28、d clay manholes and inspection chambers according to their requirements. This standard does not apply to manhole tops and cover slabs. NOTE 2 Corresponding provisions for the evaluation of conformity (ITT and FPC) and sampling and those for the test methods are further specified in EN 295-2 and EN 2
29、95-3, respectively. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
