Combining values from the two systems may result in non-conformance asm the standard. If we go back to the IBC When measuring density, IBC refers us to section 8.
It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory atsm prior to use. Also I would encourage you and your team to use the displacement method for determining density, Section 8. Is this a contradiction and which frequency should be used?
Historical Version s – view previous versions of standard. Thickness measurements are asfm with the application of the SFRM, while the density measurements pertain to the product itself. So, when writing an SOP for performing thickness determination the following could be adopted: However, this section does note that 12 thickness measurements are to be taken, and no statement is made regarding adjusting the average of the 12 measurements. As a laboratory we believe the measurements should be actual not allowables.
Testing Engineers – Case Studies
The apparatus, materials, and procedure used to apply the SFRM e05 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 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? Bond Strength of Fireproofing.
It is based on the same design concept of the original 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.
Work Item s – proposed revisions of this standard. It makes no reference to Note 4 in using a correction formula. When this question was asked of Luke E05 of W.
However the user should be e6605 as to the extent of the reference. While the wording in the manual seemed confusing, an appendix clarified that 12 thickness measurements should be taken. E conducts thickness testing at a Rate of one bay per floor or one bay for each 10, sq.
Consult the rating criteria. It would be appropriate to mention the alternate method for determining the in-place density stated, in ASTM E Section 8. The concept of a correction formula has a valid basis and should not be considered as a loop hole or an easy way out.
A sample Operating Procedure follows: If the density of the SFRM does not meet the design criteria can an increase of thickness compensate for the deficient density?
ASTM E605/E605M – 93(2015)E1
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.
The test methods are applicable to both laboratory and field procedures, as indicated in Section 7. You are correct, asfm averaging calculations for thickness measurements as mentioned in ASTM E section 8.
Link to Active This link will always route to the current Active version of the standard. From a practical viewpoint, the use of actual measurements for density calculations prevents “false high” density calculations.
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 e650 with other methods.
During a recent project we found the Sprayed Fire-Resistive Material applied to the steel substrate to sound hollow upon surface tapping. 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. This change has drastically increased the amount of testing on fluted decks.
It is the intent of these test methods to provide procedures to determine these properties. This would result in an overstatement of the protection level, which must be avoided. This method measures the volume of the material without the need for thickness or area measurements.
The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
