DIN shall not be held responsible for identifying any or all such patent rights. Amendments This standard differs from DIN 906:1992-01 as follows: a) pipe plugs
6、 with hexalobular socket and 12 point socket have been included; b) the title of the standard has been changed; c) symbol b has been replaced by lt; d) Clause 3 listing additional symbols and quantities has been added; e) Figure 1 has been revised and Figures 2 and 3 have been added; f) the technica
7、l delivery conditions have been completely revised, and the materials now also include aluminium alloys and copper-zinc alloys; g) normative references have been updated.

8、ns, masses and technical delivery conditions for pipe plugs which are intended to be screwed into holes with parallel thread as specified in DIN 158-1, DIN 3858, DIN EN ISO 228-1 and DIN ISO 261. NOTE 1 Since tightness is a function of pressure, temperature, the materials involved and the fluid with
9、 which the threaded parts are in contact, such connections cannot be assumed to be tight. Therefore, it is recommended that a sealant or seal ring should be provided, particularly where the hole has a thread as specified in DIN ISO 261. NOTE 2 For pipe plugs for use in gas and water supply systems,
10、see the Technische Regeln fr Gasinstallationen (DVGW-TRGI) (DVGW Codes of practice for gas installations)1)and DIN 1988-2. 2 Normative references The following referenced documents are indispensable for the application of this document.
