Substances not accepted for carriage

Chemically unstable substances of Class 8 shall not be accepted for carriage unless the necessary precautions have been taken to prevent the possibility of a dangerous decomposition or polymerization under normal conditions of carriage. For the precautions necessary to prevent polymerization, see special provision 386 of Chapter 3.3. To this end particular care shall be taken to ensure that receptacles and tanks do not contain any substances liable to promote these reactions.

The following substances shall not be accepted for carriage:


- chemically unstable mixtures of spent sulphuric acid;

- chemically unstable mixtures of nitrating acid or mixtures of residual sulphuric and nitric acids, not denitrated;

- perchloric acid aqueous solution with more than 72% pure acid, by mass, or mixtures of perchloric acid with any liquid other than water.

Lithium batteries shall meet the following requirements, except when otherwise provided for in ADR (e.g. for prototype batteries and small production runs under special provision 310 or damaged batteriesunderspecialprovision376).

NOTE:For UN 3536 LITHIUM BATTERIES INSTALLED IN CARGO TRANSPORT UNIT, see special provision 389 in Chapter 3.3.

Cells and batteries, cells and batteries contained in equipment, or cells and batteries packed with equipment, containing lithium in any form shall be assigned to UN Nos. 3090, 3091, 3480 or 3481 as appropriate. They may be carried under these entries if they meet the following provisions:

(a)Each cell or battery is of the type proved to meet the requirements of each test of the Manualof Testsand Criteria, Part III, sub-section38.3;

NOTE:Batteries shall be of atype proved to meet the testing requirements of theManual of TestsandCriteria, part III, sub-section 38.3, irrespective of whether the cells ofwhich they are composed are of a tested type.

(b)Each cell and battery incorporates a safety venting device or is designed to preclude a violentrupture under normal conditions of carriage;

(c)Each cell and battery is equipped with an effective means of preventing external shortcircuits;

(d)Each battery containing cells or series of cells connected in parallel is equipped with effectivemeans as necessary to prevent dangerous reverse current flow (e.g., diodes, fuses, etc.);

(e)Cells and batteries shall be manufactured under a quality management programme thatincludes:

(i)A description of the organizational structure and responsibilities of personnel withregard to design and product quality;

(ii)The relevant inspection and test, quality control, quality assurance, and processoperation instructions that will be used;

(iii)Process controls that should include relevant activities to prevent and detect internalshort circuit failure during manufacture of cells;

(iv)Quality records, such as inspection reports, test data, calibration data and certificates.Test data shall be kept and made available to the competent authority upon request;

(v)Management reviews to ensure the effective operation of the quality managementprogramme;

(vi)A process for control of documents and their revision;

(vii)A means for control of cells or batteries that are not conforming to the type tested asmentioned in (a) above;

(viii)Training programmes and qualification procedures for relevant personnel; and

(ix)Procedures to ensure that there is no damage to the final product.

NOTE:In house quality management programmes may be accepted. Third party certification is not required, but the procedures listed in (i) to (ix) above shall be properly recorded and traceable. A copy of the quality management programme shall be made available to the competent authority upon request.

(f)Lithium batteries, containing both primary lithium metal cells and rechargeable lithium ioncells, that are not designed to be externally charged (see special provision 387 of Chapter 3.3)shall meet the following conditions:

(i)The rechargeable lithium ion cells can only be charged from the primary lithium metalcells;
