A Better World Through Accreditation 2019 by A2LA
History/Philosophy of Revision Strawman group formed in spring 2017 A2LA had some staff members/ assessors who were part of the CASCO
working group. May 2017 CASCO released DIS 17025, May 2017 Strawman group started working on identifying necessary
changes to ALACC Decided to focus on making changes complementing the risk-opportunity
approach of 17025:2017 Opportunity to incorporate previous FAQs

A Better World Through Accreditation 2019 by A2LA
What Was Moved Procedure for subdividing, compositing, homogenizing to ensure a
representative test portion is taken for testing moved from sampling (old 5.7, new 7.3) to handling test items (old 5.8, new 7.4)
7.5.1 Technical records now included all records required for audit trail that were dispersed throughout the document
Procedures for use of handwritten signatures moved from reporting (old 5.10, new 7.8) to control of data and information management (old 5.4.7, new 7.11)
Qualification of water for lab use moved from environmental conditions (old 5.3, new 6.3) to equipment (old 5.5, new 6.4)
A Better World Through Accreditation 2019 by A2LA
What Was Revised (AOAC 7.7.2) Pre-Accreditation: The laboratory shall have successful proficiency testing or interlaboratory comparison results to qualify each test method for which the laboratory wants to become accredited (see AOAC note).
(AOAC 7.7.2) Ongoing: The laboratory is required to demonstrate competence through the participation in proficiency testing based upon the scope they have (see AOAC note):

What Was Revised/Clarified (AOAC 7.7.2.) for a Biological scope:The laboratory is required to participate in one proficiency testing event each year for each method on the scope.
(AOAC 7.7.2.) for a Chemical Scope:The laboratory is required to participate in one proficiency testing event each year for each method on the scope unless it can provide evidence in the form of additional justification showing the similarity of process between each of these methods.

FAQSRequirement:In the ALACC Appendix A: Equipment table“ Temperature-controlled chambers used for testing.” ..monitored for temperature at least twice daily during its period of use. Includes ovens, incubators, water baths, etc.
Question:Does a heating block fall into that category? They are turned on at time of use only.
Answer:The philosophy in this section was that equipment left on all day needs to be monitored for temperature at least twice daily during its period of use. Essentially the same philosophy is meant for those pieces that are being used for a much more limited period of
time. However a single measurement might suffice for heat block (or possibly a measurement before and after usage if
the lab feels it necessary to demonstrate that the environmental condition was appropriate The number of measurements being dependent on the relative risk of the temperature not being at the desired set
point while it is in use for its function.
A Better World Through Accreditation 2019 by A2LA
FAQSRequirement :Section 8.8.1: Internal audits of laboratory information management systems shall be conducted at least once per accreditation cycle.
Question:What information is required to satisfy this requirement?
Answer:The laboratory is required to audit the acquisition, transfer and data storage process in the LIMS, along with permissions for access to the various data to ensure only authorized personnel can access the different parts of the LIMS.

FAQSRequirementSection 6.4.4. of the Guidelines states “that reagents, reagent solutions, sample solutions, and internal reference materials [including certified reference materials (CRMS) used as internal reference materials] shall not be used past their expiration date without recorded verification that they are still suitable for use. Media and CRMS cannot be used beyond their expiration date. Note: Expired CRMs can be qualified as Reference Materials (RMS).”
QuestionWhen can an expired CRM be used?
ANSWER:A CRM is an RM characterized by a metrologically valid procedure for one or more specified properties, accompanied by a reference material certificate that provides: 1) the value of the specified property, 2) its associated uncertainty, and 3) a statement of metrological traceability. When A CRM expires it loses a link to its uncertainty and traceability but still may be sufficiently homogeneous and stable with respect to one or more of its specified properties. Thus, a CRM that has passed its expiration date can still be used as a QC or as an RM if it is used in a manner that does not require the application of these two lost attributes as long as it is evaluated and re-qualified for suitability.
