Expansion joints for the food and beverage industry
When installed in applications for the food and beverage industry, expansion joints come into contact withthe process media. In this context, the term food contact materials (FCM) is often applied to describe allmaterials and articles with which the media come into contact throughout their production, processing andstorage. The EagleBurgmann product portfolio covers a wide range of FCM expansion joints designed for
different applications within the food and beverage industry.

In principle, the KE-flex Nitrile 300 expansion joint has the same characteristics as
the KE-flex Nitrile 235 and 600 expansion
joints. The main difference is that the
Nitrile 300 is manufactured in white nitrile, which is a requirement in some foodprocessing plants.

Rubber expansion joints for high pressure
applications are designed in accordancewith Fluid Sealing Association guidelines
and Pressure Equipment Directive PED
2014/68/EU. They can be built in various
configurations (single or multiple-archrubber bellows, with full faced rubber
flanges or swivel metal flanges).

AX type metal expansion joints cover the
mid temperature and pressure range forgeneral process equipment and are designed
to accommodate axial movements. The
material of the bellows is typically 254 SMO
or SS 321.

Flanges are supplied in one piece or
split in sectors and in materials such ascarbon steel (1.0038/S235JRG2, 1.0570/
S355J2G3) or stainless steel (AISI 304L,AISI 316L). Other materials are available
upon request.

11Regulations in the food and beverageindustry
The food and beverage industry is regulated by several authorities depending on
the geographical market. There are several regulations in place for Food Contact
Materials (FCM) depending on which materials and articles come into direct andindirect contact with the processed media.

EC 1935/2004
Regulation EC 1935/2004 provides a set ofcommon rules with regard to the safety andinertness of materials or articles that comeinto contact with food, either directly or
indirectly. These materials and articles arereferred to as Food Contact Materials (FCM).
The framework is issued by the European
Parliament and is valid for products soldwithin the 28 EU member countries, Iceland,
Liechtenstein and Norway.
EC 1935/2004 regulates several types ofFood Contact Materials and articles, including rubbers. With regard to manufacturing
and supplying expansion joints made fromrubbers, the following articles are important
for the compliance with EC 1935/2004.

Water Regulations Advisory Scheme
The intention behind the Water Regulations
Advisory Scheme (WRAS) is to prevent
contamination of public water supplies. In
order to demonstrate that a product complies with the Water Supply (Water Fittings)
Regulations and Byelaws in Scotland,
WRAS provides an approval scheme as wellas processes and guidance. Products are
considered suitable if they pass appropriatematerial and mechanical regulatory performance tests, which include checking that
products won’t affect the taste or smellof drinking water and do not promote thegrowth of microorganisms.

12

Traceability
According to Articles 2 and 17 of
EC 1935/2004, traceability must be applied.
This means, it must be possible to trace orfollow a material or an article throughout allstages of manufacturing, processing anddistribution.

Good Manufacturing PracticeGood Manufacturing Practice (GMP) describes a set of rules issued by the US Foodand Drug Administration (FDA). In Europe,
Article 3 of EN 2023/2006 must be appliedwith regard to Good Manufacturing Practice.
These regulations stipulate that materials
shall be manufactured in compliance with
GMP so that under normal or foreseeableconditions of use, they do not transfer theirconstituents to food in quantities that could:(1) endanger human health, (2) bring about
unacceptable change in the composition of
the food or (3) bring about a deterioration in
the organoleptic characteristics hereof.

Declaration of compliance
Article 16 of EC 1935/2004 states that a
written declaration of compliance mustbe issued for all materials covered by thisregulation. It must declare that all materials
comply with rules applicable for them. Appropriate documentation shall be available todemonstrate compliance.

Food and Drug Administration(FDA)
Regulations for the US market are issued
by the US authority responsible for food anddrugs, the Food and Drug Administration(FDA). However, these regulations are also
widely used outside the US. CFR Title 21,
Subchapter B regulates direct and indirect
Food Contact Materials.

Direct food contact
CFR Title 21, Chapter 1, Subchapter B, Part
172.5 sets out general provisions for directfood contact and stipulates that GMP must
be applied (1). This means, the quantity ofthe substance added to the food must notexceed the reasonable amount required toaccomplish the intended physical, nutritiveor other technical effect in the food. (2) Any
substance intended for use in or on food has
an appropriate food grade and is preparedand handled as a food ingredient.

Indirect food additives - polymers
CFR Title 21, Chapter 1, Subchapter B, Part
177.1550 regulates which Perfluorocarbon/
polymer components may come into contact
with food surfaces (single or repeated) underwhich conditions.

Rubber articles intended
for repeated use

BfR

EagleBurgmann

The German federal institute for risk
evaluation (Bundesinstitut für Risikobewertung - BfR) issues recommendations
on the health assessment of FCM. These
recommendations are not legal norms. They
are much rather a representation of thecurrent state of the scientific and technicalknowledge regarding the conditions underwhich consumer goods made of high polymer
substances such as plastics, silicones aswell as natural and synthetic rubbers meetthe requirements of EC 1935/2004, Article 3.
BfR recommendations are mainly applied in
the European region and in areas that are notharmonized on an EU level.

The portfolio of EagleBurgmann includes
food and beverage grade products compliant
with EC 1935/2004, FDA regulations as wellas BfR recommendations. These provisions
and recommendations are implemented in
our processes:
Traceability in materials
Traceability in production

Migration testing by third party**
UV resistance testing according to
EN ISO 4892-3
Salt mist testing, severity level 3 according
to DIN EN 60068-2-52(EU) EN 10/2011
This regulation is under the frame ofEC 1935/2004 and contains specific regulations for plastic materials and articles intended to come into contact with food. It includes a positive list of chemicals which areallowed to be used in the production of thesematerials and articles and which are covered
by EN 10/2011. According to Article 9, plastic
layers in plastic materials and articles shallbe subject to restrictions with regard to (a)specific migration limits, (b) overall migration
limits, and (c) restrictions and specifications
defined in the regulation.

Experience that counts!
Customized solutions for food andbeverage applications
Throughout the years, EagleBurgmann has been a preferred supplier withregard to developing new solutions and solving problems in design and material
selection. Together with our customers, we pinpoint their challenges to findthe right expansion joint as well as the right design for their unique equipment.
These challenges are usually concerned with avoiding contamination caused by
the expansion joint and eliminating all possibilities of accumulation of media orcleaning agents.

Sanitary sealing solution for dampers
Challenge: a long-time OEM customer needed a sealing solution for the damperas the current solution left a potential risk of contaminating the media when
opening, closing and cleaning the damper house. When the damper is in closed
position, pressure is applied around the damper house ensuring sealing.
A vacuum keeps the expansion joint from interfering with the spade
when opening the damper. The spade shaft penetrates the expansion joint
through rubber bushings.

Solution: several options were discussed together with the customer. After
testing prototypes (up to 7 bar), a V-flange expansion joint made from reinforced
Nitrile, which would act as a gasket, was selected.
