The fundamentally revised DIN 11 854:2015-09 “Fittings for Food and Pharmacy – Hose Connections made of Stainless Steel” was published in September 2015.
The NA 003-01-14-AA work committee ‘Fittings for the Food Industry’ of the DIN Standards Committee (NAA) – in which LINNEMANN GmbH participates – collaborated with the 104-02-01 AA work committee “Hose Fittings” to revise DIN 11854:1991-01.
The editorial and content-focussed revision has the following changes:
a) The scope has been revised
b) A section “Standard References” has been added
c) A section “Terms” has been added
The standard applies to hose fittings made of stainless steel in conjunction with hoses made of elastomers with and without plastic inner layer (liner), which are intended for the production of hose assemblies in accordance with DIN 26055-3. The hoses can be used in a temperature range between −30 °C and +100 °C and at an operating pressure of −0.8 bar (vacuum) to 10 bar. Hoses with liners made of polytetrafluorethylene (PTFE) and derivatives can be used for temperatures between −30 °C bis +140 °C. The standard is now available from DIN Deutsches Institut für Normung e.V.

The decided correction of the DIN 11851 fittings of stainless steel for food and chemicals – pipe screw connections for rolling and butt welding appeared with edition February 2013.
The DIN working committee "Fittings for the food industry" in the fittings standards committee - of which Linnemann is also a member – informs us that changes have been made in DIN 11851. It concerns the standards DIN 11851:1998-11, DIN 11887:1998-11 and DIN 11851:2011-04. For example, the title of a standard was changed, new steel types and the material HNBR were added and dimensions changed. The standard is immediately available from the DIN Deutsches Institut für Normung e.V.
New DIN 11867:2012-11 Elbows fpr piping systems, welding fittings in stainless steel for aseptic, chemical and pharmaceutical industry.
The DIN task force "Armatures for food industry" within the technical committee "Armatures" - where Linnemann participates - has revised the norm. Compared to the old edition of December 2005, the contents were revised technically and editorially. Thus e.g. ovality clarified, control measures adapted and acceptance criteria listed in ASME BPE included.
New DIN 11865:2012-02 Stainless steels fittings for aseptic, chemical and pharmaceutical industry – Tees, elbows and reducers for welding on.
The DIN task force "Armatures for food industry" within the technical committee "Armatures" - where Linnemann participates - has revised the norm.
Compared with the former edition, dtd. January 2003 the technical and editorial content was altered. E.g. the admeasurement for fittings of row C (Tables 3, 6 and 9) was adapted to ASME BPE. The norm is now available at DIN Deutsches Institut für Normung e.V. "Berlin".
New DIN 11851:2011-04 Stainless steel fittings for the food and chemical industry - Screw pipe connections for expanding and welding.
The committee „Armatures" - which Linnemann participates - has revised the norm. The old version of November 1998 has been technical and editorial rewrited. Also the norm DIN 11887 „Round thread connections" and blind flanges have been included in the new version. The norm is now available at DIN Deutsches Institut für Normung e.V. "Berlin".
