Lesson 2 - QA and Standards Flashcards
What are QA and standards?
Often documents that specify the quality requirements for a product/service
True are false: QA and standards are usually mandatory.
False, they are often voluntary
How are QA and standards developed? What is the benefit of this?
Developed by consensus, makes them more robust and defensible.
List the two important areas that help establish appropriate standards in forensic science.
The organization of scientific area committees
Accreditation
What group is OSAC administered by?
The national institute of standards and technology (NIST)
What is the aim of OSAC?
To strengthen the use of forensic science by facilitating the development of technically sound forensic science standards and promoting their adoption.
What does OSAC produce?
Documents that define minimum requirements, best practices, standard protocols, and other guidance to help ensure that the results of forensic analysis are reliable and reproducible.
Outline the multi-level organizational structure of OSAC.
A forensic science standards board
Seven scientific area committees
22 discipline-specific subcommittees
FSSB resource task groups
What are the seven SACs in OSAC?
Digital/multimedia
Biology
Chemistry: seized drugs and toxicology
Chemistry: trace evidence
Physics/pattern interpretation
Scene examination
Medicine
What is the role of the forensic science standards board (FSSB) in OSAC?
Promulgation of standards,
address standard development issues,
coordinate scientific area committee work
What is the role of OSAC’s scientific area committees?
provide direction and oversee work performed by discipline specific subcommittees
What is the role of OSAC’s subcommittees?
do the work and draft the documents
True or false: OSAC has the authority to approve and enforce standards.
False. OSAC approves the standards but does not have the authority to make them standards.
What are standards development organizations (SDO)
organizations that are accredited to develop and approve standards.
Give examples of SDOs.
AAFS standards board
ASTM international
American dental association
International organization for standardization
National fire protection association
How many standards are on the OSAC registry?
200
What is accreditation?
Formal recognition by an independent body that an organization is operating according to defined standards through an assessment of laboratory and staff competence
Why might a lab want to become accredited?
Increases confidence in laboratory services
Helps to ensure laboratory is performing according as expected/defined by standards
Mandatory in some jurisdictions or required to obtain grants or private work
Explain how standards might be amplified.
accreditation standards set out requirements.
Standard may be applicable to many industries
Standards may be amplified with a supplemental document that is specific to the industry in question
Give an example of a supplemental document
ANAB 3125 supplements ISO/IEC 17025
What is ISO/IEC 17025
General requirements for the competence of testing and calibration laboratories
What is ANAB 3125?
Accreditation requirements for forensic testing and calibration
What are accrediting bodies?
The groups that assess laboratories/agencies against the standards
Give examples of accrediting bodies
ANAB
SCC
CALA
A2LA
UKAS
IAS
Who accredits the accrediting bodies?
ISO 17011
What is validation?
Process of taking a method and evaluating the ability to provide accurate and reproducible results.
Outline ISO 17025 s. 7.2.2
The lab shall validate non-standard methods, laboratory-developed methods and standard methods used outside their intended scope or otherwise modified. The validation shall be as extensive as is necessary to meet the needs of the given application or field of application.
Outline ANAB 3125, s. 7.2.2.1.1
Method validation shall:
a) Be conducted according to a validation plan
b) Include the associated data analysis and interpretation
c) Establish the data and acceptance criteria required to report a result, opinion, interpretation, or statement of conformity; and
d) identify limitations of the method
What is ISO/IEC 17025?
General requirements for competence testing and calibration laboratories
What areas does the ISO/IEC 17025 standard cover?
Reporting
Management
Measurement uncertainty
Proficiency
Method validation
Personnel
Lab structure
Equipment
Reagents
Non-conforming work
Control of records
etc.
