Statistical Quality Control Study: A Study Of Ebony Paints:- Okoli, Rita C.
ABSTRACT
The data was collected from monthly files
ofthe Quality control departmentofEbony Paints Industry. In this work, die
actual measured quality characterstics ofBone white speedy Emulsion and Bone
white speedy oil paint were considered January 1997 to August 1999. The
ultimate objective ofthe study was to construct control chart whih could be
used to study the production process ofthe quality characteristics ofthe two
types of paints. The statistical quality control technique used for this study
was process control (by control chart devices). The quality characteristics
investigated was the viscosity in Kp and the grade level in grammes per litre
ofthe two types of paints. For a more stable process variablity and mean, the
points that lie outside die warding and action limits were discarded and the
control limits were revised. At the end ofthe study, it was concluded that
Ebony Paints should not be rejected for its purpose. Thus, absolute rejection
oftheir product should r. be based on dieir standard not diis estimated
standard (control limits).
