27、, Uncontrolled Copy, (c) BSI EN 61115:1993 BSI 01-20003 Introduction Most process or environmental analyzers are designed to work within specified limits of the properties of the sample fluid (e.g. pressure, dew-point) at the sample inlet as well as the outlet 1,2. Moreover, process analyzers may ne
28、ed auxiliary fluids or other utilities for their correct function. It is the purpose of a sample handling system to connect one or more process analyzers with one or more source fluids and the environment, so that the requirements of the analyzer are met, and so that it is possible for the analyzer
29、to work properly over an acceptable period of time with an economically justified amount of maintenance work. (See Annex A for the description of the purpose, functions and properties of sample handling systems.) Sample handling systems may fulfill the following functions 1: sample extraction; sampl
30、e transport; sample conditioning; exhaust stream disposal; supply of utilities; sample stream switching; performance monitoring and control. Some of the functions can be completely or partly fulfilled by components which are integral parts of an analyzer or which are external to the sample handling
31、system. For the purpose of this standard these components are not considered part of the sample handling system. The design of a sample handling system depends on the properties of the source fluid, the process analyzer, and the disposal points. Furthermore, the design depends on the properties requ
32、ired for the complete measuring device. Testing a sample handling system is very important. Due to the variety of system configurations and requirements for a system, many different test procedures are applied in practice, but in this standard only the test procedures which are used in most cases ar
33、e specified. User and manufacturer may agree on additional test procedures, but these are not covered in this standard. 1 Scope and object 1.1 Scope This International Standard specifies the tests which should be carried out to determine the functional performance of sample handling systems. In addi
34、tion it specifies the information to be provided by the manufacturers and users of such systems. It is applicable to: a) systems handling gaseous or liquid samples for process analyzers used for any ultimate purpose, e.g. process control, emission, ambient air monitoring, etc.; b) complete systems a
35、nd system components; c) power supplies and instrumentation for providing and controlling other utilities necessary for process analyzers or sample handling system components, only in so far as they are a functional part of the system; d) facilities for maintaining system performance; e) facilities
36、for maintaining the performance of the process analyzer if these are part of the sample handling system and not the analyzer. NOTE 1This standard has been prepared in accordance with the general principles set out in IEC 359. NOTE 2Requirements for general principles concerning quantities, units and
37、 symbols are given in ISO 1000 and recommendations for the use of their multiples and of certain other units in ISO 31. 1.1.1 Aspects excluded from scope This standard does not cover: general aspects of process analyzers (see IEC 746 for electrochemical analyzers); NOTEAn IEC standard is in preparat
38、ion for gas analyzers. electric safety requirements (see IEC 348); safety aspects concerning explosive or toxic hazards; aspects concerning applications where regulations or legal metrology are involved, such as atmospheric pollution. For such aspects more elaborate work going on inside ISO such as
39、ISO 6712 applies; requirements for output signals (see IEC 381-1 and IEC 381-2); influence of environmental conditions (see IEC 68). 1.1.2 Equipment excluded from scope This standard does not apply to: systems for handling solid samples; equipment intended for use in explosive gas atmospheres (see I
40、EC 79-0 to IEC 79-12).

41、performance of sample handling systems for process analyzers; to specify the tests which, in most cases, should be performed to determine the functional performance of sample handling systems; to specify what information should be available for the manufacturer of sample handling systems. This infor
42、mation may be provided by the user or the manufacturer of process analyzers or by the manufacturer of sample handling system components; to specify what information should be available for the user of sample handling systems. 2 Normative references The following standards contain provisions which, t

47、d which depend on its composition NOTEFor on-line or extractive process analyzers a sample stream is extracted from the source fluid and transported to the analyzer. With an in-line or in situ analyzer the measurement is performed within the source fluid. 3.1.2 sample handling system a system which
48、connects one or more process analyzers with the source fluid, disposal points and utilities NOTE 1A sample handling system may extract the required sample stream from one or more source fluids and condition it in order to meet all the input requirements of the process analyzer so that an accurate me
49、asurement of the properties under investigation is possible. The system may also ensure the appropriate disposal of exhaust streams and the supply of utilities as necessary. Instrumentation for ensuring the proper function of a sample handling system component or for facilitating maintenance work is considered part of the sample handling system if it is a functional part of it.
