Main Standards for Dot Peen QR Code
AS9132
AS9132 is a grading standard made for dot peen qr code marking in the aerospace field. This standard looks at the physical parts of dot peen codes. It checks things like dot size, dot center offset, and angle of distortion. These grading rules make sure each dot peen qr code is strong and easy to read.
AS9132 gives clear rules for dot peen qr code quality. Dot sizes must be between 65% and 105%. The dot center offset should not go over 20% from the perfect grid. The angle of distortion can be up to 6 degrees on the finder pattern.
| Criteria | AS9132 | Other Standards |
|---|---|---|
| Readability Benchmark | Known for good readability | Varies, often less detailed |
| Durability Requirements | Has detailed requirements | May not have all criteria |
| Evaluation Criteria | Dot size, center offset, angle | Often less specific |
ISO 16022 and ISO 15415
ISO 16022 and ISO 15415 are important standards for checking dot peen qr code quality. ISO 16022 gives the main rules for Data Matrix codes. ISO 15415 adds more grading steps. These standards use scanning to check symbol contrast, modulation, and fixed pattern damage.
| Quality Indicator | Description |
|---|---|
| Decode Grade | Shows if machines can read the dot peen qr code. |
| Symbol Contrast Grade | Measures the difference between light and dark spots. |
| Modulation Grade | Checks if the reflectance is even across the code. |
| Fixed Pattern Damage Grade | Looks at how easy it is to find and identify the symbol. |
| Scan Grade | Shows the overall quality of the dot peen qr code in the image. |
These standards expect a flat, shiny surface and use set lighting angles. They work well for printed codes but may not fit all dot peen codes.
ISO 29158
ISO 29158 is the most advanced grading standard for dot peen qr code marking. It works on curved surfaces and uses different lighting angles. This standard uses special methods to check cell contrast, cell modulation, fixed pattern damage, and minimum reflectance. ISO 29158 gives grades from Grade 4 (best) to Grade 0 (fail).
- ISO 29158 checks:
- Cell modulation
- Contrast
- Fixed pattern damage
- Axial non-conformity
ISO 29158 helps companies mark dot peen qr codes on metal, plastic, and more. Companies use this standard to make tracking and product ID better.

Why ISO 29158 Is Best for Dot Peen QR Code
Key Benefits
Many companies pick iso 29158 for grading dot peen QR codes. This standard works well on metal, plastic, and curved parts. Iso 29158 uses smart ways to check if codes are good. It looks at how codes work in real life, not just in labs. This helps factories and workshops a lot.
Iso 29158 checks many things in a QR code. The table below lists what iso 29158 checks and why it matters:
| Quality Parameter | Description |
|---|---|
| Cell Contrast (CC) | Checks how much brighter the lightest part is than the darkest part. |
| Cell Modulation (CM) | Looks at how much the brightness changes in the code. |
| Distributed Damage (DD) | Sees if there are problems in different parts of the code. |
| Minimum Reflectance (MR) | Makes sure the dark parts are dark enough. |
| Axial Non-Uniformity (ANU) | Checks if the symbol is stretched or squished. |
| Grid Non-uniformity (GNU) | Finds out if the code’s grid is not lined up right. |
| Decode (DEC) | Makes sure the code can be read by a scanner. |
Factories like iso 29158 because it gives grades from 0 to 4. A higher grade means the code is easier to scan and follow. Iso 29158 works with many lights and surfaces. This helps companies keep codes good, even if parts are rough or look different.
Note: Iso 29158 helps companies follow tough rules in car and airplane industries. It helps with tracking and keeping products safe.
Iso 29158 also helps teams spot problems early. Workers can fix code issues before products leave the factory. This saves time and money for everyone. Iso 29158 lets workers check codes fast, so work does not slow down.
Limitations of Other Standards
Other standards, like iso 15415 and AS9132, do not always work for dot peen QR codes. Iso 15415 is best for printed codes on flat, shiny things. It uses the same light and wants perfect marks. Many dot peen codes are on rough or curved parts. Iso 15415 may give low scores to good codes because it cannot change for these real-life things.
AS9132 looks at dot size and shape. It checks if dots are lined up and look right. This helps sometimes, but it does not check if a scanner can read the code. Iso 29158 checks both how the code looks and if it can be read.
Iso 29158 is special because it tests codes as they are in real factories. It does not need perfect parts or special lights. Iso 29158 gives fair grades to codes on many kinds of materials. This makes it the best choice for grading dot peen QR codes.
