6.8.2.3.3

the following requirements apply to tanks for which special provision ta4 of 6.8.4 (and therefore

1.8.7.2.4) does not apply.

the type approval shall be valid for a maximum of ten years. if within that period the relevant

technical requirements of adr (including referenced standards) have changed so that the approved

type is no longer in conformity with them, the competent authority or the body designated by that

authority which issued the type approval shall withdraw it and inform the holder of the type approval.

note: for the ultimate dates for withdrawal of existing type approvals, see column (5) of the tables

in 6.8.2.6 or 6.8.3.6 as appropriate.

if a type approval has expired or has been withdrawn, the manufacture of the tanks, battery-vehicles or

megcs according to that type approval is no longer authorised.

in such a case, the relevant provisions concerning the use, periodic inspection and intermediate

inspection of tanks, battery-vehicles or megcs contained in the type approval which has expired or

has been withdrawn shall continue to apply to these tanks, battery-vehicles or megcs constructed

before the expiry or the withdrawal if they may continue to be used.

they may continue to be used as long as they remain in conformity with the requirements of adr. if

they are no longer in conformity with the requirements of adr they may continue to be used only if

such use is permitted by relevant transitional measures in chapter 1.6.

type approvals may be renewed by a complete review and assessment for conformity with the

provisions of adr applicable at the date of renewal. renewal is not permitted after a type approval

has been withdrawn. interim amendments of an existing type approval not affecting conformity (see

6.8.2.3.2) do not extend or modify the original validity of the certificate.

note: the review and assessment of conformity can be done by a body other than the one which

issued the original type approval.

the issuing body shall keep all documents for the type approval for the whole period of validity

including its renewals if granted.

if the designation of the issuing body is revoked or restricted, or when the body has ceased activity,

the competent authority shall take appropriate steps to ensure that the files are either processed by

another body or kept available.
