 Dental magnetic attachment was approved by International Standard (ISO 13017). This allowed to guarantee performance and safety of dental magnetic attachments, and to secure reliability as medical equipment by eliminating poor-quality products in the world. The details of attractive force measuring method of magnetic attachments were mentioned in the ISO written standards.
 The present study investigated if attractive force of a magnetic attachment can be accurately measured by different measurers based on the attractive force measuring method specified in the written standards to evaluate the need for revising the written standards.
 The result showed that each measurer obtained accurate attractive force measurement value of a magnetic attachment, suggesting that the description of the written standards was easy to understand.
