T/PSC 1.1-2022 Ship ballast water monitoring method - Part 1: Live organisms ≥ 50 μm in size
Basic Information
Scope
Scope: This document specifies the instruments, reagents, and procedures for detecting live organisms greater than or equal to 50 μm in ship ballast water samples using direct counting methods, including sample detection, data recording and calculation, and quality assurance and control. This document is applicable to the detection of live organisms greater than or equal to 50 μm in ship ballast water. Main technical content: This standard uses a counting frame to count live organisms greater than or equal to 50 μm directly under a stereomicroscope. Through conversion of sampling volume and concentrated sample volume, the density of live organisms greater than or equal to 50 μm in the sample is calculated. The main technical content includes sample collection, sample detection, data recording and calculation, and quality assurance and control.
