Scope

This Part applies to electromechanical elementary relays (non-specified time all
or-nothing relays) for incorporation. It defines the basic safety-related and
functional requirements for applications in all areas of electrical engineering or
electronics, such as.
• general industrial equipment,
• electrical facilities,
• electrical machines,
• electrical appliances for household and similar use,
• information technology and business equipment,
• building automation equipment,
• automation equipment,
• electrical installation equipment,
• medical equipment,
• control equipment,
• telecommunications,
• vehicles,
• transportation,
• etc.
Compliance with the requirements of this Standard is verified by the type tests
indicated.
In case the application of a relay determines additional requirements exceeding
those specified in this Standard, the relay should be assessed in line with this
application in accordance with the relevant IEC standard(s) (for example IEC
60730-1.1999, IEC 60335-1.1991, IEC 60950-1.2001).

Summary	This standard applies to basic electromechanical relays, provides electrical or electronic engineering fields based electromechanical relays with basic safety requirements and functional requirements. These application areas such as: General Industrial Equipment, electrical facilities, electrical machinery, household and similar electrical appliances, IT and business equipment, building automation equipment, automation equipment, electrical installation equipment, medical equipment, control equipment, telecommunications equipment, aerospace carry tools, transportation, other equipment. This standard requires compliance by the specified type tests into a new line verification. If the relay purposes beyond the scope of this standard specifies requirements increase, the relay should be based on use by pressing the corresponding IEC standards to be assessed.
