BS EN 14266:2003 – Derivatives from coal pyrolysis — Coal tar and pitch based binders and related products: coating tar — Characteristics and test methods
1 Scope
This European Standard specifies the methods of test required to determine the characteristics for “coating tar” used for coating.
Depending on the required application and the desired properties of the end product, different grades of coating tars are available.
2 Normative references
This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text, and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European
Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies (including amendments).

3 Terms and definitions
For the purposes of this European Standard, the terms and definitions given in EN 13847:2001 apply.
4 Classification
For the purposes of this European Standard, the classification according to EN 13847:2001 applies.
5 Characteristics
The following characteristics shall be determined:
a) Distillation;
b) Viscosity;
c) Water content.
6 Specifications
The typical values given in annex A can be used as requirements.
7 Sampling
ISO 6257 specifies methods for sampling and preparing samples for testing of coating tar.
These methods are applicable to all grades of coating tars in liquid form, in bulk, or in a numbers of containers making up one batch at sites of manufacture, storage of delivery.
8 Test methods
For the determination of the characteristics according to clause 5, the methods listed in table 1 have to be used.
