Cable tests that are not equivalent, and why
IEC 60754-1 / -2 ≠ NEC / UL / CSA
Not equivalent, because No North American listing tests the halogen acid gas of a cable: "LSZH" on a North American cable has no standard behind it unless the offer names a separate specification.
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)
- CPR a1 (EN 60754-2): conductivity under 2.5 µS/mm and pH over 4.3. Sources: EN 13501-6 draft (BSI FSH/21_11_0073, undated, before the published EN 13501-6:2014), Table 1 notes (2) to (7), p. 21 (read in a draft)
NEC / UL / CSA
- No halogen acid gas test in the NEC listings (VW-1, UL 1685, UL 1666, NFPA 262). A navy specification (MIL-DTL-24643) may have one; not checked here. Sources: research: equivalents map F3 (NEC listings read for halogen tests; MIL-DTL-24643 not checked) (quoted by others)
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 NEC / UL / CSA equivalent to IEC 60754-1 / -2?
No. No North American listing tests the halogen acid gas of a cable: "LSZH" on a North American cable has no standard behind it unless the offer names a separate specification.
