ISO 8230-1:2008(E) iv © ISO 2008 – All rights reserved Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. 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 International 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 International 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 subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 8230-1 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 edition of ISO 8230-1, together with ISO 8230-2:2008 and ISO 8230-3:2008, cancels and replaces ISO 8230:1997, of which it constitutes a technical revision. ISO 8230 consists of the following parts, under the general title Safety requirements for dry-cleaning machines: ⎯ Part 1: Common safety requirements ⎯ Part 2: Machines using perchloroethylene ⎯ Part 3: Machines using combustible solvents SIST EN ISO 8230-1:2009

ISO 8230-1:2008(E) © ISO 2008 – All rights reserved vIntroduction 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 stated 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.
INTERNATIONAL STANDARD ISO 8230-1:2008(E) © ISO 2008 – All rights reserved 1Safety requirements for dry-cleaning machines — Part 1: Common safety requirements 1 Scope This part of ISO 8230 specifies common safety requirements for dry-cleaning machines. It is applicable to dry-cleaning machines of all sizes intended for industrial and commercial use for the cleaning of articles made of textile, leather, furs and skins, using exclusively either perchloroethylene or combustible solvent as the cleaning medium. It is not applicable to: ⎯ machines placed at the disposal of the general public (self-service); ⎯ barrier machines as defined in 3.1.5; ⎯ transfer machines as defined in 3.1.4; ⎯ ironing presses (see ISO 10472-1 and ISO 10472-6); ⎯ ancillary equipment, e.g. room ventilation equipment, waste recuperation systems of the still, external water cooling systems or external systems for solvent recovery from the still sludge. This part of ISO 8230 deals with all significant hazards arising from the use of the dry-cleaning machine, where “use of the dry-cleaning machine” comprises both intended use and foreseeable abnormal situations and includes commissioning, use and maintenance. It defines the common safety requirements for dry-cleaning machines and is intended to be used in conjunction with ISO 8230-2 and ISO 8230-3, as relevant. Specific requirements in those other parts of ISO 8230 take precedence over the respective requirements of this part of ISO 8230. It does not deal with hazards caused by processing items that can create an explosive atmosphere (e.g. printers' wipers containing a low-flash solvent), nor with machines processing loads that can contain “foreign solvents”, which could lead to a change in a property (characteristic) of the cleaning solvent, e.g. cause foaming or make it carcinogenic. This part of ISO 8230 applies to machines manufactured after the date of its issue. 2 Normative references The following referenced documents are indispensable for the application of this document.

ISO 8230-1:2008(E) © ISO 2008 – All rights reserved 94.2.3 Systems using thermal fluid at atmospheric pressure In order to avoid an excessive fluid temperature, this shall be controlled by a thermostatic heating regulator acting directly on the power control of the heater, completed by a second thermostat protected against manipulation or accidental change of the settings. The maximum limit of the adjustment range of the thermostats shall ensure that the operating temperature of the thermal fluid remains below the maximum temperature recommended by the thermal fluid manufacturer.
The temperature of the thermal fluid shall be sensed independently so as to monitor the correct running of the thermostat, and an alarm shall be given if, due to thermostat fault, the temperature reaches a defined limit. The instruction handbook shall contain information on appropriate actions. An expansion vessel or an expansion volume shall be fitted on the heating chamber or else the heating chamber shall be large enough to accommodate the increase in the volume of thermal fluid without overflow, associated with the maximum temperature setting of the thermostat. The vessel shall permit the level of thermal fluid at the regulator temperature to be checked, e.g. by direct reading. The flow of thermal fluid to the dry-cleaning machine shall be interrupted while the dry-cleaning machine is at standstill, e.g. by using automatic valves of the normally closed type. Advice shall be given in the instruction handbook for periodic cleaning of the venting pipe, e.g. once per year, to avoid an blockage. 4.2.4 Systems using pressurized fluids Components made of a fragile material (e.g. glass) and containing pressurized fluids at temperatures of more than 50 °C (e.g. steam, water or oil) shall be designed so as to prevent direct spraying in the event of leakage or rupture, or shall be shielded to protect people against harm. 4.2.5 Cold surfaces The temperature of handles shall comply with ISO 13732-3:2005, 5.3.

This also applies to machines equipped with an automatic balancing system. NOTE The force, F, from unbalanced mass to be presumed for floor strain and dimensioning of anchorage can be estimated by means of the formula given in 3.4.6. 4.5 Hazards due to neglect of ergonomic principles in machine design The design of the dry-cleaning machine shall take into account the ergonomics principles set out in ISO 12100-2:2003, 4.8, and EN 614-1. 4.6 Hazards related to emergency stop and lack of cooling At least one emergency stop device shall be provided at the main control position. The emergency stop system shall comply with the requirements of ISO 13850. The emergency stop shall cause all machine functions to cease except the provision of cooling medium. The emergency stop system shall have a stop category of 0 or 1 in accordance with ISO 13850:2006 and the related part of the control system shall present at least a performance level of PL = c in accordance with ISO 13849-1:2006. The main electrical switch may be used for the emergency stop function in as far as this does not compromise the provision of the cooling medium. In this case, the colours for identifying the switch shall comply with IEC 60204-1:2005, 10.7.4. 4.7 Hazards related to energy supply disconnection
Readily accessible and permanently operational provisions shall be made for disconnecting the dry-cleaning machine from all of its energy supplies. The disconnecting device(s) shall be lockable. The use of one or more of the devices shall not lead to an unsafe condition. Electrical devices shall comply with IEC 60204-1:2005, 5.3, while pneumatic devices shall comply with EN 983. If some of these devices have to be installed at the place of use, appropriate instructions shall be given in the instruction handbook. SIST EN ISO 8230-1:2009
