Fire, however, is a complex phenomenon and its behaviour, when associated with a cable run, is a function of the characteristics of the cable materials, the method of installation, and the environment in which it is used. 1、着火风险评估方法 试验结果为单条电力电缆暴露在设定的外部火源时起火和火势蔓延的可能性提供了直接的数据。然而，火灾是一种 COPYRIGHT 31 AS/NZS 5000.1:2005 复杂的现象，当与电缆敷设路径有关时，其特性是电缆材料特性、安装方法以及所处环境的一个函数。 Consequently, no single test can give a full assessment of the fire hazard under all possible fire conditions. There must be a constant awareness of these interrelated factors and effects of important variables in using this test to assess the fire hazard in any particular situation (e.g. in high vertical runs of bunches of cables). Special installation precautions may have to be taken as it cannot be assumed that a bunch of cables will behave in the same way as a single cable. 因此，单一的试验结果并不能全面的评估各种可能燃烧条件下的起火风险。必须持续关注这些相关的因素以及运用这种试验结果评估各种特殊情况下(如处于架空垂直走向的多条电缆)重要变量的影响。当认定多条电缆和单条电缆的运行情况不一致时，必须采取特殊的安装,预防措施。 2 Cautionary note When reporting the results, the following cautionary note should be added: Individual items of this test report should not be quoted in isolation as proof of product acceptability nor applied to directly assess performance under conditions other than as envisaged by the reference specification, e.g. individual fire tests to prove an overall acceptable fire hazard level. 2、警告说明 报告结果时，应附注下列警告说明: 本试验报告的单一数据项不应作为产品认可证据而单独引用，也不应直接用于评估不同条件下的产品性能(由参考规范做出的设想除外)，如用单一的起火试验证明整体的起火风险接受水平。 COPYRIGHT AS/NZS 5000.1:2005 32 APPENDIX A 附件A PURCHASING GUIDELINES 采购指南 (Informative)(参考性) A1 GENERAL A1 总则 Australian/New Zealand Standards are intended to include the technical requirements for relevant products, but do not purport to comprise all the necessary provisions of a contract.

This sometimes causes problems. The calculated nominal diameters are not necessarily the same as the actual values achieved in production. In borderline cases, queries can arise if the thickness of a covering does not correspond with the actual diameter, because the calculated diameter is slightly different. Variations in conductor makeup and shaped conductor dimensions between manufacturers, and different methods of calculation cause differences in nominal diameters, and may therefore lead to variations in the thicknesses of coverings used on the same basic design of cable. 通过“阶表”可以看出，护层和铠装等电缆覆层的厚度通常与电缆标称直径有关。这样，有时也会产生一些问题。标 称直径计算值不一定与运行中得到的实际值相符。在介于两者之间的情况下，由于标称直径计算值稍微出现差异， 因此如果电缆覆层的厚度与实际直径不一致，则会引起相关方的质询。导体结构和制造商之间定形导体尺寸的变化 以及不同的计算方法都会导致标称直径出现差异，从而会致使用于相同电缆初步设计的电缆覆层厚度产生变化。 To avoid these difficulties, the fictitious calculation method described in this Appendix was invented. The idea is to ignore the shape and degree of compaction of conductors and to calculate diameters from equations based on the cross-sectional area of conductors, insulation thickness and number of cores. Thicknesses of sheath and other coverings are then related to these diameters by equations or by tables. The method of calculating fictitious diameters is precisely specified and there is no ambiguity about the thicknesses of coverings to be used, which are independent of slight differences in manufacturing practices. This standardizes cable designs, thicknesses being precalculated and specified for each size of cable. 