INTRODUCTION
General Requirements for the Competence of Testing and Calibration Laboratories, ISO/ IEC 17025:2017
clause 8.8 and 8.9 requires that a laboratory shall periodically, and in accordance with a predetermined
schedule and procedure, conduct:
a. Internal audits of its activities to verify that its operations continue to comply with the requirements of
the management system and ISO/ IEC 17025:2017, and
b. Management reviews of its management system and its activities to ensure their continuing
suitability and effectiveness, and to introduce any necessary changes or improvements.
Similar requirements are stated in ISO 15189:2012, ISO/IEC 17043:2010 and ISO 17034:2016 in various
clauses for Internal Audit and Management Review.
It is assumed that the CABs have implemented a management system that meets the requirement of
ISO/IEC 17025:2017 or ISO 15189:2012, ISO/IEC 17043:2010 and ISO 17034:2016. This document has
been prepared to give CABs guidance on how to establish a program for internal audit and management
review. The document consists of two sections: Section A – Internal Audit and Section B – Management
Review.
The guidelines given in this document are general in nature. The actual accomplishment of an internal
audit or a management review depends on the size, scope and organisation structure of the CAB and, for
the smaller CAB, many of the items described in this document can be carried out in a simplified manner.
NABL, at any time, may call for the internal audit and/ or management review reports from the CABs.

1. Objectives of Internal Audit
1.1 The CAB should conduct internal audits of its activities to verify that the operations continue
to comply with the requirements of defined management system.
1.2 The internal audits should also ensure that the defined management system fulfils the
requirements of ISO/ IEC 17025:2017 or ISO 15189:2012 or ISO/IEC 17043:2010 or ISO
17034:2016.
1.3 The audit should also ensure whether or not the requirements of the CAB’s Management
System Document / Quality Manual and related documents are applied at all levels of work.
1.4 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 an input to management review.

2. Organisation of Internal Audit
2.1 The internal audits should be carried out periodically according to predetermined schedule
and procedure to verify that the CAB operations are continually complying with the defined
requirements of the management system.
2.2 The audit should be programmed such that each element / activity of the management
system is checked at least once a year irrespective of the size of the CAB, all the activities,
all personnel, all procedures, all test methods to be covered in the internal audit. However at
the time of internal audit, the assessment of technical competence through witnessing the
test/ calibration may not be necessary.
2.3 In large CABs it may be advantageous to establish a plan whereby the different element of
management system or different sections of the CAB are audited throughout the year. If the
entire management system cannot be audited in one session, then the CAB must ensure
that all areas are audited throughout the year.
2.4 The person responsible for management system has the responsibility for planning and
organizing the audit and he / she should ensure that the audits are carried out in accordance
with the schedule plan.
2.4 The audits shall be carried out by qualified personnel who understand the technical
requirements they are auditing and who are trained specifically in auditing techniques and
processes. Wherever resources permit this audit shall be done by CAB personnel only to
establish the extent of conformity of the CAB to documented requirements or standards.
2.5 The person responsible for management system 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 17025:2017 or ISO 15189:2012 or ISO/IEC
17043:2010 or ISO 17034:2016 (whichever is applicable) and NABL accreditation
requirements.

2.6 In large CABs carrying out a wide range of technical activities, it may be necessary for
audits to be carried out by team of individuals. One of the auditors may act as a lead auditor;
however, the responsibility of the conduct of audit lies with the person responsible for
management system.
2.7 In small CABs, the person responsible for management system may carry out the audit, but
the management should ensure that the activities of the quality manager are audited by
another person.
2.8 The auditor shall be independent of the activity to be audited and personnel shall not audit
their own activities.
2.9 Where a CAB has accreditation for site activities, or for sampling, these activities must be
included in the audit program.
2.10 Audits carried out by the other parties, such as customers or NABL, cannot be considered to
substitute for or override the CAB’s own internal audit responsibilities.

3. Planning of Audit
3.1 An audit plan needs to be established by the person responsible for management system and
should include the audit scope, the audit criteria, the audit schedule, reference documents
(such as the CAB’s Management System Document / Quality Manual and audit procedure)
and audit team members.
3.2 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 activity are implemented.
3.3 Each auditor should be assigned specific management system elements or functional
departments to audit. Such assignments should be made by the person responsible for
management system or the lead auditor in consultation with the auditors concerned. The
auditors should have adequate technical knowledge of the activities they are to audit.
3.4 Working documents required to facilitate the auditor’s investigations and to document and
report results, may include:
- ISO/ IEC 17025:2017 or ISO 15189:2012 or ISO/IEC 17043:2010 or ISO 17034:2016.
- CAB’s Management System Document / Quality Manual and associated documents such
as system procedures, test methods, work instructions, records etc.
- Checklist used for evaluating management system elements (normally prepared by the
auditor assigned to audit that specific element).

- Forms for reporting audit observations, such as non-conformity form or corrective action
form. These forms should include nature of non-conformity, agreed corrective action, time
required for corrective actions and confirmation that the corrective action has been taken
and is effective.
3.5 An audit timetable should be developed by each auditor in conjunction with their auditee to
ensure the smooth and systematic progress of the audit.
3.6 Prior to the actual audit, a review of documents, manuals, previous audit reports and records
should occur to check for compliance with the system criteria and to develop a checklist of
key issues to be audited.

