Calibration and ISO standards post will help you about calibration requirements in ISO Standards for ISO Certification on various standards. Specially for management system standard ie ISO 9001; it is mandatory to do calibration.
ISO 9001:2015 Clause 220.127.116.11
Calibration for monitoring devices is very important to get accurate reading from the machine, equipment, tools and devices. In the clause 18.104.22.168 of ISO 9001 it is written about the calibration of monitoring devices or tools. Now it is a question which tools should be calibrated? Actually it depends on factory activities. However most common measuring tools like measurement tape, light box, slide caliper, micro meter, weight scale, digital weight scale, thermometer, moisture meter, hygrometer, beaker, cylinder, temperature gauge, volt meter, ampere meter, oscilloscope etc.
ISO 14001:2015 and 45001:2018 Clause 9.1 Monitoring and measurement
In Environmental Management System standard and in OH&S management system standard it is also told about calibration for measurement devices Like Carbon emission level measurement tool, PH meter, The organization shall establish, implement and maintain a procedure(s) to monitor and measure, on a regular basis, the key characteristics of its operations that can have a significant environmental impact. The procedure(s) shall include the documenting of information to monitor performance, applicable operational controls and conformity with the organization’s environmental objectives and targets.
The organization shall ensure that calibrated or verified monitoring and measurement equipment is used and maintained and shall retain associated records
The organisation must ensure that monitoring and measurement equipment such as sampling pumps, noise monitors, toxic gas detection equipment, is calibrated or verified and that it is correctly used and maintained. It is told in ISO 45001:2018
Where from calibration can be done?
Calibration can be done from 17025 accredited lab. There are few accredited labs in Dhaka which are accredited by NABL. Only accredited lab can ensure that your device is OK. Only accredited lab can confirm that the reading of the device is accurate They follow international guide line to calibrate your devices. Usually once in a year calibration should be done.
What you should know before calibration?
You should check if the lab has accreditation certificate to calibrate the specific item. There may some tricks about it. So, verify first if the calibration lab has approval to calibrate the device or equipment. And if the master device is calibrated from accreditation body.
