People in cold climates were very familiar with the ESD effect in a low-relative humidity environment as was frequently experienced in indoor environments in the winter time. An engineer from the company who worked with the Australian customers, visited the EMC lab and discussed the issue with the EMC lab engineers.
See Figure 5 of IEC for the illustration of the test set-up for table-top-mounted equipment, laboratory tests Figure 1. You may experience issues viewing this site in Internet Explorer 9, 10 or Kangaroo Leather One computer company in the s began experimenting with ESD relative to its computers and computer peripherals.

Monitoring Standards monitoring is a free service designed for you who wish to be alerted of changes to or new editions of the standards required in your work. Establishes a common reference for evaluating the performance of 608011 measurement and control instrumentation when subjected to electrostatic discharges. One product made by the computer company had a wide distribution in Australia and it had ESD problems whereas deliveries to other countries had no ESD problems.

In the Beginning Electrostatic discharge ESD phenomena have been known since the Greek civilization was dominant thousands of years ago. The polarity of the output voltages was both positive and negative. 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 iwc experience.
Customers who bought this product also bought BS EN The standard carefully pointed out in a NOTE that: The amplitudes were quoted in both the negative and positive polarities. The discharge resistance was often taken as ohms; the resistance of the human finger. The test was an air-discharge test. As electronic components changed from electronic tubes to solid state electronics in the s, companies became concerned with damage to electronic components and interruption of normal operation of electronic equipment.
The output voltage was up to 8 kVolts for contact discharge and 15 kVolts for air discharge; both positive and negative. The grounding cable from the VCP and the HCP to the ground reference plane had kohm resistors located at each end of the cable.
The companies tended to have proprietary standards and test methods on ESD and were not interested in exchanging information with their competitors on ESD. Elektromagnetische Vertraeglichkeit von Mess- Steuer- und Regeleinrichtungen in der industriellen Prozesstechnik. 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 version shows a much larger horizontal coupling plane than the standard, a vertical coupling plane unmentioned ina ground reference plane on the floor, and grounding cables between the horizontal coupling plane and vertical coupling plane and the ground reference plane with kohm resistors on both ends of the grounding cables.

The requirement is for electronic products to operate successfully when subjected to ESD phenomena representing the real-world environment as simulated in an EMC laboratory. The development of the HCP started with a well-known cash-register company in the s. One computer company in the s began experimenting with ESD relative to its computers and computer peripherals.
In most cases, the companies started at a recommended 5 kilovolts amplitude; when the companies idc could all pass that level, the consultants would recommend volts amplitude and so on! The s and s saw individual companies developing their own test values and test techniques.

Therefore, it has been decided to retain the term ESD in the title. However, the term electrostatic discharge ESD is widely used in the technical world and in technical literature. Electromagnetic compatibility for industrial-process measurement and control equipment – Part 2:
