That would be the Underwriters Laboratories, or UL.
A function generator creates electrical waveforms. The purpose is for developing and testing electric equipment.
The purpose is to ensure that products will not harm actual sentient beings before the product is used on one.
The purpose of electrical screening in testing electronic devices is to ensure that the devices meet specific performance standards and are free from defects before they are released for use. This process helps identify any potential issues with the electrical components of the device and ensures its reliability and functionality.

ASTM stands for American Society for Testing and Materials. It is an International Standards Organization which helps in creating and publishing voluntary consensus for a large variety of materials, products systems and services. The organization has its headquarters located in Pennsylvania.
Electromagnetic compatibility (EMC) testing is a way of checking if a product generates electromagnetic energy. This is important not only for one's health but also for the proper functioning of electrical equipment.

Kewtech produces testing equipment, such as: multifunction testers; leads and accessories; electrical testing; PAT testing; insulation and continuity; loop impedance; RCD testers; environmental meters; clamp meters; multimeters; and power quality analysis.
JAMS typically follows the holiday testing policies of the organization requesting the testing. It's best to check with the specific organization or JAMS office to confirm the testing requirements for the holidays.
The purpose of controlling the environment when testing a hypothesis is ultimately to get a reliable result to the study.
"Testing: The process consisting of all life cycle activities, both static and dynamic, concerned with planning, preparation and evaluation of software products and related work products to determine that they satisfy specified requirements, to demonstrate that they are fit for purpose and to detect defects."
You can do your own electrical testing but a lot of companies out source so they don't have to divert their employees to non-essential tasks. Legally the person just has to be competent. You can find a good break down of electrical tagging and testing regulations at Electrical Tagging Information.
