1.Inspection conditions Guidelines for Glass Quality

1.1 For general applications quality inspection is routinely carried out by visual observation that is looking through the glass in normal incidence (i.e. at 90 degrees to the glass surface). In line with the Glass and Glazing Federation (GGF) and CWCT Guidelines, the glass shall be viewed from a distance of not less than 3 metres away. The use of strong lamps and/or magnifying devices is not allowed. It is not permissible to find defects at close range and then mark them so as to be visible from the given viewing distance.

1.2 Internal Glazing/Internal Partitions<br>Inspection of internal glazing applications should be carried out under normal diffuse background lighting conditions, with illumination as usual and appropriate for the specific room (e.g. no spot lights), viewed at a right angle to the glass surface

1.3 External Glazing/Façade Applications<br>Inspection of external glazing applications should be carried out under normal diffuse daylight conditions, (e.g. cloudy sky) not in direct sunlight or with aid of artificial light and with no visible moisture on the glass. Inspection shall be from the room side and relates only to transmission and not reflection

2.0 Admissible Flaws<br>When viewed in accordance with section 1, the glass shall be subject to the acceptance criteria described in 1.1 and 1.2.<br>2.1 Point Body Defects<br>(e.g. bubbles, seeds, spot faults and linear/ extended faults) the glass meets the requirements of the relevant parts of BS EN 572 for finished cut sizes of basic soda lime silicate glass when viewed from a distance of not less than 3 metres away.<br>2.2 Chip, Nicks, Edge Defects<br>Glass defects such as edge chips are permissible up to 2mm or 20% of the glass thickness, while chips can be up to 8mm. Cracks, even minor – are not permissible and should be reported at glass receipt.<br>2.2 Surface Defects<br>Any scar or visible faults on the surface glass visible from 3 metres are not allowed. A single individual fine scratch up to 25 mm long is permissible and the sum of individual fine scratches up to a maximum of 45 mm. Glass is often scratched during service and deep scratches can reduce the strength and integrity of the product. If a scratch in the surface of the glass is deep enough to be felt with a “finger nail” then we would recommend that the glass is repaired or replaced.

4.0 Viewing criteria for finishes<br>The inspection criteria for the products given in the following standards are suitable for use on site for final visual acceptance, primarily to check for on-site damage. It must however be appreciated that potential defects such as peeling of organic coatings or chalking, leaching, saps pockets, efflorescence etc. cannot be identified prior to exposure by visual assessment and comprehensive quality control inspection at the manufactures.<br>BS6496 Specification for powder organic coatings for application and stoving to aluminium alloy extrusions, sheet and preformed sections for external architectural purposes, and for the finish on aluminium alloy extrusions, sheet and preformed sections coated with powder organic coatings. The standard requires, “That the finish on significant surfaces shall show no scratches through to the substrate. When the finish on significant surface is evenly illuminated in defused daylight as described in BS3900-D1 and is examined at a 90 degree angle with normal or corrected vision, no blisters, craters, pinholes or scratches shall be visible from a distance of not less than 5 m for external architectural applications or 3 m for internal architectural applications.”<br>BS 3987 Specification for anodic oxidation coatings on wrought aluminium for external architectural applications. This standard requires that anodised articles shall be free from visible defects on the significant surfaces when viewed from a distance of not less than 5 m for external architectural applications or 3 m for internal architectural applications. The agreed samples used to produce colour and texture limits should, where possible, be duplicates of production components, but should in any case be shaped so as to facilitate comparison with the production component.<br>

Hand Over -Cladding free from damage-Facades to be viewed as per the BBA, in daylight from a distance of not less than 10m. Some variation in colour and texture of external walls is inevitable and in certain cases is a feature. A façade, for instance, should be inspected for scratches or minor imperfections from a distance of min 5m, if a scratch cannot be seen from that distance then it is not a defect except if a scratch has gone through the full depth of the coating exposing the raw metal below.
