This standard has been prepared by Technical Committee ISO/TC 72 “Textile machinery and accessories”, Subcommittee SC 5 “Industrial laundry and dry-cleaning machinery and accessories” in c

5、ollaboration with Technical Committee CEN/TC 214 “Textile machinery and accessories” (Secretariat: SNV, Switzerland). The responsible German body involved in its preparation was the Normenausschuss Maschinenbau (Mechanical Engineering Standards Committee), Section Bekleidungs- und Ledertechnik. This

6、 standard contains specifications meeting the essential requirements set out in Annex I of the “Machinery Directive”, Directive 98/37/EC (valid until 28 December 2009), and the “revised Machinery Directive”, Directive 2006/42/EC, which takes effect on 29 December 2009, and which apply to dry-cleanin

7、g machines using combustible solvents that are either first placed on the market or commissioned within the EEA. This standard serves to facilitate proof of compliance with the essential requirements of the directives. Once this standard is cited in the Official Journal of the European Union, it is

8、deemed a “harmonized” standard and thus, a manufacturer applying this standard may assume compliance with the requirements of the Machinery Directive (“presumption of conformity”). The International and European Standards referred to in clause 2 and in the bibliography of this document have been pub

9、lished as the corresponding DIN EN or DIN EN ISO Standards with the same number. Amendments This standard differs from DIN EN ISO 8230:1998-03 as follows: a) The standard has been split into three parts: Part 1: Common safety requirements Part 2: Machines using perchloroethylene Part 3: Machines usi

10、ng combustible solvents b) The scope of the standard has been extended to include machines using combustible solvents. c) A new Part 3 has been included. d) A new Annex A “Noise measurement” has been included in Part 1.

This document (EN ISO 8230-3:2008) has been prepared by Technical Committee ISO/TC 72 “Textile Introduction This document is a type-C standard as stated in ISO 12100. The machine

26、ry 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

27、 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 8230-3:2008 (E) DIN EN ISO 8230-3:2009-05 41 Scope This part of ISO 8230 specifies safety requirements for dry-cleaning machines that

28、use a combustible solvent (CS), as defined in ISO 8230-1, 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 that are reasonably foreseeable by the manufacturer. This part of ISO 8230

29、, in conjunction with ISO 8230-1, deals with all significant hazards, significant 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 manufa

30、cturer to eliminate or reduce the risk. It deals with the following significant hazards specific to the use of CS: hazards related to the entire dry-cleaning machine (electrical hazards, explosion hazards); hazards relating to the machine (combustible solvent emission, explosion hazards during the c

31、leaning phase, explosion hazards during the drying phase); hazards relating to the distilling equipment (combustible solvent emission, explosion hazards). This part of ISO 8230 applies to machines manufactured after the date of its issue. 2 Normative references The following referenced documents are

38、 of the saturated vapour equals the lower explosion limit NOTE If the lower explosion point is unknown, it can be assumed that the CS does not form any explosive vapour air mixtures if temperatures do not exceed 15 K below the flash point. During washing and spinning, the formation of mist is possib

With the operating conditions existing in the cage, the ignition energy required for droplet size and density is not reached by means of the ignition sources to be expected. 3.4 flash point lowest temperature at which, under prescribed test conditions and in accordance with ISO 2719, a liquid re

43、rotective measures 4.1 General Dry-cleaning machines using CS shall comply with the safety requirements and/or protective measures of ISO 8230-1, in as far as these are not modified or completed by the requirements of this clause and other requirements of this part of ISO 8230. 4.2 Hazards related t

44、o the entire dry-cleaning machine 4.2.1 Electrical hazards In addition to the requirements of ISO 8230-1:2008, 4.9, the electrical equipment of the dry-cleaning machine shall comply with the following: electric wires shall not be laid on floors or similar places where CS is liable to gather; all com

45、ponents made of conductive materials shall be connected to the protective bonding circuit. 4.2.2 Explosion protective measures 4.2.2.1 Display of malfunctions Malfunctions in the field of explosion protection measures shall be displayed visually and signalled acoustically. 4.2.2.2 Measuring systems

46、4.2.2.2.1 General NOTE It is assumed that with two independent systems whose failure is detected, leading to the cut-off of the machine, a failure of both systems at the same time is not to be expected. The part of a control system of a dry-cleaning machine related to explosion protective measures s

47、hall be redundant or checked automatically so that failures cannot lead to an unsafe condition. Control systems shall be safeguarded against involuntary maladjustment or manipulation, for example, by a fixed measuring sensor or limited possibility for adjustments. Manipulation shall be discernible.

48、Malfunctions shall be recognized automatically by the control before the dry-cleaning machine can go to an unsafe condition. At the same time, the machine shall stop automatically. 4.2.2.2.2 Concentration measuring instruments Oxygen-measuring instruments shall be checked in accordance with EN 50104

49、:2004, and CS measuring instruments shall be checked in accordance with EN 61779-1:2000 and EN 61779-4:2000. EN ISO 8230-3:2008 (E) DIN EN ISO 8230-3:2009-05 7The correct functioning of all concentration measuring systems shall be checked automatically during each working cycle. Faults shall entail the automatic stop of the dry-cleaning machine so that safe operating conditions are achieved.
