MIL,STD-461 Tests

Why is the MIL-STD-461 Test is Necessary

Ege Test Center and MIL-STD-461 Testing

The MIL-STD-461 standard, which we test as the Ege Test Center, is required for the activities of the Ministry of Defense (DoD) and the requirements for the control of electromagnetic interference (EMI) emissions and sensitivity characteristics of electronic, electrical and electromechanical equipment and subsystems designed or supplied for use by their agents. The MIL-STD-461 standard is the basic standard for military electromagnetic compatibility testing at the device and subsystem level.

Measurement Forms;

Dissemination through conductivity (CE-Conducted Emission)
Susceptibility through conductivity (CS-Conducted Susceptibility):
Since the MIL-STD-461 is developed for use on all platforms and different platforms have different needs, all tests specified in the standard are not applied to all platforms.

For example;

Test CodeDescription
CE101Conductivity Transduction, Power Lines, 30 Hz – 10 kHz
CE102Conductivity Transduction, Power Lines, 10 kHz – 10 MHz
CE106Conductivity Transmission, Antenna Terminal, 10 kHz – 40 GHz
CS101Conductivity Throughput, Power Lines, 30 Hz to 150 kHz
CS103Sensitivity through Conductivity, Antenna Input, Intermodulation, 15 kHz – 10 GHz
CS104Sensitivity through conductivity, antenna input, suppression of unwanted signals, 30 Hz – 20 GHz
CS105Sensitivity through Conductivity, Antenna Input, Cross-Modulation, 30 Hz – 20 GHz
CS106Conductivity through Transition, Transitions, Power Lines
CS109Sensitivity through conductivity, construction current, 60 Hz – 100 kHz
CS11414 Conductivity through Cable Conductivity, Cable Injection, 10 kHz to 200 MHz
CS115Sensitivity through Conductivity, Cable Injection, Impact
CS116Sensitivity through conductivity, suppressed sinusoidal transitions, cables and power lines, 10 kHz to 100 MHz
RE101Radiation Transmission, Magnetic Field, 30 Hz – 100 kHz
RE102Radiation Transmission, Electric Field, 10 kHz – 18 GHz
RE103Radiation Transmission, Antenna Harmonic Outputs, 10 kHz – 40 GHz
RS101Fluorescence Through Radiation, Magnetic Field, 30 Hz – 100 kHz
RS103Fluorescence Through Radiation, Electric Field, 2 MHz – 40 GHz
RS105Temporality through Radiation, Temporary Electromagnetic Field

For example, the CE101 test is applied to the devices to be used in aircraft, submarine and ground forces,
but not to the devices to be used in aircraft connected to air forces. The CE102 test, on the other hand, is a test for all platforms. Although the standard on which the test is to
be applied to which platforms are defined, the conditions specified in the standard may not be met or the tests not required by the standard may be requested by the customer and the testing needs are only hard to follow from the standard. Therefore, starting from the start of the project test planning and preparation of a Test Plan document is very useful.

Why the MIL-STD-461 Test is necessary?

Thanks to the knowledge and experience of the Egetest Center expert teams for MIL-STD-461, you will be able to sell your product to the European market without any problem.

What is Radiated Emission test?

Important of Radiated Emission Testing

Ege Test Center and Radiated Emission Test

Radiated Emission , in other words, by means of Radiated Propagation is only one of the Electromagnetic Compatibility (EMC) tests. According to the product to be tested according to the EMC standard is determined after determining an anechoic chamber (anechoic chamber) or in the open field test area (OATS) is a test must be done. The purpose of the Radiated Emission test is to determine whether the unwanted electromagnetic frequencies of the product are below a certain level. Radiated EmissionIf the measurement results of a product being tested are below the limit values ​​specified in the relevant standard, this test is considered to have passed. If the measurements on the limit are obtained, a change in design or EMC is required on the remaining product. The studies carried out on this kind of product are R & D studies and are very important works for the producer.

What You Need to Know About Radiated Emission Test

The measured frequency range of the Radiated Emission tests usually starts at 30 MHz and can be up to 1GHz, 2GHz or 6GHz depending on the product specification and the applied standard. Measurements are made with the antennas designed for the specified frequencies and the measurement devices called the EMI Receiver. The measuring distance between the product and the antenna is usually 3 meters or 10 meters. It is also possible to change the limits according to the measuring distance. For example, the limit value of 40 dBuV / m at 3 m can be reduced to 30 dBuV / m if the measurement is done at 10 m.

