关于LFGB中PE,PP(铬含量,钒含量,锆含量)的限值

PE(bfr III):
The finished products may contain max. 10 ppm chromium, max. 20 ppm vanadium and max. 100 ppm zirconium.

PP(bfr VII):
The finished products must contain no more than 10 ppm chromium, no more than 20 ppm vanadium, no more than 100 ppm zirconium and no more than 100 ppm hafnium.

总铬含量 (<10ppm)
总钒含量 (<20ppm)
总锆含量 (<100ppm)

是总量，PP除了(铬含量,钒含量,锆含量)，还有 100 ppm hafnium.
