Defects

Jun 16, 2017

A defect is an undesirable characteristic of a product. It is defined as a failure to conform to specifications or a unit of a product which contains one or more defects is called a defective.

Defects can be classified as follows:

  1. According to measurability:
    • Variable defect – a defect which can be measured directly by instruments giving dimensions of length, weight, height, thickness, concentration, volume, viscosity, pH or size particles.
    • Attribute defect – a defect which cannot be measured directly by instruments. It shows mainly the conformance or nonconformance of the material to specifications.
  2. According to seriousness or gravity:
    • Critical defect – a defect which may endanger life or property and may render the product non – functional.
    • Major defect – a defect which may affect the function of the object and therefore, may render the product useless.
    • Minor defect – a defect which does not endanger life or property nor will it affect the function but nevertheless remains a defect since it is outside the prescribed limits.
  3. According to nature:
    • Ocular defect - a defect that is visible.
    • Internal defect - a defect which is not seen although present.
    • c. Performance defect - a defect in function.

In cases of defects, a product recall is necessary to assure the integrity of the company. Product recalls have two classes.

    • Class I recall: a situation in which there is a reasonable probability that the use of or exposure to a violative product will cause serious adverse health consequences or death.
    • Class II recall: a situation in which use of or exposure to a violative product may cause temporary or medically reversible adverse health consequences or where the probability of serious adverse health consequences is remote.

Consequently, Esco Pharma’s focus on quality and timeliness is relentless. Continuous improvement is a mantra. Cross functional teams from Esco Pharma’s Production, R&D, Quality Assurance, Senior Management, are regularly assembled to review and implement areas for improvement.
