Foreword
JJF 1015-2014 "General Norm for Pattern Evaluation of Measuring
Instruments" is a guiding technical specification for pattern evaluation of
measuring instruments.
JJF 1015-2014 "General Norm for Pattern Evaluation of Measuring
Instruments" was modified on the basis of JJF 1015-2002 "General Norm for
Pattern Evaluation and Pattern Approval of Measuring Instruments", which
references to partial contents of No.19 "Pattern evaluation and pattern
approval" of International Organization for Legal Metrology (OIML) and
combines with the relevant requirements proposed by the metrological
administrative department.
Compared with JJF 1015-2002, this Norm is only related to the pattern
evaluation of the measuring instruments. The pattern approval shall be
specified by relevant documents issued by the metrological administrative
department. The main changes of this revision are as follows:
- Add terms "single product" and "series product" ( see 3.3 and 3.4 );
- Add "Application for Pattern Approval of Measuring Instruments that was
accepted and entrusted by the government metrological administrative
department" in the submitted technical information (see 4.1);
- Make significant change in the submitted test prototype (see 4.2);
- Improve the approved pattern or specify the basis-change of the previous
pattern evaluation (see 5.1);
- Refine the examination of technical information to make it more operatable
(see 5.2);
- Divide the pattern evaluation into observation project and test project, so
as easy for description (see 5.3 and 5.4);
- Add "function verification" (see 5.4.1);
- Refine "stability test" (see 5.4.7);
- Change the way of "determination of pattern evaluation result"; it shall be
determined as qualified only when all the items for evaluation are qualified
(see 5.5);
- Enrich the "pattern evaluation report" by requiring records and photos to be
listed in the report as attachment (see 5.6);
- Change the handling of test prototype (see 6);
- Refine the "notices" of "pattern evaluation report" and specify 15-day
appeal period (see Appendix A);
- Add tables of "measurement parameters for measuring instruments",
"critical parts and materials", "list of equipment for pattern evaluation" and
"list of evaluation items and evaluation results";
- Delete contents relating to pattern approval;
- Delete basic safety test;
- Delete tests for adaptability of measuring performance in transport
simulation and retention simulation;
- Delete "handling for the first test failure".
The previous versions of this Norm are:
- JJF 1015-2002;
- JJF 1015-1990.

the requirements of the pattern evaluation outline.
5.5.2 For single product, it shall be determined as unqualified if one or more
items are unqualified.
5.5.3 For series product, according to 5.5.2, this series shall be determined as
unqualified if one or more models are unqualified.
5.6 Issue of pattern evaluation report
After tests are completed, issue the pattern evaluation report according to the
format requirements in Appendix A. Reports shall be respectively issued for
series products with different measuring performance.
For qualified product, "The test prototype complies with requirements of pattern
evaluation outline, and it is suggested that the pattern of measuring instruments
of the following models is approved: ×××× and ××××" shall be indicated in
"Pattern evaluation conclusion and suggestion" of pattern evaluation report.
For unqualified product, "The ×××× of the test prototype fails to meet
requirements of ×××× pattern evaluation outline, and it is suggested that the
pattern of measuring instruments of the following models is not approved: ××××
and ××××" shall be indicated in "Pattern evaluation conclusion and suggestion"
of pattern evaluation report.
Retaining method and retaining quantity of the prototype shall be indicated in
"Other notes" in the 8th part of the report.
The pattern evaluation report is composed of three parts: main body,
attachment 1 and attachment 2. The format of main body is shown in Appendix
A. The main body shall contain information related to the applied measuring
instrument pattern, as well as conclusion and suggestion drawn from
attachment 1. Attachment 1 is the record of objective circumstances observed
and measured by the reviewer during pattern evaluation, of which the format is
consistent with the record format of referenced pattern evaluation outline. If
there are more than one test prototypes, the reports shall be respectively stated
as attachment 1-1, attachment 1-2 to attachment 1-n. Attachment 2 contains
photos (shall not be less than 4) taken by the technical agency after the pattern
evaluation is completed, and the mark is pasted on the prototype. This group of
photos shall include the overall shape, internal structure, display section, critical
components of the prototype. Page numbers shall be noted in the page footer
of the report as "page × of ×".

JJF 1016-2014's Appendix A. The format of test item is same as the one of test
record specified by pattern evaluation outline of this measuring instrument.
5.7 Handling of unqualified pattern evaluation
When the audited technical information is found non-conformance, it shall
inform the applicant to conduct rectification.
When there is unqualified item in the test, if the conditions of prototype permit,
the technical agency shall proceed the test till all test is completed. Otherwise,
the technical agency shall stop if the test is unable to be continued due to
unqualified item of prototype.
5.8 Confidentiality of prototype and technical information
The technical agency shall keep the prototype, technical information and
evaluation results confidential according to requirements of JJF 1069 during
pattern evaluation and after pattern evaluation.
6 Handling of test prototype
6.1 Handling of qualified prototype
6.1.1 Seal and mark of prototype

effective seal and mark to the qualified prototype or critical components. The
mark shall be obviously pasted and the mark format is shown in Appendix B.
The seal and mark shall ensure the critical components and material of the
prototype shall not be replaced or adjusted. The technical agency who
undertakes the pattern evaluation shall take photos of well-sealed and marked
prototype. Characters on the mark shall be clearly shown in the photos. Photos
are listed in the attachment 2 of the pattern evaluation report.
6.1.2 Prototype retention
In order to meet requirements for compliance examination of approved pattern,
the technical agency who undertakes the pattern evaluation shall hand over the
sealed and marked test prototype to the applicant. The applicant shall well store
the sealed and marked test prototype till the fifth year after the production of
this pattern of measuring instrument is stopped.
