- Part 20.Equipment with equipment protection level (EPL) Ga.
This Part is drafted in accordance with the rules given in GB/T 1.1-2009.
This Part is Part 14 of GB 3836.
This Part replaces GB 3836.14-2000 "Electrical apparatus for explosive gas
atmospheres - Part 14.Classification of hazardous areas". Compared with GB
3836.14-2000, the main technical changes are as follows.
- ADD explosion hazard of flammable mist released by high flash point liquids
under pressure (see Annex D);
- In the release rate, give many thermodynamic calculation equations for the
estimation of the release rate of liquids and gases (see A.3).
This Part, using translation method, is identical to IEC 60079-10-1.2008
"Explosive atmospheres - Part 10-1.Classification of areas - Explosive gas
atmosphere" (English edition).
This Part was proposed by China Electrical Equipment Industry Association.
This Part shall be under the jurisdiction of National Technical Committee 9 on
Explosion Protected Electrical Apparatus of Standardization Administration of
China (SAC/TC 9).
Main drafting organizations of this Part. Nanyang Explosion Protected Electrical
Apparatus Research Institute, China National Quality Supervision and Test
Centre for Explosion Protected Electrical Products, Helon Explosion-proof
Electric Co., Ltd., Shenzhen Jinming Technology Co., Ltd., Sunleem

The previous editions of the standard replaced by this Part were released as
follows.
- GB 3836.14-2000.
1 Scope
This Part of GB 3836 is concerned with the classification of areas where
flammable gas or vapour or mist hazards (see Notes 1, 2 and 3) may arise and
may then be used as a basis to support the proper selection and installation of
electrical equipment for use in a hazardous area.
2 Normative references
The following documents are indispensable for the application of this document.
For the dated references, only the editions with the dates indicated are
applicable to this document. For the undated references, the latest edition
(including all the amendments) are applicable to this document.
GB/T 2900.35-2008 Electrotechnical terminology - Equipment for explosive
atmospheres [IEC 60050(426).2008, IDT]
3 Terms and definitions
For the purposes of this document, the terms and definitions given in GB
3836.1-2010 and the following apply.
4 General
Subsequent to the completion of the area classification, a risk assessment may
be carried out to assess whether the consequences of ignition of an explosive
atmosphere requires the use of equipment of a higher equipment protection
level (EPL) or may justify the use of equipment with a lower equipment
protection level than normally required.
5 Area classification procedure
The basic elements for establishing the hazardous zone types are the
identification of the source of release and the determination of the grade of
release.
6 Ventilation
Ventilation can be accomplished by the movement of air due to the wind and/or
by temperature gradients or by artificial means such as fans. So, two main types
of ventilation are thus recognized.
The availability of ventilation has an influence on the presence or formation of
an explosive gas atmosphere and thus also on the type of zone.
7 Documentation
Where the topography of an area influences the extent of the zones, this should
be documented.
Annex A
(Informative)
Examples of sources of release
The following examples are not intended to be rigidly applied and may need to
be varied to suit particular process equipment and situations. It needs to be
recognised that some equipment may exhibit more than one grade of release.
