This Technical Specification specifies test methods for a) thermal plasma torch systems: - arc plasma systems; - inductive plasma systems; b) installation using thermal plasma torch systems: - spraying equipment; - solid, liquid and gaseous charge heating and thermochemical treatment equipment. Test methods for plasma torches for welding, cutting and allied processes are specified in IEC 60974-7. The object of this specification is to standardize the test methods and conditions for determining the main parameters and technical characteristics of thermal plasma torch systems and of installations (or equipment) using one or more plasma torch systems. Not all the tests specified are applicable to every type of equipment, covered by this specification. It is necessary to select those tests which are applicable to a specified plasma torch system or installation. This selection is effective in the specification. Safety requirements for systems and installations or equipment specified in a) and b) are given in IEC/TS 60519-5.

8 热电偶装置.一些关于热电偶选择,安装和操作指南 - 摘要

A heat meter is composed of three parts, a flow sensor, a temperature sensor pair and a calculator.The calculator is a unit which calculates volumes and energy consumption using the values from thetemperature sensors and the flow sensor.The most common type of temperature sensor is a resistance thermometer of platinum type Pt 100, Pt500 or Pt 1000. The sensors measure the temperature difference between the incoming and outgoingliquid .The flow sensor is probably the most troublesome assembly of the heat meter. Despite an accuracyrequirement of only 4-10% it is very easy to fall outside these limits. In order to counter these effects asfar as possible, there follows a summary of the various types of flow sensor and their advantages anddisadvantages.The sizing of meters to match their required duty frequently turns out to have been incorrectly estimatedwhen the heating plant commences operation. In most cases heat meters that are too large for their eventual duty are specified and accuracy at low load suffers as a result. Whilst this paper will give someguidance on essentials, it is felt that more information on this topic would be welcomed.Heat meter accuracies at times of rapidly changing heat demand are unlikely to be high. Whilst at timesof low demand the effect of meter inaccuracy in terms of lost revenue is likely to be small, rapid changesinvolving high demands on the network may possibly have important implications in lost revenue if meterreaction to rapid changes is slow. Research into the subject seems to have been largely neglected sofar.The most commonly used types of flow sensors have been listed in Annex B and the effect on accuracyof different types of disturbances for each of the listed types of flow sensors are considered.There is little information on the effects of flow and flow disturbances on the service life of the flowsensor, as distinct from its effect on the sensor’s accuracy. To be welcomed, therefore, is the long termresearch project on this topic initiated in Germany which should result in useful data.

9 电力工程.三相交流系统用典型部件.量和变换 - 摘要

This International Standard deals with transformations from original quantities into modalquantities for the widely used three-phase a.c. systems in the field of electric powerengineering.The examination of operating conditions and transient phenomena in three-phase a.c.systems becomes more difficult by the resistive, inductive or capacitive coupling between thephase elements and line conductors. Calculation and description of these phenomena inthree-phase a.c. systems are easier if the quantities of the coupled phase elements and lineconductors are transformed into modal quantities. The calculation becomes very easy if thetransformation leads to decoupled modal systems. The original impedance and admittancematrices are transformed to modal impedance and admittance matrices. In the case ofdecoupling of the modal quantities, the modal impedance and admittance matrices becomediagonal matrices.

10 机械安全.电敏保护设备.第3部分:有源光电子保护器件对漫反射响应(AOPDDR)的特殊要求 - 摘要

SAFETY OF MACHINERY –ELECTRO-SENSITIVE PROTECTIVE EQUIPMENT –Part 3: Particular requirements for Active Opto-electronicProtective Devices responsive toDiffuse Reflection (AOPDDR)Replacement:This part of IEC 61496 specifies additional requirements for the design, construction andtesting of non-contact electro-sensitive protective equipment (ESPE) designed specifically todetect persons as part of a safety related system, employing active opto-electronic protectivedevices responsive to diffuse reflection (AOPDDRs) for the sensing function. Special attentionis directed to requirements which ensure that an appropriate safety-related performance isachieved. An ESPE may include optional safety-related functions, the requirements for whichare given both in Annex A of this part and in Annex A of IEC 61496-1.This part does not specify the dimensions or configurations of the detection zone and itsdisposition in relation to hazardous parts for any particular application, nor what constitutes ahazardous state of any machine. It is restricted to the functioning of the ESPE and how itinterfaces with the machine.AOPDDRs are devices that have a detection zone specified in two dimensions whereinradiation in the near infrared range is emitted by a transmitter element(s). When the emittedradiation impinges on an object (for example, a person or part of a person), a portion of theemitted radiation is reflected to a receiving element(s) by diffuse reflection whereby thepresence of the object can be detected.Excluded from this part are AOPDDRs employing radiation of wavelength outside the range820 nm to 946 nm, and those employing radiation other than that generated by the AOPDDRitself. For sensing devices that employ radiation of wavelengths outside this range, this partmay be used as a guide. This part is relevant for AOPDDRs having a stated detection capabilityin the range from 30 mm to 200 mm. AOPDDRs intended for use as trip device using wholebodydetection with normal approach to the detection zone and having a stated detectioncapability not exceeding 200 mm shall meet the requirements of Clause A.12. AOPDDRsintended for a direction of approach normal to the detection zone and having a stated detectioncapability in the range from 30 mm to 70 mm shall meet the requirements of Clause A.13.This part may be relevant to applications other than those for the protection of persons, forexample, for the protection of machinery or products from mechanical damage. In thoseapplications, different requirements may be necessary, for example when the materials thathave to be recognized by the sensing function have different properties from those of personsand their clothing.This part does not deal with electromagnetic compatibility (EMC) emission requirements.Opto-electronic devices that perform only one-dimensional spot-like distance measurements,for example, proximity switches, are not covered by this part.
