22、covered by this European Standard. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

31、the nearest 0,01 mm, one taken at the centre of each side. Measurement shall be by means of an instrument of the calliper micrometer type. 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 2.

New antique sheet glass (3.1) an
35、d sheet glass for renovation (3.2) are classified according to their levels of visual faults. 5.2 Methods of observation and measurement 5.2.1 Optical faults of drawn sheet glass A reticulated screen is observed through the pane of glass to be examined. The screen should have approximately the same
36、dimensions as the pane of glass to be examined. It should consist of a matt black background (reflection coefficient between 0,2 and 0,4) having a network of lines 10 mm thick of a colour contrasting clearly with the background. The network of lines should have the appearance of a wall of bricks who
37、se size is 200 mm 70 mm, each line offset by 100 mm from the lines above and below. The lighting of the screen should correspond to diffuse natural or artificial daylight. Place the pane of glass to be examined vertically 3 m from the screen. Arrange the point of observation 1 m from the glass, keep
38、ing the direction of observation perpendicular to the screen. Arrange the pane of glass to form an angle of 45 with the plane of the screen. Place the pane of glass to be examined vertically 3 m from the screen. Arrange the point of observation 1 m from the glass, keeping the direction of observatio
39、n perpendicular to the screen. Arrange the pane of glass to form an angle of 45 with the plane of the screen. View the screen through the glass and note any disturbing distortions to the pattern. 5.2.2 Visual faults 5.2.2.1 Spot faults Measure the largest dimension (diameter or length) of these faul
40、ts with a micrometer with graduations in tenths of a millimetre. Make note of the number, dimensions and concentration of spot faults. DIN EN 572-4:2012-11EN 572-4:2012 (E) 8 5.2.2.2 Linear/extended faults The glass pane to be examined is illuminated in conditions approximating to diffuse daylight a
41、nd is observed in front of a matt grey screen. Place the pane of glass to be examined vertically in front of the screen and parallel to it. Arrange the point of observation 2 m from the glass, keeping the direction of observation normal to the glass surface. View the pane of glass, and note the pres
42、ence of visually disturbing faults. 5.3 Acceptance levels The acceptance levels are summarised in Tables 4 and 5: Table 4 Summary of acceptance levels for new antique drawn sheet glass and for drawn sheet glass for renovation Faults Acceptance criteriaOPTICAL Not applicable VISUAL 1 Spot faults 1.1
