House Bill No. 1542 amends existing laws related to weights and measures in Oklahoma agriculture. The bill removes the requirement for the Director of the Bureau of Standards to send reference standards to the National Institute of Standards and Technology (NIST) for certification. Instead, it allows these standards to be sent to a qualified laboratory for certification. Additionally, the bill eliminates the requirement for weights and measures to be certified by NIST, permitting a qualified laboratory to perform this certification instead.

The amendments are reflected in two sections of the Oklahoma Statutes. In Section 14-2, the language specifying NIST is deleted and replaced with "a qualified laboratory," while Section 14-3 similarly removes references to NIST and introduces the term "a qualified laboratory" for certification purposes. The bill is set to take effect on November 1, 2025.
