10、ights reservedForeword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject
11、 for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC)
12、on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees
13、 are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be hel
14、d responsible for identifying any or all such patent rights. ISO 28278-2 was prepared by Technical Committee ISO/TC 160, Glass in building, Subcommittee SC 2, Use considerations. ISO 28278 consists of the following parts, under the general title Glass in building Glass products for structural sealan
15、t glazing: Part 1: Supported and unsupported monolithic and multiple glazing Part 2: Assembly rules ISO 28278-2:2010(E) ISO 2010 All rights reserved vIntroduction Structural sealant glazing, hereinafter referred to as SSG, is an assembly in which the glass products are fixed to the structural seal f
16、rame by means of a sealant. The sealant must primarily be capable of withstanding the load actions applied to the glass products and transferred to the structural seal frame but can also function as a barrier against the passage of air and water through a building envelope. Structural sealant glazin
17、g can be considered a product. It can also be considered an assembly method for glass into or onto a framework. In the first consideration, the conditions are to be fulfilled by a manufacturer in order to place a complete structural sealant glazing and structural sealant glazing kit on the market, i
18、ntended to be sold as one complete product in one (trade) transaction In the second consideration, the framework, glass products, sealant and accessories, materials and components can be the subject of separate, independent (trade) transactions, independently ordered, and supplied on the constructio
19、n site or in a workshop where an assembler only assembles the various materials and component elements and subsequently installs the construction, all in accordance with the conditions and under the responsibility of a designer. Only when the design of a building can be such that the glass products
20、should be installed directly in the building using a structural glazing technique, but under controlled environmental conditions as expressed in Clause 5 of this document, should this part of ISO 28278 apply. This means that the assembler is only responsible for the assembly, not for the design. Ass
21、embly and design are two separate tasks with their own responsibilities. However, in a number of countries, contractors have the duty to warn architects if there is a view that something in the design is wrong. An analogy would be the case where it is assumed that the assembler has the same duty tow
22、ards the designer. In order to give the assembler a feeling of what the design considerations are, and at the same time to understand what information he or she requires from the designer, design guidance is given in this part of ISO 28278 in Annex C.

23、010 All rights reserved 1Glass in building Glass products for structural sealant glazing Part 2: Assembly rules 1 Scope This part of ISO 28278 gives guidelines for the assembly and bonding of glass elements in a frame, window, door or curtain-walling construction, or directly into the building by me
24、ans of structural bonding of the glass element into or onto the framework or directly into the building. It gives the assembler information that enable him to organize his work and comply with requirements regarding quality control. Quality control of the assembly process is of the highest importanc
25、e. This part of ISO 28278 provides the minimum requirements for acceptable quality control of the process of structural sealant glazing (SSG) on a single project. The annexes contained at the end of this part of ISO 28278 provide the methods to ensure proper application and documentation for a safe
26、and weatherproof glazing assembly product. This process is intended to be applicable to most SSG projects. The project testing on metal substrates and glass products will determine proper surface preparation and installation instructions. These rules do not apply to the adhesion or durability of the
27、 paint finishes or glass products. This is not intended to be a durability test requirement for the paint and glass products commonly used in the SSG process. The structural, weatherproofing and sealant products which are commonly used in structural glazing applications are those based on organosilo
28、xane, “silicone” polymers. This part of ISO 28278 does not preclude the use of other sealant types, where these can demonstrate suitability for service according to this part of ISO 28278 and when they are used following the recommendations of the sealant manufacturer. Supports to be taken into cons
29、ideration shall be only metallic substrates, uncoated glass, coated glass and ceramic frit enamelled glass. This part of ISO 28278 relates to SSG systems for use in faades and roofs, or parts of them, with glazing with slopes as shown in Figure 1. Faades with an inclination of less than 15 from the
30、vertical are considered vertical faades. If the slope to the outer side has an inclination above 50, the glass is considered unsupported glass.
