Standardization in Germany Organization and principles Standardization is instrumental in the creation of order in our technical world. It is an integral part of the existing economic, social and legal structure. DIN Deutsches Institut für Normung e. V. (DIN, for short), a self-governing institution of trade and industry, is the body responsible in Germany for the preparation of national standards. It performs this function on the basis of its statutes and of the principles set out in DIN 820, and pursuant to the agreement concluded with the German Federal Government in 1975. As the representative of Germany, it fulfils an equivalent function in the European (CEN/CENELEC) and international (ISO) standards organizations, while in the field of electrical engineering such activities are coordinated through the DKE Deutsche Kommission Elektrotechnik Elektronik Informationstechnik im DIN und VDE. The standards work undertaken by DIN is a service that profits the whole of the national economy. This work is defined as the systematic standardization of tangible and intangible objects by the mutual efforts of all interested parties for the benefit of the entire community.

The { symbol The { symbol is the visible representation of DIN’s work for the benefit of the community. Its use is not restricted to DIN members, but all products bearing the { symbol must comply with the pertinent DIN Standards and meet other justified requirements with regard to their serviceability. If products bearing the symbol are found not to comply with the provisions laid down for its use, permission to use the mark will be withdrawn.

Membership of DIN Membership of DIN is open to companies and corporate bodies from any country. Members of DIN pay an annual subscription fee which is based on the number of salaried staff and wage-earners (discounting apprentices/trainees) employed in their organization. The current minimum fee is EUR 744.00 (for all organizations with up to 100 employees). Members of DIN are granted, among other benefits, the following reductions: – 15 % discount on orders for the DIN-Katalog für technische Regeln, © DIN Deutsches Institut für Normung e. V. DIN Handbook 404

– 15 % discount on orders for DIN Standards, including translations, – 15 % discount on subscriptions to DIN-Mitteilungen + elektronorm, and – permission to reproduce DIN Standards for in-house purposes against payment of a small flat-rate fee.

Information on standards The results of DIN’s activities in the field of standardization are recorded in DIN Standards. In special fields and areas of responsibility, other German private-sector regulatory bodies also issue normative documents.

The main annual catalogue published by DIN is the DIN-Katalog für technische Regeln, edited by the DITR-Datenbank der DIN-Software GmbH. Volume 1 of the DIN Catalogue represents the single most comprehensive printed source of information on the technical rules which are valid in Germany; volume 2 contains the corresponding references to international collections of technical rules. Both volumes are also available on CD-ROM. The technical rules listed in this catalogue are not only DIN Standards and documents published by other regulatory bodies, but also those statutory provisions (laws, regulations, etc.) that contain technical specifications. The titles of the documents are in many cases given in both German and English. DIN publishes a monthly journal, the DIN-MITTEILUNGEN + elektronorm which, besides featuring articles and reports on standards work in Germany and abroad, also includes a gazette of new publications and other activities in the field of technical rules, the DIN-Anzeiger für technische Regeln. In addition to the printed products, DITR also offers a large number of other services.

Translations of German standards DIN-Sprachendienst, the language services section of DIN, publishes official English translations of the most important DIN Standards. These translations may be purchased singly or on a subscription basis. In addition to the printed translations, the Auslandsnormen-Service (Foreign Standards Sales Section) maintains a large collection of typescript translations in English, French and Spanish which outside companies and organizations have been authorized to prepare, but which have not been reviewed by DIN. The essential bibliographic data of all available translations, in both printed and typescript formats (2005: 18,500), are referenced in the translations catalogue published annually as Volume 3 of the main DIN-Katalog für technische Regeln.

Terms of delivery and payment of Beuth Verlag 1.

Unless otherwise expressly confirmed by Beuth Verlag in writing, the terms of delivery and payment of Beuth Verlag apply to the exclusion of all others. They are also binding in cases where contrary purchase conditions of the customer are not explicitly rejected. In transactions with book trade distributors, the provisions of the current version of the German book trade code apply supplementarily.

2.

For electronic products, these terms of delivery and payment are supplemented by the general terms and conditions applicable to the product concerned and incorporated in the contract relating to it.

3.

Delivery of goods shall be subject to their availability. In accordance with §§ 447 and 448 of the Bürgerliches Gesetzbuch (German Civil Code), all goods are consigned for the account and risk of the purchaser. This expressly includes the forwarding charges.

