Heaters usually have rubber sheathed (i.e SJ) cord, some types also simple SJT. Flat-irons still have cloth wrapped round cords, the single conductors are rubber sheathed. You hardly get the NISPT off the Rack here. You get 0.75 mm2 SPT1 and 0.75mm2 SJT w/o ground for these purposes.

The harmonised European cables have very long designations:

For example, H03VVF mean that it's Harmonised, 0.3 kV max, and has a round plastic sheat. H03VVH-2F is the flat two-conductor cable.

(The German NYM is called EKK in Sweden. The relabling doubles the price.)

"Harmonized" is one of the European Committees' favorite words, as anyone living in this part of the world will know!

The coding breaks down into seven categories.

Identification of designation:
H = Harmonized standards
A = Authorized national standards

Nominal voltage:
03 = 300/300V
05 = 300/500V
07 = 450/750V

Insulating materials:
V = PVC
R = Rubber
S = Silicone

Sheathing materials:
V = PVC
R = Rubber
N = Polychloroprene (PCP)
J = Glassfiber braid (GFB)
T = Textile braid
T2 = Textile braid with flame resistance

Special constructions:
H = Flat divisible cords (Figure-of-8)
H2 = Flat non-divisible cords
D5 = Central core (non-supported element)

Conductor form:
U = Solid wire
R = Stranded wire
K = Fine wire (for permanent installation)
F = Fine wire (for flexible cables)
H = Superfine wire
Y = Tinsel

Number of cores:
2 = 2 cores
3 = 3 cores, etc.

Notice that for this system to apply the first character has to be "H" for harmonized standard. It's curious that a supposed international standard then specifies that "A" can be used for varying "authorized national standards."

Wow!,
The mind boggles as to how far all these abbreviations can go.
Little wonder our Regulation Books are so thick these days, it's all the explanations,involved to decipher the codes.
What is your maximum temperature wire?,
where would this be used?
