To check if a helmet standard has been withdrawn, look up the standard by its number and name on the website of the organisation that publishes it, and check whether its status is listed as current, superseded, or withdrawn. A withdrawn standard is one that the publishing body no longer maintains, usually because it has been replaced by a newer version or a different standard. This guide explains, in general terms, what withdrawal means, why it happens, and how to check the status of a standard before you buy or keep using a helmet.
What Does It Mean When a Helmet Standard Is Withdrawn?
When a helmet standard is withdrawn, it means the organisation that published it has formally taken it out of use. The standard is no longer the one that manufacturers are expected to follow for new products, and it will not be updated or maintained. Helmets that were already made and certified to that standard do not suddenly become illegal or unusable overnight, but no new helmets should be certified to it after the withdrawal date.
Withdrawal is different from a standard simply being old. A standard can be old but still current if it has not been replaced, and manufacturers can still use it. A withdrawn standard, on the other hand, has been deliberately retired. The publishing body usually gives a reason, such as the standard being replaced by a newer edition, merged into another standard, or no longer matching current knowledge about helmet safety.
Why Are Helmet Standards Withdrawn or Replaced?
Helmet standards are withdrawn or replaced because knowledge about head injury and helmet design keeps changing. Researchers learn more about how impacts injure the brain, new materials become available, and testing equipment improves. When a standard no longer reflects that knowledge, the publishing body may write a new version with updated tests, and the old version is then withdrawn so that manufacturers work to the newer requirements.
Sometimes a standard is withdrawn because it has been merged with another one. Two overlapping standards for similar kinds of helmets might be combined into a single, clearer standard that covers both. In other cases, a standard for a very specific activity may be withdrawn because so few helmets are made for that activity that maintaining a separate standard is no longer practical, and those helmets are instead covered by a broader standard.

Where Can You Check Whether a Standard Is Still Current?
The most reliable place to check is the website of the organisation that publishes the standard. National and international standards bodies keep a catalogue of their standards, and each entry usually shows the standard’s number, its title, and its current status. A status of current means it is still in use, superseded means a newer version has replaced it, and withdrawn means it has been taken out of use altogether.
To use the catalogue, you need the standard’s full number, which is usually printed on the helmet’s label or in its paperwork. Search for that number on the publisher’s site rather than relying on a general web search, because general search results can mix up old and new versions and may show out-of-date information. If you are learning about how helmets handle different kinds of impact, reading about what MIPS is for helmets can help you understand one of the technologies used in modern helmet design.
What Should You Do If Your Helmet Was Made to a Withdrawn Standard?
If your helmet was made to a withdrawn standard, the first step is to check the helmet itself rather than panicking about the label. Look at its age, its condition, and whether it has been in a crash. A helmet that is old, damaged, or has taken a hard impact should be replaced in any case, whatever standard it was made to. A helmet that is in good condition and has not been crashed may still offer useful protection, even if its standard has been withdrawn.
The next step is to think about how the helmet is used. If it is a child’s helmet that will soon be outgrown, or a spare helmet that is rarely used, the withdrawal may matter less than it would for a helmet worn every day on a busy road. If the helmet is your main helmet for regular riding, it is worth considering a replacement that meets a current standard, because newer standards usually reflect newer testing and newer knowledge about head protection.
It is also worth checking whether the rules where you ride require a particular standard. In some places, the law or a sports club’s rules may specify which standards are accepted. If a withdrawn standard is no longer accepted where you ride, you may need a helmet that meets a current standard even if your old helmet is still in good shape. When in doubt, a local retailer or a cycling or riding club can often tell you which standards are currently accepted in your area.
How Can You Tell Which Standard Your Own Helmet Meets?
You can usually tell which standard your helmet meets by looking for a label or sticker inside the helmet, often under the liner or on the inside of the shell. The label should show the standard’s number and, in many cases, the name of the testing body that certified it. Some helmets also list the standard on a tag attached to the chin strap or in the paperwork that came in the box.
If the label has worn away or is hard to read, check the paperwork or the product page for the helmet model on the manufacturer’s website. Manufacturers usually list the standards their helmets meet, and the model name and size printed inside the helmet can help you find the right listing. Keep a note of the standard number once you find it, so you can check its status without having to take the helmet apart again.
Be careful with helmets bought second-hand or from an unknown seller, because the label may be missing or the helmet may be a copy. A genuine helmet should have a clear, readable label with a standard number you can look up. If there is no label at all, or the label looks poorly printed or inconsistent, treat the helmet with caution and consider replacing it with one from a trusted source. A helmet you cannot verify is a helmet you cannot trust.
Frequently Asked Questions
Q: Does a withdrawn standard mean my helmet is unsafe?
A: Not automatically. Withdrawal means the testing rules have moved on, not that your helmet has failed. Check the helmet’s age and condition, and consider replacing it with one that meets a current standard if it is old or heavily used.
Q: Can I still buy a helmet made to a withdrawn standard?
A: In general terms, new helmets should not be certified to a withdrawn standard, but old stock may still be on sale. Check the label and the standard’s status before you buy, and prefer a helmet that meets a standard that is still current.
Q: Where do I find the standard number on my helmet?
A: Look for a label or sticker inside the helmet, often under the liner or on the inside of the shell. The standard number is usually printed there, along with the name of the testing body, and it may also appear in the helmet’s paperwork.
