This document deals with all significant hazards, hazardous situations and events relevant to derinding , skinning- and membrane removal machines, when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4).This document deals with the hazards which can arise during commissioning, operation, cleaning, use, maintenance and decommissioning of the machine.The machines described in this standard are used for derinding-, skinning- and membrane removal of meat and fish by cutting at a straight blade and/or cutting with circular blades. Feeding could be done manually or automatically.Using open derinding-, skinning- and membrane removal machines, the product is guided by hand towards the cutting device.With automatic derinding-, skinning and membrane removal machines the product is transported by an infeed conveyor against the cutting device. Product with a weight > 25 kg has to be processed by an automatic machine.Derinding-, skinning-, and membrane removal machines for domestic purposes, hand-guided machines and table-top machines are not covered by this standard.This document only applies to machines which are manufactured after the date of issue of this document.This document covers the following types of machines:a) open derinding machines (see Figure 1 and Figure 2) with infeed table and a distance h between the standing position and the surface of the infeed table from 800 mm to 1 050 mm. The cutting thickness shall be t = 5 mm;b) open skinning- and membrane removal machines (see Figure 1 and Figure 3) with infeed table and a distance h between the standing position and the surface of the infeed table from 800 mm to 1 050 mm. The cutting thickness shall be t = 0,5 mm.

This document is applicable to the selection of bolting for flanged joints on equipment subject to the Pressure Equipment Directive 2014/68/EU.It specifies standards and additional requirements for dimensions, material properties and technical conditions of delivery for bolting.NOTE 1 Washers are not within the scope of this document.The selection is based on commonly used bolting. It covers common temperature ranges of the general service of flanges.When selecting bolting according to this document, it is essential to take into account environmental conditions and other parameters including type of fluids, corrosion hazards, sour service, low temperature brittle failure and relaxation at elevated temperatures.The purpose of this document is to provide a selection of most commonly used bolting types and bolting material combinations as well a tool for easy selection of suitable bolting for equipment.It is not the intention to specify all possible applications but to give guidance on the most common applications. For example, application limits for material in the creep range are not explicitly covered in this document. Where material standard provides mechanical properties for the creep range, respective reference is made in Table 3.NOTE 2 Special services and ambient conditions could require the application of coatings. It is the purchaser's option to decide on this. Depending on the coating used, a verification of the temperature ranges given in Table 3 and Table 4 could be required.

This document specifies the gasket parameters required by EN 1591 1 and provides the test procedures for establishing the values of these parameters.Gaskets which are wholly based upon elastomers, or based upon elastomers with only the inclusion of particulate fillers or particulate reinforcement, as opposed to gaskets combining elastomers, fillers and fibrous reinforcement, are beyond the scope of this document.NOTE The testing procedures given might be applicable to gaskets of other shapes and dimensions.

This document specifies the quality assurance procedures that are applicable to ensure that delivered gaskets comply with the relevant product standards. This document sets down procedures by which a user can have confidence that the salient features of each batch of gaskets or gasket materials delivered to them will be constant.The gasket types covered by this document are those that are within the scope of the EN 1514 series and EN 12560 series and are simultaneously within the scope of the EN 1591 series. An exception is those gaskets intended solely for domestic fluids (like water, waste water ...) which are based on rubber with or without reinforcement like fillers and/or inserts.

This document specifies the method for the verification and validation of models for the determination of the property data of steels. It is applicable where modelling of mechanical or physical properties is used to substitute conventional testing for specific inspection. Models canbe based on statistical data, thermo-physical data or indirect measurement (e.g. measurement of magnetic or ultrasonic data).This document applies only for verification and validation of models for providing the properties of rolled or heat treated products such as plates, sheets, strip, sections, bars, etc.This document is used to demonstrate the ability of the model to supply property data which is equivalent to data, which is measured by conventional testing.NOTE: Validation of models is part of auditing the quality management system performed by an independent body.
