1 INTRODUCTION
This report contains the minimum information sufficient for regulatory compliance and refers to the Assessment report EWFA 32796900.
The referenced report presents an assessment of the fire resistance performance of Hilti Firestop Intumescent Sealant CP 611A protecting single cable penetrations in apertures less or equal to Ø40mm in wall constructions if tested in accordance with AS1530.4-2005 and assessed in accordance with AS4072.1-2005.
The tested prototypes described in Section 2 of this report, when subject to the proposed variations described in Section 3 and tested in accordance with the referenced test method described in Section 4. The conclusions of the referenced report are summarised in Section 5.
The validity of the referenced assessment is conditional on compliance with Sections 7, 8 and 9 of this report.
2 TESTED PROTOTYPES
The referenced assessment references to test No. 14244A describing test of cable penetrations protected with various Hilti products penetrating plasterboard lined wall and concrete wall constructions and tested in accordance with EN 1366-3: 2009. The test was sponsored by Hilti and was conducted by EFECTIS France.
3 VARIATION TO TESTED PROTOTYPES
The proposed construction is for single cable penetration protected with Hilti Firestop Intumescent Sealant CP 611A in walls as tested in No. 14244A subject to the following variations:
• The single PVC insulated copper conducted cable sizes and corresponding minimum and maximum allowable aperture sizes are summarised in Table 1.
• The minimum distance between the cable and seal edge may be zero.
• Aperture size up to Ø40mm or any opening/shape of equivalent area, backfilling material may be omitted, and the annular gap between wall substrate and single cable penetration shall be sealed with Hilti Intumescent sealant CP 611A with a depth of at least 25mm deep on each side..
• The backfilling material is omitted.
• The wall material can optionally be masonry, concrete, AAC, Speedpanel, Speedwall panel or plasterboard lined wall.
• The plasterboard lined wall shall be constructed from minimum two layers of 13mm or 16mm thick fire grade plasterboard each side with a minimum wall thickness of 100mm that has been tested or otherwise assessed to achieve an FRL of -/120/120 or 120/120/120.
• The assessed construction is summarised in sections 3.1, 3.2 and 3.3.

6 DIRECT FIELD OF APPLICATION
The referenced assessment applies to penetrations in walls exposed to fire from either side.
7 REQUIREMENTS
The referenced report details the methods of construction, test conditions and assessed results that would have been expected had the specific elements of construction described herein been tested in accordance with AS1530.4.
Any further variations with respect to size, constructional details, loads, stresses, edge or end conditions, other than those identified in this report, may invalidate the conclusions drawn in the referenced report.
It is required that the supporting construction be otherwise tested or assessed to achieve the required FRL of the penetration seal in accordance with AS1530.4-2005.
8 VALIDITY
The referenced assessment report does not provide an endorsement by Exova Warringtonfire Aus Pty Ltd of the actual products supplied.
The conclusions of the referenced assessment may be used to directly assess the fire resistance performance under such conditions, but it should be recognised that a single test method will not provide a full assessment of the fire hazard under all fire conditions.
Because of the nature of fire resistance testing, and the consequent difficulty in quantifying the uncertainty of measurement, it is not possible to provide a stated degree of accuracy. The inherent variability in test procedures, materials and methods of construction, and installation may lead to variations in performance between elements of similar construction.
The referenced assessment can therefore only relate only to the actual prototype test specimens, testing conditions and methodology described in the supporting data, and does not imply any performance abilities of constructions of subsequent manufacture.
The referenced assessment is based on information and experience available at the time of preparation. The published procedures for the conduct of tests and the assessment of test results are the subject of constant review and improvement and it is recommended that the referenced report be reviewed on or, before, the stated expiry date.

The information contained in this report shall not be used for the assessment of variations other than those stated in the conclusions above. The assessment is valid provided no modifications are made to the systems detailed in the referenced report. All details of construction should be consistent with the requirements stated in the relevant test reports and all referenced documents.
