What is the primary objective of **FDA 21 CFR Part 11**?

**The primary objective of FDA 21 CFR Part 11 is to establish criteria under which the Agency considers electronic records and electronic signatures trustworthy, reliable, and equivalent to paper records and handwritten signatures executed on paper.** This equivalency, per §11.1(a), enables electronic technology use while ensuring authenticity, integrity, and non-repudiation through controls like validation (§11.10(a)), audit trails (§11.10(e)), and signature linking (§11.70).

Who is legally or professionally required to comply with **FDA 21 CFR Part 11**?

**FDA 21 CFR Part 11 applies to organizations using electronic records created, modified, maintained, archived, retrieved, or transmitted under FDA predicate rules, or submitted electronically to the Agency.** Per §11.1(b), it targets life sciences firms relying on electronic records in lieu of paper for regulated activities (e.g., batch records under 21 CFR 211), including closed (§11.10) or open systems (§11.30), but excludes paper records transmitted electronically.

Does **FDA 21 CFR Part 11** require an external audit or third-party certification?

**No, FDA 21 CFR Part 11 does not require external audits or third-party certification.** Compliance is demonstrated through internal controls, validation, SOPs, and inspection readiness (§11.1(e)), with systems and documentation readily available for FDA review. The 2003 guidance emphasizes risk-based approaches without mandating external validation.

How often should an assessment for **FDA 21 CFR Part 11** be performed?

**FDA 21 CFR Part 11 does not prescribe a fixed frequency for assessments; they must occur via change control, periodic reviews, and risk-based validation lifecycles.** Controls like documentation change procedures (§11.10(k)) and operational checks (§11.10(f)) require ongoing evaluation, with reassessments triggered by system changes or predicate rule updates per 2003 guidance.

What are the consequences of non-compliance with **FDA 21 CFR Part 11**?

**Non-compliance with FDA 21 CFR Part 11 can result in FDA enforcement actions including Form 483 observations, warning letters, product holds, and predicate rule violations.** The 2003 guidance notes continued enforcement of access controls (§11.10(d)), signatures (§§11.50-11.300), and data integrity, potentially leading to recalls or injunctions if records lack trustworthiness.

Can **FDA 21 CFR Part 11** be mapped to other international frameworks?

**Yes, FDA 21 CFR Part 11 controls such as audit trails, access limitation, and electronic signatures can align with frameworks like EU Annex 11 through shared principles of data integrity and validation.** However, Part 11's narrow scope and enforcement discretion (§11.10) require case-specific mapping without formal harmonization.

What is the first step to begin implementing **FDA 21 CFR Part 11**?

**The first step to implement FDA 21 CFR Part 11 is to establish a formal applicability framework mapping predicate rules to electronic records and assessing business reliance.** Per 2003 guidance, document whether records are maintained electronically in lieu of paper or relied upon for regulated activities, classifying systems as closed (§11.3(b)(4)) or open (§11.3(b)(9)).

What is the primary objective of **ISO 17025**?

**ISO/IEC 17025:2017 specifies general requirements for the competence, impartiality, and consistent operation of testing and calibration laboratories.** It ensures technical validity of results through metrological traceability, measurement uncertainty evaluation, validated methods, and controlled processes under Clauses 6 (resources) and 7 (processes), enabling global acceptance via ILAC mutual recognition.

Who is legally or professionally required to comply with **ISO 17025**?

**No legal mandate exists for ISO/IEC 17025:2017 compliance, but it is professionally required for testing, calibration, and sampling laboratories seeking accreditation.** Suppliers, regulators, and customers in regulated sectors (e.g., manufacturing, environmental, forensics) refuse non-accredited results, as accreditation attests to competence within a defined scope by ILAC-signatory bodies like ANAB or A2LA.

Does **ISO 17025** require an external audit or third-party certification?

**ISO/IEC 17025:2017 requires accreditation via external assessment by an authorized accreditation body, not certification.** Assessments include document review, on-site evaluation with witnessed testing/calibration, and scope-specific competence verification; laboratories are "accredited," distinguishing it from ISO 9001-style certification.

How often should an assessment for **ISO 17025** be performed?

**ISO/IEC 17025:2017-accredited laboratories undergo initial accreditation followed by regular surveillance and reassessment by the accreditation body.** Surveillance visits occur typically annually, with full reassessments every 2 years, plus ongoing proficiency testing, internal audits (at planned intervals), and management reviews to ensure continual compliance.

What are the consequences of non-compliance with **ISO 17025**?

**Non-compliance with ISO/IEC 17025:2017 results in accreditation suspension, scope reduction, or withdrawal by the accreditation body.** This leads to rejected test/calibration results by customers/regulators, lost contracts, market exclusion, and potential legal/reputational risks from invalid data in safety-critical applications.

Can **ISO 17025** be mapped to other international frameworks?

**Yes, ISO/IEC 17025:2017 management system requirements (Clause 8) map directly via Option B to ISO 9001.** This allows integration of shared elements like internal audits, management review, and corrective actions, while retaining unique technical requirements for competence, traceability, and impartiality.

What is the first step to begin implementing **ISO 17025**?

**The first step for ISO/IEC 17025:2017 implementation is a clause-by-clause gap analysis against current practices.** This identifies deficiencies in impartiality (Clause 4), resources (Clause 6), processes (Clause 7), and management systems (Clause 8), prioritizing high-risk areas like measurement uncertainty and metrological traceability for remediation.
