Add the following IEC standard:
IEC 60999-1:1999, Connecting devices – Electrical copper conductors – Safety requirements
for screw-type and screwless-type clamping units – Part 1: General requirements and
2 2
particular requirements for clamping units for conductors from 0,2 mm up to 35 mm

conductors suitable for screwless terminals.
Page 29
9 Dimensions and compatibility
9.6
Replace, on page 35, the first and second paragraphs of Subclause 9.6 by the following text:
Non-standardized appliance couplers which do not refer to the dimensions specified in the
standard sheets are acceptable, but only if they provide a technical advantage and do not
adversely affect the purpose and safety of appliance couplers complying with the standard
sheets, especially with regard to interchangeability and non-interchangeability.
Non-standardized appliance couplers, however, shall comply with all other requirements of
this standard as far as they reasonably apply.
Change “Note 1” to “Note”.
Insert after the Note the following normative text:
Small deviations from the dimensions as specified in the standard sheets, which give the
impression of a standardized coupler and lead to confusion with standardized appliance
couplers, are not allowed.
Change Notes 2 and 3 into normative text.
Add, at the end of the subclause, the following new paragraph:
It shall not be possible within a given system for a connector and associated appliance inlet to
make improper connections other than the intended position or partial connections causing
deformation which can impair the further use of the appliance.
Compliance is checked by manual test.

12 Terminals and terminations
Renumber the first three paragraphs as “12.1 General”.
Delete the existing subtitle “12.1 General”.
Delete existing Subclauses 12.1.1, 12.1.2 and 12.1.3.
Add the following new Subclause 12.2:
12.2 Rewirable connectors shall be provided with clamping units according to IEC 60999-1.

– 4 – 60320-1 Amend. 1 © IEC:2007
Non-rewirable connectors shall be provided with soldered, welded, crimped or equally
effective screwless connections, which shall not allow the possibility to disconnect the
conductor. Screwed connections shall not be used.
The end of a stranded conductor shall not be consolidated by soft soldering at places where
the conductor is subject to contact pressure unless the clamping means is designed so as to
obviate the risk of a bad contact due to cold flow of the solder.
Replace the existing subtitle “Screw-type terminals” with the following new Subclause 12.3:
12.3 Rewirable connectors with a rated current not exceeding 16 A shall have a rated
connecting capacity of 1,5 mm according to IEC 60999-1.
Compliance is checked by the relevant tests of IEC 60999-1.
Delete all subclauses from 12.2.1 to 12.2.12.
Add the following new subclauses:
12.4 Clamping units shall be so fixed or located within the connector that when operated,
the clamping units shall not work loose and creepage distances and clearances shall not be
reduced below the values specified.
NOTE 1 These requirements do not imply the terminals should be so designed that their rotation or displacement
is prevented, but any movement should be sufficiently limited so as to prevent non-compliance with this standard.
NOTE 2 The use of sealing compound or resin is considered to be sufficient for preventing a terminal from working
loose, provided that
− the sealing compound or resin is not subject to stress during normal use, and
− the effectiveness of the sealing compound or resin is not impaired by temperatures attained by the terminal
under the most unfavourable conditions as specified in this standard.
Compliance is checked by the relevant tests of IEC 60999-1.
12.5 Clamping units for earthing conductors shall be of the same size as the corresponding
terminals for the current carrying conductors.
Compliance is checked by inspection.

15 Insulation resistance and electric strength
15.2
Replace, on Page 55, item f) by:
f) for rewirable connectors, between any metal part of the cord anchorage, excluding
+0
clamping screws, and a metal rod, of the maximum diameter of the cord mm,
−1
inserted in its place.
Replace the second and third paragraphs after Table 2 by the following text:

60320-1 Amend. 1 © IEC:2007 – 5 –
The term "body" used in items a) and c) above includes all accessible metal parts, fixing
screws, external assembly screws and the like and a metal foil in contact with the outer
surface of external parts of insulating material, in item c) including the engagement face of
connectors. The metal foil is wrapped round the outer surface of external parts of insulating
material; however, it is not pressed into openings.
15.3
Replace the second and third paragraphs by:
The value of the test voltage is 3 000 V ± 60 V when applied between the parts and the body
specified in items a) and c) and 1 500 V ± 60 V in all other cases. Initially, not more than half
the prescribed voltage is applied, and then it is raised rapidly to the full value.

16 Forces necessary to insert and to withdraw the connector
16.2 Verification of the maximum withdrawal force
Replace, in the first paragraph, “figure 11” by “Figure 12".
Page 61
18 Resistance to heating of appliance couplers for hot conditions or very hot
conditions
18.1
Replace the second paragraph by:
Connectors for hot and very hot conditions shall be so constructed that the body shall not
allow separation from the front during the tests and the insulation of the core of the cord shall
not be subjected to excessive heating.
18.2
Replace the paragraph “After removal from the apparatus … appliance inlet 10 times” by:
After removal from the test apparatus, one of the connectors shall be subjected to the test of
23.7 within 15 s. The connectors are then allowed to cool down to approximately ambient air
temperature and are inserted into and withdrawn from the appliance inlet 10 times.
Page 63
19 Breaking capacity
Replace the third paragraph by:
The connector is mounted in an appropriate test apparatus, which incorporates an appliance
inlet having polished, hardened steel pins, and dimensions as specified in the relevant

– 6 – 60320-1 Amend. 1 © IEC:2007
standard sheet. The ends of the pins shall be rounded for rectangular pins and hemispherical
for round pins as shown in the standard sheets.
Add the following new paragraph after the fourth paragraph:
The test apparatus shall be designed and adjusted so as to simulate as far as possible
disconnection in normal use.
Page 67
21 Temperature rise
Replace the third paragraph by the following:
Rewirable connectors are fitted with polyvinyl chloride insulated cords having a length of 1 m
2 2
and a cross-sectional area of 1 mm for 10 A connectors and 1,5 mm for 16 A connectors.
Screws of clamping units, if any, are tightened with the torque values specified in the
appropriate column of Table 8 of 25.1.
Non-rewirable connectors are tested with the cord as delivered.
22 Cords and their connection
22.1
Replace the third paragraph by the following:
Non-rewirable connectors shall be provided with a type of cord complying with the standard
indicated in Table 4 for the type of connector and, in addition, the cord shall have a cross-
sectional area not less than that specified in Table 4.
22.3
Replace, on Page 71, the paragraph after Table 5 by the following:
Conductors of the cord of rewirable connectors are introduced into the clamping units, and the
screws of clamping units, if any, are tightened just sufficiently to prevent the conductors from
easily changing their position.
Replace the third paragraph before the Note by the following:
After the tests, the cord shall not have been displaced by more than 2 mm. For rewirable
connectors, the ends of the conductors shall not have moved noticeably in the terminals; for
non-rewirable connectors, there shall be no break in the electrical connections. A visual
inspection is made to ensure no undue twisting of the conductors where they are connected to