The Radiated Emission test is one of the most basic tests of EMC tests, so it is a test that the product designers should be familiar with. Measures related to EMC testing of a product should start at the design stage of the product and continue during the serial production phase. Even when the product is in the end user, it should be followed.

Ce Certification

What are the requirements for automotive parts and components to be allowed in the European market?

In Europe, the quality of your products is often measured by meeting specific requirements. Failure to fulfill or fail to meet these requirements will or will disrupt your attempts to find buyers in the European market.

1.  Requirements to meet

Type approval – Compliance with technical standards for motor vehicles

All Vehicle Type Approval  (WVTA) is a certificate for various types and types of motor vehicles. EU legislation has introduced strict conditions for the harmonization of technical, safety and environmental standards among EU Member States (vehicles) and for agricultural and forestry tractors.

This type of approval or certification is valid in all EU Member States and is necessary when you wish to sell your products in the EU. Many automotive components have not been approved until final assembly. In these cases, it is not necessary to certify individual components; however, these components will have to comply with the type-approval requirements.

In 2017 the testing process will change. In addition to the current laboratory emissions and fuel consumption tests (  New European Driving Cycle  ), a  Real Driving Emission  (RDE) test will be performed. Europe is also   contributing to the development of a new global testing system called the World Wide Harmonized Light Vehicle Testing Procedure (WLTP).

Tips:

  • The Original Equipment Manufacturer and / or the approval authority determine the specific requirements that you must fulfill. These requirements vary widely per product and per market. This means that you may need to meet different requirements for different buyers and countries you export. Check the  specific type approval requirements of the receiver or approval authority for the parts you produce  .
  • An important requirement of the type approval certificate is the Production Eligibility (COP). COP, in conformity with the specification, performance and marking requirements in the product type validation legislation, refers to the ability to be produced in series which does not require another test. Make sure you have a suitable quality management system in place (see also dan Partner buyer requirements management section).

CE marking

Electronic equipment must be CE marked for marketing in the EU. The CE marking indicates that a product is assessed before it is placed on the market and meets EU safety, health and environmental protection requirements. The CE marking is sometimes also considered a means of conformity to the type-approval requirements; For example, electronic components requiring type approval and also electromagnetic compatibility (EMC) or CE marking for low-voltage equipment.

Tips:

  •  Learn more about the type approval in the EU Export Help Desk  .
  •  Learn more about the CE marking of electrical equipment in the EU Export Help Desk  .
  •  Follow step-by-step guidance in CE marking  .
  • If you are an electronics or electrical engineering manufacturer in the automotive industry   take a look at our work on these issues .

chemicals

To prevent environmental damage, the EU has restricted the use of certain chemicals in certain Regulations and Directives.

Tips:

  • In most cases, it is your EU buyer who is responsible for complying with the legislation on chemicals. Share information with your buyer regarding the substances used in your product, thus proving that it complies with all relevant legislation.
  • Ask your buyer about the chemicals policies and their expectations. Sometimes these directions are called ”black / gray“ lists. Does it provide a list of items you cannot use or would you like to receive information about the substances you use in a certain way? If you don’t yet know your buyer, try looking at a chemicals policy for a car brand. For example, ‘calling Volvo REACH.

What is IP Protection Degree and Class?

What are IP Protection and Degrees?

Degree of IP Protection The degrees used to measure the resistance of mechanical or electrical devices to water, dust or external impacts. The main purpose of the code is to provide detailed information about the marketed product. Ege Test Center provides you with detailed information on these scopes and expert IPs . For information and support, you can send an email to marketing@egetestcenter.com or contact us by filling out the form at https://en.egetestcenter.com/applyonline/ .

Examples of IP Protection standards

The main standards of IP Protection are in many different scopes such as EN 60529 , EN 60335 , EN 60598 . To the EN 60529 Standard, the classification of the degree of protection provided by enclosures for electrical equipment not exceeding 72.5 kV .

IP The degree of protection is determined as in the example;

IP 5 8 = First Household – Solids Class

IP5 8 = Second Household – Liquid Grade

You can use the following table to determine the strength class for your product:
