Self-adhesive plates, sheets, film, foil, tape, strip and other flat shapes, not specified in Regulation (EU) 2021/821, having all of the following characteristics: a. A maximum operating temperature exceeding 413,15 K (140 °C) and a minimum operating temperature of less than 233,15 K (-40 °C); and b. Compliant with all of the following, measured in accordance with the standard ASTM E595 or ‘equivalent standards’: 1. A ‘Total Mass Loss’ (TML) equal to or less than 1,0 %; and 2. A ‘Collected Volatile Condensable Material’ (CVCM) equal to or less than 0,10 %. Technical Notes: 1. For the purposes of the control X.C.IX.018, ‘Total Mass Loss’ (TML) is the percentage reduction in specimen mass caused by volatilisation of materials under specified vacuum and temperature conditions according to the standard ASTM E595 or ‘equivalent standards’. Where: M i = initial specimen mass M f = final specimen mass after vacuum exposure 2. For the purposes of the control X.C.IX.018, ‘Collected Volatile Condensable Material’ (CVCM) is the percentage of outgassed volatile material from a test specimen that condenses on a specified collector maintained at controlled temperature. Where: M c = mass collected on the condenser plate M i = initial specimen mass
