Quality Infrastructure
• To meet with concerns we
need:
 Criteria, reference that we
call it our standards
 Complying tools with the
reference (conformity
assessment or evaluation of
conformity)
 Assuring the traceability and
accuracy of the test (
metrology)
 Assuring credibility through
(accreditation)
• These forms Quality

Evaluation of Conformity
• ISO/ IEC 17000 defines conformity assessment as
demonstration that specified requirements
relating to a product, process, system, person, or
body are fulfilled.
• Definition consists of the following terms:
Demonstration methods: that include testing,
inspection, suppliers’ deceleration and certification.
Specified requirement: that relates to a standard or
agreed specifications.
Product, process, system, person or body that form
object of conformity.

Benefits of Conformity Assessment
•
•
•
•
•
Conformity assessment provides benefits to everyone in the supply and demand
chain.
For consumer :
 it is a mechanism providing confidence to consumers that the products and
services they purchase are fit for the purpose
For manufacturers and suppliers:
 it allows them to have peace of mind that they have implemented systems
within their own organizations to ensure that the products and services they
deliver meet the necessary criteria. And competitiveness.
For regulators:
 it allows them to use the conformity assessment infrastructure as part of the
process they use to ensure health and safety as well as environmental
conditions are being continuously met.
conformity assessment provide confidence facilitates the free flow of goods and
services between national boundaries.

Determination
• involve activities undertaken to assess
compliance with requirements:
Testing to determine specified characteristic
Inspection of physical characteristic
Auditing of systems and records
Evaluation of qualities
Examination of specification
Ahmad Jallad- Accerditation is technical

Calibration
• “Operation that, under
specified conditions, in a first
step, establishes a relation
between the quantity values
with measurement
uncertainties provided by
measurement standards and
corresponding indications with
associated measurement
uncertainties and, in a second
step uses this information to
establish a relation for
obtaining a measurement
result from an indication”
International Vocabulary of
metrology (VIM)

Inspection
• Some inspection activities
are closely aligned with
testing activities, others
with certification.
• “ examination of a product
design, product, process or
installation and
determination of its
conformity with specific
requirements or, on the
basis of professional
judgment, with general
requirements” ISO/ IEC
17000
