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);
General Norm for Pattern Evaluation
of Measuring Instruments
1 Scope
This Norm is applicable to pattern evaluation of measuring instruments and
approved pattern’s compliance examination.
2 Normative references
This Norm takes the following documents as reference.
JJF 1016-2014 The Rules for Drafting Program of Pattern Evaluation of
Measuring Instruments;
JJF 1051 Designation and Classification Code for Measuring Instruments;
JJF 1069 Rules for the Examination of the Service of Legal Metrological
Verification.
For dated references, only the edition cited applies. For undated references,
the latest edition of the referenced document (including any amendments)
applies.
3 Terms and definitions
Terms and definitions defined by JJF 1001 "General Terms in Metrology and
Their Definitions" AND the following terms and definitions are applicable to this
Norm.
3.1 Measuring instrument
The single device or combination with one or multiple auxiliary equipment,
which are used for measuring.
3.2 Type (pattern) evaluation
The systematical examination and test on performance of one or multiple
samples in specified pattern according to document requirements on measuring
instruments, of which the results are written in the pattern evaluation report to
confirm if the pattern can be approved.
Note. The pattern of measuring instruments refers to the prototype as well as its technical
information (e.g., drawings, design material, software documents, etc.) of a certain
measuring instrument.
3.3 Single product
The product of one specification or model.
3.4 Series product
A group of products with same measuring principle, same or similar structure
(appearance), which meet one of the following conditions.
1) With same accuracy but with different measurement interval;
2) With different accuracy but with same measuring interval and structure.
4 Technical information and test prototype that shall
be submitted by the application organization
The applicant shall provide the technical information and test prototype required
by pattern evaluation to the technical agency who undertakes the pattern
evaluation.
4.1 Technical information
The following technical information shall be provided in two-sets by the
applicant.
- "Application for Pattern Approval of Measuring Instruments" accepted and
entrusted by the government metrological administrative department;
- Product standard;
- Assembly diagram, circuit diagram and critical part list;
- Instructions for use;
- Test report made by manufacturer or technical agency;
- Explosion-proof certificate shall be provided if the test is carried out in the
explosive environment;
- Software evaluation report (if the government metrological administrative
Carry out the stability test according to provisions of the pattern evaluation
outline.
5.4.7.1 Carry out the test of measuring performance under reference conditions.
5.4.7.2 Carry out the operation test. According to provisions of the pattern
evaluation outline, operate for sufficient time or cumulants. Adjustments or
changes are not allowed during prototype operation.
5.4.7.3 After the operation test is completed, carry out the test of measuring
performance under reference conditions; check if the data changes of two tests
comply with the requirements of the pattern evaluation outline.
5.5 Determination of pattern evaluation result
5.5.1 It is qualified when all the evaluation items of the prototype comply with
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 are 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 are 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
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
