8 Marking and documentation

8.8 Replace all existing paragraphs with the following new paragraphs, and add new

Figure 8:

The marking according to 8.2, 8.3 and 8.4 shall not be placed on easily removable parts such

as screws or washers.

Laser marking directly on the product and marking made by moulding, pressing or engraving

are not subjected to this test.
---------------------- Page: 6 ----------------------
IEC 61534-1:2011/AMD2:2020 – 5 –

Compliance is checked by the tests in 8.9 and 8.10 and by inspection, using normal or corrected

vision, without additional magnification and by rubbing the label using the equipment shown in

Figure 8. New samples shall be used for 8.9 and 8.10.
Key
A Diameter of the piston (20 ± 1) mm
B Radius of the piston head (20 ± 1) mm
C Gap between piston head and cylinder (2 + 1/− 0) mm
Figure 8 – Piston for durability of marking test

The test piston head shall be made of an elastic material which is inert against the test liquids

and has a Shore-A hardness of 47 ± 5 (for example synthetic rubber). The piston shall be

wrapped with cotton comprising cotton wool covered by a piece of cotton medical gauze.

When it is not possible to carry out the test on the specimens due to the shape/size of the

product, a suitable piece of the product having the same characteristics can be submitted to

the test.

The test shall be carried out on one sample. If the sample does not satisfy the test, the test

shall be repeated on two new samples, both of which shall comply with the requirements.

Add the following two new subclauses:
8.9 Durability of marking

The sample shall be rubbed by applying a compression force of (5 ± 1) N at a rate of one cycle

per second for 15 s (a cycle comprising a forward and backward movement along the length of

the marking) by means of the test piston shown in Figure 8.

Rubbing shall commence immediately after soaking the piece of cotton with water. For markings

longer than 20 mm, rubbing can be limited to a part of the marking, over a path of at least

20 mm length.

The sample surface shall then be dried, and the test repeated on the same sample using new

cotton soaked in n-hexane 95 % solvent.

When using this liquid, precautions as stated in the relevant material safety datasheet provided

by the chemical supplier shall be taken to safeguard the person performing the test.

NOTE n-hexane 95 % (Chemical Abstracts Service Registry Number, CAS RN, 110-54-3) is available from a variety

of chemical suppliers as a high pressure liquid chromatography (HPLC) solvent.
After the test, the marking shall be legible.

Under consideration.
9 Construction
Add the following new subclause:
9.9 Requirements for PT system with more than one circuit

When a PT system with tap-off facilities is intended to supply several circuits in the same

powertrack, the system shall be designed and constructed to prevent tap-off units from being

connected to the wrong circuit.
Compliance is checked by inspection.
20 Fire hazard
20.2 Flame spread
Replace the third paragraph with the following new paragraph:

The test is made on a single straight length of powertrack as supplied by the manufacturer

together with at least one tap-off outlet and any associated covers. The overall length of the

sample shall be (675 ± 10) mm.
Replace the seventh paragraph with the following new paragraph:

The flame shall be applied to the front face of the tap-off outlet as shown in Figure 3. The

sample is exposed to the flame for (60 ± 2) s.

Figure 3: Replace existing Figure 3 and its Key with the following new Figure 3 and Key and

move the new Figure 3 and Key to the end of this Subclause 20.2 as follows:

All grease shall be removed from the sample to be tested by cleaning with n-hexane 95 %

(Chemical Abstracts Service Registry Number, CAS RN, 110-54-3), after which all parts shall

be dried.

When using the liquid specified for the test, precautions as stated in the relevant material safety

datasheet provided by the chemical supplier shall be taken to safeguard the person performing

the test.

Replace the existing third paragraph, i.e. the paragraph directly preceding the note, with the

following new paragraphs:

Without drying, but after shaking off any drops, the parts shall then be immediately placed for

min in a box containing air saturated with moisture at a temperature of (20 ± 5) °C. The

( −0)

parts shall then be dried for 10 min in a heating cabinet at a temperature of (100 ± 5) °C. After

removal from the heating cabinet, any traces of rust and/or yellowish film may be removed by

rubbing the appropriate area for s with an applied force of N, using a cotton cloth

( −0)
( −0)
lightly moistened with methylated spirit.

Compliance is checked by visual inspection to determine that there is no evidence of iron oxide,

cracking or other deterioration more than that allowed by ISO 4628-3 for a degree of rusting
