5.5 Continuous surveillance and assessment of the factory production control (5.1, 1c)) The continuous surveillance and assessment of the factory production control shall cover the parameters listed in Table 4 in conjunction with EN 1279-6:2002, Annex A. NOTE There may be a need to involve a third party for the purpose of regulatory marking (see Annex ZA). The frequency of production surveillance shall be twice per year for new production facilities or for facilities that do not already have an established factory production control system in accordance with this European Standard. When assessment of FPC fails to identify major non-conformances during four successive assessments, the frequency can be reduced to once a year. When a major non-conformance is recorded, the inspection shall be repeated within two month. The frequency of production surveillance shall return to, or remain at twice a year. When the repeated inspection also results in a non-conformance, then the production shall be subject within two months to a repeated initial inspection of the factory and of the factory production control together with a surveillance inspection. When this repeated initial inspection and surveillance inspection also results in a major non-conformance then the products are considered as no longer conforming to this European Standard. SIST EN 1279-5:2005+A1:2009

The manufacturer or his agent shall organise a system of references that allows for the following:  the identification of exactly which characteristics have to be assessed (see 4.3.2);  those characteristics that will be assessed;  the values, classes, categories, etc. that have been determined for those characteristics. This system shall be documented as part of the evaluation of conformity. 6.4 “Characteristics/performance identification paper” The manufacturer shall prepare a “characteristics/performance identification paper” based on the information collected on the product characteristics (see 6.3). This document shall be part of the manufacturers technical file and is the basis for the accompanying information as required for regulator purposes. The "characteristics/performance identification paper" can be a catalogue in any media format (paper, disk, website, etc.), always identifiable by the reference that accompanies the marking with the product. The catalogue shall contain the values or classes of the characteristics for which a performance is declared. If no performance is declared, an indication of no performance determined (NPD) shall be made. NOTE 1 The conditions of use of NPD are given in Annex ZA. NOTE 2 The catalogue should not contain any information other than that relevant to the “characteristics/performance identification paper”. SIST EN 1279-5:2005+A1:2009

Use of IGUs when subjected to UV and/or in SSG A.1 General The scope of the EN 1279 series of standards does not cover the use of IGUs in these applications. However, IGUs are used in these applications and should be capable of offering the same durability and performance as an IGU used in a frame system. A.2 System description The manufacturer should be able to write a system description for this particular end use application. The description should contain, over and above that required by EN 1279-1, the following information that is specific to this intended end use: a) design considerations, e.g. resistance against wind, snow, permanent load, and other mechanical, (quasi-)static action; b) dimensioning of the seal system in accordance with !EN 13022-1"; c) specification of the ultra-violet resistant/structural sealant in accordance with !EN 15434"; d) specific factory production control requirements over and above those in EN 1279-6. A.3 Testing The durability of the insulating glass unit design should be determined by testing in accordance with EN 1279-2 and EN 1279-3. The performance of the ultra-violet resistant/structural sealant should be checked in accordance with EN 1279-4 and !EN 13022-1". A.4 Evaluation of conformity This should be in accordance with this European Standard taking account of the requirements for factory production control from EN 1279-6 and the system description. A.5 Marking Insulating glass units for this specific end use should be marked as follows: Name or trade mark of the manufacturer; EN 1279; Special end use – UV and/or structural [as appropriate]. A.6 Regulatory marking An example of a CE Marking label is shown as Figure ZA.2. SIST EN 1279-5:2005+A1:2009

Installation of the insulating glass units B.1 General In order to satisfy the relevant aspects of the performances related to health, safety and energy saving during an economically reasonable working life as it is aimed by the scope of this European Standard, it is recommended that the subclauses below relating to glazing and installation are followed. B.2 Appropriate supports Within this European Standard an appropriate support is understood as a support where: a) the sides of the insulating glass unit are covered by fixing beads or some other part of the support, and b) entrapment of stationary water, long term condensation and/or enhanced water vapour pressure against the seal of the insulating glass is prevented in order to avoid chemical and/or physical attack on the components of the insulating glass and to avoid excessive water vapour penetration into the insulating glass, and c) showing a sufficient stiffness to limit the edge deflection of the insulating glass unit under loads, such as wind and snow, to avoid reduction of service life, e.g. due to loss of adhesion. A means of obtaining a recommended minimum support stiffness is to consider when the support either over the height H or over the width B of the glazing together with an infill of low edge rigidity, e.g. a single glass, exhibits a deflection of H/200 or less, and B/200 or less, and a maximum of 12 mm for either when exposed to design loads, either as single load or as combined load. B.3 Installation and glazing conditions B.3.1 General Depending on materials and devices used for installation and glazing, and depending on the system of insulating glass unit, the installation conditions may vary.
