Safety requirements for electrical equipment for measurement, control and laboratory use - Part 2-012: Particular requirements for climatic and environmental testing and other temperature conditioning equipment

1 Scope and object
This clause of Part 1 is applicable except as follows:
1.1.1 Equipment included in scope
Replacement:
Replace the first paragraph by the following:
This group safety publication is primarily intended to be used as a product safety standard for
the products mentioned in the scope, but shall also be used by technical committees in the
preparation of their publications for products similar to those mentioned in the scope of this
standard, in accordance with the principles laid down in IEC Guide 104 and lSO/lEC Guide 51.
This Part 2 of IEC 61010 specifies safety requirements for electrical equipment and their
accessories within the categories a) through c), wherever they are intended to be used,
whenever that equipment incorporates one or more of the following characteristics:
– A REFRIGERATING SYSTEM that is acted on or impacted by an integral heating function such
that the combined heating and cooling system generates additional and/or more severe
HAZARDS than those for the two systems if treated separately.
– The materials being treated in the intended application introduce significant heat into the
REFRIGERATING SYSTEM that the cooling system in the application yield additional and/or
more severe HAZARDS than those for the cooling system if operated at the maximum RATED
ambient alone.
– An irradiation function for the materials being treated presenting additional HAZARDS.
– A function to expose the materials being treated to excessive humidity, carbon dioxide,
salt mist, or other substances which may result in additional HAZARDS.
– A function of MECHANICAL MOVEMENT presenting additional HAZARDS.
– Provision for an OPERATOR to walk-in to the operating area to load or unload the materials
being treated.

Varnostne zahteve za električno opremo za meritve, nadzor in laboratorijsko uporabo - 2-012. del: Posebne zahteve za opremo za klimatska in okoljska preskušanja ter drugo opremo za uravnavanje temperature - Dopolnilo A11

Ta del standarda IEC 61010 določa varnostne zahteve za električno opremo in njene dodatke v kategorijah od a) do c), kjer koli je namenjena za uporabo in ima eno ali več spodaj navedenih lastnosti:
– HLADILNI SISTEM, ki ga upravlja ali nanj vpliva vgrajena grelna funkcija tako, da skupni grelni in HLADILNI SISTEM ustvarjata dodatne in/ali večje NEVARNOSTI, kot če bi bila sistema neodvisna;
– materiale, ki se obdelujejo pri namenski uporabi, vpeljejo znatno količino toplote v HLADILNI SISTEM, tako da HLADILNI SISTEM pri taki uporabi ustvarja dodatne in/ali večje NEVARNOSTI, kot če bi deloval zgolj pri največji NAZIVNI temperaturi okolja;
– funkcijo obsevanja obdelovanih materialov, ki predstavlja dodatne NEVARNOSTI;
– funkcijo za izpostavljanje materialov, ki se obdelujejo, prekomerni vlagi, ogljikovemu dioksidu, solni megli ali drugim snovem, ki lahko povzročijo dodatne NEVARNOSTI;
– funkcijo MEHANSKEGA GIBANJA, ki predstavlja dodatne NEVARNOSTI;
– določbo, ki UPRAVLJAVCU dovoljuje, da vstopi na območje delovanja, da naloži ali razloži obdelovane materiale.

Safety requirements for components and piping
The sealed system components can be considered pressure vessels as stated in the Pressure
Equipment Directive (PED) 2014/68/EU according to the classification in Table CC.1 and Table CC.2. If
the components or piping are classified as a Category II or a higher pressure vessel as stated in the
PED, then the requirements of Table CC.3 shall apply including the use of a Notified Body to the PED.

3 Modification to 6.8.3.1, “The a.c. voltage test”
Replace the first sentence by the following sentence:
“The voltage tester shall be capable of maintaining the test voltage throughout the test within ± 5 % of
the specified value.”
4 Modifications to Clause 11, “Protection against HAZARDS from fluids and
solid foreign objects”
In 11.1, “General”, delete the added text after the first conformity statement.
Add the following subclause:
“11.101 Protection of hot and cold water services
Back-siphonage from the equipment to the potable water services shall be prevented by means
meeting the relevant requirements of EN 61770. Attention is drawn to the existence of national and
local regulations. If the means are to be provided by the RESPONSIBLE BODY, this shall be stated in the
manufacturer’s installation instructions.
Conformity is checked by inspection and by examination of the manufacturer’s instructions.”
5 Modification to Annex CC, “Safety requirements for components and
piping”
Replace Annex CC by the following text:
"Annex CC
(normative)

Safety requirements for components and piping
The sealed system components can be considered pressure vessels as stated in the Pressure
Equipment Directive (PED) 2014/68/EU according to the classification in Table CC.1 and Table CC.2.
If the components or piping are classified as a Category II or a higher pressure vessel as stated in the
PED, then the requirements of Table CC.3 shall apply including the use of a Notified Body to the PED.
