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. The companies tended to have proprietary standards and test methods on ESD and were not interested in exchanging information with their competitors on ESD.
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 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.

An engineer 608011 the 6080 who worked with the Australian customers, visited the EMC lab and discussed the issue with the EMC lab engineers.

Establishes a common reference for evaluating the performance of industrial-processus measurement and control instrumentation when subjected to electrostatic discharges.

The edition did have a requirement for discharging to the earth reference plane to simulate discharges to objects in the vicinity of the Equipment Under Test EUT. The second edition of IEC was released in and it cancelled 660801 replaced the first edition published jecits Amendment 1 and its Amendment 2 The key parameters of the ESD Generator remained constant at pF for the energy storage capacitor and the discharge resistance is ohms.
The test was an air-discharge test.

At that time, they had an air-discharge ESD gun which was used ie their product development testing. Accept and continue Learn more about the cookies we use and how to change your settings.

Take the smart route to manage medical device compliance. 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 kec and establishes severity levels and the required test procedures.

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 requirement is for electronic products to operate successfully when subjected to ESD phenomena representing the real-world environment as simulated in an EMC laboratory. Subscription – always available and updated A web subscription provides an easy and secure access to standards, and you are guaranteed to always have the latest edition.
The faster, easier way to work with standards. The s and s ic individual companies developing their own test values and test techniques. The s saw the release of the IBM-Personal Computer in which legitimized the PC market and it saw a movement of the computer industry and similar electronic industries medical equipment, laboratory equipment, etc.
A common discharge value for early standards was volts. Electromagnetic compatibility for industrial-process measurement and control equipment – Part 2: Click to learn more.
The s and s Most ieec companies in the s and s were aware of and concerned with ESD. The standard carefully pointed out in a NOTE that: The international standards organizations got involved in the s with the release of IEC on ESD limits and test methods.
