元素的防御和航空航天EMC测试

为满足我们国防和航空航天业客户的需求，Element在美国和英国的多个地点提供认可的MIL-STD-461和RTCA Do-160测试。我们的专家团队了解防御和航空航天电磁兼容性（EMC）测试的独特要求，并将与您合作，以提供您需要的测试。

关于EMC测试要求

EMC testing requirements are based on the environments of intended use. Because Defense and Aerospace products often need to operate in severe conditions, and are critical products in nature, thorough testing is essential. Due to the variability of the intended environment, susceptibility test levels and emissions limits will differ based on where the product is installed and used.

For military installations, different test levels and limits are specified for installations on ground-based equipment, aircraft, ships, and submarines. Additionally, there are distinct limits for installations or use above or below decks on ships, and inside or outside an aircraft.

For civil aircraft equipment, susceptibility test levels vary greatly based on the function of the equipment. Critical navigation equipment is subject to much more stringent levels than a coffee maker or entertainment system. Emissions limits are based primarily on the location of the equipment inside or outside the fuselage, relative to the antennas used for the communications and navigation systems.

国防和航空航天试验标准

MIL-STD-461
The EMC standard for military subsystems and equipment in the US is MIL-STD-461. Prior to MIL-STD-461, each branch of service had its own set of EMC requirements and tests. The original MIL-STD-461 was published in 1967 and the most recent edition is MIL-STD-461G, published in 2015. Although MIL-STD-461 is required for US military programs, it is also the de facto EMC standard for defense projects all around the world, with a few exceptions.

MIL-STD-461包括分为四个部分的多个测试方法：

• 进行排放量
• 进行易感性
• 辐射排放量
• Radiated susceptibility

AviONICS始终需要进行和辐射排放测试，但是任何易感性测试方法的适用性通常由设备的安装和目的的性质定义。通常，更重要的航空电子（通信，导航，飞行控制）将需要更多的测试在更高的水平。

RTCA DO-160
在美国的民用飞机（航空航空公司）和世界上大部分地区安装的设备的EMC标准是RTCA DO-160。

DO-160 was first published by RTCA in 1975, with the most recent edition being DO-160G, published in 2010. In Europe, the document is published as ED-14G, by EUROCAE, the sister organization to RTCA. Both documents are identical in all ways except the title.

DO-160与MIL-STD-461不同，包括温度，湿度，振动等环境测试以及电能质量和EMC测试。与MIL-STD-461一样，DO-160包括多种测试方法：

• 进行排放量
• 进行易感性
• 辐射排放量
• Radiated susceptibility

除了这些测试之外，DO-160还包括电力质量和直接影响闪电的要求，这些闪电是由不同标准的军事应用覆盖。每个兵役（陆军，空军或海军）的基于设备的应用有不同的所需测试方法清单。

元素EMC laboratory capabilities

无论您的计划是否适用于军队或民用飞机，在开始测试之前明确了解合规性所需的测试。元素的专家可以帮助您了解您需要执行哪些测试。

元素test laboratories can perform all the tests specified in DO-160 and MIL-STD-461. We offer a full suite of testing that includes:

MIL-STD-461

The importance of an approved test plan

创建测试计划是您可以进行测试的最有价值的准备。较大的军事或航空航天承包商要求您在测试之前批准您的测试计划，以确保您的产品将满足其要求。如果您已经进行了测试计划，我们的团队还可以审查您当前的计划，以确保您准备好进行测试。

How to make test prep easier

The sooner you consider testing, the easier testing will be. Element’s military and aeronautical test engineers are here to assist you, whether you need help creating or reviewing your test plan or preparing your products, so you have a better chance of passing testing the first time. Time is financially valuable when it comes to testing, so many of our customers find it beneficial to come in for pre-compliance scans.

预恭维扫描

预符合规范扫描是一个很好的工具，可以在最终测试期间对您的设备进行如何执行的感觉。通过我们的一个地点停止运行扫描，以便发现可能需要改进的区域。如果您在开发周期中发现，必要的修改是更简单，更容易制作的更简单和更实惠。
