IS 694 : 2010 : Polyvinyl Chloride Insulated Unsheathed--And Sheathed Cables/cords With Rigid And--Flexible Conductor For Rated Voltages--Up To And Including 450/750 V

Scope

This standard covers general requirements of single and multicore cables/cords with rigid as well as flexible annealed bare/tinned copper and aluminium conductor, insulated and sheathed (if any) with polyvinyl chloride (PVC) for rated voltages up to and including 450/750 V ac, 50 Hz used in electric power and lighting including cables for outdoor and low temperature use. These cables may be used on dc systems for rated voltages up to and including 1 500 V to earth. This standard also includes cables with fire performance category in FR (Flame retardant) and category FR-LSH (Flame retardant low smoke and halogen) with conductor temperature not exceeding 70°C or 85°C. These cables require to qualify and comply the testing as specified in the respective category.

NOTES

1 The term cord is used for the flexible cables up to 5 cores covering the sizes up to 2.5 mm².

2 For cables for outdoor use, the cables shall meet requirements of additional ageing test given in Table 1.

3 The cables covered in this standard are suitable for use on ac single or three phase (earthed or unearthed) systems for rated voltages UO/U up to and including 450 /750 V, 50 Hz. The cables may be used on dc system for rated voltages up to and including 1 500 V to earth.

4 The cables covered in this standard are suitable for use where the combination of ambient temperature and temperature rise due to load results in a continuous conductor temperature not exceeding 70°C or 85°C.

5 The following types of cables are not covered in this standard:

a) Telephone cables,

b) PVC data transmission cables,

c) Instrumentation cables,

d) PVC insulated screened communication cables (braid/wires/tapes), and

e) Flexible power cord other than PVC insulated.

6 The tests specified in Sections 1, 2 and 3 shall meet the requirements specified in IS 8130 for conductors, IS 5831 for PVC insulation and sheath and tested as per the test methods given in relevant parts of IS 10810 series.

7 This standard covers the following categories of cables:

Category Code Environment Description

01 Cables for indoor installation

02 Cables for outdoor installations

FR Flame retardant

FR-LSH Flame retardant low smoke and

halogen

8 This standard does not cover the requirements of flame retardance test for bunched cables.

9 The specification is divided into following 3 sections, namely:

Section 1 General requirements

Section 2 Single core cables/cords for fixed and flexible wiring

Section 3 Sheathed single and multicore cables/cords for fixed and flexible wiring
