvinyl butyral PVB interlayer or those interlayers that demonstrate equivalency according to Appendix X8. E Terminology of Building Constructions. The shear modulus value shall be determined following Practice D There were no books found for the applied search filters.
This practice shall not apply to other applications including, but not limited to, balustrades, glass floor panels, aquariums, structural glass members, and glass shelves. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard. These flaw parameters represent the surface strength of weathered window glass that has undergone in-service conditions for approximately 20 years. This method does not apply to glass that has been subjected to severe surface degradation or abuse such as weld splatter or sand blasting.
