The apparatus, materials, wstm procedure used to apply the SFRM for laboratory tests shall be the same as is ast, for the construction of either of the test assemblies described in Test Methods E and E E6005 values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.

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.

While the wording in the manual seemed confusing, an appendix clarified that 12 thickness measurements should be taken. As a laboratory we believe the measurements should be actual not allowables. The IBC uses E for thickness determination but has wording that supersedes E on the rate of testing.

The test methods are applicable to both laboratory and field procedures, as indicated in Section 7. However the user should be cautious as to the extent of the reference. So, when writing an SOP for performing thickness determination the following could be adopted: When measuring density, IBC refers us to section 8. E conducts thickness testing at a Rate of one bay per floor or one bay for each 10, sq.


Combining values from the two systems may result in non-conformance with the standard. It reduces some of the measuring and sampling variables that are inherent with other methods.

This change has drastically increased the amount of testing on fluted decks. The concept of a correction formula has a valid basis and should not be considered as a loop hole or an easy way out.

ASTM E605/E605M – 93(2015)E1

A sample Operating Procedure follows: E conducts thickness testing at a rate e05 one bay per floor or one bay for each 10, sq. Is this a contradiction and which frequency should be used? This method measures the volume of the material without the need for thickness or area measurements.

Thickness measurements are concerned with the application of the SFRM, while the density measurements pertain to the product itself.

He stated the following: Link to Active This link will always route to the current Active version of the standard. Consult the rating criteria.

With such a 6e05 we refer to IBC Also I would encourage you and your team to use the displacement method for determining density, Section 8. They further define adhesion as the property of sticking together as glue and wood or the joining of surfaces of different composition.

When this question was asked of Luke Woods of W. Historical Version s – view previous versions of standard. Cutting around the cap down to the substrate will isolate aztm bond strength to only adhesion and may there by indicate why your project sounds hollow but would not be a standard method to substantiate an unacceptable application of SRFM.


It can be used to retest a sample that may be in question. If the density of the SFRM does not meet the design criteria can an increase of thickness compensate for the deficient density? From a practical viewpoint, the use of atsm measurements for density calculations prevents “false high” density calculations. With such a significant discrepancy between the two can you explain the right procedure?

If we go back to the IBC My question is after setting the cap with epoxy and letting it set for approximately 24 hours are we to cut around the cap to the substrate or are we to test it in-place without cutting around the cap?

Testing Engineers – Case Studies

It would be appropriate to mention the alternate method for determining the in-place density stated, in ASTM E Section 8. For every sq. Since you suspect an improper application, it would be prudent to test the SFRM in the standard method and to also cut around the cap and test just for adhesiveness and report the findings to the design professional.
