Foreword
The International Organization of Legal Metrology (OIML) is a worldwide, intergovernmental organization whose primary aim is to harmonize the regulations and metrological controls applied by the national metrological services, or related organizations, of its Member States. The main categories of OIML publications are:
International Recommendations (OIML R), which are model regulations that establish the
metrological characteristics required of certain measuring instruments and which specify methods and equipment for checking their conformity. OIML Member States shall implement these Recommendations to the greatest possible extent; International Documents (OIML D), which are informative in nature and which are intended to
harmonize and improve work in the field of legal metrology; International Guides (OIML G), which are also informative in nature and which are intended to
give guidelines for the application of certain requirements to legal metrology; and International Basic Publications (OIML B), which define the operating rules of the various OIML
structures and systems. OIML Draft Recommendations, Documents and Guides are developed by Technical Committees or Subcommittees which comprise representatives from the Member States. Certain international and regional institutions also participate on a consultation basis. Cooperative agreements have been established between the OIML and certain institutions, such as ISO and the IEC, with the objective of avoiding contradictory requirements. Consequently, manufacturers and users of measuring instruments, test laboratories, etc. may simultaneously apply OIML publications and those of other institutions.
International Recommendations, Documents, Guides and Basic Publications are published in English (E) and translated into French (F) and are subject to periodic revision.
Additionally, the OIML publishes or participates in the publication of Vocabularies (OIML V) and periodically commissions legal metrology experts to write Expert Reports (OIML E). Expert Reports are intended to provide information and advice, and are written solely from the viewpoint of their author, without the involvement of a Technical Committee or Subcommittee, nor that of the International Committee of Legal Metrology. Thus, they do not necessarily represent the views of the OIML.
This publication – reference OIML R 76-2, Edition 2007 – was developed by Technical Subcommittee TC 9/SC 1 Non-automatic weighing instruments. It was approved for final publication by the International Committee of Legal Metrology in 2007 and supersedes the previous edition of R 76-2 (1993).
OIML Publications may be downloaded from the OIML web site in the form of PDF files.

OIML R 76-2: 2007 (E)
Introduction
The “Type evaluation report”, the subject of R 76-2, aims at presenting, in a standardized format, the results of the various tests to which a type of a non-automatic weighing instrument shall be submitted with a view to its approval. These tests are described in Annexes A and B of R 76-1.
All metrology services or laboratories evaluating types of non-automatic weighing instruments according to R 76-1 or to national or regional regulations based on OIML R 76-1 are strongly advised to use this “Type evaluation report”, directly or after translation into a language other than English or French. Its direct use in English or in French, or in both languages, is even more strongly recommended whenever test results may be transmitted by the country performing these tests to the approving authorities of another country, under bi- or multi-lateral co-operation agreements. In the framework of the OIML Certificate System for Measuring Instruments, and the OIML Mutual Acceptance Arrangement (MAA), use of this report format is mandatory, in French and/or in English with translation into the national languages of the countries issuing such certificates, if appropriate.
The “information concerning the test equipment used for type evaluation” shall cover all test equipment which has been used in determining the test results given in a report. The information may be a short list containing only essential data (name, type, reference number for purpose of traceability). For example:
Verification standards (accuracy, or accuracy class, and no.);
Simulator for testing of modules (name, type, traceability and no.); Climatic test and static temperature chamber (name, type and no.); Electrical tests, bursts (name of the instrument, type and no.);
Description of the procedure of field calibration for the test of immunity to radiated electromagnetic fields.
Note concerning the numbering of the following pages
In addition to a sequential numbering: “R 76-2 page .....” at the bottom of the pages of this publication, a special place is left at the top of each page (starting with the following page) for numbering the pages of reports established following this model; in particular, some tests (e.g. weighing performance) shall be repeated several times, each test being reported individually on a separate page following the relevant format; in the same way, a multiple range instrument shall be tested separately for each range and a separate form (including the general information form) shall be filled out for each range. For a given report, it is advisable to complete the sequential numbering of each page by the indication of the total number of pages of the report.

PASSED X – For each test, the “SUMMARY OF TYPE EVALUATION” and the =“CHECKLIST” shall be completed according to this example: ===when the instrument has passed the test: =when the instrument has failed the test: when the test is not applicable: FAILED X – The white spaces in boxes in the headings of the report should always be filled in according to the following example: At start At max At end 21.2 °C Temp.: 20.5 Rel. h.: % Time: Bar. pres.: hPa where: Temp. temperature Rel. h. = relative humidity Bar. pres. = barometric pressure (barometric pressure is necessary for the span stability test and when specified by IEC test provisions; in other cases it may be necessary only for class I instruments). “Date” in the test report refers to the date on which the test was performed. In the disturbance tests (12.1 through 12.7), faults greater than e are acceptable provided that they are detected and acted upon, or that they result from circumstances such that these faults shall not be considered as significant (see T.5.5.6 in R 76-1); an appropriate explanation shall be given in the column “Yes (remarks)”. Numbers in brackets refer to the corresponding subclauses of OIML R 76-1. 5

CHECKLIST
This checklist has been developed based on the following principles:
to include requirements that cannot be tested according to tests 1 through 15 above, but that shall be checked experimentally, e.g. the operating range of the tare device (4.6.4), or visually, e.g. the descriptive markings (7.1);
to include requirements which indicate prohibitions of some functions, e.g. automatic tare device for instruments for direct sales to the public (4.13.3.3);
to include neither general requirements, e.g. suitability for use (4.1.1.2), nor weights and verification devices, e.g. auxiliary verification devices (4.9);
not to include requirements that allow functions or devices to be used, e.g. a combined semi-automatic zero-setting and tare device operated by the same key (4.5.4).
This checklist is intended to serve as a summary of the results of examinations to be performed and not as a procedure. The items on this checklist are provided to recall the requirements specified in R 76-1, and they shall not be considered as a substitution to these requirements.
As for non-self-indicating instruments, clause 6 of R 76-1 shall be followed in lieu of this checklist.
The requirements that are not included in this type evaluation report (tests 1-15 and checklist 17) are considered to be globally covered by the type approval or OIML Certificate (e.g. classification criteria [3.2 and 3.3], suitability for application, use and verification [4.1.1.1, 4.1.1.2 and 4.1.1.3]).
For non-mandatory devices, the checklist provides space to indicate whether or not the device exists and, if appropriate, its type. A cross in the box for “existent” indicates that the device exists and that it complies with the definition given in the terminology. When indicating that a device is non-existent, also check the boxes to indicate that the tests are not applicable (see page 5).
If appropriate, the results stated in this checklist may be supplemented by remarks given on additional pages.
