35、rement and test 1 Scope and object 1.1 Scope This part of IEC 61010 applies to hand-held and hand-manipulated PROBE ASSEMBLIES of the types described below, and related accessories which are intended for professional, industrial process, and educational use. These PROBE ASSEMBLIES are for use in the

36、 interface between an electrical phenomenon and test or measurement equipment. They may be fixed to the equipment or be detachable accessories for the equipment. a) Low-voltage and high-voltage, non-attenuating PROBE ASSEMBLIES (type A). Non-attenuating PROBE ASSEMBLIES that are RATED for direct con

37、nection to voltages exceeding 33 V r.m.s. or 46,7 V peak or 70 V d.c., but not exceeding 63 kV. They do not incorporate active components, nor are they intended to provide a voltage divider function or a signal conditioning function, but they may contain passive non-attenuating components such as fu

38、ses. b) High-voltage attenuating or divider PROBE ASSEMBLIES (type B). Attenuating or divider PROBE ASSEMBLIES that are RATED for direct connection to secondary voltages exceeding 1 kV but not exceeding 63 kV. The divider function may be carried out wholly within the PROBE ASSEMBLY, or partly within

39、 the test or measurement equipment to be used with the PROBE ASSEMBLY. c) Low-voltage attenuating or divider PROBE ASSEMBLIES (type C). Attenuating, divider or other signal conditioning PROBE ASSEMBLIES for direct connection to voltages exceeding 33 V r.m.s or 46,7 V peak or 70 V d.c., but not excee

40、ding 1 kV r.m.s. or 1,5 kV d.c. The signal conditioning function may be carried out wholly within the PROBE ASSEMBLY, or partly within the test or measurement equipment intended to be used with the PROBE ASSEMBLY. NOTE PROBE ASSEMBLIES which are not within the definitions of types A, B, C, or D, or,

41、 which are designed to be powered from a low-voltage mains supply, or include other features not specifically addressed in this standard may also need to meet the relevant requirements of other parts of IEC 61010 6 1) . 1.2 Object 1.2.1 Aspects included in scope The object of this standard is to ens

42、ure that the design and methods of construction used provide adequate protection for the OPERATOR and the surrounding area against: a) electric shock or burn (see clauses 6, 10 and 11); b) mechanical HAZARDS (see clauses 7, 8 and 11); _ 1) Figures in square brackets refer to the bibliography. d) Low

43、-voltage attenuating and non-attenuating PROBE ASSEMBLIES (type D), that are RATED for direct connection only to voltages not exceeding 33 V r.m.s., or 46,7 V peak, or 70 V d.c., and are suitable for currents exceeding 8 A. ! “ BS EN 61010-031:2002+A1:2008 EN 61010-031:2002+A1:2008 (E) Page 5 BSI 20

44、101.2.2 Aspects excluded from scope This standard does not cover a) reliable function, performance or other properties of the PROBE ASSEMBLY; b) effectiveness of transport packaging; c) servicing (repair); d) protection of servicing (repair) personnel. NOTE Servicing personnel are expected to be rea

45、sonably careful in dealing with obvious HAZARDS, but the design should protect against mishap in an appropriate manner, and the service documentation should point out any residual HAZARDS. 1.3 Verification This standard also specifies methods of verifying, through inspection and TYPE TESTING, that t

46、he PROBE ASSEMBLY meets the requirements of this standard. 1.4 Environmental conditions This standard applies to PROBE ASSEMBLIES designed to be safe at least under the following conditions: a) altitude up to 2 000 m, or above 2 000 m if specified by the manufacturer; b) temperature 5 C to 40 C; or

47、below 5 C or above 40 C if specified by the manufacturer; c) maximum relative humidity 80 % for temperatures up to 31 C decreasing linearly to 50 % relative humidity at 40 C; d) applicable RATED POLLUTION degree. 2 Normative references The following normative documents contain provisions which, thro