4. Implementation of Internal Audit
4.1 The implementation of the audit consists of investigation and analysis.
4.2 The opening meeting would introduce the audit team, confirm the audit criteria, review the
audit scope, explain the audit plan and procedure, clarify any relevant details, and confirm
the timetable including the time or date and attendees for the closing meeting.
4.3 The investigation process for gathering objective evidence will involve asking questions,
observing activities, examining facilities, and examining records. The auditor will be
examining the conformity of the activities with the quality system.
4.4 The auditor will use the management system documents as reference (management system
document / 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.
4.5 At all times during the audit, the auditor will be seeking objective evidence that the
management system requirements are being fulfilled. Evidence should be collected as
efficiently and effectively as possible and without prejudice or upset to the auditees.
4.6 Non-conformities should be noted if they seem significant, even where they are not covered
by checklists, and should be investigated further to identify the underlying problems.
4.7 All audit observations should be recorded. After all activities have been audited, the audit
team should carefully review and analyse all of their observations to determine which are to
be reported as non-conformities and which can be included as recommendations for
improvement.
4.8 The audit team should prepare a clear concise report supported by objective evidence of
non-conformities and recommendation for improvement. The non-conformities should be
identified in terms of specific requirements of CAB’s Management System Document /
Quality Manual and related documents against which the audit has been conducted.

4.9 The audit team should hold a closing meeting with the top management of the CAB and
those responsible for the functions concerned. The main purpose of this meeting is to
present audit findings and report to top management in such a manner so as to ensure that
they clearly understand the results of the audit, and take the appropriate corrective action
based on root cause analysis.
4.10 The person responsible for management system should present observations, taking into
account their perceived significance (both positive and negative aspects), and conclusions
regarding the management system’s compliance with the audit criteria. The non-conformities
identified during the audit should be noted and the appropriate corrective action and time
limit for actions should be agreed upon.

5. Follow up of Corrective Actions
5.1 The implementation of the agreed corrective action is the responsibility of the person
responsible for management system.
5.2 When a non-conformity that may jeopardize the result of calibration / testing / medical testing
/ PT / RM, is discovered the corresponding activity should be halted until appropriate
corrective action has been taken to lead to satisfactory results. In addition, results that may
have been affected by the non-conforming work should be investigated and customers
informed if the validity of corresponding certificates/ reports is in doubt.
5.3 The corrective actions procedure may need to be followed to reveal the root cause of some
problems and to implement effective corrective actions.
5.4 The effectiveness of corrective actions should be checked by the person responsible for
management system as soon as possible after the agreed time limit has elapsed and clear /
close the non-conformity.

6. Records and Reports of Internal Audit
6.1 A complete record of the audit should be maintained even if non-conformity has not been
found. These records provide the management with continuous history of performance. All
records must be clearly documented and readily accessible.
6.2 Each non-conformity identified should be recorded, its nature, possible cause(s), corrective
action required and appropriate time limit for its clearance.
6.3 The report should include the following information:
a. name(s) of the auditor(s)
b. date of audit
c. details of all areas audited and audit plan
d. the positive or good aspects of the operations
e. any non-conformity identified along with their document references
f. any recommendations for improvement
g. corrective actions agreed, time period allowed for completion, and person responsible
for carrying out actions.
h. corrective actions taken and date of confirmation of completion of corrective action.
i. signature of person responsible for management system / quality manager confirming
closure of the non-conformities and corrective action taken.
6.4 The person responsible for management system should ensure that the report of the audit
and, where appropriate, individual non-conformities, are seen by the CAB’s top management.
The trends in results of internal audit and the corrective actions should be analysed by the
person responsible for management system and a report prepared for review by the top
management at the management review meeting.
6.5 Audit records may be retained for a minimum period of three years.

7. Additional Unscheduled Audits
7.1 It may be necessary for CABs to carry out additional unscheduled audits whenever there is
reason to doubt the effectiveness of the management system. For example, when a non-
conforming work has been detected or the CAB has received a complaint which raises a
doubt on its competence and therefore results etc.
7.2 The additional audit may confine to only that area where the non-conformity has been
detected or the complaint has been received.
7.3 The procedure followed is similar to that of the full audit.

1. Objectives of Management Reviews
1.1 The top management of the CAB shall periodically conduct a review of the CAB’s
management system and technical activities to ensure their suitability and effectiveness and
to introduce any necessary changes or improvements.
1.2 Management reviews should be planned to establish what changes, if any, are necessary to
ensure that the management system for the CAB continue to meet both the CAB ’s needs
and the requirements of ISO/ IEC 17025:2017 or ISO 15189:2012 or ISO/IEC 17043:2010 or
ISO 17034:2016 whichever is applicable. Quality policy and objectives should be reviewed
and revised if necessary.
1.3 Management review should also take note of changes that have taken place (or are expected
to take place) in the organisation, facilities, equipment, procedures and / or activities of the
CAB and ensure (through person responsible for management system) that management
system continues to conform to the requirements of relevant standard.
1.4 The need for changes to the system may also arise as a result of findings from internal or
external quality audits, inter-laboratory comparisons or proficiency tests, surveillance or
reassessment visits by NABL / regulatory bodies, complaints from customers or change in
policies of NABL or APAC/ ILAC.

2. Organisation of Management Review
2.1 The top management of the CAB should be responsible for conducting reviews of the
management system.
2.2 Those members of top management have overall responsibility for the design and
implementation of the CAB’s management system, and for taking decisions resulting from the
findings of internal audits, should be involved in management reviews. As a normal practice
management review shall be organized after the internal audit.
2.3 The person responsible for management system should be responsible for ensuring that all
reviews are conducted in a systematic manner according to an established procedure, and
that the management reviews are recorded.
2.4 The person responsible for management system should also be ensure that any action
identified during a review is implemented within the agreed time limit.
