Friendship publishes sponge hardness on Chinese degree scales without a named laboratory standard. TTDNA stores each value exactly as published and never converts it to Shore A, Shore C or an ESN equivalent.
Colours are only listed when an ITTF covering entry verifies them. Red and black are never assumed.
