How to conduct internal auditor as per NABL/ISO/IEC 17025:2017

An internal audit is a formal laboratory activity that must be performed in accordance with a documented procedure and on a regular schedule. Laboratories may choose to conduct a full laboratory audit annually or biannually, or to audit parts of their system every month.

The internal audits should also ensure that the defined management system fulfils the requirements of ISO/ IEC 17025:2005 or ISO 15189:2012 or ISO/IEC 17043:2010 or ISO Guide 34:2009.

The audit should also ensure whether or not the requirements of the CAB’s quality manual and related documents are applied at all levels of work.

The non-conformities found during the internal audit should give valuable information for the improvement of the CAB’s management system and technical competence, which is to be used as a input to management reviews.

The quality manager may delegate the task of performing audits to personnel who are having sufficient technical knowledge with respect to the operations of the CAB, trained specifically in audit techniques and process. The auditors shall also understand requirements of ISO/IEC 17025:2005 or ISO 15189:2012 or ISO/IEC 17043:2010 or ISO Guide 34:2009 (whichever is applicable) and NABL accreditation requirements.

The audit program may include horizontal audit / vertical audit + (wherever feasible) so that all the sections/ departments are audited for every aspect/ clause of the management system and relevant standard.

Horizontal Audit - This examines one element in a process on more than one item. It is a detailed check of a particular aspect of the documentation and implementation of the management system.

Vertical Audit - This examines one sample looking at all of the inputs, operations and activities required to produce the output (result). It is a detailed check that all elements associated with the tests are implemented.

An audit timetable should be developed by each auditor in conjunction with their auditee to ensure the smooth and systematic progress of the audit.

The auditor will use the management system documents as reference (quality manual, system procedures, test methods, work instructions, records etc.), and compare what is actually happening with what these quality system documents state should happen.

The corrective actions procedure may need to be followed to reveal the root causes of some problems and to implement effective corrective actions.

The effectiveness of corrective actions should be checked by the quality manager as soon as possible after the agreed time limit has elapsed and clear/ close the non-conformity.

FIRE SAFETY

Image
  Fire safety is the set of practices intended to reduce the destruction caused by Fire. It includes those that are intended to prevent ignition of an uncontrolled fire, and those that are used to limit the development and effects of a fire after it starts. All of our work forces are trained to handle all fire fighting equipments and thus in case of emergency they need not depend on fire brigade to extinguish the fire to avoid destruction.   The fire is a common and serious emergency situation that security has to deal with. As a security guard, your main duty is to protect people and property but the fire can destroy both in a minute. You should manage and look over the fire hazard on your site. Mostly, the security guards are the first person to detect in the early stage of fire. In the case of fire, you have to know how to react quickly and confidently. So, you should know the available types of fire equipment and their location on your site. Not only this but also...

How to calculate combined uncertainty for NABL/ISO/IEC 17025:2017

Image
To calculate the uncertainty of your measurements, you'll need to find the best estimate of your measurement  and consider the results when you add or subtract the measurement of uncertainty. After measuring the individual uncertainty due to type A and type B, the combined uncertainty (U c ) is calculated as follows; U c  = √ (U 1 2  + U 1 2  + U 1 2 +……) Where; U 1,  U 2,  U 3  etc are uncertainties calculated with same units        Another method of combining uncertainty with different units of measure is fractional uncertainty. 1.      Identify the equation 2.      Calculate the fractional uncertainty for each contributor 3.      Calculate the combined uncertainty 4.      Convert the result to the desired unit of measure. The quantities that affects the measurand may not have a direct one to one relationship with it. Ind...
