What Is AQL Inspection?

AQL refers to the ACCEPTABLE QUALITY LIMIT. In QUALITY control, AQL refers to the number of DEFECTIVE PRODUCTS. 

Usually, we calculate it in percentages. If a client asks for 2.5 AQL, it simply MEANS: 

The final number of items must not contain DEFECTS more than 2.5 percent. 

You REGARD it the THRESHOLD of the defective UNITS. 

What Are The Three Levels Of AQL General Inspection?

General INSPECTION comprises THREE different levels. Each level defines the PRODUCT quality and CHECKS the integrity. 

Let’s check them out! 

General Inspection Level I:

Acceptable Quality LEVEL I refers to the product inspections for LOW AMOUNT INVENTORY. 

• It defines the QUALITY of the product. 
• Sorts out the CRITICAL defects per Acceptable quality limit. 
• It is a GOOD choice when you already have worked with the SUPPLIER. The third-party inspectors will help you DETECT the major defects. 

General Inspection Level II:

General Inspection Level II is a DEFAULT level. If you APPOINT the inspector, it will be ACCEPTABLE QUALITY LIMIT II.

• It is good if you have GONE for the FIRST interaction with your SUPPLIER. 
• A fair amount of products is ENOUGH to check on this AQL level. 
• A thorough examination FILTERS out the products with MAJOR DEFECTS. 

General Inspection Level III:

How many UNITS do you have to INSPECT? 

Is the number of PRODUCTS high? 

If so, we have a ROCKSTAR! PRETTY affordable for HIGH quality with AQL limits. 

Inspection level III is PREFERABLE for a HIGH quantity of items. Level III needs large teams and deeper understanding. It may be time taking but if you have a skilled inspector, then it’s easy. Leelinesourcing has some of the most experienced inspectors in the industry. 

Here is what you SHOULD know about this. 

• It is a TIME-CONSUMING process. Because the inspectors check the AQL value in a large number of items. 
• You can CHOOSE it whether the SUPPLIER is new or OLD. 

Your INSPECTORS provide inspection results ASAP!

Sample SIZE is a BIGGER problem than you might think. 

If you have 1200 products, how do you even DETERMINE the sample size?

AQL charts describe the SAMPLE category. You don’t WASTE hours choosing the SAMPLES.

How Do You Select AQL Inspection Levels?

There are TWO levels of INSPECTION. 

It is a SPECIFIC situation in which you should use them. 

• The type of PRODUCTS 

Applying AQL to susceptible products? 

Set AQL as: 

• Critical defects to be zero percent. 
• The major defect ratio must be one or less. 
• The minor defect ratio should be 2-3 percent. 

Usually, the GENERAL INSPECTION level is GOOD. For high-end items, you can PREFER specific inspections. Share your specific targeted areas for High-End products. If it’s an electronic product, then be more precise about quality checks. 

• The batch size 

How many consumer products do you want? 

Batch size is QUITE crucial to help find the RELEVANT INSPECTION METHOD. 

For a smaller sample, choose GI. For large SAMPLE, consider AQL level GIII. 

• Market trends 

Depending on the market TRENDS, you can set the LOW value of your AQL. 

Focus on CUSTOMERS’ preference. Go and ROCK, then. 

How to Use the AQL Tables: Step-by-step Guide

ANSI ASQ Z1.4 AQL standard table acts as an AQL calculator. 

Here are FOUR STEPS to be the KING of it. 

Step 1: Choose INSPECTION TYPE and LEVEL 

Choose your INSPECTION type. Here are TWO KINGMAKER inspection types. 

• General Inspection level 
• Special inspection level

We already have a HIGHLIGHTED general INSPECTION level. Usually, sellers PREFER this option because it CHECKS generally. LEVEL II is the default option, but you can choose any specific option. You must be clear about your requirements and quantity level. Further sellers guide you a lot. 

When SPECIFIC products are checked, the inspection finds significant and MINOR defects. 

Step 2: Find sample size Code letters 

Sample SIZE code letters are QUITE CRUCIAL. THEY EVEN define the WHOLE table. 

So, it is ESSENTIAL to look at a SAMPLE size code letter and GO for your SPECIFIC type. 

AQL CHART has DIFFERENT columns. Check out the RELEVANT column in the AQL chart. 

For example, if you have 5 PRODUCTS. And you prefer the GENERAL INSPECTION level II. Check out the K under the INSPECTION column. Find the AQL sample size according to the given sample size code letter. Let’s suppose it is 1201-3200 in your TABLE. 

Step 3: Choose Acceptance Quality Limit for your product 

Once you have UNDERSTOOD the graph, it is NO LONGER a problem. 

Get your AQL sample size. Ask the INSPECTOR to check the number of PRODUCTS per the AQL sample size. 

Sampling inspections highlights: 

• Critical defects 
• Minor defects 
• Major defects 

A HIGH AQL means you allow a HIGHER percentage of defective products. A low AQL describes a low number of products with major or MINOR defects. 

Check your ACCEPTABLE quality limit as per your CHOICE. 

Step 4: Know ACCEPT and REJECT points

AQL sample size and INSPECTION give you the CHOICE to reject or accept the products. 

If products don’t QUALIFY AQL, you ask the supplier to reduce major or MINOR defects. It helps you to maintain the quality of your product. Share your concerns with the supplier deeply so he can fix them. 

Crucial things to understand about the AQL Chart 

Don’t know how to read the TWO TABLES on the AQL chart? 

Whether you are TESTING the first or SECOND table, here are some points you must know. 

Sampling Size 

Sampling SIZE is derivative of the GRAPH. 

For example, if you have 1000 watches. You can’t inspect the ENTIRE batch. Choose a MINIMUM number of products to CHECK. 

Define how many cartons you want to INSPECT. 

AQL charts help get AQL sample size. 

Inspection Types 

There are TWO FUNDAMENTAL inspection types. 

Each inspection TYPE has different LEVELS.  Understand which LEVEL you want and need to maintain quality. Choose accordion to your inventory size and quality standard requirements. 

Here are the inspection types. 

• General inspection. It has THREE levels. GI, GII, and GIII. 
• Special Inspection. It has FOUR levels. S1, S2, S3, and S4.

Lot Size 

LOT size defines the TOTAL number of products to be CHECKED for CRITICAL defects. 

The batch size COLUMN indicates the category you MUST follow. 

During the SAMPLING inspection, you must know the LOT SIZE. And get your SAMPLE size as per INSPECTION levels. 

Acceptable QUALITY limit 

Acceptable QUALITY limits define: 

• The product with critical defects. 
• Number of units with minor defects 
• The number of units with MAJOR DEFECTS. 

As per the CERTAIN function, you MUST know: 

• Acceptance number 
• AQL inspections 
• AQL standards. 

For AQL 2, the products are CONSIDERED acceptable whether they have defects in 2% or fewer units. Yet if the Defect is more than 2%, you could ask for a replacement. In most cases, they repair or change the defective items. Inspect them again before accepting the inventory.
