In most of our glass balustrade, frameless glass pool fencing and semi frameless glass pool fencing, we use Toughened Safety Glass.
1.4.13 Toughened safety glass—a glass which has been converted to a safety glass by subjection to a process of prestressing so that, if fractured, the entire piece disintegrates into small, relatively harmless particles. The residual surface compression is a minimum of 69 MPa.
Where glazing material is so situated that accidental breakage is reasonably foreseeable, the glazing materials and thicknesses required for wind loading may not be adequate. While the accident rate through breakage of glazing material glazed at low level is significant among most age groups, it is particularly high in the age groups up to 19 years. Research in the United Kingdom, New Zealand and Australia has shown that a high proportion of all reported accidents with glazing material involve glazed doors and side panels in all types of buildings. In certain specialized rooms, such as gymnasiums, breakage of glazing material located at high level is also a potential danger. In these and other similar danger areas, safety glazing materials meeting the requirements of this specification will reduce the risk of injury. Although these safety glazing materials will break under sufficient impact their fracture characteristics are such that if broken the likelihood of cutting and piercing injuries will be minimized.
The test requirements for the different glazing materials are designed to promote safety and to reduce or minimize the likelihood of cutting and piercing injuries from human impact.
APPLICATION This Standard applies to all safety glazing materials for use as required by AS 1288 (Selection and Installation).
1.7 MARKING Glazing material complying with this Standard shall be legibly marked with the following:
(a) The name or registered trademark of the manufacturer or supplier.
(b) The number of this Australian/New Zealand Standard, i.e. AS/NZS 2208.
(c) A letter or other code to indicate plant of manufacture or supply.
(d) Grade A or Grade B to indicate the grade of the material.
(e) A number to indicate the nominal thickness for standard glazing material (see Table 2.1) in millimetres, or a number to indicate the minimum thickness for non-standard glazing material to the nearest tenth of a millimetre.
(f) A letter or word or combinations thereof to indicate type of glazing material used in the product, as follows:
(i) The letter ‘T’ or word ‘toughened’, indicating a toughened safety glass.
If the glass supplied to you does not have all the markings nominated above, it is not fit for use in glass balustrade, frameless glass pool fencing or semi frameless glass pool fencing in Australia.
