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 [5] ASTM E – Glass strength evaluation prior to ASTM E Twelve U.S. glass thickness designations were covered from millimetre to millimetre.

All loads are considered normal to the glass surface. Therefore the LR of the IG is: As the area of glass under a given stress increases there is an increased risk of breakage occurring.

Polished Edges, MPa psi Minimum Thickness, mm in. 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.

The final thickness and type of glass selected also depends upon a variety of other factors see 5. Effective awtm for deflection: Appendix X1 presents additional procedures to determine the approximate maximum lateral deflection for a specified load on glass simply supported on four sides.

The lower charts of Fig. By joining you are opting in to receive e-mail. The forced constant amplitude, fixed frequency tension oscillation test specified in Table 1 and Fig.

The load sharing is then based on the individual ply thicknesses of the LG. Download Now White Paper: Interlayer samples shall experience full laminating thermal history prior to measurement. It is possible that the information presented in the NFL charts may change as further data becomes available. Please fill this form, we will try to respond as soon as possible.

Appendix X1 provides additional procedures to determine maximum lateral deflection for glass simply supported on four sides. Thank you for helping keep Eng-Tips Forums free e1300–12 inappropriate posts.

asstm Contact the interlayer manufacturer for appropriate shear modulus values. ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard. A number in parentheses indicates the year of last reapproval.

Typical load duration-temperature combinations for design purposes are: A larger combined dimension may result in excessive sealant stress and glass stresses due to temperature and altitude conditions.

This practice shall not apply to other applications including, but not limited to, balustrades, glass floor panels, aquariums, structural glass members, and glass shelves. Therefore the AN lite probability factor axtm Approximate Center of Glass Deflection Determination in SI Units—Determine the approximate center of glass deflection associated with a vertical by by 6-mm rectangular glass plate subjected to a uniform lateral load of 1.

The outboard lite Lite No.

E 1300 – 12ae1

This method does s1300-12 apply to glass that has been subjected to severe surface degradation or abuse such as weld splatter or sand blasting.

The factor for all IG units is: These factors include but are not limited to: For these loading duration and temperature considerations the interlayer shear modulus, G, is determined to be 0.

Such deflections, which will exceed the lite thickness, should be rounded to the nearest mm 0. Join your peers on the Internet’s largest technical engineering professional community.

The NFL is thus found to be 2. These minimum glass thicknesses are presented in Table 4. If the LR is greater than or equal to the specified design load, then the glass types and thicknesses are acceptable for a breakage e3100-12 of less than, or equal to, 8 in
