This law states that if you make a contract in California for work, or to sell or deliver products by weight or measure, the agreement must follow either common standards or the metric system as established by the contract terms.

This law states that any contract or legal document in California is perfectly valid, even if it uses metric measurements instead of the usual ones.

This law specifies the standards for weights and measures in California, stating that all state and county measuring standards must align with those certified by the National Institute of Standards and Technology. It includes standards provided by the U.S., those procured by the state, ones in the possession of county sealers, and those held by certified laboratories.

This law requires a department to store state measurement standards in a suitable or controlled environment to ensure their accuracy. These standards must be certified by the National Institute of Standards and Technology (NIST) or through other approved procedures to confirm that they are precise.

This law requires that the department use California's established standards to certify both similar and different standards. These certified standards serve as the official references for calibrating and approving measurement devices used by government bodies and businesses.

This law says that when a county in California requests it, the state will provide copies of the official weights and measures at the county's expense. These copies, or any that the county gets on their own, must be tested and approved to ensure they are accurate, and they will be stamped with a "C" to show this certification. The materials of these copies don’t have to be the same as the state's original standards, but they need to be acceptable to the state department.

This law requires a state department to certify and verify weights and measures standards used by industries, according to national standards, whenever requested. It also states the department will charge fees to cover the costs of this service. The collected fees go into a specific fund within the State Treasury to support the administration of these duties.

If a county worker responsible for measurements believes that a county measurement standard is wrong, they must inform the relevant department. Then, if needed, they should make sure the standard is tested, fixed, or swapped out.

This law states that if someone is on trial for not following the rules about weights and measures, any official copies of those standards from the state can be used as evidence in court. The court will initially accept these documents as true and accurate unless proven otherwise.

In California, the official standards for units of weight and measurement are those set by the National Institute of Standards and Technology (NIST). These standards must be used for all weighing and measuring tools and transactions.

This law allows a department to set rules for certifying labs to conduct measurements if the department's own equipment can't handle them or if it's financially necessary. Certified labs must pay the department for this certification. The secretary can revoke or suspend certifications for valid reasons and must follow specific regulations to do so. Any disputes over certification revocation or suspension follow a formal procedure. Measurements from these certified labs are considered solid evidence in legal terms.