4.

The period of warranty shall be twelve months. The customer shall report any faulty goods in writing to Beuth Verlag within eight days of receipt.

5.

Claims for damage occurring in transit shall be made to the carrier and not to Beuth Verlag.

6.

Claims for damages by the customer on any legal grounds are excluded, in particular those arising from breaches of contract and unlawful acts. This does not apply in cases where, for example, the Produkthaftungsgesetz (German Product Liability Law) applies, in cases involving intent, gross negligence or injury, where a warranty covers a

particular aspect of the goods or where contractual obligations are breached. Liability for breaching contractual obligations shall be limited to damage that can be reasonably predicted within the terms of the contract, provided there is no evidence of intent or gross negligence and no liability is to be accepted for a specific aspect of the goods. This shall not shift the burden of proof to the disadvantage of the customer. 7.

Until final payment of all claims resulting from the business transaction has been made, the goods supplied shall remain the property of Beuth Verlag. In the case of more than one claim or an unpaid invoice, reservation of ownership shall serve as a warranty against payment pending payment in full, even if payment for individual deliveries has already been made. With the order, the customer assigns to the seller all claims deriving from resale and the seller accepts such assignment on taking the order.

8.

The invoice amounts are, unless otherwise indicated on the invoices, due immediately and without deductions. No cash discount shall be granted. At least EUR 5.00 will be charged for requesting payment, in addition to interest at the standard bank rate. Beuth Verlag is entitled to submit claims to the customer for any additional costs incurred. If the customer defaults on payment or if Beuth Verlag has reason to believe that the creditworthiness of the customer is at risk, Beuth Verlag is entitled to hold back delivery or to demand prepayment.

9.

Technical rules, such as DIN Standards and VDI Codes of practice, are not book trade articles. Beuth Verlag grants no trade discount on them. They may not be returned or exchanged unless faulty.

10. If Beuth Verlag, despite being under no legal obligation to do so, agrees to take back goods at the request of the customer, it may charge a handling fee of 10 % of the invoice amount or at least EUR 15.00. 11. The place of performance and jurisdiction is Berlin. 12. Transactions with customers abroad shall be subject to German substantive law only. The Hague Conventions relating to a Uniform Law on the International Sale of Goods and the UN Sales Convention shall not apply.

13. Beuth Verlag uses data processing facilities and stores customer information for its business purposes and within the scope permitted by the Bundesdatenschutzgesetz (Federal Data Protection Act). A data protection officer has been appointed. The customer agrees to Beuth Verlag storing and processing his data, and making it available to businesses within the DIN Group for advertising purposes. The customer may withdraw his consent at any time for his data (name, title and address only) to be made available for advertising purposes. E-mail advertising may not be used without the express consent of the customer. Valid as of August 2002.

Copyright DIN Deutsches Institut für Normung e. V. holds the exploitation rights to the copyright on DIN Standards (DIN-Normen) and on their translations. No part of DIN Standards may be reproduced without prior permission from DIN. Requests for such permission should be addressed to: DIN Deutsches Institut für Normung e. V. Rechtsabteilung (Legal Department) 10772 Berlin, Germany.

Compliance with DIN Standards As a rule, the specifications given in DIN Standards are implemented because they are deemed to represent good practice, and not because legislation has made compliance with them mandatory. An obligation to comply with DIN Standards may, however, devolve from contractual agreements (e.g. between supplier and purchaser), or in those instances where DIN Standards have been incorporated in German laws or statutory regulations. Even if compliance with DIN Standards is not explicitly stipulated, many contracts, regulations and specifications state in general terms that certain products or procedures must conform to the state of the art or good practice as documented in DIN Standards.

Exclusion of liability DIN Standards are available for use by anyone, this person being directly responsible for correctly applying the information contained therein. DIN Standards are not the sole source of information on correct technical procedures applicable under normal conditions, but just one such source. It should also be borne in mind that DIN Standards can only reflect the state of the art existing at the time of their publication. Compliance with DIN Standards does not, in itself, confer immunity from legal obligations. In this regard, each person bears the risk of his/her own action. Any liability on the part of DIN Deutsches Institut für Normung e. V. or of those persons involved in the preparation of DIN Standards is excluded.

