Significance and Use4.1 This practice provides basic criteria for the deve
18、lopmentand operation of a certification organization, selection ofexamination material for a written examination, and the scopeand details of a performance test. The qualifications of theexaminer and limitations on the relationship between theexaminer and the examinee are given in this practice.4.2
19、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 unintended that each individual becertified for every test that the employing agency performs.Rather it should be
20、 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 not a certified technicianshould perform a given test.4.4 Although this practice calls for certification
21、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 Structure:5.1.1 The certification organization shall be administrativelyindependent in matters pertaining to
22、 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 any other body andthat all financial matters related to the operation of thecertifying organization are se
23、gregated 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 body is administratively independent in certificationmatters from the organization of which it is part.5.1.2

In particular, commonsources of error of the test should be the basis for
42、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 questions shall cover the test method elementssuch as apparatus, specimen preparation, test procedure,
43、 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 recognized asnecessary for a testing facility in which written examinationsare administered.10.
