1 Modification to Clause 2, “Normative references”
Add the following references:
IEC 60364-5-53:2019, Low-voltage electrical installations -- Part 5-53: Selection and erection of electrical
equipment - Protection, isolation, switching, control and monitoring
ISO 4892-1:2016, Plastics — Methods of exposure to laboratory light sources — Part 1: General guidance
ISO 4892-2:2013, Plastics - Methods of exposure to laboratory light sources - Part 2: Xenon-arc lamps -
Amendment 1: Classification of daylight filters
ISO 4628-3:2016, Paints and varnishes — Evaluation of degradation of coatings — Designation of quantity and
size of defects, and of intensity of uniform changes in appearance — Part 3: Assessment of degree of rusting
2 Addition of subclause 8.8, “Additional information if declared by the
manufacturer - Vibration and shock”
Add the following new subclause 8.8 after 8.7:
“8.7 Additional information if declared by the manufacturer - Vibration and shock
Information on vibration and shock tests for transportation and special applications can be found in Annex ZB.”
3 Modification to Table 16, “Cross-sections of copper conductors for screw-type or
screwless terminals”
Delete the column “American Wire Gauge”.
4 Modification to A.1, “Routine tests”
Replace the whole paragraph with the following:
“Appropriate test(s) shall be performed during manufacturing production to verify that the SPD is capable of
meeting its performance.”
5 Modification to G.2.2, “Preconditioning procedure”
Replace the Note with the following:
“
NOTE After the preconditioning, the modification of the samples is done by the manufacturer under supervision of the
test laboratory to avoid any unintended damage to the test samples.”
6 Addition of Annex ZB, “Vibration and shock test”
Add the following annex:
“
As impacted by IEC 60364-5-53:2019/AMD1:2020.
As impacted by ISO 4892-2:2013/AMD1:2021.
Annex ZB
(informative)
Vibration and shock test
ZB.1 Introduction
This annex gives information if the manufacturer declares performances for vibration and shock conditions.
ZB.2 Vibration and shock test
Vibration and shock tests shall be performed according to
— EN 60068-2-6 for sinusoidal Vibration test,
— EN 60068-2-64 for broadband random Vibration test, and
— EN 60068-2-27 for shock test.
Usually SPD are subject to mechanical stress due to transportation. This should be checked by a vibration and
shock test with the parameters given in EN 60721-3-2.
Special application of SPDs may require additional vibration and shock tests.
The typical values can be as shown in Table ZB.1.
