TS 13090

TS 13090 is a guidance standard prepared on the basis of EA 9/01 and intended to support the application of TS EN 45503. Its technical subject is the assessment of contract award procedures in the water, energy, transport and telecommunication sectors, with an emphasis on creating a common interpretive basis for accreditation bodies, assessors and attestation bodies.

Application context and technical meaning

This is not a product standard; it is an explanatory guide for applying an attestation standard. In practical terms, its value lies in helping readers understand how procurement, evaluation, decision-making and contract award processes should be viewed through the lens of conformity assessment. In general technical context, guidance documents of this type support consistent interpretation, comparability between assessments and alignment of practices across different sectoral environments.

Why the standard matters in accreditation practice

• It clarifies the accreditation body’s approach to EN 45503.
• It gives assessors a common vocabulary and interpretive framework.
• It supports attestation bodies during their preparatory work.
• It helps place contract award procedures within a consistent conformity assessment model across sectors.

This edition is withdrawn, so its main value is historical and reference-based. Even so, it remains useful for understanding the relationship between EA 9/01 and TS EN 45503 and for situating attestation-related procedures within the broader field of accreditation and conformity assessment.
