"This document is intended as a guide to assist in the development of a specification for analysers and their associated support systems for enquiry purposes and the subsequent assessment of the bids presented by the prospective vendors. The intention is to cover the requirements for large systems rather than for the acquisition of individuai analysers. This document is not intended as a design specification in it's own right and design guidance has been deliberately omitted. It should be read in conjunction with EEMUA Publication No. 138 "" Design and installation of On-Line Analyser Systems"" which provides the design detail guidance necessary for inclusion in the specification. To simplify the specification and bid process it is desirable to have a standard format for both the enquiry documentation and the response from the analyser vendor. This document is intended to provide this framework. The section entitled 'Scope of Supply' lays out the headings and any relevant associated comments for the specification of a complete analyser system. Analyser systems are not all the same and individual requirements for total content will invariably differ. However this document is laid out such that individual sections can be selected or omitted as required. The recommended approach is to include all section headings and where relevant state as ""Not Applicable"" The section entitled 'Bid Technical Evaluation' covers procedures for bid assessment and gives suggested points against which bids should be anaiysed."
