Note: The test is based on ratified valid standards in 2017.
Scope of application:
Emerson EXM/L expansion valves are intended to be used built in a finished product or integrated in a refrigeration system, and electrically
controlled by a DC supply separate control. The valve is designed for a built-in situation, and the controller was not included in the testing in
order to be applicable with any controller.
1.
Fundamental
requirements:
•
The valve shall not be user-accessible, it must be inside of a system which only should be handled by refrigeration engineering experienced
persons.
•
Protection against:
electric shock,
contact with live parts,
ingress of water or solid foreign objects.
2.
Following subjects
have to be checked
in final built
position
.
•
Appliances having adequate stability.
•
Accessible parts with solid insulation having strength to prevent penetration by sharp implements.
•
Refrigeration system shall withstand a pressure of 3.5 times the saturated vapor pressure of refrigerant at 70°C, or equal to 3.5 times the
pressure at the critical temperature if this is lower than 70°C, the test pressure being rounded up to the next 5 bar.
•
Electrical connections are not subject to pulling during cleaning of compartments to which access can be gained without the aid of a tool,
and that likely to be cleaned in normal use.
•
Insulation and internal wiring, are not exposed to oil, grease or similar substances.
•
For class III constructions the insulation between parts operating at safety extra-low voltage and other live parts must comply with the
requirements of double or reinforced insulation.
•
Conductive liquids that are or may become accessible in normal use and conductive liquids that are in contact with unearthed accessible
metal parts shall not be in direct contact with live parts or unearthed metal parts that are separated from live parts by basic insulation only
.
•
Wireways are smooth and free from sharp edges.
•
Electrical connections and internal conductors moveable relatively to each other are not exposed to undue stress.
•
Sleeving as supplementary insulation retained in position by clamping at both ends.
•
For appliances that are operated while attended, parts of non-metallic material supporting current-carrying connections and parts of non-
metallic material within a distance of 3 mm of such connections are subjected to the glow-wire test of IEC 60695-2-11.
