Bituminous mixtures - Test methods - Part 17: Particle loss of porous asphalt specimens
This European Standard specifies a test method for determining the particle loss of porous asphalt mixtures. Particle loss is assessed by the loss of mass of porous asphalt samples after turns in the Los Angeles machine. This test enables the estimation of the abrasion resistance of porous asphalt. The test applies to laboratory compacted cylindrical specimens of porous asphalt mixtures, the upper sieve size of which does not exceed 22,4 mm. It does not reflect the abrasive effect by studded tyres.

This European Standard describes a test method for determining the particle loss of porous asphalt mixtures. Particle loss is assessed by the loss of mass of porous asphalt samples after turns in the Los Angeles machine. This test enables the estimation of the abrasiveness of porous asphalt. The test applies to laboratory compacted porous asphalt mixtures the upper sieve size of which does not exceed 25 mm. It does not reflect the abrasive effect by studded tyres.

Railway applications - Track - Test methods for fastening systems - Part 7: Determination of clamping force and uplift stiffness
This European Standard specifies a laboratory test procedure for determining the clamping force exerted by the fastening system on the foot of a rail by measuring the force to separate the rail foot from its immediate support. When required the procedure is also used to determine the uplift stiffness of the fastening system. It is applicable to systems with and without baseplates on all types of sleepers, bearers and elements of slab track. The test does not determine the security of fastening components fixed into the sleeper or other fastening system support. This test procedure applies to a complete fastening assembly. It is not applicable to fastening systems for embedded rail.

Railway applications - Track - Test methods for fastening systems - Part 1: Determination of longitudinal rail restraint
This European Standard specifies a laboratory test procedure to determine: - the maximum longitudinal force that can be applied to a rail, secured to a sleeper, bearer or element of slab track by a rail fastening assembly, without non-elastic displacement of the rail occurring, or - the longitudinal stiffness at a specified longitudinal displacement of a specimen of embedded rail with an adhesive fastening system, and, (for any type of fastening system) - to determine values of shear displacement and slip data for track-bridge interaction calculations

Railway applications - Infrastructure - Non-destructive testing on rails in track - Part 4: Qualification of personnel for non-destructive testing on rails
This part of this European Standard defines the requirements for qualification of the personnel who plan, carry out and supervise non-destructive testing in industrial sector - Railway maintenance infrastructure, on rails in switches, crossings and plain track. Safety of staff working on or near the railway track is part of the infrastructure manager safety management system and is not part of this standard. This part of this European Standard applies only to rail profiles meeting the requirements of EN 13674 1 and EN 13674-2.

Railway applications - Infrastructure - Non-destructive testing on rails in track - Part 3: Requirements for identifying internal and surface rail defects
This part of this European Standard specifies the NDT methods used to detect internal and surface rail defects and the suitability of each method for the detection and evaluation of typical rail defects of rails installed in track. This part of this European Standard does not specify the assessment criteria of rail defects and the derived actions. This part of this European Standard applies only to rail profiles meeting the requirements of EN 13674-1.
