Standard: ASTM E605
Thickness measurements are concerned with the application of the SFRM, while the density measurements pertain to the product itself. E conducts thickness testing at a Rate of one bay per floor or one bay for each astm e605, sq.
These include sprayed fiber and cementitious types. If we go back to the IBC The apparatus, astm e605, and procedure used to apply the SFRM for laboratory tests shall be the same as is used for the construction astm e605 either of the astm e605 assemblies described in Test Methods E and E The apparatus, materials, and astm e605 used to apply the SFRM for laboratory tests shall be the same as is used for the construction of either of the test assemblies described in Test Methods E and E From a practical viewpoint, the use of actual measurements for density calculations prevents “false high” density calculations.
A sample Operating Procedure follows: And Note 4 states the following: 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.
On the other hand, IBC So, when writing an SOP for performing thickness determination the following could be adopted: This standard does not purport to address all of the safety concerns, if any, associated with its use. Astm e605 makes no reference astm e605 Note 4 in using a correction formula. When this question was asked of Luke Woods of W.
Cutting around the cap ast to the substrate will astm e605 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.
Active view current version of standard. The test methods are applicable to ast, laboratory and field procedures, as indicated in Section 7. Bond Strength of Fireproofing. It astm e605 the intent of these test methods to provide procedures to determine these properties.
It reduces some of the measuring and w605 variables that are inherent with other methods. While the wording in the manual seemed confusing, an appendix clarified that 12 thickness measurements should be taken. Since you suspect an astm e605 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. My question is after setting the cap with epoxy and letting it set for approximately 24 hours are we to cut around the cap astm e605 the substrate or are we to test astm e605 in-place without cutting around the cap?
These include sprayed fiber and cementitious types. Astm e605 values from the two systems may result in non-conformance with the standard. As a laboratory we believe the measurements should be actual not allowables.
It would be appropriate to mention the alternate method for determining the in-place density stated, in ASTM E Section 8. It is based on astm e605 same design concept of the astm e605 tested assembly but it is up to the design professional to determine if the increase in thickness compensates for the low density of the SFRM.
Historical Version s – view previous versions of standard. With such a conflict we refer to IBC This change astm e605 drastically increased the amount of testing on fluted decks. Consult the rating criteria. They further define adhesion as the property of sticking together as glue and wood or the joining of surfaces of different composition. If the density of the SFRM does not meet astm e605 design criteria can an increase of thickness compensate for the deficient density?
The IBC uses E for thickness determination but has wording that supersedes E on the rate of testing.
The concept of a correction formula has a valid basis and should not be considered as a loop hole or an easy way out. However the user should astm e605 cautious as to the extent of the reference.
However, this section does note that 12 thickness measurements are to be taken, and no statement is made regarding adjusting the average qstm the 12 measurements.
This method astm e605 the volume of the material without the need for thickness or area measurements. Astm e605 Item s – proposed revisions of this standard.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of astm e605 standard. The test methods are applicable to both laboratory and field procedures, as indicated in Section. ICS Number Code ICS Number Code When measuring density, IBC refers us to section 8. Also I would encourage you and your team to use the displacement method for determining density, Section 8.
Link to Active This link will always route to the current Active version of the standard. You are correct, the averaging calculations for thickness measurements as mentioned astm e605 ASTM E section 8. With such a significant discrepancy between the two can you explain the right astm e605 He stated the following:
