It specifies standards and additional requirements for dimensions, materials and technical conditions of delivery for bolting. The bolting selection covered by this European Standard is regarded to be used for combination with flanges according to the series EN PN designated flanges and the series EN Class designated flanges. The selection is based on commonly used materials, bolts and nuts. It covers temperature ranges of the general service of standard flanges based on PN or Class.

Dourg Home BS EN 1 In general, bolting will be delivered: Table 5 — Requirements for prevention of brittle fracture with reference thickness for nuts and bolts with starting material according to EN Type of material 1. A version in any other language made by translation under the responsibility of CEN member into its own language sn notified to the CEN Management Centre has the same status as the official versions.
Inchiesta pubblica preliminare UNI: The bolting selection covered by this European Standard is regarded to be used for combination with flanges according to the series EN PN designated flanges and the series EN Class designated flanges. This does not preclude the free use, in the course of implementing the standard, of necessary details such as symbols, and size, type or grade designations.
Politica europea sulla normazione Normazione e professioni non regolamentate. Data entrata in vigore: Various BSI electronic information services are also available which give details on all its products and services. Some bolting materials enn in Tables 4 and 5 are not covered by Table 3, but tM is given in addition. The internal thread of the nut will usually be machined.
Please e this form, we will try to respond as soon as possible. It is not the intention to specify all possible applications but to give guidance on the most commonly applications. Consequently the technical data stated in the material standard shall be assessed against the design requirements of this specific item of equipment to verify that the ERs of the PED are satisfied.

It specifies standards and additional requirements for dimensions, materials and technical conditions of delivery for bolting. Wherever the starting material standard provides mechanical properties for this temperature range respective reference is made in Table 3. It is the constant aim of BSI to improve the quality of our products and services.
Details and advice can be obtained from the Copyright and Licensing Manager. For some materials mechanical properties at higher temperature exist, e. Nuts with specified proof load values — Coarse thread ISO NOTE 1 The bolting selection given may be used in combination with non-standard flanges too provided that the range of application of the equipment for which the bolting is intended to be used is covered.
Depending on the coating used, a verification of the temperature ranges given in 3 may be required. The purpose of this European Standard is to provide a selection of most commonly used bolting types and bolting material as well a tool for easy selection of suitable bolting for equipment.
Nuts should be obtained, preferably, by forging. Information on standards BSI provides wide range of information on national, European and international standards through its Library and its Technical Help to Exporters Service.
Other properties like residual magnetism and relaxation properties shall be evaluated by the purchaser. Buying standards Orders for all BSI, international and foreign standards publications should be addressed to Customer Services. Leggere attentamente le istruzioni prima di effettuare il download. Bolts, screws and studs with specified property classes — Coarse thread and fine pitch thread ISO The bolting selection covered by this European Standard is regarded to be used for combination with flanges according to the series EN PN designated flanges and the series EN Class designated flanges.
Mami Cold working is just necessary and therefore permitted for austenitic stainless steel bolting in accordance to property class 70 and for nuts in accordance to property classes 5 and 8.
