Overview

The Occupational Safety and Health Administration (OSHA) was established as part of a system to protect the public from products used in the United States. Initially, OSHA entrusted two institutions to carry out safety-related testing and certifications. However, with the growth of the US economy and its industry, the workload dealing with occupational safety and health-related issues skyrocketed, leading to greater demand for various improvements. Accordingly, pursuant to Article 29, Paragraph 1910.7 of the US Federal Regulations (CFR), OSHA expanded the list of Nationally Recognized Testing Laboratories (NRTLs) to include 17 domestic and international institutions in 1998.