Anyone finding an inaccuracy, error, or ambiguity when applying a DIN Standard is requested to notify DIN immediately so that prompt action can be taken.

Foreword The move away from standardization at the national level towards an emphasis on the European level continues at a rapid pace. This dynamic process presents a special challenge for those working in the iron and steel sectors, especially since steel grades and product forms are being standardized for which no German standard exists. In addition, national steel standards are being replaced almost daily by European Standards. In order to keep abreast with this progress, it is necessary to publish new editions of the DIN Handbooks on iron and steel at regular intervals. As with the previous edition, this set of Handbooks (DIN Handbooks 401 to 405) is divided up according to subject area. This volume, DIN Handbook 404, contains 10 new European Standards which have replaced national standards. Two standards have been revised for this edition (DIN EN 10084 and DIN EN 10132-4). It should be noted that, although draft standards appear in the original German Handbooks, the English versions of these drafts are not included here. Such temporary editions may be significantly altered in their final form, and so a decision was made to await the publication of the final versions of DIN EN Standards. The English equivalents become available shortly afterwards and may be ordered individually from Beuth Verlag.

Foreword This European Standard has been prepared by ECISS/TC 23 “Steel for heat treatment, alloy steels and free-cutting steels – Qualities”, the Secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, and conflicting national standards withdrawn, by July 1998 at the latest. In accordance with the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, the Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, the Netherlands, Norway, Portugal, Spain, Sweden, Switzerland, and the United Kingdom. The United Kingdom will issue a non-conflicting national addition which describes a steel used in the United Kingdom but is not included in this European Standard.

Elements not quoted in this table shall not be intentionally added to the steel without the agreement of the purchaser, other than for the purpose of finishing the heat. All reasonable precautions should be taken to prevent the addition from scrap or other material used in manufacture, of such elements which affect the hardenability, mechanical properties and applicability. Where requirements are made on hardenability (see tables 5 and 6), slight deviations from the limits for the cast analysis are permitted, except for phosphorus and sulfur; these deviations shall, however, not exceed, in the case of carbon, t 0,01% and in all other cases, the values specified in table 4. Steels with improved machinability as a result of the addition of lead or higher sulfur contents, depending on the manufacturing process up to around 0,100 % S (including controlled sulfide and oxide formation, e.g. calcium treatment), may be supplied on request. In this case, the upper limit of the manganese content may be increased by 0,15 %. Boron in this case is not added to increase hardenability but to improve the toughness of the case-hardened zone.

t means that in one cast the deviation may occur over the upper value or under the lower value of the specified range in table 3, but not both at the same time. For steels with a specified sulfur range (0,020 % to 0,040 % according to cast analysis), the permissible deviation is t 0,005 %.

The temperatures given for carburizing, core-hardening, case-hardening and tempering are for guidance; the actual temperatures chosen should be those that will give the properties required. Time for austenitizing as a guide: 0,5 h minimum. The carburizing temperature will depend on the chemical composition of the steel, the mass of the product, and the carburizing medium. If the steels are direct hardened, in general, a temperature of 950 °C is not exceeded. For special procedures (e.g. under vacuum), higher temperatures (e.g. 1 020 to 1 050 °C) are not unusual. When applying the single quench method, the steel is to be quenched from the carburizing temperature or a lower temperature. The lower hardening temperatures are in each case to be preferred, in particular when there is risk of distortion. The kind of quenching agent depends on, for example, the shape of the products, the cooling conditions and the amount of furnace filling. Time for tempering as a guide: 1 h minimum.

) The temperatures given for carburizing, core-hardening, case hardening and tempering are for guidance; the actual temperatures chosen should be those that will give the properties required. 2) The carburizing temperature will depend on the chemical composition of the steel, the mass of the product, and the carburizing medium. If the steels are direct hardened, in general, a temperature of 950 °C is not exceeded. For special procedures, for example under vacuum, higher temperatures (for example 1 020 to 1 050 °C) are not unusual. 3) When applying the single quench method, the steel is to be quenched from the carburizing temperature or a lower temperature. The lower hardening temperatures are in each case to be preferred, in particular when there is risk of distortion. 4 ) The kind of quenching agent depends on, for example, the shape of the products, the cooling conditions and the amount of furnace filling. 5) Time for tempering as a guide: 1 h minimum.
