1.1 How to use this manual

This manual is intended as an addition to the product manual. With this manual qualified users are able to install, commission and maintain hoses suitable for food contact as mentioned on the front cover.

1.2 Original instructions

The original instructions for this manual have been written in English. Other language versions of this manual are a translation of the original instructions.

1.3 Objective of legislation on food contact materials

In general all goods brought to market within the EU must meet the applicable safety standards as laid down in various EU legislation. For machinery this is the Machine directive 2006/42/EC. It specifies that materials that come into contact with food are cleanable and do not affect the taste and smell of the food product. The requirements from this directive are met by applying the EHEDG guidelines and by complying to the European frame agreement, regulation (EC) No 1935/2004. The purpose of this regulation is to provide the basis for securing a high level of protection of human health and ensuring effective functioning of the internal market dealing with materials and articles intended to come into contact with food. The principal goal of the European Hygienic Engineering & Design Group (EHEDG) is similar but much more specific. It promotes safe food by improving hygienic engineering and design in all aspects of food manufacture. This is done by providing guidelines that ensure products and processes to be food safe.

Materials that can come into contact with food must be listed as safe and it must be proven that migration of material components remains within specified limits. For rubber articles the frame agreement refers to the local laws applicable. These materials meet the requirements of the Dutch and American food laws, Warenwet and FDA and the recommendations of the German federal institute for risk assessment BfR. The final product complies with:

• Warenwet, Regeling Verpakkingen en

Gebruiksartikelen, 2.2.1, Appendix A, Chapter 3 Rubber articles, category 3

• The Code of Federal Regulations Title 21,

Chapter 1, Part 177, Subpart C, Section

177.2600 of the FDA FDA 21CFR177.2600

• The Recommendations of the German Federal

Institute for Risk Assessment, BfR

Recommendation XXI, category 4. The Bredel pumps are EHEDG certified, Type EL Class 1: for cleaned in-place equipment.

1.4 Materials for food contact

1.4.1 Approved materials
