7 Protection against mechanical HAZARDS
7.1 General
Replacement:
Replace the NOTE with the following:

NOTE If the equipment consists of two or more units, the value of the mass refers to the mass of each individual

unit. However, if one or more units are intended to be attached to and supported by another unit, these units are

treated as a single unit.
7.3.3 RISK assessment for mechanical HAZARDS to body parts
Table 12 – Protective measures against mechanical HAZARDS to body parts
Replacement:

Replace, in footnote “ Minimum protective measures:” the text of B with the following:

B = Moderate measures; emergency switches, PROTECTIVE BARRIERS or covers removable only

with a TOOL, distances (see ISO 13857), or separations (see ISO 13854 or EN 349).

7.3.4 Limitations of force and pressure
Deletion:
Delete the second sentence of the third paragraph.
Addition:
Add the following at the end of the conformity statement:

For the purposes of this subclause, the width of a finger is considered to be 1,2 cm and the

width of any other body part is considered to be 5,0 cm. The contact area will be determined

to be the width of the body part multiplied by the width of the moving part, or the cross-

sectional contact area of the moving part, if smaller.

EXAMPLE In a particular case, a finger might be able to touch a moving part that is 0,9 mm wide. If the part can

exert a continuous force of 40 N, then the contact pressure would be calculated as:

Area = 1,2 cm × 0,09 cm = 0,108 cm
2 2
Pressure = 40 N / 0,108 cm = 370 N/cm

In this case, the pressure exceeds the permissible limit even though the force is less than the permissible limit. In

this case, the moving part would be considered to be hazardous.
7.4 Stability
Replacement:
Replace the third paragraph with the following:

Each castor and support foot shall be RATED to support a load not less than its normal load, or

the castors and support feet shall be tested according to d) or e) below.
Deletion:
Delete NOTE 2 and renumber NOTE 1 as “NOTE”.

Conformity is checked by inspection and measurement and for solid insulation by the a.c.

voltage test of 6.8.3.1 or the d.c. voltage test of 6.8.3.2 (without humidity preconditioning)

using the test voltage from Table 5 for BASIC INSULATION for the appropriate line-to-neutral

voltage for 1 min. EMC capacitors meeting the requirements of Clause 14 may be
disconnected during the voltage test.
10 Equipment temperature limits and resistance to heat
10.1 Surface temperature limits for protection against burns
Replacement:
Replace, in the NOTE in Table 19, "EN 563" with "ISO 13732-1".
10.4.1 General
Addition:
Add, after the second paragraph, the following:
Alternatively, temperature measurements are made at the least favourable ambient

temperature within the RATED ambient temperature range of the equipment if this represents a

less favourable condition. Measures are taken to eliminate errors caused by the method of

achieving the test ambient temperature (e.g. suitable baffling or enclosure if the test is

conducted in an environmental chamber and the forced air movements would cool the exterior

of the equipment).

11.6 Equipment RATED with a degree of ingress protection (IP code)
11.6.1 General

Equipment RATED by the manufacturer as conforming to one of the degrees of protection as

defined in IEC 60529 shall adequately resist the ingress of solid foreign objects and water

which could lead to a HAZARD.
Equipment may have different degrees of protection depending on the mounting

arrangements, or the assembly or operating conditions. The degrees of protection shall be

specified in the documentation for each mounting arrangement. If the degree of protection

depends on particular positions, covers, seals, or operating conditions, these conditions shall

be specified in the documentation.

If the RATING is marked on the equipment, it shall be marked on the equipment in a manner to

avoid misunderstanding and misuse. The designations of IEC 60529 shall be used (IP code).

The IP code and related operating or non-operating conditions shall be explained in the

documentation together with other warnings.

For IPx8 testing, the water level above the equipment and the test duration shall be applied

as specified in the documentation. The aforementioned conditions shall be more severe than

those for IPx7 according to IEC 60529.

Conformity is checked by inspection and as specified in 11.6.2 to 11.6.4 as applicable.

11.6.2 Conditions for testing

The equipment shall be in a clean and new condition with all parts in place and mounted in

the manner defined by the manufacturer. If it is impracticable to test the complete equipment,

representative parts or smaller equipment having the same full-scale design details shall be

tested.

HAND-HELD EQUIPMENT is placed in the least favourable position. Portable equipment is placed

in the least favourable position of normal use. Other equipment is positioned or installed as

specified in the installation instructions.

TERMINALS are considered to be part of the equipment. However, TERMINALS provided with a

protective cap or cover necessary to maintain the rated degree of protection are installed as

specified by the manufacturer.
The equipment is operating (energized) during the treatment except

a) if the manufacturer specifies degrees of protection for non-operating (de-energized)

equipment, or

b) if, whether the equipment is operating or not operating during the treatment does not

affect the test results.

EXAMPLE 1 A field housing contains electronics. Generally in this case it has no influence on the test results

whether the electronics inside is operated or not. So the testing of the equipment can also be conducted without

the electronics built in.

EXAMPLE 2 An equipment enclosure has a rotating shaft protruding from it using an appropriate seal for the

relevant ingress pr
