Readers may or may not know the details of a lab report. You shouldn't assume that they know a test well enough to fill in the report's blanks or that they know anything about the actual lab. To help you describe your lab thoroughly, assume you're writing for a peer in your class, a student who knows what the instruments are, but who doesn't know any of the details of what you're doing. Or, assume you're writing for design engineers who will use your information on a design project. They may not be familiar with all the terms, but if you list the standards, they can research the information.
