14、be used if pre-cleaned 10-L PVF Tedlar bags are not available for purchase: 1. Heat the bag to100 C for 24 hours. 2. After heating the bag, install the sample port, seal, and evacuate the bag. Evacuation of the bag should take no longer than one minute and maintain consistent evacuation time from ba

15、g to bag. 3. Test bags should be cleaned in lots. Mark the bags to insure from the same lot. 4. Each lot of bags shall be comprised from the same material roll, heated, sealed, and evacuated as a group. Conditioning of Materials and Specimen Preparation Note: Whenever handling the specimens, samples

16、, and sampling bags, nitrile gloves shall be worn. 1) Cut 10 x 20 cm test specimens and begin conditioning for 14 28 days at 23 2 C and 50% relative humidity and pressure. 2) After conditioning for 14 28 days, the test specimens must either be tested immediately or placed in a new polyethylene (PE)

17、coated aluminium bag, or wrapped tightly in silicone-free aluminum foil then placed in a new PE bag, until testing. Note: Any samples bagged and not immediately tested should go back in the conditioning room/chamber at 23 2 C and 50% relative humidity until testing begins. Note: Suppliers shall subm

18、it a minimum of two (2) specimens per test. One (1) specimen per test will be used as backup. Samples should not be exposed to air in contaminated locations or locations with poor air quality (such as paint shops, etc.) The entire surface area of the test specimen should be exposed to air (i.e. leat

19、her should not be folded to itself) 10 L Sample Bag Procedure NOTE: Sampling procedure steps 1 10 shall be performed concurrently, without interruption. 1. Use conditioned TD tubes and a properly stored DNPH cartridge. The sampling system transfer lines shall be as short as possible. 2. Record the s

20、pecimen dimensions (cm) and mass (g). Open the sampling bag. Place the specimen into the sampling bag. Immediately seal the sampling bag. Photograph the specimen in the bag. Note: The specimen shall be put into the bag with the “A” surface facing up. The “A” surface is defined as the surface exposed

21、 to the customer in a vehicle. 3. Evacuate until all the air is removed from the bag (approximately 10 seconds). 4. Leak check the bag with a vacuum gauge. 5. Fill the bag with 6.0 L 0.2 L of N2. 6. Place the sample bag into the pre-heated oven at 65 2 C. Each bag shall be positioned flat on the rac

22、ks and attach to the sampling assembly. The bag is not allowed to touch the inner side of the oven or other bags. 7. Heat the sample for 2 hours 2 minutes.

24、ted mass and bag concentrations 9. Collect the evolved samples from the sample bag. 10. Once sampling is completed, remove the TD tubes and DNPH cartridge. Cap and seal the TD tubes. Place the DNPH cartridge inside a sealed aluminized Mylar bag. Store the sealed TD tubes and DNPH cartridge at 4 2 C.

25、 The analysis of the TD tubes and DNPH cartridge must be performed within 7 days. 11. Analyze the TD tubes using the following references: a.
