Cable tests that are not equivalent, and why
IEC 60754-1 / -2 ≠ IS 10810-59
Not equivalent, because The Indian halogen-free limit sits at the method's own lower limit, so IS 10810-59 alone cannot show that a cable is halogen free.
IEC 60754-1 / -2
- Halogen acid gas of the burnt material; the product standard sets the limit, for example BS 6724: HCl at most 0.5 % per component. Sources: BS 6724:1997+A3:2008, Table 2, p. 10 (read in the standard)
- IEC 60754-2 recommends a weighted pH of at least 4.3 and a weighted conductivity of at most 10 µS/mm. Sources: IEC 60754-2:2011 (edition 2.0), Annex A p. 19 (recommended weighted pH and conductivity) (read in the standard)
IS 10810-59
- Based on IEC 754-1:1982. The method is not recommended below 5 mg/g (0.5 %), and 0.5 % is the very limit the Indian product standards set for halogen free (HCl + HBr under 0.5 %). Sources: IS 10810 (Part 59):1988, cl. 2, p. 1 and the explanatory note, p. 4 (read in the standard); IS 17048:2018, cl. 5.3, p. 4 (flammability), cl. 5.6, p. 4 (smoke), Annex A item 9, p. 19 (halogen) (read in the standard)
Values as the sources print them, every one with its source and how it was seen; where a value is not held, it says so. The cable's own standard and the specification decide which test applies.
Questions and answers
Is IS 10810-59 equivalent to IEC 60754-1 / -2?
No. The Indian halogen-free limit sits at the method's own lower limit, so IS 10810-59 alone cannot show that a cable is halogen free.
