Foreword
This amendment to HD 604 S1:1994 has been prepared by WG 10 of CENELEC TC 20 'Electric Cables'. CENELEC TC 20 confirmed at its Athens meeting (November 1995) that the amendment should go to the Unique Acceptance Procedure.
As well as the listed additions and amendments to the particular sections of Parts 3-5, the title and scope of the HD have been amended in order to accomodate cables rated 1,973,3 kV, which had temporarily been included in HD 622 S1.
NOTE: During the preparation of this amendment, HD 505 (Sections 1.1 to 4.1 inclusive! has been replaced by EN 60811 (Sections 1-1 to 4-1 inclusive).
In general the updating of these references has not been included in this amendment unless a complete section has been introduced or replaced, but users should refer to EN 60811 for the most up-to-date information. The clause numbers for the test methods in EN 60811 are identical to those in HD 505.
The draft was submitted to the Unique Acceptance Procedure in March 1996 and was approved by CENELEC as amendment A1 to HD 604 S1:1994 on 1996-12-09. By decision of the Technical Board (D81/139) this HD exists only in English and French.
The following dates were fixed:
- latest date by which the existence of the amendment has to be announced at national level (doa) 1997-06-01 - latest date by which the amendment has to be implemented at national level by publication of a harmonized
national standard or by endorsement (dop) 1997-12-01 - latest date by which the national standards conflicting with the amendment have to be withdrawn (dow) 1997-12-01

0.6/1,0 AND 1,9/3.3 kV CABLES WITH SPECIAL FIREPERFORMANCE FOR USE IN POWER STATIONS
Part 1 - General Requirements
1 ■? General
1.1 Scope
HD 604 applies to rigid and flexible conductor cables for fixed installations having a rated voltage Uo/U of 0.6/1 kV or 1.9/3.3kV. The insulation and sheaths may be either thermoplastic or thermosetting, halogenated or halogen free. The cables are mainly intended for use in power generating plants and sub-stations. All cables have specific fire performance requirements. Cables designed to be installed within the containment area of nuclear power plants (LOCA cables), or cables specifically designed to be radiation resistant are not included in this HD.
Control cables having a minimum conductor size of 1mm* up to 61 cores are included in addition to the range of power supply cables.
This Part 1 specifies the General Requirements applicable to these cables; additional or deviating requirements are given in the particular sections of this HD.
Test Methods are specified in EN 60811, HD 21, HD 22, HD 383, HD 405, HD 602, HD 605, HD 606 and IEC 96-1
The particular types of cables are specified in Parts 3, 4 and 5.
1 2 Object
The objects of this Harmonisation Document are:
- to standardise cables that are safe and reliable when properly used, in relation to the technical requirements of the system of which they form a part;
- to state the characteristics and manufacturing requirements directly or indirectly bearing on safety,
- and to specify methods for checking conformity with those requirements.
