1.1.     This document contains general principles and requirements for the competence, consistent operation and impartiality of bodies providing validation/verification as conformity assessment.

1.2.     Bodies operating according to this document can be first party, second party as well as third party bodies. Bodies can be validation bodies only, verification bodies only, or provide both activities.

1.3.     This document is applicable to validation/verification bodies in any sector, providing confirmation that claims are either plausible with regards to the intended purpose (validation) or correctly stated (verification). However, statements of conformity themselves, issued as result of another conformity assessment activity (e.g. testing, inspection and certification), are not considered to be subject to validation/verification according to this document.

1.4.     This document is applicable to any sector, in conjunction with sector specific programmes that contain requirements for validation or verification processes and procedures.

1.5.     This document can be used as a basis for accreditation by accreditation bodies, peer assessment within peer assessment groups, or other forms of recognition of validation/verification bodies by international or regional organizations, governments, regulatory authorities, programme owners, industry bodies, companies, clients or consumers.

NOTE          This document contains generic requirements and is neutral with regard to the operated validation or verification programme. Requirements of the applicable programmes are additional to the requirements of this document.

This document specifies the application of the time-of-flight diffraction (TOFD) technique in testing of metals for quantifying loss of thickness due to erosion and/or corrosion.

This document applies to all types of corrosion or erosion damage, particularly those defined in ISO 16809.

This test applies to unalloyed or low-alloyed steel materials.

It applies to components with a nominal thickness ≥ 6 mm. For smaller thicknesses feasibility tests will be performed to validate the technique.

For other materials, feasibility tests are essential too.

The TOFD technique can be used here as a stand-alone technique or in combination with other non-destructive testing techniques, during manufacturing and for testing in-service, in order to detect material loss caused by erosion and/or corrosion.

This technique is based on analysis of TOFD images established using reflected and/or diffracted ultrasonic signals.

This document does not specify acceptance levels.

This document defines requirements for short-range communication for the purposes of compliance checking in autonomous electronic fee-collecting systems. Compliance checking communication (CCC) takes place between a road vehicle's on-board equipment (OBE) and an outside interrogator (road-side mounted equipment, mobile device or hand-held unit), and serves to establish whether the data that are delivered by the OBE correctly reflect the road usage of the corresponding vehicle according to the rules of the pertinent toll regime.

The operator of the compliance checking interrogator is assumed to be part of the toll charging role as defined in ISO 17573. The CCC permits identification of the OBE, vehicle and contract, and verification of whether the driver has fulfilled his obligations and the checking status and performance of the OBE. The CCC reads, but does not write, OBE data.

This document is applicable to OBE in an autonomous mode of operation; it is not applicable to compliance checking in dedicated short-range communication (DSRC)-based charging systems.

It defines data syntax and semantics, but does not define a communication sequence. All the attributes defined herein are required in any OBE claimed to be compliant with this document, even if some values are set to “not defined” in cases where certain functionality is not present in an OBE. The interrogator is free to choose which attributes are read, as well as the sequence in which they are read. In order to achieve compatibility with existing systems, the communication makes use of the attributes defined in ISO 14906 wherever useful.

The CCC is suitable for a range of short-range communication media. Specific definitions are given for the CEN-DSRC as specified in EN 15509, as well as for the use of ISO CALM IR, the Italian DSRC as specified in ETSI ES 200 674-1 and ARIB DSRC as alternatives to the CEN-DSRC. The attributes and functions defined are for compliance checking by means of the DSRC communication services provided by DSRC layer 7, with the CCC attributes and functions made available to the CCC applications at the road-side equipment (RSE) and OBE. The attributes and functions are defined on the level of application data units (ADU).

The definition of the CCC includes:

—    the application interface between OBE and RSE (as depicted in Figure 2)

—    use of the generic DSRC application layer as specified in ISO 15628 and EN 12834

—    CCC data type specifications are given in Annex A, protocol implementation conformance statement (PICS) proforma

—    A protocol implementation conformance statement (PICS) proforma is given in Annex B

 

 

—    use of the CEN-DSRC stack as specified in EN 15509, or other equivalent DSRC stacks as described in Annex C, Annex D, Annex E and Annex F.

—    security services for mutual authentication of the communication partners and for signing of data (see Annex H).

—    An example CCC transaction is presented in Annex G.

—    The informative Annex I highlights how to use this document for the European electronic toll service (as defined in Commission Decision 2009/750/EC).
