可程式高低溫箱標(biāo)準(zhǔn)中規(guī)定的產(chǎn)品結(jié)構(gòu)及外觀要求

The product structure and appearance may be required to program the GDW standards

經(jīng)常瀏覽本站的朋友會發(fā)現(xiàn)，我們關(guān)于可程式高低溫箱標(biāo)準(zhǔn)中規(guī)定的相關(guān)要求，之前一直都是描述的標(biāo)準(zhǔn)起源與術(shù)語定義，以及設(shè)備的一些外部條件和內(nèi)容環(huán)境等，今天，我們一起來了解下標(biāo)準(zhǔn)中對于產(chǎn)品結(jié)構(gòu)與外觀的要求，也希望此篇文章能給正在對可程式高低溫箱型的廣大新老客戶們有一些小小的幫助，標(biāo)準(zhǔn)的就是的：高低溫試驗箱，高低溫交變試驗箱，高低溫交變濕熱試驗箱。

Often visit the site to friends will find, we related requirements may be required to program the GDW standards, until is to define the origin and terminology standard description, equipment and some external conditions and environment, today, we come to know the requirements for product structure and appearance of the standard, also hope this article can give is to programmable high-low temperature box type of the vast number of old and new customers with a little help, the standard is the authoritative: high and low temperature test, high temperature test box, alternating high and low temperature test chamber.

1.首先可程式高低溫箱內(nèi)壁應(yīng)使用耐熱不易氧化和具有一定機(jī)械強(qiáng)度的材料制造。應(yīng)無影響試驗的污染源。

Manufacturing 1 first test box wall should use the heat is not easy to be oxidized and a certain mechanical strength of materials. Should not affect the pollution source test.

2.保溫材料應(yīng)能耐高溫并具有阻燃性能。保溫層應(yīng)有足夠的厚度，能保證試驗箱外部已觸及部位的溫度在高溫試驗時不高于50℃，在低溫試驗及環(huán)境溫度為15℃~35℃、相對濕度≤85%時不應(yīng)有凝露現(xiàn)象。

2 insulation material should resist high temperature and flame retardant properties. Insulation shall be of sufficient thickness, can ensure the test box external has hit parts of the temperature is not higher than 50 ℃ in high temperature test, tests at low temperatures and environmental temperature is 15 ℃ ~35 ℃, relative humidity below 85%, there should be no condensation phenomenon.

3.加熱和制冷器件和冷量不應(yīng)直接輻射在試驗樣品上。

3 heating and cooling device and cooling capacity should not direct radiation on test specimens.

4.工作室應(yīng)設(shè)有觀察窗和照明裝置。

Studio 4 should be provided with an observation window and lighting device.

5.箱門應(yīng)密封良好，密封條應(yīng)有良好的抗高溫老化、耐低溫硬化性能。

The 5 door should be sealed well, seal shall have good resistance to high-temperature, low temperature resistance and hardening property.

6.制冷系統(tǒng)不應(yīng)有漏氣、漏水、漏油缺陷。

6 refrigeration system should not leak, leakage, Water Leakage defects.

7.應(yīng)有放置或懸掛試驗樣品的樣品架。樣品架應(yīng)有足夠的耐高溫、低溫性能。

The sample holder should be placed or hung 7 test samples. The sample frame should have enough resistance to high temperature, low temperature performance.

8.應(yīng)設(shè)有引線孔。

8 shall be provided with a pin hole.

9.外觀涂鍍層應(yīng)平整光滑、色澤均勻，不得有露底、起泡、起層或擦傷痕跡。

9 the appearance of coating should be smooth, uniform color, not to betray a confidence, foaming, layer or scratches.

附：可程式高低溫箱安全和環(huán)境保護(hù)要求：
