Hygiene and the 'cleanability' of equipment used in the production of food are paramount. The widespread use of stainless steel equipment in the food industry goes some way towards ensuring these criteria are met - but the assurances provided by stainless steel are only as good as the fabrication quality of the equipment.
Following a presentation at ASSDA's annual conference in 2003 on the quality of food fabrications, particularly in the dairy industry, it became apparent that fabrication specifications, if they existed, were often inadequate and inconsistent.
As a result, ASSDA launched a co-operative venture, working closely with many fabricators involved in the food industry, to create the “ASSDA Food Specification: Fabrication and Installation of Stainless Steel Process Plant and Equipment in the Food and Beverage Industries”.
The title may be complex, but the intention is simple: used in conjunction with ASSDA's Accredited Fabricator scheme, it will standardise fabrication practices in Australia and improve efficiency and reliability by raising the standard of quality delivered.
ASSDA's Food Code of Practice is not intended to replace accepted national and international standards. Instead, it reflects their requirements in the design and fabrication process specifically for food and beverage plant. The specification is intended as a step forward from the more generic advice offered by the well-known “Blue Book”, published by ASSDA's sister organisation NZSSDA.
The Food Spec supplements the purchaser's specification and contract, with the purchaser's performance criteria and the supplier's design being the default conditions. There are prescriptive sections, such as those relating to spacing for access or acceptable levels of heat tint. However, best practice is flagged with the expectation that a contrary decision must be well supported. The consistent theme throughout is the delivery of cleanable surfaces in a hygienic environment.
The specification can be broken into four sections:
1. Scope, definitions, interpretation, document hierarchy and supplier systems required;
2. Design requirements with both general rules and specific items for process equipment, process piping and other piping;
3. Fabrication requirements for:
- Overall necessities of grade, materials care, welding and finishing procedures;
- Process vessel fabrication, whether by the supplier or others;
- The handling, welding and finishing of process tubing at ambient or elevated pressures; and
- The fabrication of non-product contact pipework at low or high pressures.
4. Practicalities such as transport, installation, commissioning and insurance.
The specification includes two appendices that list relevant standards and a discussion on the pros and cons of autogenous and filler metal use in welding of tubing.
There is no doubt that ASSDA's Food Code of Practice fills a void in the food industry. It is now up to operators in the industry to use it to improve practices in both their own businesses and the industry as a whole.
Third edition (May 2015) now available for purchase from ASSDA.
'Code of Practice for the Fabrication of Stainless Steel Plant and Equipment', also known as the "Blue Book", is intended to assist industry achieve the quality, structural integrity and food safety requirements necessary for stainless steel plant and equipment.
The document is intended to form part of any tender or contract document for the fabrication of such items and provides guidance on the following code of practice topics:
- Information and requirements to be agreed and documented
- Quality Assurance
- General design requirements
- Specific design features for tanks, vessels and silos
- Placement and type of welds
- Contamination prevention
- Cutting and forming
- Finishing processes
- Transportation and installation
- Insulation and cladding
The 58-page publication is prepared by the New Zealand Stainless Steel Development Association and is available for sale through ASSDA.

ASSDA is excited to launch the fifth edition (2020) of the Stainless Steel Stock Guide. After an extensive process of review, we are proud to offer a resource aimed at disseminating an up-to-date breakdown of 'ex-stock' stainless steel materials on offer in Australia.
What is the ASSDA Stainless Steel Stock Guide?
It is an online-only publication which details the stocking (defined as stocked in Australia as regular item) portfolio of commonly-used stainless steel semi-finished and finished materials. Information has been provided to ASSDA by suppliers and is intended as a general indication of common availability only. Contents include:
- Sheet, Coil and Plate
- Safety Flooring Products
- Wire and Wire Rope
- Pipe and Tube
- Pipe and Tube Fittings
Australian suppliers have the capacity to tailor many products to individual specification, and special product runs can be arranged provided sufficient time is allowed.
If you are looking for a supplier, fabricator or other stainless steel service, ASSDA's Buyers' Guide is an excellent starting point. Available on the homepage, the ASSDA Buyers' Guide is a comprehensive industry director and reference to the stainless steel industry in Australia, designed to promote our industry and member capabilities.
Who is it for?
Anyone who needs or wants to know about stainless steel materials are readily available, and in what form and specification.
As a designer, specifier or engineer, use the Stainless Steel Stock Guide to better understand the relevant specification, sizes and product dimensions of readily available materials to aid project management and delivery.
As a fabricator or producer of stainless bearing goods, use it not only for your day-to-day procurement queries, but also to find ways to streamline operations, better manage inventories and optimise your own production processes.
Australian Stainless is ASSDA's flagship publication and is a leading industry magazine devoted to showcasing the unique diversity and durability of stainless steel.
