GMP车间/设备上的显示时间,误差标准是多少?

嘉峪检测网 2025-04-28 12:46

导读:本文介绍了GMP车间/设备上的显示时间误差标准是多少。

有公司规定:

 

1. 生产车间用于记时的时钟在初次使用之前应由计量室依据广播电台的整点报时信息校对并调准,然后贴上校验标签。

2. 时钟应悬挂在车间操作人员易于读数的地方,并且罩上玻璃罩。

3. 生产车间由车间计量员每周对时钟的准确性校对两次,两次较对应在同一天的上午和下午各一次。

4. 当需要对时钟校对时,车间计量员将时钟拿到计量室,打开收音机,听广播电台的整点报时并校对时钟,同时填写时钟校对记录,计量室管理员复核。

5. 使用部门如发现时钟不能正常运行,应及时通知计量室安排维修,维修后需经过重新校对。

6. 时钟校准误差不应超过±5分钟

 

在国外,也有制药公司在SOP中规定如下:

 

Procedure

校准程序

 

The user department shall collect the master clock to verify the equipment and instrument clocks, and other clocks under the scope of this SOP. Before the use of a master clock to verify other clocks, the master clock must have to be verified for its accuracy. This verification shall be done as per the frequency defined in the procedure.

 

使用部门应收集主时钟(标准时间),以确认设备和仪器时钟,以及本 SOP 范围内的其他时钟。在使用主时钟(标准时间)确认其他时钟之前,必须确认主时钟的准确性。此确认应根据程序中定义的频率进行。

 

Master clock shall be verified and adjusted with central server clock (connected with world clock) with the help of IT personnel on the day of verification of clocks. The Master clock shall have a unique identification number.

 

在主时钟校准时,应在 IT 人员的帮助下,使用中央服务时钟(与世界时钟对接)对主时钟进行校准和调整。主时钟应具有唯一的标识号。

 

Verification of the master clock shall be managed by the engineering department. The record shall be maintained for this verification and harmonization if any.

 

主时钟的确认应由工程部门管理。确认和校正(如有)过程应有记录。

 

After completion of master clock verification and time harmonization, hand over the clock to the user department for clock verification.

 

完成主时钟确认和时间校正后,将时钟交给使用部门进行时钟确认。

 

User department shall verify the timing of departmental clocks and record for the same shall be maintained.

 

使用部门应确认部门时钟的时间,并保留相同的记录。

 

In case of time difference observed more than 30 seconds, it shall be harmonized with the help of the engineering/ IT department. Record for the adjustment shall be maintained.

 

如发现时间误差超过 30 秒,则应在工程/IT 部门的帮助下进行校正。应保留校正记录。

 

Clock verification shall also be done in case of any maintenance done on the equipment where the clock is maintained and maintenance may have a potential impact on the computerized controls. For example, equipment PC, HMIs (Human Machine Interface), instruments, etc.

 

如对具有时间显示的设备进行任何维护,并且维护可能会对计算机控制产生潜在影响,也应进行时间验证。例如,设备 PC、HMI(人机界面)、仪器等。

 

After completion of maintenance activity, the system should be verified using the master clock by the engineering and user department.

 

维护活动完成后,工程和使用部门应使用主时钟对系统进行确认。

 

While verification of the above clocks if required, time harmonization may need to be done. The harmonization should be done as directed in the following table.

 

如需要,在验证上述时钟的同时,可能需要进行时间调校。调校工作应按照下表进行。

  • Noted Gap between the master clock and   clock under verification

    主时钟与被校准时钟之间的偏差

    Required action

    采取措施

    Less than or equal to 30 seconds

    小于或等于30秒

    No action required

    无需措施

    31 seconds to 120 seconds

    31 秒到 120 秒

    Time adjustment as per master clock

    根据主时钟校正时间

    More than 120 seconds

    超过 120 秒

    Non-conformance and investigation to   understand the impact of an occurrence.  Corrective Action and   Preventive Actions to eliminate the root cause and other potential areas with   similar possibilities.

    不合格并调查,以了解事件的影响。 纠正措施和预防措施,以消除根本原因和其他具有类似可能性的潜在区域。

  •  

    After completion of the clock verification activity, the master clock shall be re-verified against the central server timing.

     

    完成时间确认活动后,应根据中央服务时间重新确认主时钟。

     

    Clock timing shall be adjusted in the format, HH:MM: SS in 24 Hour format. In case of this format is not possible in any of the equipment/systems, it shall be adjusted as per the applicable setting for the clock.

     

    时钟应以 24 小时格式的 HH:MM: SS 进行调整。如果任何设备/系统无法采用这种格式,则应根据时钟的适用设置进行调整。

     

    Frequency

     

    频率

     

    Equipment, instrument and digital clocks (Non GPS) – Monthly

     

    设备、仪器和数字时钟(非 GPS)– 每月

     

    GPS clock, server connected clock and computerized systems – Six monthly

     

    GPS 时钟、服务器连接时钟和计算机化系统 – 六个月

     

    Master clocks used for verification – before and after verification of other clocks

     

    主时钟 – 确认其他时钟之前和之后

     

    JJF2199 - 2025 数字式时钟校准规范

     

    近日,全国时间频率计量技术委员会发布了JJF2199 - 2025 数字式时钟校准规范,适用于数字式时钟的校准,也适用于其他以数字形式显示时间信息装置的校准。其中对数字式时钟的校准作了如下规定:

     

    显示时刻误差:

    复校时间:建议复校时间间隔为 12 个月
