GB/T 19216.31-2008Tests for electric or optical fibre cables under fire conditions -- Circuit integrity -- Part 31: Procedures and requirements for fire with shock -- Cables of rated voltage up to and including 0.6/1 kV (English PDF)

Foreword

GB/T 19216 "in electric cables under fire conditions - Circuit integrity" is divided into six sections.

--- Part 11. Test equipment --- flame temperature not lower than 750 °C \u200b\u200bseparately for the fire;

Applying an impact test apparatus --- flame temperature of not lower than 830 °C for fights;. --- Part 12

--- Part 21. Procedures and requirements --- rated voltage 0.6/1.0kV and below cable;

--- Part 23. Procedures and requirements --- data cable;

--- Part 25. Procedures and requirements --- fiber optic cable;

--- Part 31. for fire with shock - Test procedure and requirements --- rated voltage 0.6/1kV and below cable.

This section GB/T 19216 of Part 31.

This section identical with IEC 60331-31:2002 "cables under fire conditions - Circuit integrity - Part 31. applying for fights Plus the impact of the test procedures and requirements --- rated voltage 0.6/1kV and below cable "(in English).

For ease of use, this section made the following editorial changes.

--- This part name is amended as. "In the electric cables under fire conditions - Circuit integrity - Part 31. impulse applied for fights Hit test procedures and requirements --- rated voltage 0.6/1kV and below cable ";

1 Scope

This section GB/T 19216 specifies the rated voltage 0.6/1kV and below the need to maintain the integrity of the cable lines in specific conditions Fire and mechanical shock test procedures and performance requirements, and provides time for the fire. This section is intended for diameter greater than 20mm test cable.

This section provides sample preparation, continuity checking devices, electrical test procedures, methods of burning cables and mechanical shock generated Method, and provides the results of the assessment requirements.

This section applies to low-voltage power cables and control cables with a rated voltage.

NOTE. Although this section is limited to the scope of application of rated voltage 0.6/1kV and below the cables, but the manufacturer and the purchaser agrees, and is equipped with the appropriate fuse After the device, the procedure can also be used below the rated voltage of 3.3kV and cables.
