DIN EN 1829-2:2012-02 4 Introduction This European Standard is a type C standard as stated in EN ISO
23、 12100-1. The machinery concerned and the extent to which hazards, hazardous situations and hazardous events are covered are indicated in the scope of this European Standard. When provisions of this type C standard are different from those which are stated in type A or B standards, the provisions of
24、 this type C standard take precedence over the provisions of the other standards, for machines that have been designed and built according to the provisions of this type C standard. EN 1829-2:2008 + AC:2011 (E) DIN EN 1829-2:2012-02 5 1 Scope This European Standard applies to hoses, hose lines and c
25、onnectors intended to be used with high-pressure water jet machines within the scope of prEN 1829-1. This European Standard deals with all significant hazards, hazardous situations and events relevant to the equipment in the scope, when it is used as intended and under conditions of misuse which are
26、 reasonably foreseeable by the manufacturer (see clause 4). This European Standard deals with safety requirements to minimise the significant hazards which can arise from assembling, operating and servicing of hoses, hose lines and connectors for use with high pressure water jet machines (see clause
27、 5). NOTE 1 This European Standard does not cover leak shields since they are not part of a hose line. The hazard due to scalding from hot liquid or from irritation / burning of any added chemicals is not covered in this European Standard. This European Standard is not applicable to hoses, hose line
28、s and their accessories, which are manufactured before the date of its publication as EN. NOTE 2 For products of similar application that are outside of the scope of this European Standard and for which there is no alternative document available the relevant Clauses of this European Standard may be
29、used. EN 1829-2:2008 + AC:2011 (E) DIN EN 1829-2:2012-02 6 2 Normative references The following referenced documents are indispensable for the application of this document.

33、 terms and definitions given in EN ISO 12100-1:2003, prEN 1829-1:2007 and the following apply. 3.1 burst pressure static pressure that destroys the hose line and allows the liquid to escape 3.2 interconnected hose lines several hose lines which have been connected to each other 3.3 connector safety
34、devices parts or components to restrain movement of the hose line if the connector fails (e.g. locking collars, hose sleeves, etc.) 4 List of significant hazards 4.1 General This Clause contains all the significant hazards, hazardous situations and events, as far as they are dealt with in this Europ
35、ean Standard, identified by risk assessment as significant for this type of machinery and which require action to eliminate or reduce the risk. 4.2 Hazards due to bursting or leaking of hoses Hazards can occur when a hose bursts or leaks. The escaping stream of liquid can cause physical damage and a
36、lso a sudden repositioning of the hose line in a dangerous manner (whip). EN 1829-2:2008 + AC:2011 (E) DIN EN 1829-2:2012-02 7 4.3 Hazards due to failure of connectors Hazards can occur when a connector fails. The escaping stream of liquid can cause physical damage and also a sudden repositioning of
37、 the hose line in a dangerous manner (whip). 4.4 Hazards due to errors by the operator Hazards can occur if the operator uses incompatible substances or incompatible components. Hazards can also occur if the operator exceeds the limits of use specified by the manufacturer (e.g. too high pressure, to
38、o high tensile stress). 4.5 Hazards due to change in length of hose line Hazardous situations occur when there is a sudden change of pressure in the hose line causing a change in length resulting in the operators losing their firm hold. 5 Safety requirements and/or protective measures 5.1 General Ho
39、ses, hose lines and their connectors shall comply with the safety requirements and/or protective measures of this Clause. In addition, they shall be designed according to the principles of EN ISO 12100-2 for relevant but not significant hazards, which are not dealt with by this European Standard. Ho
40、ses, hose lines, and connectors have to feature a certain structure in order to guarantee safe operation when used properly. They must not bear any risks for the operator or for the workplace and its environment. The design of any connector safety devices has to provide safe operational performance
41、to eliminate any risk or hazard for the operator or their environment. However, improper use of a hose line or the connectors may result in hazardous situations and must be avoided. NOTE Correct assembly of hose lines requires specific knowledge and skills and also specific equipment. 5.2 Requiremen
42、ts for compatibility of components The hoses and connectors combined to hose lines have to match each other in terms of structure, composition, and design. NOTE Hoses of one manufacturer do not necessarily match connectors of another manufacturer. 5.3 Mechanical requirements All components of a hose
43、 line as well as the connectors and the hose line itself shall not fail under the burst pressure specified by the manufacturer. 5.4 Requirements concerning the maximum allowable working pressure for hose lines For hose lines with maximum allowable working pressure up to or equal to 3 000 bar the bur
44、st pressure shall be at least 2,5 times the maximum allowable working pressure. For hose lines with maximum allowable working pressure above 3 000 bar the burst pressure shall be at least two times the maximum allowable working pressure. (See also EN ISO 7751.) 5.5 Thermal requirements The hose line
45、s shall be suitable for operating temperatures above -10 C and below +70 C. EN 1829-2:2008 + AC:2011 (E) DIN EN 1829-2:2012-02 8 5.6 Requirements concerning change in length of hose lines Any change in length shall not exceed +/- 2 % of the original length when subjected to the maximum allowable wor
46、king pressure. 5.7 Requirements for tensile strength of hose lines The hose lines shall withstand a tensile force equivalent to that induced by a pressure equal to 1,5 times the maximum allowable working pressure or 1 000 N whichever is the lower value. 5.8 Requirements for loosening connectors Meas
47、ures shall be taken against the hazards of the unintentional loosening of connectors whilst the hose line is under pressure. One method is a design where the presence of pressure becomes apparent when starting loosening, for example by the use of swivel nuts with at least two axial relief bores. If
48、sufficient technical measures are not possible the manufacturer shall provide appropriate warnings and instructions (see Clause 7). NOTE For maximum allowable working pressure under 500 bar, standard hydraulic connectors are considered to satisfy this requirement. Pin nuts (swivel nuts which are fixed with a stainless steel pin) at connectors are only permissible up to 500 bar maximum allowable working pressure. 5.9 Requirements for connector safety devices The need for connector safety
