BS EN 572-5-2004 pdf download.Glass in building Basic soda lime silicate glass products Part 5 : Patterned glass.
This Part of this BS EN 572 specifies dimensional and minimum quality requirements (in respect of visual
and pattern faults) for patterned glass as defined in EN 572-1, for use in building.
This Part of this BS EN 572 applies only to patterned glass supplied in rectangular panes and in stock sizes.
EN 572.8 gives information on patterned glass in sizes other than those covered by this Part.
2 Normative references
This European Standard incorporates by dated or undated references, provisions from other publications. These normative references are cited at the appropriate places in the text, and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies (Including amendments).
EN 572-1:2004, Glass in building — Basic soda lime silicate glass products — Part 1: Definitions and general physical and mechanical properties.
3 Terms and definitions
For the purposes of this European Standard, the terms and definitions given in EN 572-1:2004 and the following apply.
3.1
length, H, and width, B
defined with reference to the direction of draw of the glass ribbon as shown in Figure 1.
NOTE The maximum stock sizes available depend on the manufacturer and the pattern.
3.3
visual faults
faults, which alter the visual quality of the glass. They include spot faults, linear/extended faults and pattern faults
3.4
spherical or quasi-spherical spot faults
spot faults whose larger dimension is less than or equal to twice the smaller dimension
3.5
elongated spot faults
spot faults whose larger dimension is more than twice the smaller dimension
3.6
linear/extended faults
faults, which can be on or in the glass, in the form of deposits, marks or scratches which occupy an extended length or area
3,7
pattern faults
deviations of the pattern relative to a reference. e.g. line or straight edge
deviation of the pattern
deviation, x, of the pattern
4 Dimensional requirements
4.1 Thickness
4.1.1 General
The actual thickness shall be the average of four measurements, taken to the nearest 0,01 mm, one taken at the thickest and closest point to the centre of each side. Measurement shall be by means of an instrument of the plate gauge type with a diameter of 50 mm ± 5 mm.
NOTE The mechanical resistance of patterned glass is a function of the pattern as well as the thickness.
4.1.2 Tolerances
The actual thickness rounded to the nearest 0,1 mm shall not vary from the nominal thickness by more than the tolerances shown in Table 1.
If their length is ≤ 4.0 mm. they are acceptable without restnction.
If their length Is > 4,0 mm and ≤ 25,0 mm, they are acceptable if the sum of the lengths is ≤ 100 mm in any 1 m x 1 m area.
They are not acceptable if the length is > 25,0 mm.
C) Elongated spot faults of width > 2,0 mm.
If the larger dimension is ≤ 8,0 mm, they are acceptable up to 2 in any 1 m x I m area. They are not acceptable if the larger dimension is > 8,0 mm.
5.3.2 Linearlextended faults
The number of allowable faults is an average of 0.05 faults in 20 m2 of glass related to at least 20 tonries.
5.3.3 Pattern faults
The deviation of the pattern, x, (see Figure 3) shall not exceed 12 mm per metre.
6 Designation
Patterned glass in compliance with this standard shall be designated respectively by type:
tint (manufacturers reference) or clear:
pattern (manufacturer’s reference):
nominal thickness in mm:
nominal length, H, and width, B. in mm; reference to this Part of this standard.
EXAMPLE
Patterned glass, pattern reference PATTERN’, dear, thickness 4 mm, length 4,50 m, width 1,60 m, intended for use in buildings, is designated as follows:
Patterned glass – EN 572-5 – clear ‘PATTERN’, 4 mm, 4 500 mm x 1 600 mm.BS EN 572-5-2004 pdf download.
