How to use Acceptable quality Level AQL

ACCEPTABLE QUALITY LEVEL

is the "most tolerable" level of the average over a period of batches. These tables are the United States standard equivalent in all national and international standardization organizations (ANSI / ASQC Z1.4, NF06-022, BS 6001, DIN 40080).

Basically, there are three types of defects that are often differentiated. For most of its restricted goods or products are: Critical l% 0 defect for critical defects is totally unacceptable: users may be harmed, or rules are not respected The major defect of 2.5% for major defects of this product is usually not considered to be acceptable to end-users The minor defect of 4.0% for small defects is some departure from specs, but most users do not mind The Acceptable Quality Limit, commonly referred to as an AQL, is a widely used method for measuring sample production orders to find out whether all product orders have met the client's specifications. Customers then have data to make informed decisions to accept or reject them. Your Inspection Report will clearly state whether your production has passed or failed on your preferred AQL. Note that this tool is used most during the final outbound inspection when the product is ready to be sent out and sometimes during production when the number of products is sufficient to have an idea of the average quality AQL Tables the AQL table is the buyer statistics tool (for product inspection). They are industry standards. Most of the suppliers involved in international trade are already familiar with it AQL / acceptable quality level They help determine the two main elements:- How many samples should be taken and checked, between a set of products or parts of the quantity order?- Where is the limit between acceptance and rejection, when it comes to defective products?

The need for objective quality measurement certain product categories, there will be products that are handicapped almost every production. Often true even after the manufacturer checks each individual product and repairs the damaged, since the visual inspection is not 100% reliable. Therefore, in many supplier / buyer relationships (especially when the application does not produce live or dead), suppliers are not expected to deliver flawed goods. The buyer needs to control the quality of the goods / products purchased, because he does not want too much of the defective item How to set a limit between acceptance and rejection in a way that can be agreed and measured?

What the AQL (ACCEPTABLE QUALITY LEVEL) How to determine the exact sample size and reception number? How to use the AQL table for correct checks for your needs. For production checks with 4,500 pcs with Acceptable Quality Limit II, Table A shows the general inspection level "L". Referring to Table B row L. For sample size 200, with AQL 2.5, no more than 10 units may fail for forwarded reports

Using the AQL tables, importers should be aware of the following three parameters:

The lot size – The number of items ordered is the lot size, and it is advised to perform separate inspections for each lot. If only one product was ordered, the lot size is the total batch quantity.

The inspection level – Three inspection levels dictate how many samples to inspect:

Level I – This is the least strict inspection level. It can be used if the importer has a lower tolerance for product quality issues, such as with lesser-value gifts that come free with a purchase. Or perhaps a supplier has passed all previous inspections, and the buyer feels confident in their product quality. It is important to understand that settling for a Level I inspection as a way to spend less time and money is a high-risk strategy.

Level II – Used by default, Level II is the most widely adopted.

Level III – The strictest inspection level, Level III dictates the largest sample size and is, therefore, most representative of the overall quality of the products. Buyers may opt for a Level III inspection for high-value products (example: luxury goods)The AQL level appropriate for your market – AQLs are highly flexible because they allow importers to customize the quality tolerance for their product. Importers usually set different AQLs for critical, major, and minor defects. Although standardized AQLs of 0% for critical defects, 2.5% for major defects, and 4% for minor defects are often used, a buyer might require stricter AQLs for high-value items or markets with higher consumer expectations. When the buyer specifies these particular AQLs, it is an indication that as long as the percentage of defective items in the lots supplied by a manufacturer is lower than the AQL, most of the shipment will be accepted.
