F Standard Specification for Driven Fasteners: Nails, Spikes, and Staples.

The NFL is thus found to be 2. These minimum glass thicknesses are presented in Table 4. The benefits of a subscription: Precision and Bias 8. If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below. The load sharing is then based astn the individual ply thicknesses of the LG.

For glass simply supported on three sides, the ratio of the length of one of the supported asstm perpendicular to the free edge, to the length of the free edge, is equal to or greater than 0. Will this window glass support a 1. The maximum allowable stress allowable is a function of area Aload duration 12se1 seconds dand probability of breakage Pb.

Therefore the LR of the IG is: The information in this practice applies only to polyvinyl butyral PVB interlayer or those interlayers that demonstrate equivalency according to Appendix X8.


E 1300 – 12ae1

As the area of glass under a given stress increases there is an increased risk of breakage occurring. The intent of Appendix X9 is to provide a method that allows the user to perform engineering analysis of lami- X9.

This service is not available if you are a URL user where you ashm not log in with an email address. These factors include but are not limited to: A larger combined dimension may result in excessive sealant stress and glass stresses due to temperature and altitude conditions.

Land Use and Development. E Terminology of Building Constructions. This ensures that you are always up-to-date and saves you both time and money.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. The construction of two 2. The moment new editions of the standards you monitor are released, changes are made, asmt appendixes are published, you will be alerted by email. Approximate Center of Glass Deflection Xstm 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.

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. Effective thickness for stress: For insulating glass units, this practice only applies to insulating glass units with four-sided edge support.


The final thickness and type of glass selected also depends upon a variety of other factors see 5. Use Vallabhan and Chou 1 for alternate method. This is due to sealed air space pressure differences caused by changes in: Read more about subscriptions. Significance and Use 5.

The specified design load shall be used for this calculation. Effective thickness for deflection: Contact the interlayer manufacturer for appropriate shear modulus values.

Interlayer samples shall experience full laminating thermal history prior to measurement. Note that Section 6 references a Pb less than or equal 1a2e1 0. All interlayers are viscoelastic so consideration must be given to load duration and temperature for the intended use.

We need your help! The actual thickness of the glass is 5. Current edition approved May 1, Polished Edges, MPa psi The final thickness and type of glass selected also depends upon a variety of other factors see 5.

Are you sure you want to empty the cart? The factor for all IG units is: If the LR is greater than or equal to the specified design load, then the glass types and thicknesses are acceptable for a breakage probability of less 12we1, or equal to, 8 in
