Mandatory traceability
1.
Based on legislative requirements, all operators in the logistics chain, from the manufacturer of the certified Ex solenoid coil to the end user
of the complete equipement, are obliged to make and maintain traceability records of Ex products, enabling, if necessary, the withdrawal
of products of certain serial numbers from the market due to defects of non-conformities, endangering safety of use in an explosive
atmosphere. In practice, this means keeping records of the assignment of Ex coil/valve identification numbers to the identification numbers
of the operators immediately down the logistics chain.
2.
To meet the requirement for traceability of Ex products, it is necessary to keep product type labels legible throughout their technical life.
