Understanding Report of Analysis

Meaning of "< 3 MPN/g" and "< 10 CFU/g" in the report

“< 3 MPN/g” and “< 10 CFU/g” means that the เชื้อ is not detected. This is a standard reporting method for each unit.

Meaning of "< 0.3 MPN/g" in testing for Vibrio parahaemolyticus in frozen and salted food sample in the report

Standard test method specifies that samples of of products treated with frozen or salted process (chill excluded) require 10 times the amount of other samples. Therefore, when the xxxx is not detected, the result will state < 0.3 MPN/g.

Difference between per 0.01 g unit and per 0.1 g unit in microbial testing

0.1 g unit is ละเอียด more than 0.01 g unit. As the 0.1 g unit has a concentration of เนื้อตัวอย่าง at 0.1 g which is less than the 0.01 g unit that has a concentration of เนื้อตัวอย่าง at 0.01 g, therefore the 0.1 g unit can detect เชื้อ better/ได้ละเอียดกว่า 0.01 g unit.

Meaning of "Not Detected" and "< LOQ (Less than LOQ)" used in AMARC report of analysis

AMARC report of analysis complies with ISO/IEC 17025 for maximum benefits from the report. The utilized test method has been through validation process for accuracy. The necessary results reported are provided for international usability e.g.

Calibration

General

Accredited scope

Medical Devices

Medical devices maintenance

Medical devices and tools should be routinely check at least once a year similar to other tools and equipment. Maintenance will ensure readiness for usage.

Medical devices standard

General check-up includes external check through visual check, check for sound notification, and functioning display; measurement testing in the low, medium and high range to ensure that the measurement is within the tolerance; and issuing Certificate of Calibration. The standard used is by the Emergency Care Research Institute: ECRI.

Check up for infrequently-used devices

Devices that are not used frequently should also be checked and maintained to ensure measurement accuracy.

Device check up frequency

Devices that are used frequently should be checked and maintained more frequently than those infrequently used. Devices can thus be categorized by risk as:

  • High-risked devices
  • Medium-risked devices
  • Low-risked devices

Sign or symbol for calibrated medical devices

Our medical device team will attach a sticker indicating the calibration status, dates of current and next testing and maintenance, device code and report number for clients’ convenience.

Broken or malfunctioned devices

Preliminary, please inform the medical device maintenance team to examine the devices. Should any corrective measures cannot be applied, the devices should not be used and the need for a replacement might arise.

Inaccurate tools and devices

Some tools and devices require the accessories from the same brand of the tools and devices to be able to provide accurate measurement.

Accredited scope for medical devices

AMARC is ISO/IEC 17025 accredited for medical devices calibration in the following scope: mechanical and automated sphygmomanometers.

Electrical and Temperature Metrology

Tools and devices pick-up and delivery services

AMARC provides pick-up and delivery service for calibration items. Please contact our customer service for more information.

Thermometer with sensor or thermo-hygrometer - วิธีการประเมิน after receiving the calibration certificate

การประเมิน คือ ให้นำค่า Correction ± Uncertainty. For example, provided thatเกณฑ์ในที่นี้คือ ±1ºC (Correction + Uncertainty) = 0.2 + 0.39 = 0.59 ºC and (Correction – Uncertainty) = 0.2 – 0.39 = -0.19 ºC. ค่าที่ได้เมื่อรวมกันแล้วให้พิจารณาอยู่ในช่วง ± 1ºC คือ “ผ่าน” และหากผลการประเมินค่าแล้วไม่อยู่ในช่วง ±1ºC คือ “ไม่ผ่าน”

Thermometer with sensor or thermo-hygrometer - in case of not passing the calibration tolerance

Apply correction value by combining it with the measured result.

Thermo-hygrometer - calibration points

For room-temperature measurement, select 2-3 calibration points each for temperature and humidty to cover usage points.

Temperature chamber - in case of not passing the calibration tolerance

  • Consider if the tolerance is appropriate or not
  • Readjust or modify the device.

