BS EN 41003-2009 pdf download.Particular safety requirements for equipment to be connected to telecommunication networks and/or a cable distribution system.
This BS EN 41003 applies to equipment designed and intended to be connected as a terminal to a TELECOMMUMCATION NETWORK and/or a CABLE DISTRIBUTION SYSTEM termination. It does not apply to equipment covered by EN 60950-1 and EN 60065.
This European Standard specifies the safety requirements of the interface to the TELECOMMUNICATION NETWORK and/or the CABLE DISTRIBUTION SYSTEM only and it does not specify any other safety requirements.
It applies regardless of ownership or responsibility for installation or maintenance of the equipment, and regardless of the source of power.
This European Standard, in accordance with the ‘principles of safety’ given in the introduction of EN 60950-1, covers the requirements and compliance criteria under three headings.
• Protection of equipment USERS from hazards in the equipment. The USER is considered to be protected from hazards in the equipment if the equipment complies with a relevant safety standard, for example one of those listed in Annex A, but compliance with those standards is not part of this European Standard.
• Protection of SERVICE PERSONNEL working on a TELECOMMUNICATION NETWORK and/or a CABLE
DISTRIBUTION SYSTEM and other USERS of a TELECOMMUNICATION NETWORK and/or a CABLE
DISTRIBUTION SYSTEM, from hazardous conditions on a TELECOMMUNICATION NETWORK and/or a
CABLE DISTRIBUTION SYSTEM resulting from the connection of the equipment.
• Protection of equipment USERS from voltages on a TELECOMMUNICATION NETWORK and/or a CABLE DISTRIBUTION SYSTEM.
Requirements additional to those specified in this European Standard may be necessary for
• equipment intended for operation while exposed, for example, to extremes of temperature, to excessive dust, moisture, or vibration, to flammable gases. to corrosive or explosive atmospheres,
• electromedical applications with physical connections to the patient.
The requirements for the following items are not covered by this European Standard:
• functional reliability of equipment:
• communication facilities with remote supply using hazardous voltage:
• protection of equipment, TELECOMMUNICATION NETWORKS and/or CABLE DISTRIBUTION SYSTEMS from damage.

4 Safety requirements and compliance criteria
NOTE It Is assned that adequate measures according to ITU-T Recommendation K.11 have been taten to reduce the hke4ihood that the overvoltages presented to the equipment exceed 1.5 kV peak. In instalations wtiere oveivoltages presented to the equipment may exceed 1.5 kV peak, additional measures such as surge suppression may be necessary
