25、ction This document is a type-C standard as stated in ISO 12100. The machinery concerned and the extent to which hazards, hazardous situations or hazardous events are covered are indicated in the Scope of this document. When requirements of this type-C standard are different from those which are sta
26、ted in type-A or -B standards, the requirements of this type-C standard take precedence over the requirements of the other standards for machines that have been designed and built according to the requirements of this type-C standard. EN ISO 8230-2:2008 (E) DIN EN ISO 8230-2:2009-05 41 Scope This pa
27、rt of ISO 8230 specifies safety requirements for dry-cleaning machines that exclusively use perchloroethylene (hereinafter known as “perc”) as their cleaning medium. It is applicable to such dry-cleaning machines, within the scope of ISO 8230-1, when they are used as intended and under conditions of
28、 misuse that are reasonably foreseeable by the manufacturer. It is not applicable to: open-circuit dry-cleaning machines; transfer machines. NOTE See ISO 8230-1 for the definitions of those machines. This part of ISO 8230, in conjunction with ISO 8230-1, deals with all significant hazards, significa
29、nt hazardous situations and significant hazardous events that have been identified as being significant to the types of machines covered by this part of ISO 8230 and which require specific action by the designer or manufacturer to eliminate or reduce the risk. It deals with the following significant
30、 hazards specific to the use of perc, which can lead to the inhalation of unhealthy vapours, to perc contact with the skin (including of the feet) or eyes of the machine operator and those of other personnel and members of the public, as well as to water and ground contamination: a) perc emission to
31、 the workroom, seepage into the ground and sewer during operation and maintenance of the water separator; b) perc emission resulting from operation, cleaning and maintenance of the distilling installation. This part of ISO 8230 applies to machines manufactured after the date of its issue. 2 Normativ

35、nd/or protective measures of ISO 8230-1, in as far as these are not modified or completed by this clause and other requirements of this part of ISO 8230. 4.2 Hazards generated by perc 4.2.1 Ventilation The dry-cleaning machine shall have a provision for allowing the interlocking of its functioning w
36、ith the general room ventilation. Appropriate advice shall be given in the instruction handbook. 4.2.2 Perc emission to the workroom, and seepage into ground and sewer during operation and maintenance of water separator The water outlet of the separator shall lead through a pipe into a sealed collec
37、ting system e.g. into an additional decantation tank or a purifying system in order to avoid the loss of perc. It shall be possible to detect the presence of perc in the tank, e.g. by means of a sight glass. The capacity of the water-collecting tank shall be not less than the maximum one-days produc
38、tion for which the dry-cleaning machine is intended. A label on the collecting tank shall indicate that the water contains perc. The wording of this label shall be reproduced in the instruction handbook. The instruction handbook shall include information about the measures for preventing perc spills
39、 during maintenance operations on the water separator and sealed collecting system. Drainage from a water separator and any associated collecting system shall be possible either via a manual valve that closes automatically when released or via a direct return circuit to the still or other reservoir.
40、 NOTE National regulations may require specific contact water disposal. 4.2.3 Perc emission resulting from operation, cleaning and maintenance of distilling installation 4.2.3.1 A still pressure-relief device shall be fitted, capable of releasing excess pressure by evacuating the volume of gas gener
41、ated by distillation at maximum rate. The pressure-relief device shall be accessible for enabling inspection. Operation of the pressure-relief device shall cut off the heating of the still. The instruction handbook shall describe the inspection procedure for the pressure-relief device. The instructi
42、ons for installation shall advise on how to evacuate the exhaust without polluting the workroom, e.g. to the outside. 4.2.3.2 The temperature of the still heating surface shall not exceed 150 C. 4.2.3.3 If manual valves are provided for air or steam injection into the still, these shall return to th
43、e closed position when released. 4.2.3.4 The coolant flow shall be interlocked with the heating of the still in such a way as to stop heating when the coolant flow is reduced below a safe limit and to produce a visual or acoustical alarm. This can be EN ISO 8230-2:2008 (E) DIN EN ISO 8230-2:2009-05
44、6achieved, e.g. by a pressure sensor in the coolant service or a sensor of the solvent condensate temperature. This temperature shall not exceed 55 C. 4.2.3.5 If a manual drain valve is installed to empty the still in the event of breakdown or to reduce the oily residues prior to opening the cleanin
45、g door, it shall have an interlocking provision with locking so that it can only be opened if the temperature is below 40 C and it shall return automatically to the closed position when released. 5 Verification of the safety requirements and/or protective measures Verification of the safety requirem
46、ents and/or protective measures, as well as requirements of Clause 6, shall be in accordance with ISO 8230-1 and Table 1.
