The Immunity Standards

The immunity standards are intended to establish a basic level of protection for products that are susceptible to electromagnetic noise. Currently these standards are on a voluntary basis in both Australia and New Zealand, but manufacturers exporting to Europe need to abide by certain irnmunity standards. A comparison between the Australian and New Zealand standards and their international or European equivalents is given in table 2.

THE POWER OF THE EUROPEAN IMMUNITY REQUIREMENTS

• The strength of the European immunity standards is the fact that they cover almost all the spectral/energy environments a device is likely to encounter.
  
  
• This suite of standards makes the product virtually trouble-free once installed.
