5 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 was prepared by Technical Committee ISO/TC 131, Transmissions hydrauliques et pneumatiques, Subcommittee SC 5, Appareils de régulation et de distribution et leurs composants. This second/third/... edition cancels and replaces the first/second/... edition (), [clause(s) / subclause(s) / table(s) / figure(s) / annex(es)] of which [has / have] been technically revised. ISO 5782 consists of the following parts, under the general title Pneumatic fluid power Compressed air filters: Part 1: Main Characteristics to be included in supplier's literature and product-marking requirements Part 2: Test methods to determine the main characteristics to be included in supplier's literature iv ISO 2015 All rights reserved

6 Introduction In pneumatic fluid power systems, power is transmitted and controlled through air under pressure within a circuit. Where mechanical filtration of the air media is desired, filters are components designed to remove solid and liquid contaminants from compressed air. ISO 2015 All rights reserved v

8 COMMITTEE DRAFT ISO/CD Pneumatic fluid power Compressed air filters Part 1: Main Characteristics to be included in supplier's literature and product-marking requirements 1 Scope This part of ISO 5782 specifies which characteristics of compressed air filters are to be included in the supplier's literature. It also specifies product-marking requirements. This part of ISO 5782 applies to compressed air filters, constructed from light alloys (aluminium, etc.), zinc diecast alloys, brass, steel and plastic, with a rated pressure of up to kpa (16 bar) and a maximum temperature of 80 C, designed to remove solid and liquid contaminants from compressed air by mechanical means. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this part of ISO At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this part of ISO 5782 are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below. Members of IEC and ISO maintain registers of currently valid International Standards.

The pressure drop at additional inlet pressures, such as described in ISO 2944, or elsewhere, may also be recorded. Results shall be presented in either graphical or tabular form. Typical examples are given in Figure 2 and Table 1.

16 Annex B (informative) Air purity classification from ISO 8573 Purity Class Solid Particulate (1 st digit) Water (2 nd digit) Oil (3 d digit) Max. No. of particles per m 3 Mass Humidity Liquid water Concentration Particle size in μm Concentration (Note #) mg/m mg/m 3 Pressure Concentration dewpoint g/m 3 0 As specified by the equipment user or supplier and more stringent than class , ºC ,000 6, ºC ,000 1,000 Not -20 ºC Not ,000 applicable +3 ºC applicable , ºC ºC Not applicable 7 Not applicable 10 Not applicable X >10 >10 NOTE #: this is a combined concentration of oil aerosol, oil liquid, & oil vapour. A 3 digit code is used to designate the purity class: ABC; where: A is the purity class for solid particulates, B is the purity class for water, and C is the purity class for oil contamination. A hyphen is substituted for a letter if there is no specification. Solid particles: Purity classes 1-5 are common for applications where particulate contamination control is very specific (i.e. clean rooms, paint spray, breathing apparatus, etc.). Purity classes 6-7 are common for general pneumatic applications in shops, factories, construction sites, etc. Water: Purity classes 1-6 are used when the dew point is the desired characteristic to be measured or controlled applications where ambient temperature or the temperature of expanding air is a factor, and condensation is to be avoided. Purity classes 7-9 are used for applications where the liquid water concentration must be measured or controlled applications where air becomes intermingled with the process (i.e. food processing, powder transport, paint spray, etc.). Oil: Purity classes 1-4 describe the concentration of liquid oil particulate (mist). This typically occurs as oil carryover from the air compressor and is removed with coalescing filters. The amount of removal depends on the grade of filter, corresponding to the purity class. ISO 2015 All rights reserved 9
