This legislation vupòe define tolerances, flatness, machining of the edges, and the characteristics which must be paid in case of fragmentation.

This legislation has the other riferimentile following standards:

EN 572-1 Glass in building - Basic soda lime silicate glass products:

Definitions and general physical and mechanical properties

EN 572-2 Glass in building - Basic soda lime silicate glass products: Float

glass

EN 572-4 Glass in building - Basic soda lime silicate glass products: Drawn

sheet glass

EN 572-5 Glass in building - Basic soda lime silicate glass products:

Patterned glass

EN 673 Glass in building - Determination of thermal transmittance

(U value) - Calculation method

EN 1096-1 Glass in building - Coated glass - Definitions and classification

RES 12600 Glass in building - Pendulum test - Impact test method for flat glass

and performance requirements.

The safety glass silicate sodo- calcium tempered is realized through a sheet of monolithic glass and must match in case of rottoura to fragments with no sharp edges and rounded.

In the process of thermal curing can come to create deformation of the surface of the slab, these signs are defined staple marks, these deformations must still be within the tolerances specified for the realization of silicate glass, soda lime.

It should be noted that the production process will never produce a totally flat, so you will be able to come to create two tipolgi of curvature:

global curvature

localized bending

The glass for the measurement of the bending is placed perpendicular to the ground and kept in vertical position by holding the longer sides, the deformation must be verified lumgo the edges of the glass and along its diagonal, said measurement must be performed at ambient temperature.

For any work on the glass of soda lime silicate please note that after the work hardening should not be cut, sawn, or subjected to processing board so any activities to be undertaken on the document must be strictly carried out the first of quenching; also for the realization of the holes should be taken into considerations slabs with thickness exceeding AI4 mm, the hole diameter is recalled that misses possibly be less than the thickness of the slab

Their ranking will be influenced by:

nominal thickness of the sheet

magnitudes of the plate

diameter of the holes

sleep of the glass sheet

quantity of holes to be played on the plate

Let's talk about the fragmentation tests of the plates the size of the samples to be tested must be: (please refer to the norm) and each specimen shall be struck with a steel tool with tip in a point located to13 mm of the edge and the middle of the longer side of the same specimen.

How to espi of sharp tools and how it should be placed the plate (specimen) is contained in Section 8.3 of the standard.

At the end of the test will be listed in the fragments and tested their measurement, the measurement will be carried out by applying a mask of detection of 50 +/- 1 MMAL be able to verify exactly how many frmmenti will be generated.

Also the characteristics of the glass that will be put to the test:

Optical distortion

Anisotropy

Durability Thermal

Strength

The marking shall indicate that the glass is soda lime silicate must be strictly the following:

name and trademark of the manufacturer

number of European reference standard (in this case EN 12150)
