2 Safety and the environment
7
Testo measuring instruments (as of July 2020) can be used in
compliance with the prescribed laws, standards, directives and
safety regulations for refrigeration systems and refrigerants as
well as regulations of the manufacturers of refrigerants of safety
group A2L as per ISO 817.
Regional standardization and interpretation must always be
observed.
For example, DIN EN 378-Part 1-4 applies to the scope of the
EN standards.
During maintenance work, the employer must ensure that a
hazardous explosive atmosphere is prevented (see also
TRBS1112, TRBS2152 VDMA 24020-3).
A hazardous and potentially explosive atmosphere must be
anticipated during maintenance and repair work on refrigeration
systems with flammable refrigerants (e.g. those of category A2L
and A3).
Maintenance, repairs, removal of refrigerants and
commissioning of systems may only be carried out by qualified
personnel.
