I live in beautiful urban Hangzhou, there is a small princess of 3 years old in the home. Because want,give the child a better growing environment, I am two years ago proceed with present new home, and be at the beginning of this year when, finished the home in decorate. Although decorate when those who choose is environmental protection material, do not pass or can certain formaldehyde is released. Because fear formaldehyde exceeds bid, still dare not let the child be entered all the time. This favour obtains SGS formaldehyde to detect the experience qualification of the box, also satisfied me to want the think of a way of circumstance of the formaldehyde in accurate knowledge home. Contact SGS actually already very old, because of working reason, need often tests all sorts of products through SGS, in my eye, SGS is one is compared detect professionally orgnaization, and can win client of a lot of abroad what detect as a result approbate, accordingly my formaldehyde to this detects special also expect
The formaldehyde that experiences this detects the box opens Guo Shunfeng express to undertake delivering goods directly by SGS, so have more than is needed how many time, the product arrived in my hand, of the product packing is color print carton, the design compares simple palpability, top left corner is the Logo of SGS, and the product was made clear on the box be indoor air formaldehyde detects service sampling box.
Those who pack is rear, made clear the norms of the product, what experience this is the product of two outfit. And used a paragraph of written language, undertook introductory to SGS group.
The interior that pack, besides used aluminum foil bag besides two vacuum-packed products, still have papery sampling manual, to assure the accuracy of the test, this specification suggests strongly to be read seriously.
Sampling box is external aluminum foil bag is thicker, ravel observe through naked eye before bag, bag is in vacuum condition and not flat
The coping of bag, or so both sides has a little gap to go to the lavatory tear apart bag. And can be judged through the trace, rip buccal lower part, have one each seal.
After because detect,ending, need assembles the product a bag to undertake afresh sealed, must undertake sealing off from mouth place so, and do not want have bag discarding. If in case discarded, had better be to be before test end, find can replace use sealed bag.
The volume of sampling box is not large, compared with the mouse for slightly small, crust used white plastic material is qualitative, and upper part has the Logo of SGS.
The front of sampling box has the structure of slip lid type, will control the active material of sampling box interior and indoor airy contact from this.
The reverse side of sampling box has yard of a 2 dimension, this is the identification code that has exclusive grade, the operation of all later period is basic this encode undertakes.
Carry code of this 2 dimension, pay close attention to date of public of SGS wisdom life, can begin the technological process of sampling.
The accretion that passes public mark box, undertake binding deciding with the box of the test, and be in a room sealed after 9 hours, can undertake sampling.
Use before collecting a box, need closes door window 9 hours first first, have comparative sex to yield the result of the test, in the process of the test, I also use the formaldehyde data during the formaldehyde instrument mobile phone of family expenses checks. The formaldehyde instrument that I use is the sensor that used British Dart, this also is a more outstanding sensor. Before closing door window, measure so that the formaldehyde content inside house is 0.021mg/m3
Close in door window after 9 hours, begin to have the move of formaldehyde test, enter public order, fill in place, the position, sampling environment, the information such as environmental photograph, began to start the program of sampling. Because now is summer, actual indoor temperature has three degrees, to obtain the condition of 22-28 ℃ and humidity 40-80% , I press the proposal that reflects a manual, undertake modulatory through opening the air conditioning of the room, and be in the program also cancel the option that chose air conditioning
Before sampling, still need to do a work, slip the over cap before sampling box namely below
Slip after next cap, can see the surface was bestrewed pick air hole, through here the formaldehyde in internal active matter and air is contacted, any analysises that pass a lab, computation gives final formaldehyde to be worth.
What still need an attention additionally is the placement of the box, need leaves a wall 0.5 meters of above, from ground 0.5-1.5 rice between, such ability make sure first-rate collects the result, my general collects a box to place waving on the window, accorded with this requirement.
The process that collecting in the begining, because had closed door window reason of many hours, the formaldehyde value inside house should compare ventilated circumstance to fall to go up high apparently a lot of, this is to use formaldehyde appearance to measure the eventuate 0.059mg/m3 that go out
In collection process, small order can undertake timing, in the rest 30 minutes when and when collecting an end, also can information undertakes remindful. Additionally I also set alarm clock by oneself, placed time to overdo.
After collecting 6 hours, the formaldehyde value that formaldehyde appearance indicates is 0.071mg/m3. Collected a process to end at this moment.
At this moment I build the slip lid that collects a box afresh on, and will collect a box load original close envelope to undertake sealed, prevent to collect a box to continue to contact air again, the measurement with ultimate effect result.
After measuring an end, of small order lower part " answer freely send " key-press can illume, ending because of the test had been in the evening at 10 o'clock, so I chose to undertake answering sending the following day, collect a box to need to be answered inside 7 days according to the specification send, if when cannot answer the word that send for a short while, need will collect a box to undertake cold storage. Can make an appointment directly on small order suitable abundant comes to take, and freight also is arrive pay, after the operation ends, I also received the information that suitable abundant accepts the order.
After collecting a box to arrive at a lab, I also received public date to push sent message. According to the specification, the analysis needs 3 weekday as a result, because of what receive that day is on Friday, eliminate on the weekend, I got test result on time in Tuesday.
The test provided a detailed test report as a result, the eventuate 0.04mg/m3 of the test, our country is worth to the bounds of formaldehyde is 0.1mg/m3, so the environment inside my house still accords with a standard. The likelihood has some of person to be able to have doubt, the outcome of the result that why checks and formaldehyde appearance is different? This main reason is the detector gets more easily environmental influence, and fluctuate compare big, similar I appearance of such family expenses formaldehyde, it is used more outstanding chip, the result still serves as reference merely. The major that SGS regards a world-class as detects orgnaization, to the result of the test, my individual still approbates quite.
Summary and individual viewpoint:
The indoor formaldehyde of SGS checks a service, detect through mailing box, proper motion checks and the user sends detected kind, go up compared with market other measure formaldehyde service, more convenient. At the same time because SGS is one extraction bound 500 detect by force orgnaization, and did not think other the service that eliminates formaldehyde was bound like the company that surveys formaldehyde, accordingly I trust his home to check domestic result more. What compare the formaldehyde appearance that has housekeeping money of course is convenient and rapid for, SGS formaldehyde checks a process or time of on need flower one day undertakes. Both nevertheless mix like bear's paw the fish is same, convenient hard accurate, need the time on the flower accurately, nevertheless the individual thinks, do not cross the health for family, on the flower one day of time goes checking the formaldehyde content in the home, still comparative worthiness.
