DAIRY UK CODES OF PRACTICE ON MILK TANKER DESIGN CONTENTS REGULATION 2 FOREWORD 2 1. VACUUM LOADING PRESSURE DISCHARGE RIGID MILK COLLECTION TANKER 3 2. ATMOSPHERIC PUMP LOADING / DISCHARGE RIGID / ARTICULATED MILK COLLECTION TANKER 3. APPROVED RELOAD / BULK TANKER 14 9 REGULATION All tanks must conform to current legislation for build and food hygiene specification for tanks for the transport of milk and milk products. BS 3441 (1995) Food Hygiene Regulation (Ec) No. 852/2004, No. 853/2004 Dairy Uk DTAS (Dairy Transport Assurance Scheme) FOREWORD This Code of Practice sets down the guide lines and the minimum requirements for the design and build of any Milk Tanker that will be used under the Dairy Transport Assurance Scheme (DTAS). This document is to be used in conjunction with the above legislative documents and is in no way a replacement or substitute on its own. The purpose of this document is to highlight the " " agreed between the major Milk Companies, Tank Manufacturers and Operators in the UK and is endorsed by the UK Trade body for the Dairy Industry namely "Dairy UK". It is agreed that this COP does not, and should not, restrict any future design or improvements. However, any changes out with the COP standard must be approved by Dairy UK before they are included into any build programme. All due consideration will be given to any proposed design changes with an agreement that they will not be unreasonably refused. It is the responsibility of all concerned in the design change to seek approval from Dairy UK as failure to do so could result in a breach of the DTAS document.
