It is stipulated in the Landesbauordnungen ('Building Regulations of the Land') that the technical rules introduced by publication by the highest construction supervision authorities of the Laender are to be observed.

One of the tasks of Deutsches Institut für Bautechnik is to draw up the technical rules for construction products and types of construction in the Bauregellisten ('Construction Products Lists') A and B as well as in List C and to publish them in agreement with the highest construction supervision authorities of the Laender.

The Lists are revised annually and published by DIBt in its periodical 'DIBt Mitteilungen'. Beginning with the publication 2005/1 they can also be obtained online.

Please note:
The resulting changes and amendments of the Bauregellisten ('Construction Products Lists') A and B and the List C will be published on the Internet of DIBt as draft versions. The circles concerned have the possibility to comment on the amended versions. The comments shall be addressed to DIBt within three months as of the date of publication. The respective current draft amendments can also be ordered in writing from DIBt, Ms Gerloff, Kolonnenstr. 30 L, 10829 Berlin, tel.: (030) 787 30-353. Start and end date of the period for comments is clearly pointed out on the internet page and in the 'DIBt Mitteilungen' of the Institute.

Furthermore, the amendments to and additions of the list of Technische Baubestimmungen ('Acknowledged technical rules for works') (Parts I to III) concerning the application regulations for technical specifications (hEN, ETAG and ETA) according to the Construction Products Directive will also be published in order to give to planners, manufacturers and users the possibility to be prepared for the new legal situation in due time.

Bauregellisten A and B as well as List C consist of several parts with different areas of regulation.

Bauregelliste A Part 1, Part 2 and Part 3

	Bauregelliste A Part 1 In Bauregelliste A Part 1 the construction products are published where technical rules exist (regulated construction products), the rules themselves, the required attestation of conformity and in case of deviations the necessary verifications of applicability.
	Bauregelliste A Part 2 Bauregelliste A Part 2 applies to not regulated construction products which do not serve to fulfill considerable requirements of the safety of construction works and where generally acknowledged rules of technology do not exist either or which will be evaluated according to generally recognized test methods.
	Bauregelliste A Part 3 Bauregelliste A Part 3 applies to not regulated types of construction accordingly.

Bauregelliste B Part 1 and Part 2

Those construction products are included in Bauregelliste B which, according to the provisions of the Member States of the EU – German provisions included – and the contracting states of the Agreement establishing the European Economic Area to transpose EU Directives, may be placed on the market and traded and those which have the CE marking.

Bauregelliste B Part 1 The Bauregelliste B Part 1 is reserved for products which are placed on the market based on the Bauproduktengesetz ('Construction Products Law'), where technical specifications and depending on the intended use classes and performance levels exist. In addition, the application standards and regulations for the construction products and kits in accordance with technical specifications (hEN, ETAG and ETA) according to the Construction Products Directive are given in the list of Technische Baubestimmungen ('Acknowledged technical rules for works').

Bauregelliste B Part 2 Those construction products are included in Bauregelliste B Part 2 which are placed on the market due to other directives than the Construction Products Directive, which have the CE marking and which do not meet all the essential requirements under the Bauproduktengesetz ('Construction Products Law'). Additional verifications of applicability are therefore required.

List C

List C includes construction products which are not regulated, where neither Technische Baubestimmmungen ('Acknowledged technical rules for works') nor rules of technology exist and where fulfillment of requirements in the field of building law only play a minor role.
