Here you can read incoming questions and answers in connection with the free webinar on Ex marking.
Considering sensors and permanent marking (not stickers), do these have to have a metal sign? From when does this requirement apply and is this a specifically Norwegian requirement?
It doesn't say anything that it has to be metal tags, but they mention that "self-adhesive tags" are an example of "non-permanent" marking. They open up the possibility that such labeling can describe limitations in the instructions for use, such as, for example, the location of the product.
Excerpt from the article:
"The market participants are obliged to ensure that ATEX products that are made available on the market are provided with easily legible and permanent marking adapted to the intended use. Any restrictions on use must be described in the instructions for use, cf. FUSEX § 5, cf. appendix II, point 1.0.6. This also includes any restrictions on the placement of the product".
Will a trafolyte or stainless nameplate attached with tape or glue be permanently marked, or must it be mechanically attached by welding or screw/bolt?
They say nothing about that, but it is important that the attachment of the nameplate does not impair the protection method, by, for example, drilling holes or using glue on plastic which can affect impact resistance.
Manufacturers abroad will not comply with such special Norwegian requirements for metal signs, i.e. you can't use the majority of all instrumentation?
IEC 60079-14:2013 requires that whoever chooses Ex equipment must choose equipment that is adapted to the external influences the equipment can currently be exposed to. 5.9. In the letter from DSB/Ptil/Arbeidstilsynet, they demand that suppliers state any restrictions in the instructions for use, also regarding the nameplate.
