SPEARWERX Javelins have always been built to the highest standards and quality. The independent verification system for those standards is the IAAF certificate. In order to obtain this certificate, the javelins are thoroughly tested by the IAAF to verify all international rules and specifications are met. The IAAF standards are used for NCAA, USATF, AAU, and High School javelin requirements in the Unites States. IAAF is the gold standard and required for international competitions in Europe, Canada, and Australia.

Only a handful of javelin companies meet these requirements.
