Building Materials primarily made from Waste Glass RAL-UZ 49

1 Preliminary Remarks:

In cooperation with the Federal Minister for the Environment, Nature Conservation and Nuclear Safety, the Federal Environmental Agency and considering the results of the expert hearings conducted by RAL, the Environmental Label Jury has set up these Basic Criteria for the Award of the Environmental Label.
RAL, reg. assoc., has been entrusted with the award of the Environmental Label.
Upon application to RAL and on the basis of a Contract on the Use of the Environmental Label to be concluded with RAL the permission to use the Environmental Label may be granted for all products, provided that they comply with the requirements as specified hereinafter.

Award of the Environmental Label to building materials and auxiliary building materials primarily made from waste glass is to promote the use of glass wastes for construction purposes which are difficult to recycle because of their non-homogeneous composition.

1.3 Definition
Waste glass according to para. 1.2 is residual glass arising outside applicant's firm and which - if not recycled - would have to be disposed of as wastes, e.g. container glass from waste-glass collections, broken glass from the beverage industry, flat glass processing, etc. (external recycling of residual material for the purpose of waste avoidance).
Broken glass, glass wastes and rock wool wastes arising inside applicant's own firm(s) (internal recycling of residual material) shall not be considered as waste glass within the meaning of these Basic Criteria RAL-UZ 49.

2 Scope
These Basic Criteria apply to building materials and auxiliary building materials for overground workings, such as heat insulators, building blocks, mortar for lightweight walls, plaster and building materials, ceiling slabs and lightweight concrete.
Excluded are glass wool and other glass fibers which contain or set free fibre dusts which are according to the criteria laid down in TRGS 905 classified as carcinogenic or suspected of causing cancer.

3 Requirements
The Environmental Label shown on page 1 may be used for the marking of products listed under paragraph 2, provided that they comply with the following requirements:

The products must be primarily made from waste glass. They must not contain any screen glass.

The waste glass content of the finished product (building materials and auxiliary building materials) must be at least 51 weight per cent, or

in those cases where building materials are manufactured by the use of auxiliary building materials made from waste glass, the waste glass content of the finished product must be at least 70% by volume. Auxiliary building materials made from waste glass must fully substitute other auxiliary building materials serving the same purpose (e.g. expanded clay, expanded shale, sand and gravel).

The products must not contain any substances 1) which:

are listed in Annex I to Directive 67/548/EEC 2) or in the publication of the List of Dangerous Substances and Preparations 3) according to Section 4a, para. 1, Gefahrstoffverordnung (Ordinance on Hazardous Substances) 4), as amended, or must be classified according to Section 4a, para. 3, Ordinance on Hazardous Substances, and marked with the danger criteria/symbols and characteristic letters "very toxic" (T+), "toxic" (T), "carcinogenic", "mutagenic", "teratogenic" or "dangerous to the environment" (N), respectively;

are classified in TRGS 905 5) or in the MAK-value-List 6), as amended, as
a) carcinogenic according to EC Category Carc.Cat. 1, Carc.Cat. 2 or Carc.Cat. 3 or according to the MAK classification III1, III2 or III3;
b) mutagenic according to EC Category Mut. Cat. 1, Mut.Cat. 2 or Mut. Cat. 3 or M1, M2, or M3;
c) teratogenic according to EC Category Repr.Cat. 1, Repr.Cat. 2 or Repr. Cat. 3 or RE/F1, RE/F2 or RE/F3

or which according to scientific knowledge must be classified in one of the categories under para.3.1.2 as carcinogenic, teratogenic or mutagenic or have sensitizing or other chronically damaging properties or which as such or as their impurities or decomposition products are apt to cause considerable risk or considerable disadvantage for the public.

3.2.4 Exception:

Production-related impurities of substances under paras.3.2.1 and 3.2.2 must not exceed 0.01 weight per cent in the fabricated materials.
Notwithstanding this, carcinogenic, mutagenic and teratogenic substances shall be minimized in keeping with the latest technological findings.

Darüber hinaus dürfen Stoffe oder Zubereitungen 1) die in der Bekanntmachung der Liste der gefährlichen Stoffe und Zubereitungen 3) nach § 4a Abs.1 GefStoffV 4) in ihrer jeweils gültigen Fassung aufgeführt bzw. nach § 4a Abs.3 GefStoffV:

are classified or marked as "low-toxic" (Xn), "irritating" (Xi), "caustic" (C), must not exceed a maximum content of 50.0 weight per cent of the limiting concentration in the final product calculated according to Annex II, No.1, Ordinance on Hazardous Substances;

are classified on the basis of their physico-chemical properties, may be included in the final product up to a maximum content up to which a risk marking according to Annex II, Ordinance on Hazardous Substances 4), with a symbol pursuant to Annex I, No.2, Ordinance on Hazardous Substances, or with the R-rates according to Annex I, No.3, Ordinance on Hazardous Substances, would not be required.
If the products under para.2 include substances with a content of > 0.1 weight per cent which are not listed in the publication according to Section 4a, para.1, Ordinance on Hazardous Substances, they shall be classified according the Section 4a, para.3, Ordinance on Hazardous Substances;

The products under para.2 must comply with the requirements set up by the construction supervising authority.

4 Compliance Verifications

The applicant shall declare compliance with the requirements pursuant to para. 3.1.
In addition, the applicant shall inform the
III 1.3
P.O.Box 330022
14191 Berlin

about the amounts of waste glass processed per year and used for the products marked with the Environmental Label.

The components of the product pursuant to para. 2 shall be given under their trade names and chemical designations in weight per cent for those under para. 3.1.1 or in per cent by volume for those under para. 3.1.2. The applicant shall submit Safety Data Sheets according to EC Directive 91/155/EEC.
For glass-wool products made from waste glass a test certificate shall be submitted proving that according to the current classification concept of TRGS 905 the fibres need not be classified as carcinogenic or suspected of causing cancer. Here, the criteria are:
