1 Scope This standard describes methods for the determination of the thickness of sprayed concrete on a substrate after spraying. The results can also give an indication of the parallelism of the concrete to the substrate. The substrate may be rock, soil, concrete or other surface. 2 Normative references The following referenced documents are indispensable for the application of this […]

1 Scope This European Standard specifies a method for sampling of slurry mixtures for extraction tests. The Standard applies to slurry surfacings for roads, airfields and other trafficked areas. 2 Apparatus 2.1 Plastic container with a capacity of at least 3 l. 2.2 Stirring rod, with a diameter of 20 mm to 30 mm and a suitable length. 3 Procedure […]

6.2 Repair requirements The repair requirements for each class (see Clause 5) are specified in EN 1 01 63-2 and EN 1 01 63-3. 6.3 Repair procedures 6.3.1 Grinding If a discontinuity has to be repaired, it shall be removed completely by grinding to its full depth. The ground areas shall have a smooth transition to the surrounding surface of […]

1 Scope This European Standard specifies the grades of continuously hot rolled low carbon steel sheet and strip (in coils) for cold forming. Depending on its actual width, strip is classified as: hot rolled wide strip if its width is greater than or equal to 600 mm; hot rolled slit wide strip if its width is less than 600 mm. […]

1 Scope 1.1 This European Standard gives the technical delivery requirements for: semi-finished products, hot formed, for example blooms, billets, slabs (see NOTE 2 and NOTE 3),bars (see NOTE 2),rod, wide flats, quarto plates, hot-rolled sheet/plate and strip, hammer and drop forgings (see NOTE 2), manufactured from the case hardening non alloyed or alloyed steels (see NOTE 4) listed in […]

1 Scope This standard defines the minimum clearance area required around nuts and bolt heads when using either double hexagon box or socket wrenches defined in AECMA standard. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced […]

1 Scope This standard specifies holes in common parts and sheet metal for 1 00° countersunk head screws with nominal diameters of 3 mm to 5 mm and head configuration according to EN standards for aerospace applications. 2 Use 2.1 Normal application Underflush condition, i. e. where units are mounted on top of the screws, use dimensions P 1 (see […]

1 Scope The purpose of this standard is to define the characteristics of the fluid fittings, flanged, straight, sealing by Oring, for 0,8 mm thick tubes. NOTE Flanged fitting installation hole and assembly, see EN 3633 and TR 3634. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition […]

1 Scope This standard specifies the dimensions of the uncoated double hexagon head bolts, close tolerance, with MJ thread, medium thread length, in heat resisting steel FE-PM38 for aerospace applications. Maximum test temperature of the parts is 550 °C. These bolts are to be used in aerospace fastening systems mainly stressed in shearing force. 2 Normative references The following referenced […]

1 Scope This standard specifies the performance and test requirements for solid rivets in the nickel alloys quoted below, intended for aerospace applications. It applies wherever it is specified in the document defining the rivet. Its use, after agreement between the customer and the supplier, for solid rivets made from other materials, requires determination, case by case, of the minimum […]
