Query: Exploded before first ride

I've been riding bikes and installing tires for over 15 years now and this might be the worst tube I've tried. I had it on the rim, inside the tire, and at 33 PSI during the first fill up, it exploded in my hands (recommended PSI is 90). Took it off the wheel and it had split right down the seam of the tube. I bought a 2nd tube for the other wheel and it's inflated at around 50 PSI with no problems so far; might have been a lemon tube?
