防爆產品認證的基本流程是怎么樣的？

防爆產品認證流程根據認證類型的不同而有所區別。目前國內的防爆認證主要分為防爆3C認證和防爆合格證認證。 防爆3C認證是針對納入國家強制性產品認證目錄的防爆電氣設備，采取“產品檢測+工廠評審”的模式，既要做產品的型式試驗，也要做工廠現場評審。而防爆合格證認證則是針對防爆3C目錄之外的產品，只需進行產品檢測，檢測合格……

ATEX防爆認證的產品范圍

ATEX防爆認證主要適用于可能產生易燃易爆環境的設備和保護系統。這些產品范圍廣泛，包括但不限于以下幾類： （1）電氣設備：如電機、開關、照明設備等，這些設備在易燃易爆環境中使用時需要符合特定的防爆要求。 （2）機械設備：一些在易燃易爆環境中運行的機械設備，如攪拌器、泵等，也需要進行ATEX認證。 （3）保護系統：用于防止爆 炸發生或限制爆 炸影響的保護系統，如防爆墻、抑爆裝置等。 （4）Ex元件：擬用于易燃易爆環境的防爆Ex元件。 但是，在2014/34/EU 指令里也明確指

防爆認證等級IIB和IIC的區別

防爆認證等級IIB和IIC是防爆電氣設備在易燃易爆氣體環境中的分類，它們之間存在一些關鍵區別。 首先，IIB和IIC都屬于II類防爆設備，這類設備適用于除煤礦外的其他易燃易爆氣體環境，如石油化工、天然氣等行業常見的可燃氣體和蒸汽環境。對于這類設備，根據易燃易爆氣體的特性會進一步細分為不同的組別，如IIA、IIB、……

防爆設備需要什么防爆證書？
