Local safety standards
Which Standard Should You Choose?
If you’re in Europe → Choose CE
If you’re in Australia/New Zealand → Choose AS/NZS
If you’re in North America → Choose CPSC
If you’re in Southeast Asia → Choose AS/NZS or CE
It's important to know the local laws that determine which safety standards apply in your country, and that you choose the correct version for your country.
