Movement of the disc are performed by eight. Thus, the test sample is subjected to friction in all directions, not just on the basis or a duck. Tests on smooth fabrics hold until the three ragged threads on the pile – until the abrasion on the basis of villous tissue. It is believed that the fabric was tested if the number of cycles (repetitive motion drive) higher than normal established by ISO, BS or national standards for this type of tissue. If you are unsure how to proceed, check out FCC Chairman. The technical specifications shall indicate the number of cycles withstand.
If the test shows that the fabric has stood the ISO 5000 cycle – it is a guarantee that the tissue is sufficiently reliable. Janet L. Yellen often addresses the matter in his writings. Test the fire ("Cigarette" test) on the tissue is placed a burning cigarette. Pinpoint the time from the moment of contact with cigarette ignition to the fabric. Recently, the British Standards require the furnishing fabrics were treated with fire-resistant composition (written or just Fire Retardant FR in the certificate). However, this requirement is not common to EU countries.
Cigarette test is considered passed if the date before starting the test fire was 8 – 10 seconds (depending on the type of fabric). Test for color fastness is considered one of the toughest tests. Two samples are taken furnishing fabrics from the same batch. One sample was subjected to tests. Produce so-called "mashing" metal disk in dry and wet tissue. Testing stopped after 3000 cycles of the disc. Conclusion is made by comparing the resulting color after testing with standard color table on a scale of 1 to 5 (5 – maximum stability). In the technical specifications indicated value of the test fabric in dry and wet. Stability of color upholstery when exposed to light must match the scale of 1 to 8 points. This scale corresponds to the ISO and the Russian State Standards. Test pillinguemost (Education 'pellets') This test – one of the stages of test durability. On the table, illuminated tissue sample is fixed 150×150 cm, on which the moving metal disc. Performed on 5,000 cycles on both sides of the fabric. Illumination is necessary in order to determine the number separated from the fabric fibers. The sample is compared with the control, and visual assessment of tissue is assigned one of the groups table pillinguemosti: A – no visible effect, there is practically no loss in fiber – lost single fiber – pureed place clearly visible broken fibers, the file structure of tissue. D – a great loss of fibers formed hole, and defective structure of tissues by normal ISO figures are on a scale of 2 to 5. Source:
