Full title and description

AS 4046.5-2002 (Amdt 1-2006) — Methods of testing roof tiles — Determination of permeability. Specifies a standardized laboratory procedure for measuring the permeability (water penetration) of roof tiles under defined test conditions; includes the 2006 amendment incorporated into the 2002 edition.

Abstract

This standard defines the test method used to determine the permeability of roof tiles. It describes required apparatus, specimen preparation and conditioning, the test procedure for applying water under specified conditions, measurement and calculation of water penetration, and reporting requirements. The document was issued as the second edition in 2002 and reissued to incorporate Amendment 1 in 2006 (reconfirmation recorded in 2015).

Scope

Sets out a laboratory method for determining the permeability of roof tiles — that is, the tendency for water to pass through or around a tile under specified testing conditions. The procedure is intended for use with roof tiles in both quality control and type-testing contexts and complements other tests in the AS 4046 series dealing with tile distortion, freeze–thaw resistance and other performance characteristics.

Key topics and requirements

• Definitions and terminology relevant to permeability testing of roof tiles.
• Required test apparatus and fixtures (water supply, heads, mounting rigs and detectors for penetration).
• Specimen selection, conditioning and mounting procedures to ensure repeatability.
• Step-by-step test procedure: application of water, exposure times, and measurement of penetration.
• Calculation and expression of test results (reporting of numeric permeability/penetration outcome and any observation of leakage paths).
• Reporting format and information to be recorded (test conditions, specimen identification, results, deviations).
• Notes on interpretation and relationship to other AS 4046 series tests.

Typical use and users

Used by tile manufacturers for quality control and product development, independent test laboratories conducting type and compliance testing, building product certifiers, architects and specifiers assessing product suitability for applications, and regulators or consultants evaluating roof covering performance under water exposure conditions.

Related standards

Part of the AS 4046 series of roof-tile test methods (for example AS 4046.1, AS 4046.6 etc.). It is commonly used alongside AS 2049 (Roof tiles) and other product- and performance-related Australian Standards that address tile dimensions, distortion, freeze/thaw resistance and installation practice.
