8 Marking 标志
插头插座量规Gauges for plugs and sockets：
IEC60884|GB2099|VDE0620 测试设备Testing equipments：
8.1 Accessories shall be marked as follows:
− rated current in amperes;
− rated voltage in volts;
− symbol for nature of supply;
− manufacturer's or responsible vendor's name, trade mark or identification mark;
− type reference which may be a catalogue number;
− first characteristic numeral for the degree of protection against access to hazardous parts and
against harmful effects due to ingress of solid foreign objects, if declared to be higher than 2, in
which case the second characteristic numeral shall also be marked;
表示防止接触危险部件和防止固体杂质侵入的保护级别的符号，如果该级别大于 IP 2X 的
− second characteristic numeral for the degree of protection against harmful effects due to ingress
of water, if declared to be higher than 0, in which case the first characteristic numeral shall also
表示防止水分有害侵入的保护级别的符号；如果保护级别大于 IP X0的话，这时还必须给
出防止固体杂质侵入的保护级别，即使该级别不大于 IP 2X。
If the system allows plugs of a certain IP rating to be introduced into socket-outlets having another IP
rating, attention should be drawn to the fact that the resulting degree of protection of the combination
plug/socket-outlet is the lower of the two. They shall be stated in the manufacturer's literature related
to the socket-outlet.
如果系统内允许特定 IP 等级的插头插入到不同 IP 等级的插座时，制造商必须提醒在此情况
下，系统的 IP 等级会降为兩者之中较低的 IP 等级。此项陈述必须在插座相关說明文件中载
NOTE 1 The degrees of protection are based on IEC 60529.
注1︰关于IP等级的說明，參見 IEC 60529。
In addition, socket-outlets with screwless terminals shall be marked with the following:
− an appropriate marking indicating the length of insulation to be removed before the insertion of
the conductor into the screwless terminal,
− an indication of the suitability to accept rigid conductors only, for those socket-outlets having this
NOTE 2 The additional markings may be put on the socket-outlet, on the packaging unit and/or given in an instruction sheet
which accompanies the socket-outlet.
8.2 When symbols are used, they shall be as follows:
NOTE 1 Details of construction of symbols are given in IEC 60417-2.
NOTE 2 In the IP code the letter "X” is replaced by the relevant number.
NOTE 3 Lines formed by the construction of the tool are not considered as part of the marking.(2006-05 deleted)
The marking for the nature of supply shall be placed next to the marking for rated current and rated
NOTE 4 The marking for current, voltage and nature of supply may be, for example, as follows:
16 A 440 V~ or 16/440~ or 440/16
8.3 For fixed socket-outlets the following marking shall be placed on the main part:
− rated current, rated voltage and nature of supply;
− either the name, trade mark or identification mark of the manufacturer or of the responsible
− length of insulation to be removed before the insertion of the conductor into the screwless
terminal, if any;
− the type reference, which may be a catalogue number.
NOTE 1 The type reference may be the series reference only.
Parts such as cover plates, which are necessary for safety purposes and are intended to be sold
separately, shall be marked with the manufacturer's or responsible vendor's name, trade mark or
identification mark and type reference.
NOTE 2 Additional type references may be marked on the main part, or on the outside of the associated enclosure.
NOTE 3 The term "main part" means the part carrying the socket contacts.
The IP code, if applicable, shall be marked so as to be easily discernible when the socket-outlet is
mounted and wired as for normal use.
Fixed socket-outlets classified according to item b) of
be visible after installation unless they have an interface configuration which is different from that
used in normal circuits.
NOTE 4 In the following countries an orange triangle is required by the national installation rules: CA, US.
8.4 For plugs and portable socket-outlets the marking specified in 8.1, other than the type reference, shall
be easily discernible when the accessory is wired and assembled.
Plugs and portable socket-outlets for equipment of class II shall not be marked with the symbol for
class II construction.
NOTE The type reference of rewirable portable accessories may be marked on the inside of the enclosure or cover.
8.5 Terminals intended exclusively for the neutral conductor shall be indicated by the letter N.
规定只用于中线的端子应标上大写字母 N 进行識别。
Earthing terminals for the connection of the protective conductor shall be indicated by the symbol .
These markings shall not be placed on screws, or any other easily removable parts.
NOTE 1 "Easily removable parts" are those parts which can be removed during the normal installation of the socket-outlet or
the assembly of the plug.
NOTE 2 Terminations in non-rewirable accessories need not be marked.
Terminals provided for the connection of conductors not forming part of the main function of the
socket-outlets shall be clearly identified unless their purpose is self-evident, or indicated in a wiring
diagram which shall be fixed to the accessory.
The indication of such terminals may be achieved by
− their being marked with graphical symbols according to IEC 60417-2 or colours and/or
alphanumeric system, or
使用 IEC 60417-2 的符号或是以颜色和/或字母數字系统进行識别；或
− their being marked with their physical dimensions or relative location.
Leads of neon or indicator lamps are not considered to be conductors in the context of this subclause.
8.6 For surface-type mounting boxes forming an integral part of socket-outlets having an IP code higher
than IP20, the IP code shall be marked on the outside of its associated enclosure so as to be easily
discernible when the socket-outlet is mounted and wired as in normal use.
对于 IP 20 以上构成插座不可分割一部分的明装埋入式安装盒，必须在附属的外壳外标上 IP
8.7 It shall be indicated either by marking or in a manufacturer's catalogue or instruction sheet in which
position or with which special provisions (for example, box, type of mounting surface, plug, etc.) the
declared degree of protection of flush-type and semi-flush-type fixed socket-outlets having an IP
code higher than IPX0 is ensured.
插头等等）來保证埋装或暗装固定式插座所宣称的防护等级是高于 IP X0 的等级。
Compliance is checked by inspection.
8.8 Marking shall be durable and easily legible.
Compliance is checked by inspection and by the following test.
The marking is rubbed by hand for 15 s with a piece of cloth soaked with water and again for 15 s with
a piece of cloth soaked with petroleum spirit.
用蘸水的布条标志 15s，然后用蘸汽油的布条擦拭标志 15s。
NOTE 1 Marking made by impression, moulding, pressing or engraving is not subjected to this test.
NOTE 2 It is recommended that the petroleum spirit used consists of a solvent hexane with an aromatic content of maximum
0,1 volume percentage, a kauributanol value of approximately 29, an initial boiling point of approximately 65 , a dry ℃
point of approximately 69 and a density of approximately 0,68 g/cm ℃ 3.
