One of the major changes in the standard was that the contact discharge was the preferred test method not the air discharge method.
600801 The insulating support between the EUT and the earth reference plane is 10 cm thick. The fast-food restaurant company was not pleased and returned the all-plastic cash registers to the manufacturer. In the Beginning Electrostatic discharge ESD phenomena have been known since the Greek civilization was dominant thousands of years ago.
Establishes a common reference for evaluating 608801 performance of industrial-processus measurement and control instrumentation when subjected to electrostatic discharges. Summary Electrostatic discharge testing has evolved from a company-based reliability test in the s and s to a performance test on electronic products in the timeframe.
The s saw the release of the IBM-Personal Computer in which legitimized the Iwc market and it saw a movement of the computer industry and similar electronic industries medical equipment, laboratory equipment, etc. See Figure 5 of IEC for the illustration of the test set-up for table-top-mounted equipment, laboratory tests Figure 1.

Needless to say, the lab made that fact known while in parallel it developed an engineering fix to its product to allow it to pass 18 Kilovolts.
The amplitudes were quoted in both the negative and positive polarities. Search all products by. The international standards organizations got involved in the s with the release of IEC on ESD limits and test methods.
Therefore, it has been decided to retain the term ESD in the title. The EMC Engineers went back to work; they placed a metal ground plane under the all-plastic cash register and discharged to the metal ground plane now known as the HCP to simulate the 6081 experience.
IEC System of Conformity Assessment Schemes
The contact discharge was a more repeatable event than the air discharge method. Group iiecIEC Your basket is empty. Find Similar Items This product falls into the following categories.

This ensures that you are always up-to-date and saves you both time and money.
The EMC engineers very-cleverly developed an all-plastic cash register and the ESD gun would not discharge to the cash register, and, therefore, by definition the product passed the ESD test. This service is not available if you are a URL user where you do not log in with an email address.

Sorry, your blog cannot share posts by email. The output voltage was up to 8 kVolts for contact discharge and 15 kVolts for air discharge; both positive and negative. Most electronic companies in the s and s were aware of and concerned with ESD. A Van de Graaf generator, some high-voltage sources, and a green nylon carpet were all tried as potential ESD generators.
The s and s saw individual companies developing their own test values and test techniques. At that time, they had an air-discharge ESD gun which was used for their product development testing.
The emphasis has switched from the susceptibility of equipment to quoting how immune a product is to air-discharge and contact discharges from a portable ESD tester whose output is compliant with the latest international standard criteria. You need to log in before adding standards to the monitoring service.
Kangaroo Leather One computer company in the s began experimenting with ESD relative to its computers and computer peripherals. Webprint Printed and bound. A web subscription provides an easy and secure access to standards, and you are guaranteed to always have the latest edition. For further information, contact Dan at danhoolihanemc aol. The parameter of the ESD Generator stayed constant from the — standard; that is, the energy storage capacitor was pF, the discharge resistance was ohms, and the output voltage of 8 kV for contact discharge and 15 kV for air discharge.
Includes electrostatic discharges which may occur between electrostatically charged objects brought together near to the vital instrumentation.
They eventually came up with design fixes that allowed the all-plastic register to pass the ESD test. Start Webshop Product catalog Product presentation. Figure 2 Second Edition of IEC The second edition of IEC was released in and it cancelled and replaced the first edition published inits Amendment 1 and its Amendment 2 The polarity of the output voltages was both positive and negative. Immunity for residential, commercial and light-industrial environments.