为了避免上述问题，从而引出了本附件所述的虚拟计算方法。这种计算方法忽略了导体的形状和密实度，根据导体 的截面积、绝缘厚度以及芯线数量，通过公式计算直径。因此，护层和其他覆层的厚度与公式计算得出或查表得出 的这些直径有关。虚拟直径的计算方法明确的予以规定，从而使采用的覆层厚度不存在多值性的现象，这样即使制 造方法存在细小差异，也不会对计算结果产生影响。这种计算方法规范了电缆设计、预先计算得出的厚度以及各种 尺寸的电缆厚度。 The fictitious calculation method is only used to determine dimensions of cable components other than insulation. It is not a replacement for the calculations of normal diameters required for practical purposes, which should be calculated separately. 虚拟计算方法只用于确定电缆组件的尺寸，而并非是绝缘体的尺寸。它并不是取代实际工作中所需正常直径的计算 ，而后者的计算工作应单独进行。 B2 GENERAL B2 总则 This Appendix adopts the fictitious method of calculating thicknesses of various coverings in a cable so that any differences which can arise in independent calculations are eliminated, e.g. the assumption of conductor dimensions and the unavoidable differences between nominal and actually achieved diameters. COPYRIGHT 35 AS/NZS 5000.1:2005 本附件采用虚拟的方法计算电缆中各种覆层的厚度，这样在单独计算中可能出现的各种差异将得以消除，如导体尺 寸的推测值和标称直径和实际运行中得出直径之间无法避免的差异。 All thickness values and diameters shall be rounded to the first decimal place according to the rules given in Appendix C. 根据附件C中的规定，所有的厚度值和直径必须四舍五入精确到小数点后一位。 Binder tapes are ignored in this calculation method. 本计算方法中，粘结带忽略不计。 B3 METHOD B3 方法 B3.1 Conductors B3.1 导体 The fictitious diameter (dL) of conductor, calculated from the respective nominal cross- sectional area, irrespective of the conductor shape or compactness to be used in practice, is given in Table B1. 忽略导体形状或实际工作中的密实度，根据相应的标称截面积计算得出的导体虚拟直径(dL)如表B1所示。 COPYRIGHT AS/NZS 5000.1:2005 36 TABLE B1 表B1 FICTITIOUS DIAMETER OF CONDUCTOR 导体虚拟直径 Nominal Nominal Fictitious diameter Fictitious diameter cross-sectional area cross-sectional area (dL) (dL) of conductor of conductor 虚拟直径(dL) 虚拟直径(dL) 导体标称截面积 导体标称截面积 mm mm 2 2 mmmm单位:毫米 单位:平方毫米 单位:平方毫米 单位:平方毫米 0.5 0.8 185 15.3 1.0 1.1 240 17.5 1.5 1.4 300 19.5 2.5 1.8 380 22.0 4 2.3 400 22.6 6 2.8 480 24.7 10 3.6 500 25.2 16 4.5 600 27.6 25 5.6 630 28.3 35 6.7 740 30.7 50 8.0 800 31.9 70 9.4 960 35.0 95 11.0 1 000 35.7 120 12.4 1 200 39.1 150 13.8 B3.2 Cores B3.2 芯线 The fictitious diameter of a core (D) of the respective conductor cross-sectional area is as follows: c 相应导体截面积的芯线虚拟直径(D)计算如下: c Where 其中 ti = the nominal insulation thickness as specified in Table 1 ti为表1中规定的标称绝缘厚度 If a metallic screen or a concentric conductor is applied, a further addition shall be made in accordance with Paragraph B3.5. 如果采用金属屏蔽或同心导体，则必须根据B3.5条中的规定额外增加绝缘的厚度。 