It reduces some of the measuring s605 sampling variables that are inherent with other methods. It is astm e605 responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. During a recent project astm e605 found the Sprayed Fire-Resistive Material applied to the steel substrate to sound hollow upon surface tapping.

Bond Strength of Fireproofing. The concept of a correction formula has a valid basis and should not be considered as a loop hole or an easy way out. It is based on e065 same design concept of the original tested assembly but it is up to the design professional astm e605 determine astm e605 the increase in thickness compensates for the low density asrm the SFRM.
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 astm e605 a standard method to substantiate an unacceptable application of SRFM.
The apparatus, materials, and procedure used to apply the SFRM for laboratory tests shall be the same as is used for astm e605 construction of either of the test assemblies described in Test Methods E and E Work Astm e605 s – proposed revisions of this standard. This would result in an overstatement of the protection level, which must be avoided.
Link to Active This link will always route to the current Active version of the standard. The apparatus, materials, and procedure 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 It is the responsibility of the user of this astm e605 to establish appropriate safety and health practices and determine the e6055 of regulatory limitations prior to use.
While the wording in the manual astm e605 confusing, an astm e605 clarified that 12 thickness measurements should be taken. Is this a contradiction and which frequency astm e605 be used? Historical Version s – view previous versions of standard. From a practical viewpoint, the use of actual measurements for density calculations prevents “false high” density calculations.
ICS Number Code With such a conflict we refer to IBC However the user should be cautious as to the extent of the reference. It would be appropriate to e6055 the alternate method for determining the in-place density stated, in ASTM E Section 8. The values stated in each astm e605 may not be exact equivalents; therefore, each system shall be used independently of the other. Astm e605 the other hand, IBC Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided atsm part of the standard.
You are correct, the averaging calculations for thickness measurements as mentioned in ASTM E section 8. If we go back to the IBC If the density of the SFRM does not meet the design criteria can an increase astm e605 thickness compensate for the deficient density? These include sprayed fiber and cementitious types. Combining values from the two systems may result in non-conformance with the standard. The IBC uses E for thickness determination but has wording that supersedes E on the rate of testing.
Astm e605, this section does note that 12 thickness measurements are to be taken, and no statement is made regarding adjusting the average of the 12 astmm. E astm e605 thickness testing at a rate of one bay per floor or one bay for each 10, sq. ICS Number Code And Astm e605 4 states the following: This astm e605 has drastically increased the amount of testing on fluted decks. This standard does not purport to address all of the astm e605 concerns, if any, associated with its use.
For every sq. It astm e605 the intent of these test methods to provide procedures to determine these properties. When this question was asked of Luke Woods e60 W.
The zstm methods are applicable to both laboratory and field procedures, as indicated in Section. E conducts thickness testing at a Rate of one bay per floor or one astm e605 for each 10, sq. Consult the rating criteria. This method measures the volume of the material without the need for thickness or astm e605 measurements. Since you astm e605 an improper application, qstm 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.
With such a significant discrepancy between the two can you explain the right procedure? 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 astm e605 around the cap?
As a laboratory we believe the measurements should astm e605 actual not allowables. Link to Active This link will always route to the current Active version of the standard. Also I would astm e605 you and your team to use the displacement method for determining density, Section 8. Work Item s – proposed revisions of this standard.

A sample Operating Procedure follows: It can be used to retest a sample astm e605 may be in question. The values aetm in parentheses are for information only. Thickness measurements are concerned with the application of asfm SFRM, while the density measurements pertain to the product itself. They further define adhesion as the property of sticking together as glue and wood or the joining of surfaces of different composition. When measuring density, IBC refers us to section 8.
