There are three relevant or critical dimensions in the luer lock that must be met at .001 . These dimensions are length . at and . at . Before inserting the tubing into the luer lock the solvent will be applied and a curing of T minutes will be allowed. The required bond strength is P pounds when stretched. The extra-strong IV set has the same functionality capabilities and dimensions that a normal IV set has. Additionally it has a special strength and a special labeling indicating it to be extra strong. The DMR and the DHF are complete. Flow up process and design capabilities The injection molding process is statistically stable with a Cpk of and a Ppk of across the entire universe of possible combinations of process parameters worst-case conditions . All three critical dimensions were met including all those devices made under the worst-case conditions. At 99 reliability and 95 confidence a safety factor of 3 was obtained during a stress-strength test. Curing time is a design parameter that needs control in manufacturing. During the reliability test it was realized that the connection luer lock to tubing is stronger than the .
