refrigerant line between the refrigerant unit or motor-compressor and the refrigerated
display and storage cabinet shall have a length of 5 m to 7,5 m. The refrigerant line shall be
installed with thermal insulation applied in accordance with the instructions. If the appliance
employs a transcritical refrigeration system, a pressure relief device shall be installed on
the high pressure side between the motor-compressor and the gas cooler unless it is pre-
fitted to the motor-compressor.

“This requirement is not applicable where the pressure is controlled automatically by shutting
down the motor-compressor.”
In the second paragraph of the test specification replace “raised gradually” by “gradually
increased hydraulically” and change the style of the first dashed item to italic type.
22.104 Replace the text by the following:
Accessible glass panels with an area having any two orthogonal dimensions exceeding
75 mm shall be made from
• glass that breaks into small pieces when it fractures; or
• glass that is not released or dropped from its normal position when broken.
a) For glass that breaks into small pieces when it fractures, compliance is checked by the
following test which is performed on two samples.
Frames or other parts attached to the glass panel to be tested are removed and the glass
is placed on a rigid horizontal flat surface.
NOTE 1 The edges of the sample to be tested are contained within a frame of adhesive tape in such a
manner that the broken pieces remain in place after breakage but without hindering expansion of the sample.
The sample under test is broken by means of a test punch having a head with a mass of
75 g ± 5 g and a conical tungsten carbide tip with an angle of 60°± 2°. The punch shall be
positioned approximately 13 mm in from the longest edge of the glass at the midpoint of
that edge. The punch is then hit by a hammer so that the glass breaks.
A transparent mask of 50 mm × 50 mm is placed on the fractured glass except within a
peripheral margin of 25 mm from the edge of the sample.
The assessment shall be undertaken on at least two areas of the sample, and the areas
chosen shall contain the largest particles.
The number of crack free particles within the mask are counted and for each assessment
shall not be less than 40. The particle count shall be made within 5 minutes of the
fracture. Each particle wholly contained within the area of the mask shall be counted as
one particle and each particle that is partially within the mask shall be counted as a half
particle.
NOTE 2 In the case of curved glass, plane pieces of the same material can be used for the test.
b) For glass that is not released or dropped from its normal position when broken,
compliance is checked by braking the glass when mounted in its normal position in the
appliance by means of a test punch having a head with a mass of 75 g ± 5 g and a conical
tungsten carbide tip with an angle of 60°± 2°. The punch shall be positioned approximately
13 mm in from the longest edge of the glass at the midpoint of that edge. The punch is
then hit by a hammer so that the glass breaks.
At the conclusion of this test, the glass shall not be broken or cracked in such a way that
pieces are released or dropped from their normal position. Glass that is released within
the immediate vicinity of the punch tip as a result of the punch impacting the sample under
test is ignored.

22.109 In the requirement, replace “ignition” by “auto-ignition”.
