FAQ
Directive SNG 482638 issued on 03/01/2023 replaces SNR 462638 issued on June 28, 2018. The new directive clarifies some aspects of SNR.
The employer is responsible. It will be the employer who defines the intervals of periodic inspections based on the manufacturer's instructions or a risk assessment.
No, periodic inspection of appliances in private homes is the responsibility of the user.
Yes, if during the period of use the equipment is transferred to a third party, and if during use this equipment undergoes safety-relevant alterations, a periodic inspection or post-repair inspection must be carried out before each transfer.
If an electrical appliance is modified and safety is significantly compromised, the provisions for placing a new product on the market must be followed. (NEV art.21§3)
No, stationary equipment must also be checked. Stationary machines do not have to be checked. (Difference between apparatus and machinery see EN 60335-1)
Absolutely recommended. The standard does not require it, but in case the test fails, it becomes easier to have the support of the manufacturer/reseller. In addition, you can keep track of a note, on any specifications that may be forgotten over time.
No, these do not need to be checked. These are part of the infrastructure (SN 411000).
It's always good to test equipment as it would be used.
None, the first is valid in Germany and the second has jurisdiction on Swiss territory.
Generally speaking, no. Computer and multimedia equipment are generally not dangerous, and should be checked every 5 years, generally a longer period than their lifespan. Safety is defined as "Freedom from unacceptable risk" (ISO 14971, cpv.2.24). The same applies to the packaged cables used to power them.
new Note: for equipment that is not exposed to mechanical stress or harmful effects, periodic inspections from the SNG directive can usually be avoided by following the manufacturer's data.
Equipment should never be disassembled for measurement. If the ground connection cannot be reached, that measurement will not be made.
These are to be done with the lab manager.
These devices are normally Class 1. They should be labeled and can continue to be used after they pass inspection.
Unplug the appliance from the mains, remove it from further use and if it cannot be repaired it must be disposed of.
And’ mandatory for public and professional entities. But as long as there are no accidents, there are no consequences....
Normally, no! With few exceptions, devices with foreign plugs should not be sold in Switzerland. Replace the foreign plug or use a permanent adapter to comply with SNG 482638.
Note: For appliances with a foreign plug, the professional replacement with a suitable Swiss plug does not affect conformity or warranty. (SNG 491000-3060 - SNG491000-3060_Jan2021_en_Brochure.pdf)
In keeping with OPBT Article 22b, measurements are not required, although SNG 482638 requires that this choice be documented.
In addition to the documentation referring to SNG 482638, the following should be available for each machine: (CFSL Directive 6512, para 4)
- manuals (operation, use and maintenance manuals). They must be written in Italian, French or German, as required by the company.
- declaration of conformity (only if purchased after 1st bJanuary 1997)
- declaration of incorporation (for incomplete machines)
For machines built by the company itself, the employer must ensure that they comply with the provisions of Omacch. He must meet the essential health and safety requirements of Annex 1 of the Machinery Directive, certify it with a declaration of conformity and provide the technical documentation and risk assessment (art.2 chapter 1b and 2 Omacch - CFSL 6512 art.4)
