Is this a contradiction and which frequency should be used? So, when writing an SOP for performing thickness determination the following could be adopted: However, this section does note that 12 astn measurements are to be taken, and no statement is made regarding adjusting the average of the 12 measurements.

With such a significant discrepancy between the two can you explain the right procedure? Thickness measurements are concerned with the application of the SFRM, while the density measurements pertain to the product itself. As a laboratory we believe the measurements should be actual not allowables.

Bond Strength of Fireproofing.

Cutting around the cap down to the substrate will isolate the 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. Consult the rating criteria. 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.

The IBC uses E for thickness determination but has wording that supersedes E on the rate of testing. It reduces some of the measuring and sampling variables that are inherent with other methods. And Note 4 states the following: The test methods are applicable to both laboratory and field procedures, as indicated in Section 7.

The concept of a correction formula has a valid basis and should not be considered as a loop hole or an easy way out. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Combining values from the two systems may result in non-conformance with the standard.

Ee605 makes no reference to Note 4 in using a correction formula. He stated the following: E conducts thickness testing at a rate of one bay per floor or one bay for each 10, sq. You are correct, the averaging calculations for thickness measurements as mentioned in ASTM E section 8. When this question was asked of Luke Woods of W. If we go back to the IBC The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.

A sample Operating Procedure follows: While the wording in the manual seemed confusing, atsm appendix clarified that 12 thickness measurements should be taken. During a recent project we found the Sprayed Fire-Resistive Material applied to the steel substrate to sound hollow upon surface tapping. With such a conflict we refer to IBC This would result in an overstatement of the protection level, e05 must be avoided.

Also I would encourage you and your team to use the displacement method for determining density, Section 8. If the density of the SFRM does not meet the design criteria can an increase of thickness compensate for the deficient density?

Link to Active This link will always route to the current Active version of the standard. These include sprayed fiber and cementitious types.

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?

From a practical viewpoint, the use of actual measurements for density calculations prevents “false high” density calculations. It is the intent of these test methods to provide procedures to determine these properties. E conducts thickness testing at a Rate of one bay per floor or one bay for each 10, sq. On the other hand, IBC For SFRM to provide the required level of protection both the minimum average thickness and the density requirements must be met.

It can be used to retest a sample that may be in question. The apparatus, materials, and procedure used to apply the SFRM for laboratory tests shall be the same as is aetm for the construction of either of the test assemblies described in Test Methods E and E For every sq.

ICS Number Code Work Item s – proposed revisions of this standard. 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 s605 adhesiveness and report the findings to the design professional.

When measuring density, IBC refers us to section 8. Historical Version s – view previous versions of standard.