Temperature chamber - verification

It is recommened that thermometer with sensor with higher accuracy than that of the chamber be installed at the middle of the chamber.

Temperature chamber - วิธีการประเมินผลการสอบเทียบ

From the calibration result, use the measured temperature (ºC) at spread location #1, #2, #3, #4, #5, #6, #7, #8, #9 ± uncertainty; if the result of any location is within the tolerance, the result is “pass,” if the result exceeds the tolerance, the result is “not pass” and that point cannot be used. Inform the responsible and related personnel not to use the point.

For example, if measured temperature (ºC) at spread location ± uncertainty is within the tolerance, this result is “pass” and the point can be used. Given the tolerance 45 ±3ºC i.e. 45+3 = 48 and 45-3 = 42.

This means that the measured temperature (ºC) at spread location must be within 42 and 48. E.g. (location+uncertainty) = 45.30+1.02 = 46.32 ºC and (location-uncertainty) 45.30-1.02 = 44.28 ºC; the results are within 42 and 48, the results are “pass.

Temperature chamber - removal of objects from the chamber during calibration

Objects must be removed from the chamber as the objects hinder air circulation and absorb temperature causing the measurement to be inaccurate.

Temperature chamber - calibration point at near-room-temperature

Adjust the room temperature to be lower than the calibration temperature at least 5 ºC. For example, for the temperature calibration at 30 ºC, the room tempertature should be equal to or lower than 25 ºC.

Autoclave - water used

Distilled water or reverse osmosis water should be used to reduce limescale in the autoclave machine.

Choosing a calibration laboratory

Consider Calibration and Measurement Capability (CMC) of the calbration laboratory. The CMC should be within 1/3 of the tolerance.

Volumetric and Chemical Metrology

Volumetric glassware - การประเมินเกณฑ์เครื่องมือ upon receiving the Certificate of Calibration

Volumtric glassware usually have tolerance indicated on them. The sum of error and uncertainty must be within the tolerance. If the glassware do not have tolerance displayed, see the following standards: ASTM E287-ISO385 Burette, ASTM E969 Volume pipette, ISO1042 Flask, and ISO4788 Cylinder.

Volumetric glassware - usage in case of not passing the tolerance

Volumetric glassware that do not pass the tolerance can still be used by reclassing the glassware: from Class A to Class B and from Class B to usage that does not require high accuracy.

Volumetric glassware - calibration

The recommendation from การตรวจประเมินด้านวิชาการสำหรับห้องปฏิบัติการทดสอบด้านเคมีและที่เกี่ยวข้อง, Thai Industrial Standards Institute (TISI), is

  • Class A glassware – random at 10%
  • Class B glassware – 100%

Volumetric glassware - verification and intermediate check

Verifing or calibrating volumetric glassware using balance as standard. In choosing the standard, the accuracy must be more than the calibrated subject at least 3 to 10 times. E.g. flask with tolerance ± 0.1mL, the balance should have an accuracy of 0.01g or ค่าอ่านละเอียด 0.01g

Piston pipette, Dispenser, and Piston Burette - การประเมินเกณฑ์เครื่องมือเมื่อได้รับใบ Certificate of Calibration

ในการประเมินเครื่องมือเครื่องมือทั้ง 3 ชนิดนี้จะใช้เกณฑ์มาตรฐาน ISO/IEC 8655 ในการประเมินให้ดูค่า Systematic error และ Random error เทียบกับเกณฑ์ในตาราง ISO/IEC 8655

Piston pipette, Dispenser and Piston Burette - calibration volume

ISO/IEC 8655 requires calibration at 10%, 50% and 100% of nominal volume (e.g. if the volume is 10-100 µl, the nominal volume is 100 µl). Clients can also select the calibration points that are frequently used.