B3.3 Diameter over laid-up cores B3.3 扭绞芯线的直径 The fictitious diameter (Df) over laid-up cores is given by the following: 扭绞芯线上的虚拟直径(Df)由下列公式计算得出: (a) For cables comprising cores with all conductors of the same nominal cross-sectional area (a)由所有相同标称截面积导体芯线组成的电缆 COPYRIGHT 37 AS/NZS 5000.1:2005 Where 其中 k = the coefficient given in Table B2 corresponding to the number of cores in the cable k为与表B2中提供的电缆芯线数量一致的系数 (b) For cables comprising cores with conductors of differing nominal cross-sectional area, the greater of the two values calculated from the following equations: (b)由不同标称截面积导体芯线组成的电缆，两个不同截面积中，大截面积导体芯线的虚拟直径采用下列公式计算得出: Where 其中 = the coefficient given in Table B2 corresponding to the total number k of cores in the cable k为与表B2中提供的电缆芯线总数一致的系数 Dca = the calculated average fictitious core diameter (including any metallic screen, etc. applied on each core) Dca为平均虚拟芯线计算直径(包括各芯线上使用的金属屏蔽等) See Examples 1 and 2. 请参阅示例1和示例2。 Where 其中 k = the coefficient given in Table B2 corresponding to the number of full size (main) cores in cable k为与表B2中提供的电缆最大尺寸(主)芯线一致的系数 Dc1 =fictitious diameter of the full size (main) cores (including any metallic screen or covering applied on each core) Dc1为最大尺寸(主)芯线的虚拟直径(包括各芯线上使用的金属屏蔽或覆层) Example 1 示例1 For a 4-core cable with one insulated conductor of reduced nominal cross-sectional area— 其中一根绝缘导体为小标称截面积的4芯电缆: Where 其中 Dc1 =fictitious diameter of the full size (main) cores Dc1 为最大尺寸(主)芯线的虚拟直径 Dc2 =fictitious diameter of the reduced size core COPYRIGHT AS/NZS 5000.1:2005 38 Dc2 为小截面积芯线的虚拟直径 Example 2 示例2 For a 5-core cable with two insulated conductors of reduced nominal cross-sectional area, e.g. a reduced size neutral and a reduced size earth— 其中两根绝缘导体为小标称截面积的5芯电缆，如一根小截面积的中性线和一根小截面积的接地线: Where 其中 Dc1 =fictitious diameter of the full size (main) cores Dc1 为最大尺寸(主)芯线的虚拟直径 Dc2 =fictitious diameter of the neutral core Dc2 为中性芯线的虚拟直径 Dc3 =fictitious diameter of the earth core Dc3 为接地芯线的虚拟直径 COPYRIGHT 39 AS/NZS 5000.1:2005 TABLE B2 表B2 FICTITIOUS LAY-UP DIAMETER COEFFICIENT FOR MULTICORE CABLES 多芯电缆的虚拟扭绞直径系数 Lay-up Lay-up Lay-up Number Number Number diameter diameter diameter of cores of cores of cores coefficient coefficient coefficient (k) (k) (k) 芯线数量 芯线数量 芯线数量 扭绞直径系数 扭绞直径系数 扭绞直径系数 (k) (k) (k) 2 2.00 18 5.00 38 7.33 3 2.16 18* 7.00 39 7.33 4 2.42 19 5.00 40 7.33 5 2.70 20 5.33 41 7.67 6 3.00 21 5.33 42 7.67 7 3.00 22 5.67 43 7.67 7* 3.45 23 5.67 44 8.00 8 3.45 24 6.00 45 8.00 8* 3.66 25 6.00 46 8.00 9 3.80 26 6.00 47 8.00 9* 4.00 27 6.15 48 8.15 10 4.00 28 6.41 49 8.15 10* 4.40 29 6.41 50 8.15 11 4.00 30 6.41 51 8.41 12 4.16 31 6.70 52 8.41 53 至57 12* 5.00 32 6.70 8.70 58 至61 13 4.41 33 6.70 9.00 14 4.41 34 7.00 15 4.70 35 7.00 16 4.70 36 7.00 17 5.00 37 7.00 * Cores assembled in one layer. * 布置在一层中的芯线。 B3.4 Bedding B3.4垫层 The fictitious diameter over the bedding (DB) is equivalent to the fictitious diameter under any metallic layer and is given by the following equation: 垫层上的虚拟直径(DB)与各种金属层下的虚拟直径相等，并由下列公式计算得出: For a bedding complying with Clause 8 or for a sheath under armour complying with Clause 13— 符合第8条的垫层或符合第13条铠装下的护层: DB =DuB + 2tB . . .

