Specifies requirements for the connection of appliances to the water mains to prevent backsiphonage of non-potable water into the water mains and flooding due to failure of hose-sets. Appliances include washing machines, dishwashers and other appliances. This includes domestic appliances and those in shops and communal flats. The water pressure is not to exceed 1 MPa. Connection may be temporary…

IEC 60958-1:2006 specifies the consumer application of the interface for the inter-connection of digital audio equipment defined in IEC 60958-1. This third edition of IEC 60958-3 cancels and replaces the second edition published in 2003 and constitutes a technical revision. It includes the following changes:<br /> - Electrical and optical requirements are removed from IEC 60958-3;<br /…

This part of IEC 61000-4 relates to the conducted immunity requirements of electrical and electronic equipment to electromagnetic disturbances coming from intended radio-frequency (RF) transmitters in the frequency range 9 kHz up to 80 MHz. Equipment not having at least one conducting cable (such as mains supply, signal line or earth connection) which can couple the equipment to the disturbing RF…

This standard applies to circuit-breakers, the main contacts of which are intended to be connected to circuits, the rated voltage of which does not exceed 1 000 V a.c. or 1 500 V d.c.; it also contains additional requirements for integrally fused circuit-breakers. It applies whatever the rated currents, the method of construction or the proposed applications of the circuit-breakers may be.

ISO 6149-4:2006 specifies dimensions and performance requirements for external hex and internal hex port plugs for use with ISO 6149-1 ports. Port plugs in accordance with this part of ISO 6149-4:2006 can be used at working pressures up to 63 MPa (630 bar). The permissible working pressure depends upon the plug end size, materials, design, working conditions, application, etc.

ISO 9974-4:2006 specifies dimensions and performance requirements for metric external hex and internal hex port plugs for use with ISO 9974-1 ports. Port plugs in accordance with ISO 9974-4:2006 can be used at working pressures up to 63 MPa (630 bar). The permissible working pressure depends upon the plug end size, materials, design, working conditions, application, etc.
