identical text or by endorsement, at the latest by August 2016, and conflicting national standards shall
be withdrawn at the latest by August 2016.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent
rights.
This document includes Amendment 1 approved by CEN on 22 November 2015.

following parts:
— Part 1: Definitions and general physical and mechanical properties;
— Part 2: Float glass;
— Part 3: Polished wired glass;
— Part 4: Drawn sheet glass;
— Part 5: Patterned glass;
— Part 6: Wired patterned glass;
— Part 7: Wired or unwired channel shaped glass;
— Part 8: Supplied and final cut sizes;
— Part 9: Evaluation of conformity/Product standard.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria,
Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia,
France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta,
Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland,
Turkey and the United Kingdom.
1 Scope
This Part of this European Standard specifies and classifies basic glass products and indicates their
chemical composition, their main physical and mechanical characteristics and defines their general
quality criteria.
Specific dimensions and dimensional tolerances, description of faults, quality limits and designation for
each basic product type are not included in this Part, but are given in other Parts of EN 572 specific to
each product type:
— EN 572-2 Float glass;
— EN 572-3 Polished wired glass;
— EN 572-4 Drawn sheet glass;
— EN 572-5 Patterned glass;
— EN 572-6 Wired patterned glass;
— EN 572-7 Wired or unwired channel shaped glass;
— EN 572-8 Supplied and final cut sizes;
— EN 572-9 Evaluation of conformity/Product standard.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
float
flat, transparent, clear or tinted soda-lime silicate glass having parallel and polished faces obtained by
continuous casting and floatation on a metal bath
Note 1 to entry: In French called ‘glace’ and in German ‘Floatglas’.
3.2
drawn sheet glass
flat, transparent, clear or tinted soda-lime silicate glass obtained by continuous drawing, initially
vertically, of a regular thickness and with the two surfaces fire polished
Note 1 to entry: Drawn sheet glass covers three products: new antique drawn sheet glass, drawn sheet glass for
renovation and drawn sheet glass with minimum visual faults.
3.3
patterned glass
flat, translucent, clear or tinted soda-lime silicate glass obtained by continuous casting and rolling
3.4
wired patterned glass
flat, translucent, clear or tinted soda-lime silicate glass obtained by continuous casting and rolling
which has a steel mesh welded at all intersections incorporated in the glass during its manufacturing
process
Note 1 to entry: The surfaces can be either patterned or plain.
Note 2 to entry: In German, wired patterned glass with plain surfaces is called ‘Drahtglas’.
3.5
polished wired glass
flat, transparent, clear soda-lime silicate glass having parallel and polished faces obtained by grinding
and polishing the faces of wired patterned glass
3.6
wired or unwired channel-shaped glass
translucent, clear or tinted soda-lime silicate glass, wired or unwired, obtained by continuous casting
and rolling, which is formed into a U shape during the manufacturing process
4 General principles
EN 572-1 shall be read in conjunction with Parts 2 to 9 of this European Standard.
5 Chemical composition
5.1 General
!The basic glass products covered by this European Standard are all manufactured from soda-lime
silicate glass.
The magnitude of the proportions by mass of the principal constituents of soda-lime silicate glass
covered by this European Standard is given in Table 1; see also Annex A:
Table 1 — Magnitude of the proportions by mass of the constituents of soda-lime silicate glass
Constituents Proportion by mass of element
Silicon (Si) 32 % – 35 %
Calcium (Ca) 3,5 % – 10,1%
Sodium (Na) 7,4 % – 11,9%
Magnesium (Mg) 0 % – 3,7%
Aluminium (Al) 0 % – 1,6%
a < 5%
Others
a
Properties other than photometric characteristics shall not be significantly altered by these other
components.
"
5.2 Tint
Body tinted glass is obtained by the addition of suitable materials.
6 Physical and mechanical characteristics
6.1 General characteristics
Conventional numerical values for the physical and mechanical characteristics of basic soda-lime
silicate glass products excluding ‘Characteristic bending strength’ (f ) are given in !Table 2".
g,kk
These values, for normal annealed glass without any further toughening, are not precise requirements
with which the glass shall strictly comply, but are the generally accepted figures for use in calculations
where a high degree of accuracy is not required.
