maksymalna lub minimalna (granica zawartości) zawartośc gazu palnego dla zapłonu Explanation: Flammability of Gases – Definition and Measurement The Globally Harmonized System of Classification and Labeling of Chemicals (GHS) defines a flammable gas as a gas having a flammable range in air at 20°C (68° F) and at a standard pressure of 101.3 kPa (1 atmosphere). Similar definitions of a flammable gas are found in DOT, IATA and IMDG regulations as well as in the Aerosol Dispensers Directive (2008/47/EC). Gases are considered to have a flammable range if they exhibit vapor flame limits, i.e., a lower flame limit (LFL) and an upper flame limit (UFL). The LFL is the leanest concentration of the gas in air that will support combustion and the UFL is the richest concentration in air that will support combustion. ,Two of the commonly-used tests to determine vapor flame limits are ASTM E-681 and International Standard ISO 10156. A brief description of those methods appears below. Solstice® Propellant was tested according to both methods and found not to have a flammable range under the prescribed test conditions of 20°C and one atmosphere. It was also tested under EC Testing Method A11: Flammability of Gases (E.U.) and did not have a flammable range. Solstice® Propellant is, therefore, classified as a nonflammable liquefied gas by GHS, DOT, IATA and IMDG criteria. chrome-extension://efaidnbmnnnibpcajpcglclefindmkaj/viewer.html?pdfurl=https%3A%2F%2Fwww.crcind.com%2Fcrc%2FHFO-1234ze.pdf&clen=320069&chunk=true Wartość maksymalnej zawartości gazu palnego (Tci) znajduje się w tabeli 2 normy ISO 10156 (wydanie z dnia 15 grudnia 1990 r.) lub normy PN-EN 720-2:2000. https://www.prawo.pl/akty/dz-u-2002-140-1172,16978789.html |
