<p>This International Standard specifies principles and recommends procedures for the verification of the durability</p>
<p>of concrete structures subject to:</p>
<p>— known or foreseeable environmental actions causing material deterioration ultimately leading to failure</p>
<p>of performance;</p>
<p>— material deterioration without aggressiveness from the external environment of the structure, termed selfageing.</p>
<p>NOTE The inclusion of, for example, chlorides in the concrete mix might cause deterioration over time without the</p>
<p>ingress of additional chlorides from the environment.</p>
<p>This International Standard is intended for use by national standardization bodies when establishing or</p>
<p>validating their requirements for durability of concrete structures. It may also be applied:</p>
<p>— for the assessment of remaining service life of existing structures; and</p>
<p>— for the design of service life of new structures provided quantified parameters on levels of reliability and</p>
<p>design parameters are given in a national annex to this International Standard.</p>
<p>Fatigue failure due to cyclic stress is not within the scope of this International Standard.</p>
