Are there testing and design standards for bike locks?

The two most common security ratings you`ll find on Bike Locks are the Sold Secure designation (Bronze, Silver, Gold, and Diamond), and the ART star rating (5 stars is the highest rating and sparingly bestowed upon locks).

Manufacturers may also include their own in-house security ratings to give buyers a sense of how much theft-deterrence they can expect from a specific lock. Such ratings do not necessarily adhere to any independent scale or rating.
