Ever look through a playground equipment catalog and see logos that don’t have anything to do with this particular manufacturer? They’re usually on the inside of the front or the back cover. These are organizations and/or certifications regarding that manufacturer and their equipment. Here’s one that you’ll see on most catalogs:
The IPEMA (International Playground Equipment Manufacturers Association) provides third party product certification services for American and Canadian public play equipment and public surfacing materials in the US. Essentially, this is a voluntary organization that virtually all playground manufacturers belong to. I like to think of it as the “Chamber of Commerce” for the playground industry.