C1 “虚拟计算方法”中数值的四舍五入 The rules set out in this Appendix shall apply when rounding numbers in calculating fictitious diameters and determining dimensions of component layers in accordance with Paragraph B3, Appendix B. 当根据附件B中B3条的规定，计算虚拟直径和确定组件层尺寸而需要四舍五入时，必须遵守本附件中规定 的规则。 When the calculated value at any stage has more than one decimal place, the value shall be rounded to one decimal place, i.e. to the nearest 0.1 mm. The fictitious diameter at each stage shall be rounded to 0.1 mm and, when used to determine the thickness or dimension of an overlying layer, it shall be rounded before being used in the appropriate equation or table. The thickness calculated from the rounded value of fictitious diameter shall in turn be rounded to 0.1 mm, as required in Paragraph B2, Appendix B. 当各级计算值的小数点超过一位时，必须对其进行四舍五入而精确到一位小数点，如精确到0.1mm。各级虚 拟直径必须四舍五入而精确到0.1mm。当虚拟直径用于确定覆层的厚度或尺寸时，在将其用于相应的公式或 表格之前，必须进行四舍五入。根据附件B中B2的规定，由虚拟直径舍入值计算得出的厚度也必须进行四 舍五入而精确到0.1mm。 To illustrate these rules, the following practical examples are given: 为了说明这些规则，列举了如下示例: (a) When the figure in the second decimal place before rounding is 0, 1, 2, 3 or 4, then the figure retained in the first decimal place remains unchanged (rounding down). (a)当四舍五入前小数点第二位数为0、1、2、3或4时，则数值保留一位小数不变(四舍)。 Examples: 2.12 ~2.1 2.449 ~2.4 25.0478 ~ 25.0 示例:2.12~2.1 2.449~2.4 25.0478~25.0 (b) When the figure in the second decimal place before rounding is 9, 8, 7, 6 or 5, then the figure in the first decimal place is increased by one (rounding up). (b)当四舍五入前小数点第二位数为5、6、7、8或9时，则小数点第一位的数字进一位(五入)。 Examples: 2.17 ~ 2.2 2.453 ~ 2.5 30.050 ~ 30.1 示例:2.17~2.2 2.453~2.5 COPYRIGHT AS/NZS 5000.1:2005 44 30.050~30.1 C2 ROUNDING OF NUMBERS FOR OTHER PURPOSES C2 其他情况的数值四舍五入 For purposes other than those set out in Paragraph C1, values may have to be rounded to more than one decimal place. This may occur, for example, when calculating the average value of several measurement results, or the minimum value by applying a percentage tolerance to a given nominal value. In such cases, rounding shall be carried out to the number of decimal places specified in the relevant clauses. 除了C1条中规定的情况外，数值四舍五入必须保留一位以上的小数，例如当通过将百分比公差应用于给定标 称值以计算几种测量结果的平均值或最小值时。在这种情况下，必须四舍五入到相关规定设定的小数点位数 。 The method of rounding shall then be as follows: 此时，四舍五入方法如下所示: (b) If the last figure to be retained is followed, before rounding, by 0, 1, 2, 3 or 4, it shall remain unchanged (rounding down). (b)如果四舍五入前保留的最后位数为0、1、2、3或4时，数值必须保持不变(四舍)。 (c) If the last figure to be retained is followed, before rounding, by 9, 8, 7, 6 or 5, it shall be increased by 1 (rounding up). (c)如果四舍五入前保留的最后位数为5、6、7、8或9时，数值必须进一位(五入)。 Examples: 2.449 ~ 2.45 Rounded to two decimal places 2.449 ~ 2.4 Rounded to one decimal place 25.0478 ~ 25.048 Rounded to three decimal places 25.0478 ~ 25.05 Rounded to two decimal places 25.0478 ~ 25.0 Rounded to one decimal place 示例: 2.449 ~ 2.45 四舍五入保留两位小数 2.449 ~ 2.4 四舍五入保留一位小数 25.0478 ~ 25.048 四舍五入保留三位小数 25.0478 ~ 25.05 四舍五入保留两位小数 25.0478 ~ 25.0 四舍五入保留一位小数 45 AS/NZS 5000.1:2005 AMENDMENT CONTROL SHEET 修订控制图表 AS/NZS 5000.1:2005 AS/NZS 5000.1:2005 Amendment No. 1 (2006) 2006年第一次修订 REVISED TEXT SUMMARY: This Amendment applies to Clause 16.1. 修订内容摘要:修订第16.1条。 Published on 7 December 2006. 2006年12月7日出版。 Standards Australia 澳大利亚标准局 Standards Australia is an independent company, limited by guarantee, which prepares and publishes most of the voluntary technical and commercial standards used in Australia.
