Without suction box, the number of necessary bags are equal to the number of specimens plus one for blank test. 每个样品使用一个袋子，额外的两个一个用作空白试验另一个装氮气。除了吸气箱，所必需的袋子数量与样品数相等，只增加一个空白试验用的。 2) Attach a silicone tube, 2 3 cm in length, to the end of the Teflon sleeve of each bag with a Teflon cock. If bags without Teflon cock are used, plug the Teflon tube. If bags with one end open are used, seal the opening using plastic clips. 将一个硅树脂管长度方向上2-3cm与带有龙头的特氟龙袖子末端相连。如果袋子不与特氟龙龙头配套使用，就堵上特氟龙管子。如果用一端开口的袋子用特氟龙带子密封开口。3) Connect one end (inlet) of serially connected two activated carbon cartridges to a nitrogen supply line valve and the other end (outlet) to an opening of a 3-way cock, the remaining two openings of the cock being connected to a vacuum pump and a bag.

All of the bags for VOC specimens and for blank test shall be plugged quickly immediately after nitrogen gas is sucked up. 重复上述步骤4）3到5次来彻底抽净。一旦氮气被抽光，所有为VOC试样及空白试验准备的袋子必须快速堵住。6) Fill a bag used as a nitrogen-gas container (nitrogen bag) with nitrogen after the step 5) is finished.在步骤5）完成后用氮气充满用作氮气容器的袋子（氮气袋）4.2 Putting Test Pieces into Bags and Sealing Bags, and Connecting Tubes on Suction Box Notes for sealing bags containing test pieces : 将试样放入袋内，密封袋子，连接管子和吸气箱。密封装有试样的袋子注意：- Use throwaway polyethylene gloves (Saniment or equivalent products) to handle test pieces. Do not touch test pieces with the naked hand. 使用用后及仍的聚乙烯手套（Saniment或等效的替代产品）来拿取试样，请勿用裸手触碰试样。- Unless otherwise specified, a test piece should be placed in a bag with the surface having the largest area kept apart from the bag surface. However, a test piece with an adhesive surface, such as pressure-adhesive tape, should be placed in a bag with the backup paper peeled off and the adhesive surface closely applied to the bag. 除非另有指定，一个试样应该使试样的最大表面远离袋子表面放置到袋内。然而，一个带粘性表面的试样，例如压力-粘性带，应该按照反面远离粘面靠近袋子放置在袋内。1) Place a test piece in a bag, seal and deaerate the bag using a vacuum pump. 放置一个试样到袋内，密封并用真空泵排去袋内气体。 How to seal a bag after a test piece is placed in it (Example): 一试样放入袋中后怎样密封袋子（示例）：Cut off a corner of the bag (3) , place a test piece in the bag, immediately fold back the cut edge of the bag corner inwardly and seal using Teflon tape (4) as shown in Fig. 2 below. 切除袋子一角，将一试样放入袋内，迅速向内翻折袋角的切除边缘并用特氟龙带子密封，如下图2所示。(3) Bags having an opening at a corner may be used. 袋角有开口可能是用过的袋子(4) For sealing the bag, plastic clips may be used in stead of Teflon tape 密封袋子，塑料夹子可以替代特氟龙带子2) Connect the outlet end of an activated carbon cartridge (one of the cartridges used in 4.1) to the nitrogen introduction tube leading through the suction box wall to the bag in the suction box. Nitrogen flow through the cartridge shall be in the same direction as described in 4.1. See Fig. 3. 将一个活性炭滤筒（4.1中所使用的其中一个）的出口端连接到氮气传输管，穿过吸气箱壁至吸气箱内的袋子，氮气流经滤筒方向应与4.1中描述一致。见图3.3) Connect the nitrogen bag to the inlet of the cartridge. 将氮气袋连接至滤筒的进口4) Connect the sampling pump to the outlet of the suction box. 连接收集泵至吸气箱出口5) Place a bag containing a test piece, prepared in the step 1, and connect it to the nitrogen introduction tube so that nitrogen gas can be introduced into the bag. See Fig. 3. 拿一个按照步骤1准备的盛有试样的袋子，将其连接至氮气传输管，于是氮气能够输入袋中。见图36) Before fitting the lid on the suction box, run the sampling pump to stabilize its operation with the flow rate set at 500m/min.在盖上吸气箱盖子之前，先运行收集泵使其稳定工作流动速率在500m/min.7) Connect the sampling pump to the outlet of the suction box, suck up 50.2 of air from the box (it takes approx.10 min) to introduce nitrogen gas in the same volume as the sucked-up air into the bag containing a test piece. Stop the pump, allowing it to be at rest for 2 min, take out the bag from the box and close the cock of the bag, if not provided with a cock, plug the Teflon tube opening. All bags including a blank bag shall undergo this procedure. 