3 Terms and definitions
For the purposes 01 thIs document, the terms and delinitions given In EN 165:2005 and the following apply.
3.1
transparent
welding curtains, strips and screens that admit vislb4lity to the working place wrihout implrng to be glass clear
4 Requirements
4.1 General
For transparent welding curtains, strips and screens consisting of different materials all requirements for the whole material combination shall be met,
For optical test methods see EN 167.
After preparation, the test specwnens shall be maintained at a temperature of (23 ± 5) °C and relative humidity of (65 ± 10) % for a minimum of 16 h before testing
4.6 Eyelet strength
4.6.1 General
In case of the use of eyelets the described test specifies a method for assessing the seam and eyelet strength of welding curtains. strips and screens. Specimens of materials used for welding curtains. stnps and screens have a weight suspended to them and any damage Is noted.
4.6.2 Test apparatus
The following apparatus is reguired.
a) Bench stand with an attached horizontal damp to hold sheet material 100 i. mm wide evenly in its jaws and allowing the material to hang down freely. The stand shall have a metalic hook of circular cross- section of about 6 mm diameter to attach the sheet material by an eyelet. The stand shall allow to hang a sample freely by at least 600 mm.
b) Minimum weight of 7 kg attached to a metallic hook of circular cross-section of about 6 mm diameter.
c) Clamp as In Item a) but not attached to the stand, with a hole allowing to hang the weight from the damp
using the attached hook as in Item b).
4.6.3 Test specimen
a) Specimen 1: The dimensions of the test specimen shall be 100 mm along the side containing the eyelet under test (if any) and parallel to the seam under test (If any). The other dimension Is not critical and should be between 150 mm and 200 mm. If the sample has no eyelet it should be provided with a punched hole with a diameter of 10mm ±1 mm and 25mm ± 1 mm short of the sides.
b) Specimen 2: The dimensions of the test specimen shall be between 200 mm and 350 mm along the side containing two eyelets under test (if any), the eyelets should be 25 mm ± 1 mm short of the cutting edge. and parallel to the seam under test (if any). The other dimension is not critical and should be between 100 mm and 200 mm measured from the underside of the seam If the sample has no eyelets it should be provided with two punched holes with a diameter of 10 mm ± 1 mm and 25 mm ± 1 mm short of three sides.
c) Specimen 3: The dimension of the test specimen shall be 350 mm long and 100 mm wide, the sample should have no seams or eyelels.
4.6.4 Test procedure
The procedure shall be as follows:
a) Samples with one eyelet under fesf (specimen 1): Attach the specwnen 10 the hook on the stand using the eyelet. Attach the clamp at the lower end of the specimen and apply the weight gradually to the hook of the damp. The weight shall be freely suspended for I mm.
b) Samples With two eyelets under leaf (specimen 2): Attach the specimen to the hook on the stand using one eyelet Apply the weight gradualy to the lower eyelet of the specimen using the attached hook, The weight shall be freely suspended for 1 mm.
c) Samples with no eyelets under test (specimen 3): Attach the specimen to the stand by using the clamp. Attach the other clamp to the lower arid of the specimen and apply the weight gradually to the hook of this clamp- The weight shall be freely suspended for 1 min.
