This international standard relates to the immunity requirements of equipment, only under operational conditions, to pulse magnetic disturbances mainly related to:

- industrial installations and power plants;
- medium voltage and high voltage sub-stations.

The applicability of this standard to equipment installed in different locations is determined by the presence of the phenomenon, as specified in clause 3.

This standard does not consider disturbances due to capacitive or inductive coupling in cables or other parts of the field installation.

Other IEC standards dealing with conducted disturbances cover these aspects.

The object of this standard is to establish a common and reproducible basis for evaluating the performance of electrical and electronic equipment for household, commercial and industrial applications when subjected to pulse magnetic fields.

The standard defines:

- recommended test levels;
- test equipment;
- test set-up;
- test procedure.

This part of CISPR 16 specifies the characteristics and performance of equipment for the measurement of radiated disturbances in the frequency range 9 kHz to 18 GHz. Specifications  for antennas and test sites are included. 

NOTE In accordance with IEC Guide 107, CISPR 16-1-4 is a basic EMC publication for use by product committees of the IEC. As stated in Guide 107, product committees are responsible for determining the  applicability of the EMC standard. CISPR and its sub-committees are prepared to cooperate with product committees in the evaluation of the value of particular EMC tests for specific products. 

The requirements of this publication apply at all frequencies and for all levels of radiated disturbances within the CISPR indicating range of the measuring equipment.
 
Methods of measurement are covered in Part 2-3, further information on radio disturbance is given in Part 3, and uncertainties, statistics and limit modelling are covered in Part 4 of CISPR 16.

1 Scope

This document gives the safety requirements and measures for stationary and displaceable combined woodworking machines, having at least two separately usable working units and with manual loading and unloading of the workpiece, hereinafter referred to as “machines”. The integrated working units can be of these types only:

— a sawing unit;
— a moulding unit;
— a planing unit.

The machines are designed to cut solid wood and material with similar physical characteristics to wood.

NOTE 1 For the definitions of stationary and displaceable machines, see ISO 19085-1:2017, 3.4 and 3.5.

This document deals with all significant hazards, hazardous situations and events as listed in Clause 4, relevant to the machines, when operated, adjusted and maintained as intended and under the conditions foreseen by the manufacturer including reasonably foreseeable misuse. Also, transport, assembly, dismantling, disabling and scrapping phases have been taken into account

NOTE 2 For relevant but not significant hazards, e.g. sharp edges of the machine frame, see ISO 12100:2010.

This document does apply to machines also equipped with the devices/additional working units listed in the Scopes of ISO 19085-5:2017, ISO 19085-6:2017, ISO 19085-7:2019 and ISO 19085-9:2019.

This document does not apply to:

a) machines incorporating only a planing unit and a mortising device;

NOTE 3 Such machines are dealt with in ISO 19085-7:2019.

b) combined machines incorporating a band saw unit;

c) machines with a mortising unit with a separate drive other than the planing unit drive;

d) machines intended for use in potentially explosive atmosphere;

e) machines manufactured before the date of its publication as an International Standard.

1DV Modify Clause 1 by adding the following to the first paragraph:

This Standard applies to combined woodworking machines that are intended to be installed and used in accordance with the National Electrical Code (NFPA 70) in the United States and the Canadian Electrical Code, Part I (CSA C22.1) in Canada.

In Canada, general requirements applicable to these machines are provided in CSA C22.2 No. 0.

1 Scope

This document gives the safety requirements and measures for stationary multi-blade rip sawing machines manually loaded and/or unloaded, hereinafter referred to as “machines”, designed to cut solid wood and material with similar physical characteristics to wood.

It deals with all significant hazards, hazardous situations and events as listed in Clause 4 relevant to machines, when operated, adjusted and maintained as intended and under the conditions foreseen by the manufacturer including reasonably foreseeable misuse. Also, transport, assembly, dismantling, disabling and scrapping phases are taken into account.

NOTE For relevant but not significant hazards, e.g. sharp edges of the machine frame, see ISO 12100:2010.

This document does not deal with specific hazards related to the combination of single machines with any other machine as part of a line.

It is not applicable to machines:

— with all saw blades spindles mounted below the workpiece support/level only;
— intended for use in potentially explosive atmosphere;
— manufactured prior to its publication.

1DV Modify Clause 1 by adding the following to the first paragraph:

This Standard applies to multi-blade rip sawing machines that are intended to be installed and used in accordance with the National Electrical Code (NFPA 70) in the United States and the Canadian Electrical Code, Part I (CSA C22.1) in Canada.

In Canada, general requirements applicable to these machines are provided in CSA C22.2 No. 0.
