2) Testing personnel: familiar with the requirements of the testing items they are responsible for, familiar with the operation, and obtain the employment certificate after training. Each test project has at least two inspectors, who can work part-time between different test projects.

Second, laboratory accreditation requirements for environmental conditions of facilities

1, the environmental conditions of the facility must meet the specified requirements.

Different testing/calibration projects have different requirements for environmental conditions. According to Article 5.3.2 of the Accreditation Criteria, "the laboratory shall monitor, control and record the environmental conditions when required by relevant specifications, methods and procedures, or when the quality of the results is affected."

For the detection/calibration items sensitive to environmental conditions, the laboratory must meet the relevant requirements, and monitor, control and record them. For example, in the textile testing laboratory, when testing physical indicators (such as strength, elongation, twist, fineness, electrostatic capacity of anti-woven materials, etc.), environmental conditions must meet the standards. ), and must be equipped with automatic temperature recorder (or automatic temperature and humidity monitoring device) in the detection area, and must keep continuous monitoring records during work.

The laboratory does not need to monitor, control and record the testing items that have no special requirements for environmental conditions. For example, in the gold and jewelry testing laboratory, some instruments and methods have no special requirements for the environment.

2. Control the access and use of the detection/calibration area.

In order to obtain correct detection/calibration results, the laboratory must effectively control the access and use of detection/calibration areas. Specific measures and methods are as follows:

1) divide the laboratory area by function.

Different jobs have different environmental requirements, so the implementation room area should be divided and marked. The laboratory can be divided into office area, detection/calibration area, maintenance area, scientific research area and reception area according to its functions. According to the detection requirements, the detection/calibration area can be divided into high temperature and high humidity stable operation area, high pressure operation area, ultra-clean operation area and aseptic operation area.

2) Control of personnel access

Foreign personnel should be approved to enter the laboratory. In order to avoid abnormal interference, the personnel in the laboratory should also be controlled to limit the entry of unauthorized personnel. Therefore, some laboratories adopt automatic identification access control system. Otherwise, a warning sign of "Do not disturb while working" should be set for the room where the temperature and humidity fluctuation will affect the detection/calibration results due to personnel's entry and exit. If there are sanitary requirements, the personnel entering the laboratory shall be disinfected or other purification measures shall be taken.

3) Control the experimental area or use. For example, work unrelated to detection/calibration is not allowed in the calibration/testing area, and technical consultation by outsiders is not allowed. In some areas of the calibration laboratory (such as scales, measuring blocks and weights), water is not allowed because the relative humidity is less than 60%; Cell phones are not allowed in the magnetic calibration area.

Three, laboratory accreditation requirements for equipment

1, equipment requirements

The laboratory shall be equipped with all equipment (including self-owned, leased and customer-provided equipment) required for correct testing/calibration. The technical indicators and functions of the equipment used (including sampling, sample preparation, data processing and analysis) shall meet the requirements. When using equipment other than fixed control (including on-site inspection/calibration), relevant additional procedures shall be followed to ensure that the quality of final inspection/calibration results meets the requirements of this specification.

2, equipment calibration requirements

Number or value of key equipment (such as measuring range, accuracy level/maximum tolerance, offset resistance, repeatability, drift, resolution, etc.). ) have an impact on the test/calibration results, calibration shall be carried out and a calibration plan shall be made. OIML divides metrological verification into two forms: first verification and subsequent verification. The former is to judge whether the equipment fully meets the specified requirements; The latter is to determine whether the equipment maintains the main metering characteristics. This article also stipulates that the equipment shall be calibrated or verified before it is put into operation (that is, used for the first time); But it should be checked or calibrated before each use. The equipment shall be used within the validity period of calibration/verification.

3. Authorization requirements

All equipment, especially important equipment, should be operated by designated operators, who should be trained and hold operation certificates. The work instructions on the use and maintenance of the equipment (including the technical specifications or related manuals provided by the manufacturer) shall be effective for the convenience of relevant personnel and to ensure that the equipment is in good working condition.

4. Equipment identification management

Each equipment and its software that have an impact on the results shall be uniquely identified as far as possible, such as the equipment management number;

5, equipment files

The laboratory should establish the main equipment files that have an important impact on the results. Usually, a file is created in the form of a file. For many small measuring instruments of the same kind, it is possible to establish a measuring tool ledger, establish a file and centrally store relevant information. Equipment technical archives generally include the following basic information

Equipment registration form, such as equipment name, software name, manufacturer name, management number, specifications and models, factory number, records of equipment using department, storage location and other unique identifiers;

Product certificate;

Original instruction (if it is in a foreign language, it should be translated);

Documents such as installation and debugging records in the acceptance process;

Operating procedures, self-calibration procedures and periodic verification procedures;

Calibration certificate (or metrological verification certificate, test certificate and self-calibration report);

Used "Equipment Usage Record Form"

Equipment maintenance and repair records;

Other information related to the equipment.

6, equipment management program

Including the requirements for safe disposal, transportation, storage, use and maintenance of equipment. Laboratories should formulate equipment maintenance and management procedures, and earnestly implement them to ensure the good performance and normal function of equipment. Some routine maintenance work not only helps to prevent equipment failure, but also reduces the risk of instrument performance exceeding tolerance.

7. Management requirements for unqualified equipment

This requirement clarifies three issues; One is what unqualified equipment is, the other is how to deal with unqualified equipment, and the third is to trace the influence caused by previous testing/calibration after discovering unqualified equipment. It should be pointed out that the defects of equipment are not only the current problems, but also various subtle influences, which make the equipment change from quantitative to qualitative. The current defect is the accumulation of past problems. It is necessary to control the quality of equipment with technology, find out the trend of equipment deviation in time and take preventive measures. If there is no daily quality control, it is necessary to trace back, evaluate the impact of equipment defects on customers, and even inform customers.

8. Management requirements for equipment calibration status marks

The scope and content of calibration status identification are defined. The guide does not specify what signs to use. For example, three marks can be used to indicate qualified (green), allowed (yellow) and disabled (red), and five marks can be used to indicate qualified, allowed, restricted, disabled and sealed. Some equipment that is not directly related to the output data, such as regulated power supply, air conditioner, transformer, etc. , has normal function, so it is not appropriate to post a yellow card; Generally, green cards are labeled as "unmeasurable" to show the difference, and some are directly labeled as "normal function".

9. Requirements for indirect control equipment.

For example, if the equipment is borrowed, on-site inspection/calibration will be carried out. After the equipment is returned, its function and calibration status must be checked before continuing to use, and it can only be used after it is proved to be satisfactory.

10, requirements for "periodic verification" of equipment

Verification standard is a relatively stable instrument, product or other object used to represent the tested object. Its measuring range and precision level should be close to the measured object, but its stability is better than the actual measured object. It should be pointed out that not all devices need to be inspected during the period, only those devices with large drift rate and very frequent use need to be inspected. So for equipment, this requirement is not mandatory, and the terms are also carried out "when necessary". However, the laboratory should formulate a "periodic verification regulation", list it and implement it according to the requirements of the plan and regulation.

1 1, equipment protection requirements

This clause applies to devices with adjustment functions, such as instruments with one or more potentiometers, variable capacitors or other similar elements, which may affect one or more calibration points of the instrument. When a checkpoint is found to be out of tolerance or very close to tolerance during calibration, it is usually necessary to adjust these regulators to return to normal. At this time, the laboratory should take measures to prevent the random adjustment of equipment (including hardware and software) from affecting the validity of the measurement results.
