11、nce Elements5.1 Scope of AccreditationAlaboratory may be accreditedfor less than the full range of work it undertakes(see GuideE 1224).Accordingly,surveillance procedures usually addressonly laboratory work performed within the formally definedscope of accreditation,unless other activities of the la

13、ance Procedures6.1 Information Updating:6.1.1 An accredited laboratory should provide informationto the accrediting body on matters affecting its accreditation.6.1.2 Questionnaires may be used to solicit updated infor-mation between routine assessments and usually just prior to anassessment.Signific
14、ant changes in personnel,facilities,equip-ment,or management may precipitate an assessment,morefrequent proficiency tests,or other surveillance activity by theaccrediting body.6.2 Routine Assessment:6.2.1 Regularly scheduled routine on-site assessments areone of the means of surveillance of accredit
