Add the following paragraph to the addition Unless the motor-compressor complies with IEC 60335-2-34, at least one additional specially prepared sample is required for the tests of 22.103 Delete the second paragraph of the addition In the existing third paragraph of the addition replace “Other appliances” by “Appliances, other than built-in appliances , ” Add the following as a new third paragraph to the addition For appliances incorporating remote refrigerant units or remote motor-compressors, the refrigerant line between the refrigerant unit or motor-compressor and the refrigerated display and storage cabinet shall have a length of m to 7, 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 prefitted to the motor-compressor M arki ngs and i nstructi ons In the paragraph after Note 101, replace “the symbol “Caution: risk of fire” with “symbol In the note, replace “the sym bol “Caution: risk of fire” with

the following sentence to the end of the second paragraph of the requirement “This requirement is not applicable where the pressure is controlled automaticall y by shutting down the motor-com pressor.” 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 22.1 04 Replace the text by the following: Accessible glass panels with an area having an y two orthogonal dimensions exceeding 75 mm shall be m ade from • • glass that breaks into sm all pieces when it fractures; or glass that is not released or dropped from its norm al 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 Th e edg es of th e sam ple to be tested are contai ned with in a fram e of adhesi ve tape in such a m anner th at the broken pi eces rem ain in place after breakag e but with out hind eri ng expansi on of the sam ple The sample under test is broken by means of a test punch having a head with a mass of 75 g ± 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 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 I n the case of curved glass, plan e pieces of the sam e m aterial 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 ± 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 I EC 60335-2-89: 201 0/AMD2: 201 © I EC 201 –5– 22.1 09 In the requirement, replace “ignition” by “auto-ignition” Replace Table 102 by the following: Table 02 – Refrigerant

following to the end of the subclause: Replaceable bursting discs in bursting disc assemblies need only be marked with their operating pressure Add the following new subclause: 24.7 Modification: For coupling nuts used with hose-sets marked 25 °C max, the 96 h ageing test is carried out at a temperature of 32 °C ± °C on hoses sets supplied with appliances of climatic class 0, 1, 2, 3, 4, or 8; • 43 °C ± °C on hoses sets supplied with appliances of climatic class or 24.1 01 Replace the requirement by the following • Pressure relief devices shall be such that they are able to operate so that