将收集泵与吸气箱出口相连，从箱中吸出50.2空气（大约耗时10分钟）导入与吸出空气等体积的氮气到盛有试样的袋中。停止泵的运行，让其静止2分钟，从箱中取出袋子并关闭带上的龙头，如袋上不带有龙头，就堵住特氟龙管的开口。所有袋子中包括一个空白袋，不进行该程序。Nitrogen gas (5) may be introduced into the bags each containing a test piece using an integrating flow meter instead of the suction box provided that impurities in nitrogen gas is sure to be eliminated by a activated carbon cartridge. 氮气（5升）可能导入袋中，每个袋中都盛有试样，使用集流仪器替代吸气箱，提供的氮气中杂质确保被活性炭滤筒清除。4.3 Preparation for Sampling 采样准备1) Connect the Teflon tube of a bag to the sampling pump. 将一个袋上的特氟龙管连接到收集泵2) Start the sampling pump operating (5) and adjust it to the specified flow rate. 开启收集泵工作使其稳定在指定的流动速率 (5) Sampling pump shall be brought into operation 30 min in advance. 收集泵需要提前运行30分钟3-a) Preparation for VOC (other than aldehydes) measurement : Regenerate TENAX tubes by baking them in advance at 250C for at least 6 hours (new tubes) or at least 2 hours (reused tubes). VOC（除了醛）测试准备：通过提前在250C烘焙至少6小时（新管）或至少2小时（再生管）来更新TENAX管。3-b) Preparation for aldehydes measurement : Take out DNPH-Silica cartridges in a necessary number from a refrigerator and leave them at room temperature at least 10 min before starting sampling operation so that they can become as warm as the room temperature. Immediately before measurement, take off a cartridge from the bag and cover the cartridge thoroughly with aluminum foil for shading except on the inlet and outlet ends.醛测试准备：从冷藏室内取出必须数量的DNPH-Silica滤筒，开启收集动作前将它们放置在室温下至少10分钟，这样它们可以变得与室温一样。在即将测试前，拿一个滤筒远离袋子，用铝箔彻底的覆盖滤筒，除了进口和出口端。4.4 VOC Emission and Collection (See Fig. 4.) VOC散发与采集（见图4）1) Place a bag containing a test piece or a blank-test bag, filled with 5 of nitrogen, in an oven heated preliminary to 65C, extend the Teflon tube of the bag through the hole in the top of the oven and make it secured there using a clip. 将已充满5升氮气，装有试样的袋子或空白袋子放置在预热到65C的烤箱内，延伸袋上的特氟龙管穿过烤箱顶部的洞口，并用夹子将其固定。2) Leave the bag in the oven kept at 65C for 2 hours to allow VOC to emit. 将袋子留在烤箱内保持65C 2小时来让VOC释放。3) Remove the plug from the Teflon tube secured on the top of the oven, connect the tube to one end of the TENAX tubes joined together in a row (6) and connect the other end to the sampling pump. Collect 1 of in-bag gas at a gas flow rate of 100 250m/min and another 1 of in-bag gas again at the same gas flow rate with new TENAX tubes in a row. 移除固定在烤箱顶端的特氟龙管堵头，将管子一端与TENAX管在一列上连接为一体，并将另一端与收集泵相连。在100 250m/min流动速率下收集1升袋内气体，再用新TENAX管在一列上收集1升袋内气体。 (6) To avoid VOC breakthrough, two TENAX tubes are connected in a row and the analysis results are reported as the total of the both tubes; however, a single tube may be used if the tube has proved to achieve a collection rate of 95% or higher. 为防止VOC透出，两个TENAX管连接成一列，分析结果记录为所有管子的总数，然而在已证明可以达到采集率95%或以上时也可用一个管子。4) Connect a DNPH cartridge to the Teflon tube leading from the bag and suck up all of the remaining gas (approx. 3) at a gas flow rate of 100 800m/min. Amount of the collected VOC can be calculated from the total amount of collected gas measured using the flow mater. 将DNPH滤筒连接至从袋子引出的特氟龙管，以100 800m/min流动速率吸净残留气体（大约3L）。VOC收集总量可以通过流量计测出的气体收集总量计算得出。5) On completion of sampling, pull off the inlet-side and outlet-side joints of the TENAX tube (or DNPH cartridge), cap the TENAX tubes (or DNPH cartridge). Analysis shall be made on the TENAX tube within 3 days after collection. DNPH cartridge shall be kept in a special bag and stored at 10C or lower until the analysis to be performed within 3 days. 采样完成，拉出TENAX管（或DNPH滤筒）的进口端和出口端接头。盖上TENAX管（或DNPH滤筒）。分析应该在收集后3天内进行。DNPH滤筒应存放在特制袋内，储存在10C或更低的温度下，直至分析在这3天内完成。5.
