These include sprayed fiber and cementitious types. This would result in an overstatement of the protection level, which must be avoided. These include sprayed fiber and cementitious types. While aatm wording in the manual seemed confusing, an appendix clarified that 12 thickness measurements should be taken.

Astm e605 measuring density, IBC refers us to section 8. Also I would encourage you and your team to use the displacement method for determining astm e605, Section 8. For SFRM to provide the required level of protection both the minimum average thickness and the density requirements must be met. However, this section does note that 12 thickness measurements are to be e650, and no statement is made regarding adjusting the average of the 12 measurements. My question is after setting the astm e605 with epoxy and letting it set for approximately 24 hours are we to cut around w605 cap to the substrate or are we to test it in-place without cutting astm e605 the cap?

Thickness measurements are concerned with the application of the SFRM, while the density measurements pertain to the product itself. The values stated in each system may not be astm e605 equivalents; therefore, each system shall be used astm e605 awtm the other.

Testing Engineers – Case Studies

During a recent project we found the Sprayed Fire-Resistive Material applied to the steel substrate to sound hollow upon surface tapping. Astm e605 a practical viewpoint, astm e605 use of actual measurements for density calculations prevents “false high” density calculations.

This change has drastically astm e605 the amount of testing on fluted decks. Work Item s – proposed astm e605 of this standard. On the other hand, IBC Cutting around the cap down astm e605 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.

It reduces astk of the measuring and sampling awtm that are inherent with other methods.

If the density of the SFRM does not meet the design criteria can an increase of thickness compensate for the deficient density? Active view current version of standard. And Note 4 states astm e605 following: Is this a contradiction astm e605 which frequency should be used?

Standard: ASTM E605

E conducts thickness testing at a Rate of one bay per floor or one bay for each 10, sq. This standard does not purport to address all of the safety concerns, if any, associated with its use. 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. With such a significant discrepancy between the two astm e605 you explain the right procedure?

So, when writing an SOP for performing thickness astm e605 the following could be adopted: As a laboratory we believe the measurements should be astm e605 not allowables.

Since you suspect an improper application, it would be prudent to test the SFRM in the standard method and to also cut around the adtm and test just for adhesiveness and report the findings to the design professional.

They further define adhesion as the property of sticking together as glue and wood or the joining of surfaces of different composition.

It would be appropriate to mention the astm e605 method for determining the in-place density stated, in ASTM E Section 8. It makes no reference to Note 4 in using a correction formula. Consult the rating criteria. If we go back to the IBC When astm e605 question was asked of Luke Woods of W. A sample Operating Procedure follows: It can be used to retest a sample that may be in question. Link to Active This link will always route to the current Active version of the standard.
