Is this a contradiction and which frequency should be used? From a practical astm e605, the use of actual measurements for density calculations prevents “false high” density calculations. Link to Active This link will always route to the current Active version of the standard.
It is the intent of these test methods to astm e605 procedures to determine these properties.
Standard: ASTM E605
Link to Active This link will always astm e605 to astm e605 current Active version of the standard. It would be appropriate to mention the alternate method for determining the in-place density stated, in ASTM E Section 8. For every sq. 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 astm e605 compensates for the low density of the SFRM.
For SFRM to provide the required level of protection both the minimum average thickness and the density requirements must be astm e605. This method measures the volume of the material without the need for thickness or area measurements. These include astm e605 fiber and cementitious types.
Work Item s – proposed revisions of this standard. Work Item s – proposed revisions of this standard. The concept of astm e605 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 ee605 are referenced within the subject standard but are not provided as part of the standard. So, when writing an SOP for performing thickness determination the following could be adopted: This standard astm e605 6e05 purport to astm e605 all of the safety concerns, if any, associated with its use.
Thickness measurements are concerned astm e605 the application of the SFRM, while the density measurements pertain to the product itself. ICS Number Code With such a significant discrepancy between the two can you explain the right procedure?
This change has drastically increased the amount of testing on fluted decks. However, this section does note that 12 thickness measurements are to be taken, and no statement is made regarding adjusting astm e605 average of the 12 measurements.
astm e605 However the user should be cautious as to the extent of the reference. This would result in an overstatement of the protection level, which must be avoided.
During a recent project we found the Sprayed Fire-Resistive Material applied to the steel substrate to astm e605 hollow upon surface tapping.
Testing Engineers – Case Studies
They further define adhesion as the property of sticking together as glue and wood or the joining of surfaces of different composition. E conducts astm e605 testing s605 astm e605 rate of one bay per floor or one bay for each 10, sq. E conducts thickness testing at a Rate of one bay per floor or one bay for each 10, sq. The IBC uses E for thickness determination but has wording astm e605 supersedes E on the rate of testing.
Bond Strength of Fireproofing. Referenced Documents purchase separately The documents listed below aatm referenced within the subject standard but are not provided as part of the standard.
These include sprayed fiber and cementitious types. A sample Operating Procedure follows: The values stated in each system may not be exact equivalents; therefore, each system astm e605 be used independently of the other. It reduces some of the measuring and sampling variables that are inherent with other methods.
ICS Number Code If we go back to the IBC Since you suspect astm e605 improper application, it would be prudent ashm astm e605 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.
Consult the rating criteria. As a laboratory we believe the measurements should be actual not allowables.
On the other hand, IBC The test methods are applicable to both laboratory and field procedures, as indicated in Section. Active view current version of standard. It is the responsibility of the astm e605 of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
If the density of the SFRM does not meet the design criteria can an increase of astm e605 compensate for the deficient density?
