The work of preparing International Standards is normally carried out through ISO technical commi

24、ttees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the I

25、nternational Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft Internationa

26、l Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the

27、 subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 8230-2 was prepared by Technical Committee ISO/TC 72, Textile machinery and accessories, Subcommittee SC 5, Industrial laundry and dry-cleaning machinery and accessories. This first editio

28、n of ISO 8230-2, together with ISO 8230-1:2008 and ISO 8230-3:2008, cancels and replaces ISO 8230:1997, of which it constitutes a technical revision.

The machinery concerned and the extent to which hazards, hazardous situati

30、ons 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 stated in type-A or -B standards, the requirements of this type-C standard take precedence over the requirements of the other standards for ma

32、 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 misuse t

33、hat 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, significant hazard

34、ous 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 hazards

35、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 the work

36、room, 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 Normative referen

37、ces The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. ISO 8230-1:2008, Safety requirements for dry-

39、 8230-2:2008(E) 2 ISO 2008 All rights reserved3 Terms and definitions For the purposes of this document, the terms and definitions given in ISO 12100-1 and ISO 8230-1 apply. 4 Safety requirements and/or protective measures 4.1 General Dry-cleaning machines using perc shall comply with the safety req

40、uirements and/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 fu

41、nctioning with 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 se

42、aled collecting 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-

43、days production 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

44、perc spills 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

45、 reservoir. 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 o

46、f gas generated 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. Th

47、e instructions 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 r

48、eturn to the 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 BS EN ISO 8230-2:2008ISO 8230-2:2008(E

49、) ISO 2008 All rights reserved 3achieved, 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 cleaning 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.
