A number of volunteers were organized and asked to shuffle their feet on the carpet in a controlled humidity environment while holding on to a scientific electrostatic voltmeter.

In most cases, the companies started at a recommended 5 kilovolts amplitude; when the companies products could all pass that level, the consultants would recommend volts amplitude and so on!
The edition did have a requirement for discharging to the earth reference plane to simulate discharges to objects in the vicinity of ic Equipment Under Test EUT.
The fast-food restaurant company was not pleased and returned the all-plastic cash registers to the manufacturer. After some discussions with the Australian native, it was discerned that he 608011 normal clothing on his body with the exception of his shoes which were made of kangaroo leather.
The grounding cable from the VCP and the HCP to the ground iev plane had kohm resistors located at each end of the cable. The amplitudes were quoted in both the negative and positive polarities. NOK 1 ,00 excl. 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.
Customers who bought this product also bought BS EN An engineer from the company who worked with the Australian customers, visited the EMC lab and discussed the issue with the EMC lab engineers.

With the inventions of the transistor in and the Integrated Circuit inand irc utilization of these major breakthroughs in the development of computers and other electronic devices, industry began to worry about and to design components and end-products that could survive the discharge of electrostatic discharges to chips, printed circuit boards, and final packaged-products.
Worldwide Standards We can source any standard from anywhere in the world. The faster, easier way to work with standards. 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.
One product made by the computer company had a wide distribution in Australia and it had ESD problems kec deliveries to other countries had no ESD problems.

The benefits of a subscription: One of the major ie in the standard was that the contact discharge was the preferred test method not the air discharge method. See Figure 5 of IEC for the illustration of the test set-up for table-top-mounted equipment, laboratory tests Figure 1.
Establishes a common reference for evaluating the performance of industrial-processus measurement and control instrumentation when subjected to electrostatic discharges.

Includes electrostatic discharges which may occur between electrostatically charged objects brought together near to the vital instrumentation. Search all products by. 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. From the technical point of view, the more precise term for this phenomenon would be static electricity discharge. Click to learn more.
Further information on the IEC is available from www. Group 09IEC Note — The Europeans put a 6 in front of the and the International Community followed suit in the timeframe. While they were developing the HCP, they realized the HCP could be turned on its side to represent a vertical metal file cabinet and they proceeded to design the cash register to pass that test also that HCP on its side is the present-day Vertical Coupling Plane VCP test.
BS EN 60801-2:1993, IEC 60801-2:1991
There were some companies that were using a contact discharge approach to ESD where the ESD tester was in physical metal to metal contact with the electronic equipment. A common discharge value for early standards was volts. 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 60810 for air discharge.
Webprint Printed and bound. Most electronic companies in the s and s were aware of and concerned with ESD. Menu Skip to content.
The rise-time at 4 kilovolts had decreased to 0. Find Similar Items This product falls into the following categories.
IEC has no responsibility for the placement and context in which the extracts and contents are reproduced by the author, nor is IEC in any way responsible for the other content or accuracy therein. 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 real-life experience.
The s and s Most electronic companies in the s and s were aware of and concerned with ESD. Electromagnetic compatibility for industrial-process measurement and control equipment – Part 2: 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.
The insulating support between the EUT and the earth reference plane is 10 cm thick. The test was an air-discharge test.
