25、AND LABORATORY USE Part 2-061: Particular requirements for laboratory atomic spectrometers with thermal atomization and ionization 1 Scope and object This clause of Part 1 is applicable except as follows: 1.1 Scope 1.1.1 Equipment included in scope Replacement: This part of IEC 61010 applies to elec

26、trically powered laboratory atomic spectrometers with thermal atomization. NOTE 1 Examples include atomic absorption spectrometers, emission flame photometers, atomic fluorescence spectrophotometers, inductively coupled plasma spectrometers, microwave coupled plasma spectrometers and mass spectromet

27、ers, all with thermal atomization and ionization (including tubing and connectors which are provided by the manufacturer for connection to external supplies). NOTE 2 If all or part of the equipment falls within the scope of one or more other part 2 standards of IEC 61010 as well as within the scope

28、of this standard, it will also need to meet the requirements of those other part 2 standards. 1.1.2 Equipment excluded from scope Addition: Add as the first paragraph: This standard does not apply to thermal atomization detectors (flame ionization detectors) used in gas chromatography. 2 Normative r

29、eferences This clause of Part 1 is applicable. 3 Definitions This clause of Part 1 is applicable except as follows: Additional definitions: 3.2.101 SPRAY CHAMBER chamber in which droplets of sample in aerosol are allowed to separate so that the droplets of necessary size can be passed onward to the

30、burner, with the remainder draining to waste 3.2.102 GAS LOCK device to allow drainage of waste sample liquid, and to prevent unintentional escape of gas from the SPRAY CHAMBER through its drain outlet (see for example Figure 101) Page4 EN610102061:2003160-01-2061 IE2:C(300E) 5 3.5.101 FLASH-BACK ev

31、ent during which the flame travels back through the burner with the result that the gas in the mixing chamber is caused to ignite. 4 Tests This clause of Part 1 is applicable except as follows: Additional subclauses: 4.4.2.101 Sampling probe tip Any system designed to withdraw a sampling probe tip a

32、fter sampling has been completed shall be overridden, so as to leave the tip in its most exposed position when a sample vessel is removed. Exceptions: The withdrawal system need not be overridden if the sampling probe: a) cannot cause a HAZARD to the OPERATOR when it is exposed; b) is designed in su

33、ch a manner that no SINGLE FAULT can cause the tip to remain exposed after sampling has been completed. 4.4.2.102 Failure, or partial failure, of the MAINS supply The voltage of the power supply to the equipment from the MAINS supply shall first be reduced to just less than 90 % of the RATED voltage

34、, and shall then be switched off. 5 Marking and documentation This clause of Part 1 is applicable except as follows: Additional subclause: 5.1.101 Gas and liquid connections The following shall be unambiguously marked adjacent to the connector on the equipment (see 5.2): a) the identity of the gas o

35、r liquid; b) the maximum permitted pressure. NOTE Such markings may be specific (for example acetylene, propane, water) or generic (for example fuel gas, oxidant gas, coolant, waste liquid). Where no internationally recognized symbol (such as a chemical formula) exists, the equip- ment shall be mark

36、ed with symbol 14 of Table 1 together with an unambiguous text in English. The documentation accompanying the equipment shall provide an adequate translation of this text (where it is required) in the language of the country in which it is to be installed, to assure that the installer or OPERATOR is

37、 able to connect the equipment correctly. Conformity is checked by inspection. Page5 EN610102061:2003 6 160-01-2061 IE2:C(300E) 5.2 Warning markings Addition: Add the following new paragraph: Where hot gases or plasma emerge from equipment, the protective structure provided (for example a chimney, s

38、ee 10.1), shall be clearly marked by symbol 13 of Table 1, to indicate where excessively hot temperatures may exist. 5.4.3 Equipment installation Replacement: Replace 5.4.3 f) “requirements for special services” by the following new item f): f) requirements for connection of the equipment to supplie

39、s of air, fuel gas (for example hydrogen, acetylene, or propane) and oxidant (for example oxygen or nitrous oxide). See also 11.103; Addition: Add after the first paragraph the following new paragraph: The documentation shall state that the RESPONSIBLE BODY must ensure that the type of connector use

40、d at the outlet side of the gas-pressure regulator conforms to applicable national requirements; aa) requirements for liquid connection; bb) requirements for a fume extraction system to remove exhaust gases which may be hazardous; cc) requirements for appropriate filtering or other systems which may

41、 be necessary to trap hazardous sample residues present in the exhaust gas stream; NOTE In the case of equipment using only a propane flame in a ventilated room, and when it is known that samples will not leave any hazardous residues, it may not be necessary to provide an extraction system, since th

42、e exhaust gases from a propane flame will themselves not present any hazard. dd) the documentation shall state that the RESPONSIBLE BODY must carry out appropriate leakage tests necessary for safety on those gas and liquid connections which the OPERATOR is directed to assemble during installation, N

43、ORMAL USE, or maintenance; ee) instructions for examining, during installation and maintenance, parts of the external gas supply system including tubing connected to the equipment, in order to confirm that their condition is satisfactory, for example to detect stress cracks; NOTE Any special nationa

44、l regulations for the safe use of gases and gas cylinders need to be observed. ff) instructions for necessary provisions for collection of waste from the SPRAY CHAMBER, including the requirements for any waste container which may be specified by the manufacturer. NOTE 1 Connections on the outlet sid

45、e of gas regulators (from which tubing connects to the equipment) vary from country to country and are often covered by national regulations. Variations can include thread type, whether left-hand or right-hand, types of tubing and means of attachment. NOTE 2 Warning markings are specified in 5.1.5.1

46、 c), 5.1.101, 6.1.2 b), 6.5.1.2 g), 6.6.2, 7.2.c), 7.3, 10.1, 13.2.2. 5.4.4 Equipment operation Additions: Add the following two new items at the end of the first paragraph: aa) a reminder to the RESPONSIBLE BODY of the responsibility for the correct collection and disposal of waste materials, inclu

47、ding the necessity for: Page6 EN610102061:2003160-01-2061 IE2:C(300E) 7 1) a suitably sized waste container of appropriately resistant material for the collection of organic solvent waste; NOTE The proper disposal of waste materials is well documented by national authorities and it is these procedur

48、es that should be followed. This part 2 should only bring to the attention of the OPERATOR that potentially hazardous waste materials are present and must be properly disposed of in accordance with national (local) regulations. 2) provision for the removal into an appropriate exhaust system of any g

49、ases or vapours which may be produced in hazardous concentrations; bb) a list of fluids known by the manufacturer to be potentially unsafe if used with the equipment. Add a new second paragraph as follows: Documentation shall also indicate that this list cannot be taken to be exhaustive and that, in case of uncertainty about a specific fluid, that fluid shall not be used until confirmation by the manufacturer that it will not
