Acceptable Quality Level in the garment (AQL)

Acceptable Quality Level in the garment (AQL)

In this article, garment merchandising will discuss acceptable quality level in the garment (AQL) and will know about the other options   to ensure the quality  of the product. AQL stands for an acceptable quality level. In the garment export industry, the term AQL is  widely  used.  Acceptable Quality Level is basically the percentage of faulty pieces that are accepted or putative by the buyer from the manufacturer.

In short, the least adequate quality level of the product is the other of the acceptable quality level. The acceptable quality level is always different  from buyer to buyer, product to product,and process to process . An acceptable      quality level is categorized in three diverse principles. The three categories of acceptable quality level are   critical faults, major faults, and minor Faults.

Most of the import manufacturers use these classifications of the acceptable quality level to set the maximum        number of faulty units, beyond which a lot will be rejected. Such   as manufactures of the product set a  level of quality that no more than 3.5 % faulty items in total, in the entire over quantity, on average  over   several productions runs with the supplier.

When the product is made on a sampling basis and ready to be shipped, then before  shipping, the product passes through the step of inspection. At the time of inspection,many quality level tools are used to check the recommended quality of the product.Sometime it  is tough to understand that the prevention of  quality  issues defects should not be measured through an acceptable quality level. The reason is trusting  on  final  inspections to find out any faulty products or quality problems will cause significant postponements in production. They will be a waste of time and investment.

It is virtually unbearable to abolish defective products. The faults in products arise in almost every lot and can appear even after producers have checked separate products since visual  examinations aren’t 100%  full proof.

Therefore,it’s significant to guarantee that your resources are up to the standard and qualitative for producing required  quality  products.If  your  resources/raw  materials  are  not   as per standard,  to  instigate  with, you’ll jeopardy undergoing major quality problems through the last stages of production.

Taking control over the quality of your resources or raw materials will decrease quality jeopardies by up to 75%.

The Process of Acceptable Quality Level

The acceptable quality level (AQL) is stated in a percentage, the number of average faulty pieces, and can be estimated employing the below given formula.

Average Faulty Pieces = (Number of Faulty pieces found through inspection / Total number of pieces Inspection) x 100

For customer possessions, faults, or defects that are found through random sampling or inspections are classified into four categories

(1) Critical Faults:There is no range, and critical faults are completely intolerable. Garment must be 100% accurate.

(2) Major Faults:The products would be recognized intolerable by end-users. Typically 2.5%

(3) Minor Faults:The product, to some extent, doesn’t meet specifications, but the end-user won’t mind it. Typically 4

(4) Insignificant Faults: The faults are only identifiable internally. Typically 6%.

Besides, the garment industry recognizes six sorts of tolerable quality level values, as designated underneath.

First: Acceptable Quality Level 1%

Second: Acceptable Quality Level 1.5

Third: Acceptable Quality Level 2.5%

Fourth: Acceptable Quality Level 4%

Fifth: Acceptable Quality Level 6.5%

Sixth: Acceptable Quality Level 10%

The acceptable quality level standard used through checks is the focus on the price and quality of the product.

Usually, a lesser figure acceptable or tolerable quality level standard (1%) is used for the higher valued and higher

excellence garments. In comparison, a higher figure standard (10%) is used for lower valued, lower excellence garments.

As per the standard of acceptable quality level, the AQL for a garment factory is 2.5% for major faults and 4 % for

minor faults.Moreover, critical faults generally necessitate a zero acceptance level, and any products that fail to meet

the customary acceptance quality level will undertake a 100% inspection.
