The wor
8、k 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-governme
9、ntal, 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. Draft International Standards adopted by the technical committees are circulated to the member bodies for votin
10、g. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard ISO 10472-4 was prepared by Technical Committee ISO/TC 72, Textile machinery and machinery for dry-cleaning and industrial laundering, Subcommittee SC 5, Industr
11、ial laundry and dry-cleaning machinery. ISO 10472 consists of the following parts, under the general title Safety requirements for industrial laundry machinery: Part 1: Common requirements Part 2: Washing machines and washer-extractors Part 3: Washing tunnel lines including component machines Part 4

14、 and to suggest possible state-of-the-art safety solutions. The extent to which hazards are covered is indicated in the scope of this part of ISO 10472. In addition, machinery should comply as appropriate with ISO/TR 12100-1 and ISO/TR 12100-2 for hazards which are not specifically referred to in th
15、is part of ISO 10472. All examples given in this part of ISO 10472 represent the state of the art. Equivalent solutions are acceptable, provided they attain at least the same safety level. The designer is presumed to have taken into account all the provisions of ISO 10472-1 before considering this p

17、 10472-4:1997(E) 1 Safety requirements for industrial laundry machinery Part 4: Air dryers 1Scope This part of ISO 10472 covers, together with ISO 10472-1, most significant hazards associated with air dryers, and in particular with tumble dryers having a net usable cage volume 160 l and tunnel finis
18、hers including associated conveyors and cabinet dryers. This part of ISO 10472 complements the basic requirements as laid down in ISO/TR 12100-1 and ISO/TR 12100-2. It also gives guidance to the designer on assessing the risks associated with the hazards (see EN 1050) and on selecting measures for a
19、ttaining the required safety level. This part of ISO 10472 does not apply to ancillary equipment. 2Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this part of ISO 10472.

43、hin the machine (see ISO 6182-1). To prevent very fast heat build-up in direct-heated machines, i.e. machines heated by gas or electricity without heat exchange, the heating shall be interlocked with the cage drive and air handling system such that the heat control is turned off when the cage rotati
44、on control or the air circulation control is turned off. 5.6.1.2Tunnel finishers and cabinet dryers The instruction handbook shall include a warning that work containing exothermic materials can cause fires in these machines. The machines shall be fitted with heat detection devices linked to an audi
45、ble signal to detect a potential fire. Gas-fired machines with an internal capacity greater than 200 garments shall be fitted with an integrated sprinkler system (see ISO 6182-1). 5.6.2Chemicals For tumble dryers, particularly those of the directly gas heated type, the instruction handbook shall inc
46、lude a warning regarding the possible presence of residual quantities of aggressive or decomposed chemicals in the load that may produce damage to the machine and harmful fumes (see EN 626-1). 5.7Failure of control systems The category of the safety-related part of the control system (see ISO 13849-
47、1:, clause 6) shall not be lower than category 1, except for the system controlling the entrance and exit of the tunnel finisher, which shall not be lower than category 2. 6Verification of safety requirements and/or measures Verification shall follow the general requirements of ISO 10472-1 and the p
