(Amendment)Information technology - Cabling installation -- Part 1: Installation specification and quality assurance
Information technology - Cabling installation -- Part 1: Installation specification and quality assurance
This European Standard specifies requirements for the following aspects of information technology cabling:
a) installation specification, quality assurance documentation and procedures;
b) documentation and administration; c) operation and maintenance. This European Standard is applicable to all types of information technology cabling including generic cabling systems designed in accordance with the EN 50173 series.
Safety (electrical safety and protection, optical power, fire, etc.) and electromagnetic compatibility (EMC) requirements are outside the scope of this European Standard and are covered by other standards and regulations. However, information given in this European Standard may be of assistance in meeting these standards and regulations.

Informacijska tehnologija - Polaganje kablov - 1. del: Specifikacija in zagotavljanje kakovosti - Dodatek A1
Ta evropski standard določa zahteve za naslednje vidike kablov za informacijsko tehnologijo:
a) specifikacijo polaganja, dokumentacijo in postopke za zagotavljanje kakovosti;
b) dokumentacije in administracijo; c) delovanje in vzdrževanje. Ta evropski standard velja za vse vrste kablov za informacijsko tehnologijo, vključno z rodovnimi kabelskimi sistemi, narejenimi v skladu s serijo EN 50173.
Varnostne zahteve (električna varnost in zaščita, optična moč, ogenj itd.) in zahteve elektromagnetne združljivosti (EMC) so zunaj področja tega evropskega standarda in so zajete z drugimi standardi in predpisi. Vendar so lahko informacije, podane v tem evropskem standardu, opora pri izpolnjevanju teh standardov in predpisov.

94 requirements of EN 60332-1-2 shall either be:
95 1) terminated inside the building, within 2 m (unless an alternative distance if specified by local regulations)
96 of the point of internal penetration of the external fire barrier (e.g. floor/ceiling/wall)
97 or
98 2) any length exceeding 2 m (unless an alternative distance if specified by local regulations) is installed
99 within trunking or conduit that is considered as a fire barrier in accordance with local fire regulations.

th
102 Replace 6 paragraph with:
103 Fire barriers should be designed to facilitate their refurbishment following cable installation. Cables passing
