The mission of the JRC is to provide customer-driven scienti� c and technical support for the conception, development, implementation and monitoring of EU policies. As a service of the European Commission, the JRC functions as a reference centre of science and technology for the Union. Close to the policy-making process, it serves the common interest of the Member States, while being independent of special interests, whether private or national.

PREFACE
This Catalogue lists certified isotopic reference materials (IRMs) currently available or in preparation at the Joint Research Centre - Institute for Reference Materials and Measurements (IRMM) (1959-1992: Central Bureau for Nuclear Measurements - CBNM). All of these Reference Materials have a certificate issued under the responsibility of IRMM, Isotope Measurements unit. Some of them have been examined by a nuclear experts committee because of their use in nuclear safeguards and are certified as EC-NRM’s (European Community - Nuclear Reference Materials).
The IRMs listed can be divided into two major groups:
− those certified for isotope amount ratios and hence suitable for calibration of measurements of isotope abundance ratios
− those certified for isotope amount content and hence suitable for direct use in isotope dilution as “spikes” against which an unknown amount of an isotope or an element can be measured.
These IRMs are also suitable for
− calibration of instruments for isotopic measurements
− calibration and evaluation of isotopic measurement procedures
− development of isotopic measurement methods
− nuclear material accountancy measurements
The IRMs are available to industrial and official laboratories, as well as to academic and research institutes or other users. As far as orders for nuclear materials from countries outside the EU are concerned, individual authorisation for delivery is required from the European Commission.
Each IRM is described by a number, matrix type and certified quantities and their values with their uncertainties. All uncertainties indicated are ISO/BIPM expanded standard uncertainties U = k·uc where uc is the combined uncertainty. They are given in parentheses and include a coverage factor k=2. They apply to the last digit(s) of the value. The uncertainties are evaluated from the ISO/BIPM Guide to Expression of Uncertainty in Measurement onwards.
All information given in this catalogue is indicative and does not replace the certificates issued for each IRM.
Each IRM unit delivered is accompanied by a certificate containing the following information: the certified quantities and value(s), the certified uncertainty assigned to each certified value, date of issue and a short indication of the scientific approach used to measure each certified quantity.
New certificates are issued when new isotopic reference materials or replacements are prepared or when existing isotopic reference materials are re-certified to smaller uncertainties.
5
A replacement for a given Isotopic Reference Material is selected such as to have approximately the same value for the certified characteristic as its predecessor. It is identified by a character after the Isotopic Reference Material number (e.g. IRMM-023A).
All values of the JRC-IRMM Isotopic Reference Materials are traceable to the SI (the international system of base quantities and base units). Isotopic measurement results corrected by means of these isotope ratio reference materials will have reduced (ISO/BIPM) uncertainties. Amount content measurements carried out using these spike reference materials will be traceable to the SI, if carried out properly.
This catalogue also lists isotopic certification measurement services (available to a limited extent), consulting services in matters of isotopes as well as in Traceability to the SI and metrology in chemistry.
It announces training possibilities through the Isotopic Measurement Training and Education Centre, IMTEC and information on isotopes through the Isotopic Data and Information Centre, ISDIC.
It has been prepared for the benefit of isotopic measurements in the European Union and elsewhere.

EUROPEAN COMMISSION JOINT RESEARCH CENTRE Institute for Reference Materials and Measurements
TERMS AND CONDITIONS
Governing the Sales Contracts of the IRMM-JRC Geel
All sales contracts between the IRMM, Directorate General Joint Research Centre of the European Commission, hereinafter to be referred to as “the Seller” and its clients, hereinafter to be referred to as “the Buyer” shall be governed by and processed in accordance with the following terms and conditions. Acceptance of Seller’s quotation by Buyer automatically implies acceptance by Buyer of Seller’s Terms and Conditions. 1. Unless stated otherwise on the quotation, materials and services shall be
furnished at prices and service fees fixed by the Seller, in effect on the date of shipment of materials or performance of the services. Where no specific prices are in effect, materials and services shall be furnished at prices and service fees calculated by the IRMM. The Seller’s decision in these matters is final. Prices in catalogues issued by the Seller are subject to change without notice.
2. Subject to applicable regulations, Seller shall ship all materials covered by this
order “Free Carrier Geel, Belgium” (FCA), normally by certified parcel post. Postage will be billed at cost and itemised on the invoice. Under this term it is understood that Seller shall have fulfilled his obligation to deliver when he has handed over the materials, cleared for export, into the charge of the carrier named by the Buyer or appointed by the Seller on behalf and at the expense of the Buyer.
3. Materials that, due to regulations or for any other practical reason, cannot be sent
by certified parcel post shall be delivered “Ex Works Geel, Belgium”, (EXW). Under this term the Seller fulfills his obligation to deliver when he has made the materials available at his premises. The Buyer bears all costs and risks of loss of or damage to the goods, involved in taking the materials from the seller’s premises to the desired destination.
4. If necessary, the Seller, at the Buyer’s request, risk and expense, may provide
assistance in obtaining any export licence or other official authorisation necessary for the exportation of the materials.
5. It will be the Buyer’s responsibility to designate an experienced carrier as an
intermediate consignee for the shipment. This carrier will collect the materials from the Sellers facilities in Geel, Belgium. Shipping carriers and modes of shipment must fully comply with international and Belgian transportation regulations in effect at the time of shipment.
44
6. Responsibility for loss of or damage to materials sold under this order shall pass to the Buyer when such materials have been handed over into the charge of the carrier named by the Buyer or appointed by the Seller on behalf and at the expense of the Buyer.
7. Buyer shall advise Seller of having taken delivery by means of the Confirmation of
Delivery form, a specimen is attached. This form is to be returned to Seller by mail or fax within six weeks after delivery. In the event that the form is not returned, Seller shall have the right to assume that Buyer has taken delivery.
8. Unless a prepayment is agreed, Seller shall establish the invoice concerned and
forward it to the Buyer upon receipt of the Confirmation of Delivery form from Buyer. Payment shall be made by bank transfer in EURO according to the following general payment terms of the European Commission:
i) Invoice payable after 45 days, in the event of non-payment by the due date, interest will be payable on the established entitlement at the European Central Bank rate + 3.5 points ii) All bank charges are for the account of the customer iii) Where the other party has claims on the Commission that are certain, of a fixed amount and due, the Commission reserves the right, after giving prior notification , to effect recovery by offsetting. iv) Failing payment by the due date, the Commission reserves the right
- to call in any financial guarantee lodged in advance - to enforce payment under Article 256 of the EC Treaty
