All re-inspection qualified you can determine the qualified products. Appendix a (normative appendix) small environmental test chamber method A.1, a small environmental test class small environmental testing consists of sealed cabin, air filter, air temperature and humidity control and monitoring system, air flow, flow control decoration, air sampling system components. As shown in Figure A.1. 1-air inlet; 2-air filter; 3-air temperature and humidity regulation system; 4-5-air flow regulator air flow regulator; 6-sealCabin; 7-air speed and air cycle of control device; 8-temperature and humidity sensor; 9-temperature and humidity of monitoring system; 10-exhaust mouth; 11-air sampling of set tracheal it is simulation indoor environment, in must of test conditions Xia (temperature, and humidity, and air velocity and air exchange rate,), will sample exposure in cabin within, continued must time Hou, collection cabin within harmful gas. A.2, small environmental test chamber test methods–air temperature 23 ¡ã c ¡À 1 ¡ã c; 50% ¡À 5.0%;—-air relative humidity air 1.0h-1;–air velocity exchange rate 0.1M/s~0.3M/s. A.3, sampling, packaging and preparing of test specimens A.3.1, A.3.1.1 for sampling, sample from regular party production, machine under no more than 30 days, drawn by inspection of packaging products. A.3.1.2, in volume products in the sample, from the head-end 2m, interception of 1m2 sample for at least two blocks in the middle. A.3.1.3, tile needlepoint rugs randomly from the batch product box. A.3.1.4 randomly from the batch product, Carpet adhesive a barrel. A.3.2, packaging and needlepoint rugs production direction of A.3.2.1, constant volume sample into volume, rope fastening, inert sample should be wrapped in airtight packaging bag. For example, you can sample package aluminum foil, enclosed in a gas-tight polyethylene bag, each bag can only load a sample. A.3.2.2, from selected samples to install inside the bag, shall not exceed 1h. And immediately send the test Chamber. A.3.2.3 package, sample tags should be more marked product type, manufacturing date, batch number and manufacturer name. A.3.3 A.3.3.1, and sample, the client samples reach the laboratory as soon as possible after the examination. A.3.3.2, needlepoint rugs and needlepoint rugs cushion edge from the samples must be at least 100mm of the sample, according to the requirements of area of interception of a specimen, the material/cabin load ratio of 0.4m2/M3. A.3.3.3, tile needlepoint rugs should be in the middle of the box parts take samples. Sample A.3.3.4, Carpet adhesive: adhesive coating simulation Board (glass or stainless steel), its material/cabin load ratio of 0.012m2/M3 coating density (mg/cm2) in accordance with the manufacturer’s instructions for use. A.4, space test program A.4.1, test preparation A.4.1.1, test forward cabin cleaning, first alkaline cleaning agent cleaning Chamber wall, then scrubbed with deionized water or distilled water twice, and then purification. A.4.1.2 within and under the test conditions to spaces after leads to purification of clean air. A.4.1.3, in tests before the start of monitoring test conditions such as temperature and humidity, air velocity, air tightness, cabin air background concentrations should be below the detection limit analysis method. A.4.1.4, client sample should blanket face tile on bilge, air flow from the specimen surface evenly through the air. A.4.2, test end test specimen under test conditions in the cabin when emission duration is 24h. A.5, small pilot cabin air sampling method of sampling in accordance with the provisions of ISO16017-1:2000.
