The contact discharge was a more repeatable event than the air discharge method. Elektromagnetische Vertraeglichkeit von Mess- Steuer- und Regeleinrichtungen in der industriellen Prozesstechnik. 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. A common discharge value for early standards was volts. An engineer from the company who worked with the Australian customers, visited the EMC lab and discussed the issue with the EMC lab engineers.

The insulating support between the EUT and the earth reference plane is 10 cm thick. Stoerfestigkeit gegen die Entladung statischer Elektrizitaet. The values of the parameters of the discharge current had to be verified with a 1 GHz oscilloscope.

The all-plastic cash register went into production and out into the real-world with real customers. From the technical point of view, the more precise term for this phenomenon would be static electricity discharge.

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.

The companies tended to have proprietary standards and test methods on ESD and were not interested in exchanging information with their competitors on ESD. The output voltage was a positive voltage only!

The engineers took the Australian engineer into the controlled environment and asked him to shuffle his feet while connected to the electrostatic voltmeter. Ieec 1 ,00 excl.

The output voltage was up to 8 kVolts for contact discharge and 15 kVolts for air discharge; both positive and negative.

One computer company in the s began experimenting with ESD relative to its computers and computer peripherals. Please download Chrome or Firefox or view our browser tips. There were some companies that were using a contact discharge approach to ESD where the ESD ied was in physical metal to metal contact with the electronic equipment.

The grounding cable from the VCP and the HCP to the ground reference plane had kohm resistors located at each end of the cable. Click to learn more.

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.

For further information, contact Dan at danhoolihanemc aol. 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. The rise-time at 4 kilovolts had decreased to idc.

Webprint Printed and bound. 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 s and s Most electronic companies in the s and s were aware of and concerned with ESD.

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.

Further information on the IEC is available from www. 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. The development of the HCP started with a well-known cash-register company in the s.

They eventually came up with design fixes that allowed the all-plastic register to pass the ESD test. Customers who oec this product also bought BS EN This article is primarily addressing the interruption effects of ESD to packaged electronic equipment.

Applies to the susceptibility of industrial-process measurement and control instrumentatiion to electrostatic discharges generated by operators touching this instrumentation and to electrostatic discharges generated between objects in the proximity of this instrumentation and establishes severity levels and the required test procedures.
