Flat Wire:
SPT: Stranded, Parallel, Thermoplastic
This is always followed by a -1, -2 or -3, signifying insulation thickness for different applications.
HPN:  Heater, Parallel, Neoprene
Required for heater-type application, such as irons, toasters, etc.

NOTE:  We can run some 20 AWG, but mostly we run 18, 16 and 14 AWG, 2 or 3 conductors.
P is always Parallel Wire (Flat).

Jacketed Wire:
S = Stranded (or Service Wire)
J =  Junior Service (300 Volt).  If no "J" is in the wire type, then it is a hard service (600 Volt).
T = Thermoplastic.  If no "T" is in the wire type, then it has a rubber jacket.
O = Oil-Resistant Compound
W = Weather-Resistant Compound
V = Vacuum - as in vacuum cleaner.  This is a small O.D. jacketed wire, very flexible and initially used for vacuum cleaners but now used on many different types of products.  Available only in 18 AWG.

Examples:
SV = Stranded Vacuum Rubber Jacketed (NO "T")
SJT = Stranded Junior Thermoplastic
SJTOW = Stranded Junior Thermoplastic, Oil and Weather resistant for UL and CSA.  

Miscellaneous requirements:
S.P. = Surface Printed
N.M. = Non-Migratory compound to prevent the wire color from bleeding under unusual circumstances.
VW-1 = Vertical Flame test (formerly FR-1)
60°C = Standard temperature rating (except HPN - 90°C
105°C = Electri-Cord's alternate rating (we normally don't stock 75°, 90°C)
IEC, ICC = International Color Code on the inner conductors (Blue, Brown, Green w/Yellow Stripe)
N.A. = North American Color Code on the inner conductors (Black, White, Green)
41/34 = Stranding - 41 strands of 34 AWG wire for each inner conductor
T.C. = Tinned Copper inner conductors
RIBBED = Outer jacket is striated with ribs
R/S or W/S = Red or White Stripe for visual polarity inspection on Flat wire
