The qualifications of theexamine
18、r and limitations on the relationship between theexaminer and the examinee are given in this practice.4.2 The basic criteria provided by this practice is intended tobe supplemented by more specific criteria serving the require-ments of the certification organization.4.3 It is unrealistic and uninten
19、ded that each individual becertified for every test that the employing agency performs.Rather it should be a goal of an agency that a majority ofpersonnel normally performing a given test are certified.Depending on the purpose of the testing, it may be appropriatefor the client to specify whether or
20、 not a certified technicianshould perform a given test.4.4 Although this practice calls for certification specific to asingle ASTM test method, it is not intended that the certifica-tion organization avoid grouping related test methods in theinterest of efficiency.5. Certification Organization5.1 St
21、ructure:5.1.1 The certification organization shall be administrativelyindependent in matters pertaining to certification. Administra-tively independent means that all policy decisions relating tocertification matters are the sole decision of the certifyingorganization and not subject to approval by
22、any other body andthat all financial matters related to the operation of thecertifying organization are segregated from those of the parentor affiliated organization.5.1.1.1 A certifying organization that is not a legal entity inand of itself shall provide proof that the organizations gov-erning bod
23、y is administratively independent in certificationmatters from the organization of which it is part.5.1.2 The certification organization shall disclose, throughpublication of a publicly available document, rules and proce-dures that describe how the certificant, the employer, and thespecifying entit
24、y have input into the policies and decisions ofthe organization.5.2 Resources:5.2.1 The certification organization shall disclose, throughpublication of a publicly available document, evidence that theorganization has the financial resources to properly conduct thecertification activities.5.2.2 The

41、, as well as details. In particular, commonsources of error of the test should be the basis for a number ofexamination questions. A basic understanding of the principlesunderlying the test method and the basis of some of therequired calculations for the test method should also bestressed. The questi
42、ons shall cover the test method elementssuch as apparatus, specimen preparation, test procedure, andreport requirements.9.3 The written examination shall be given in a room thatprovides the lighting level, noise control, work space, ventila-tion, and temperature control that is universally recognize
43、d asnecessary for a testing facility in which written examinationsare administered.10.
