A Cannabis Testing Laboratory (Type 8) license allows a laboratory, facility, or entity in the state California to offer or perform testing of cannabis goods. Testing laboratories must obtain and maintain ISO/IEC 17025 accreditation.
Testing laboratories may be issued a provisional license allowing them to operate while they obtain ISO/IEC 17025 accreditation, provided they meet all other licensure requirements. https://bcc.ca.gov/licensees/testing_labs.html
