IEC 60331-3:20 18 RLV包含国际标准及其红线版本。红线版本只有英文版本。Redline版本为您提供了一种快速简单的方法来比较该标准与其前一版本之间的所有变化。红线版本不是IEC官方标准，只有标准的当前版本才被视为官方文件。 IEC 60331-3:20 18规定了在金属外壳中测试以及在规定条件下遭受火灾和机械冲击时需要保持电路完整性的电缆的测试方法。本文件适用于额定电压不超过600 V/1 000 V的电缆，包括额定电压低于80 V的电缆、金属数据和电信电缆以及光纤电缆。它旨在测试总直径不大于20 mm的电缆。本文件包括与额定电压不超过600 V/1 000 V（含600 V/1 000 V）的电力和控制电缆相关的具体故障点、连续性检查安排、测试样品、测试程序和测试报告的详细信息。IEC 60331-3未给出与金属数据、电信电缆和光纤电缆相关的具体故障点、连续性检查安排、测试样品、测试程序和测试报告的详细信息。虽然范围仅限于额定电压不超过0,6/1,0 kV的电缆，但经制造商和买方同意，该程序可用于额定电压不超过1,8/3（3,3）kV的电缆，前提是使用合适的保险丝。不假设通过该方法成功评估的电缆也将通过IEC 60331-1或IEC 60331-2的要求。根据这两个标准中的任何一个进行测试都将单独进行。此类附加性能可通过根据IEC 60331-1:20 18条款11或IEC 60331 2:20 18条款11的标记来识别。第二版取消并取代了2009年出版的第一版。它构成技术修订。与上一版相比的重大技术变更如下: -将范围扩展至包括金属数据和电信电缆以及光纤电缆，尽管IEC 60331未提供与金属数据和电信电缆以及光纤电缆相关的具体故障点、连续性检查安排、测试样本、测试程序和测试报告的详细信息-3; -改进了对测试环境的描述； -强制使用质量流量计/控制器作为精确控制燃料和空气到燃烧器的输入流速的手段； -改进了测试报告中包含的信息的描述。

IEC 60331-3:2018 RLV contains the International Standard and its Redline version. The Redline version is available in English only. The Redline version provides you with a quick and easy way to compare all the changes between this standard and its previous edition. The Redline version is not an official IEC Standard, only the current version of the standard is to be considered the official document.

IEC 60331-3:2018 specifies the test method for cables which are required to maintain circuit integrity when tested in a metal enclosure and when subject to fire and mechanical shock under specified conditions. This document is applicable to cables of rated voltage not exceeding 600 V/1 000 V, including those of rated voltage below 80 V, metallic data and telecom cables and optical fibre cables. It is intended for use when testing cables not greater than 20 mm overall diameter. This document includes details for the specific point of failure, continuity checking arrangement, test sample, test procedure and test report relevant to electric power and control cables with rated voltage up to and including 600 V/1 000 V. Details for the specific point of failure, continuity checking arrangement, test sample, test procedure and test report relevant to metallic data and telecom cables and optical fibre cables are not given by IEC 60331-3. Although the scope is restricted to cables with rated voltage up to and including 0,6/1,0 kV, the procedure can be used, with the agreement of the manufacturer and the purchaser, for cables with rated voltage up to and including 1,8/3 (3,3) kV, provided that suitable fuses are used. It is not assumed that cables successfully assessed by this method, will also pass requirements for either IEC 60331-1 or IEC 60331-2. Testing to either of these two standards is to be carried out separately. Such additional performance can be recognised by the marking in accordance with IEC 60331-1:2018 Clause 11 or IEC 60331 2:2018 Clause 11. This second edition cancels and replaces the first edition published in 2009. It constitutes a technical revision. The significant technical changes with respect to the previous edition are as follows:
– extension of the scope to include metallic data and telecom cables and optical fibre cables, although details for the specific point of failure, continuity checking arrangement, test sample, test procedure and test report relevant to metallic data and telecom cables and optical fibre cables are not given by IEC 60331-3;
– improved description of the test environment;
– mandatory use of mass flow meter/controllers as the means of controlling accurately the input flow rates of fuel and air to the burner;
– improved description of the information to be included in the test report.