Piston pipette, Dispenser and Piston Burette - Preliminary remedy in case of piston pipette leakage

Aging tools and deviced could be due to deterioration from usage and misuage. Pipetting corrosive substances can cause O-ring deterioration, which should be replaced. Preventive maintenance should be performed at least every 6 months to ensure readiness for usage.

pH meter or conductivity meter - แล้วค่าที่วัดไม่นิ่ง

  • Electrode might not be clean or have oil stain at the tip of the probe. Clean electrode with electrode washing liquid or soaking in warm water for 30 minutes before trying again.
  • If ในการวัดค่าตัวอย่างแล้ว ค่าไม่นิ่งอ่านนานกว่าปกติ, leave the subject at room temperature until the result is คงที่ and remeasure. Temperature of the subject affects the pH and conductivity.

pH meter - changing electrode

Electrode of pH meter should be replaced if after the verification or calibration, the %Slope is less than 95% or more than 105% or the measurement does not match the buffer standard of the manufacturing specification.

pH meter - การประเมินเกณฑ์เครื่องมือเมื่อได้รับใบ Certificate of Calibration

Please see reference standard document for test method. If not, there is one reference for pharmaceutical teting which is USP; it indicates that after verfication or calibration, the result must be within ±0.05 pH and %slope 90-105 (2018 USPC Official 5/1/17 – 7/31/17 General Chapters: <791> pH).

Mechanical Metrology

Balance - calibration frequency

Balance should be calibrated at least once a year to ensure accuracy and adjust the balance in case of error.

Balance - suitable location and environment for installation

  1. Table and surface
    The table and surface for balance and balance stand must be stable and strong and must not vibrate or be magnetic. For example, marble or granite slab with a thickness at least 40 mm. Wood board should not be used for its risk of bending and metal board for its magnetic quality.
  2. Balance Room
    The balance room should situated in a non-vibrating location which could be from machine being operated or from traffic. The floor of the room should be smooth concrete surface without wood flooring and carpetry. There shouuld be no carpet, blinds and curtains as to reduce dust being accumulated as well as for cleaning convenience.

    • There should be only one entrance-exit to reduce windflow and dust.
    • Window should be minimal to reduce sunlight exposure and heat from outside.
    • If the room is air-conditioned, the airflow direction should be adjusted not to go to the balance.
    • The location of the balance should not receive direct sunligh as it will cause heat and results in measurement error. Lighting within the room also should be away from the balance to reduce the impact of heat from the light bulb.
  3. Temperature
    Temperature within the balance room should be stable. Any fluctuation or even gradual increase or decrease of temperatue during usage will cause an error of 1-2 ppm per celcius.
  4. Humidity
    The recommended humidity within the balance room should be between 45% to 60%. During usage, there should not be any sudden change that may impact the result of sensitive balance.
  5. Air
    Surrounding airflow is a hindrance to balance operation. Therefore, the balance should not be placed near air conditioner or a machine or devices with fan.
  6. Electric field and electro-magnetic field
    The intended location for electronic balance should be inspected for disturbance and error that may be stemmed from electric field and electro-magnetic field. User should be aware of signal disturbance from operation of devices within the nearby area such as electrical induction oven and switching on-off of machine, oven, incinerator or other devices that generate heat might create electrical signal through electric line within the area. Mobile phone and communication radio might also create signal disturbance and cause change in the measurement displayed.

Weight - standard for tolerance

Tolerance for weight refers to the internation standard OIML R111-1.

Weight - reference document for weight calibration

In calibrating weight, the reference document use is the internation standard OIML R111-1.

Weight - usage and maintenance

  • Standard weights should be kept in box or container made from wood or plastic to protect the standard weights from dust and humidity. Standard weights should be kept in dense electro-magnetic field.
  • Standard weights should be kept clean. They must not be touched bare-handed; use pick-up tools, gloves and forceps in handling the weights. The point touching the weights should be made from or covered with materials that do not scratch or damage the weights such as plastic, leather or cotton.
  • Be careful not to drop the standard weights.
  • Surface for placing the standard weights on must be clean, smooth or soft to product the weight from dirt or scratch.
  • To prevent the standard weights from wearing, in moving standard weights on the plate, use pick-up and place-down movement. Do not drag or slide.
