scope:

GENERAL

The purpose this document is to provide systematic cargo measurement procedures for use primarily by cargo inspectors and to specify procedures directed at minimising cargo contamination and losses, in the absence of, or in conjunction with, specific client guidelines. The following document should be considered a summary of best practices used within the industry.

Where the term "measurement" is used in a general sense, it should be taken to include all aspects of cargo inspection including (but not limited to) tank inspection, sampling, laboratory analysis and testing and other superintending activities, as required by the inspector's principals.

The points at which cargo inspectors are required to make their measurements are described and definitions of the terms used throughout this document are provided in section 2. Whenever possible terms approved by API, EI and ISO/TC 28 have been adopted.

The document also considers the purpose of a cargo survey and summarises general responsibilities which cargo inspectors will be held to accept when they are appointed.

Safety matters and related responsibilities are defined and emphasis is placed on the need for cargo inspectors to be continually conscious that safety requirements take precedence over all other considerations.

The document describes the detailed procedures which inspectors are required to follow and provides references to the analytical test methods and calculations. Reference is made to alternative methods since the procedures recognise that within the industry opinions may vary regarding the use of test methods, especially where different methods may be specified by parties and contractors.
