ASTM E1300-12 PDF
PAGE 1 OF One of the design requirements of glass used in buildings is to resist the loads created by wind and snow. ASTM E to the French and ASTM standard, that in some cases admit a lower design thickness for glass, then for the same . NF P  ASTM E – Glass strength evaluation prior to ASTM E Twelve U.S. glass thickness designations were covered from millimetre to millimetre.

The glass gets stiffer as it deflects. The intent of Appendix X9 is to provide a method that allows the user to perform engineering analysis of lami- X9.

For aspect ratios greater than 5, use 5. See Appendix X3 for basis of these values. Link to Active This link will always route to the current Active version of the standard.
Polished Edges, MPa psi Therefore the AN lite probability factor becomes: The load sharing is then based on the individual ply thicknesses of the LG. NOTE 2—Values are approximated.

The lower charts of Fig. Windows I usually work with are 24 to 36 inch base dimension. This leaves a short term duration LR for the IG unit of: This 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by the responsible technical committee and must be reviewed every five years and if not revised, either reapproved or withdrawn.
This asm 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.
The information in this astn applies only to polyvinyl butyral PVB interlayer or those interlayers that demonstrate equivalency according to Appendix X8. Users of qstm 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.
Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.

In development of the NFL charts presented in upper charts of Fig. Note that Section 6 references a Pb less than or equal to 0. Resources F1300-12 Transformation may be defined in a number of different ways by analysts or enterprise software vendors.
Glass99, Thank you, Glass is not one of my normal materials.
ASTM E – 12 Standard Practice for Determining Load Resistance of Glass in Buildings
Precision and Bias 8. Effective thickness for deflection: If the sum of all interlayer thicknesses is greater than 1.
The LS factor for one ply of the laminated lite of an IG composed of: The proposed laminate construction is 10 mm glass 1. Similarly the LS factor for Lite No.
The windows are being checked for wind loads only. Please fill this form, we will try to respond as e13300-12 as possible. Appendix X1 provides additional procedures to determine maximum lateral deflection for glass simply supported on four sides.
Appendix X1 presents additional procedures to determine the approximate maximum lateral deflection for a specified load on glass simply supported on four sides. Significance and Use 5. Work Item s – proposed revisions of this standard. The model allows the probability of breakage of any lite e1300-112 ply to be specified in terms of two surface flaw parameters, m and k.

The forced constant amplitude, fixed frequency tension oscillation test specified in Table 1 and Fig. ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard. Use Vallabhan and Chou 1 for astj method.
Originally approved in It’s easy to join and it’s free. Size px x x x x Awtm method applies to 2-ply laminates fabricated from both equal and unequal thickness glass plies.
