Key 1 source chamber 2 receiving chamber 3 test specimen 4 valve or welded connection piece fitted with a septum Figure 1 — Typical example of a transmission cell 5.2 Temperature controlled chamber A temperature controlled chamber is used to maintain a constant temperature in the transmission cell during the test. 5.3 Gas chromatograph Various types of gas chromatography columns and detectors are available depending on the test gas. The column type shall be suited to the type of fumigant, and the type of film. The detector shall be suited to the type of fumigant. The precision of the detector and of the column should be taken into consideration in the choice of equipment to be used. The chromatograph shall be calibrated for the given fumigant within its concentration range. It is necessary to determine the limit of quantification (LOQ) for the fumigant being tested. Good laboratory practice should be followed as should the instructions for the gas chromatograph. 5.4 VOC-meter A VOC-meter (volatile organic compound-meter) is used to detect the presence of leaks in the transmission cell. 6 Test specimens 6.1 Test specimens shall be representative of the film, free from wrinkles, folds and pinholes, and of uniform thickness. Test specimens shall be larger than the gas transmission area of the measurement SIST EN 17098-2:2018
