ATEX certification is the use of the name of the two is used to control the explosive environment instruction, one is the manufacturer's instructions, the other one is equipment user instructions. This two instructions include: directive 99/92 / EC (also called ATEX certification 137 or ATEX certification work instruction) and directive 2014/34 / EU (also called ATEX certified equipment instruction), and replace the old directive 94/9 / EC

The applicability of this instruction equipment particularly big, generally including fixed offshore platform, petrochemical plants, flour mills and other places where there may be a potential explosive environment suitable equipment. The directive applies to the safe use of the necessary components, as well as within the scope of direct use of safety equipment favorable safety device. These devices can be on the outside of the potentially explosive environment.

ATEX explosion-proof certification is compulsory requirements of explosion-proof products into the eu market, so to enter the eu market for explosive product must follow the ATEX directive, achieved ATEX certification, the products labeled with ATEX.

ATEX certification as EX explosion-proof, have division, to be used according to the danger zone, choose the ATEX directive requirements of the equipment

Explosive areas define China standard

Gas, steam, the mist

(Class I or Class G) under normal circumstances, the continuous or long time existence of sites with explosive air mixture 0 area

Under normal circumstances, the possible sites with explosive air mixture 1 area

The difference between 2 area

Dust or fiber

(Class II/III or Class D) under normal circumstances, explosive dust or combustible fibers in mixture with air of 20 straight or long time place area

Under normal circumstances, a mixture of explosive dust or combustible fibers and air zone 21 possible places

Under normal circumstances, explosive dust or the mixture of combustible fibers and the air is not possible, only in abnormal situations, occasionally appear place 22 area or a short time

ATEX certification and IECEx certification in common:

1, for potentially dangerous for the dangerous sites and the necessary requirements of equipment

2, ATEX certification and accreditation have IECEx quality guarantee system. For high-risk category of explosion-proof products, complete quality system certification, must be applied to the quality system is mainly based on ISO 9001 and the design of explosion-proof products, manufacturing and additional requirements, test performed by the certification body.

The main difference between ATEX certification and IECEx certification:

1, ATEX certification is driven by law, the IECEx certification by the driver. Legal to use in dangerous places all the electrical and electrical devices ATEX certification is required. But the only electrical equipment in dangerous places to need IECEx certification.

2, ATEX certification valid only in the European Union and the IECEx certification is international, gm in 54 countries. And explosion-proof products exports to the eu countries currently only recognize ATEX certificate, does not recognize IECEx certificate.

3, in the aspect of standard, is not compulsory
