This document contains Abdullah Al Mahfuj's profile and presentation on acceptance sampling and acceptable quality level (AQL) in the textile industry. It discusses key points such as: 1) Sampling is selecting a suitable sample to make inspection decisions about accepting or rejecting lots based on predetermined standards. Acceptance sampling uses sampling plans to judge quality levels. 2) AQL refers to the average percentage of defective items that will be accepted in a lot. There are six common AQL levels used in apparel manufacturing from 1.0% to 10%. 3) Defects are classified into four categories - critical, major, minor, and slight - each with a different acceptable percentage range.

5. SAMPLING
Sampling is the act, process, or technique of
selecting a suitable sample
Acceptance Sampling
 It is a decision making tools .
 defined as sampling inspection in which decisions are

after a process to judge to predetermined standards

6. What is AQL?
 AQL means Accepted Quality Level
 It is one of the most used terms in readymade
garments industry when it comes in consideration to
quality.
 most of the acceptance decisions of garment export
order shipments are made on the basis of AQL based
sampling plans.
 It is expressed in a percentage number of average
defective items

7. Types of AQL System Followed in
Apparel Industry
• There are total six types of acceptable quality level
(AQL) system followed in garment manufacturing
industry which are pointed out in the below:
 AQL-1.0%,
 AQL-1.5%,
 AQL-2.5%,
 AQL-4.0%,
 AQL-6.5%,
 AQL-10%.

8. The defects which are found during inspection are
mainly classified into four categories:
 Critical: Must be 100% accurate. There is no range.
 Major: Normally 2.5%
 Minor: Normally 4%
 Slight: Normally 6.5%

9. Sampling Plans
• Sampling Plans specify the lot size, sample
size, number of samples and
acceptance/rejection criteria. Sampling plans
