38、rom representative protective clothing as definedby this standard.6.2 Performance Testing:6.2.1 Performance RequirementThe CS50 of test speci-mens shall not be less than 14 m/s (2750 f/m) or the cut throughtime shall not be less than 1.5 s at both 45 and 90.7. Certification7.1 General:7.1.1 Protecti

39、ve garments or protective devices that arelabeled as complying with this standard shall meet or exceedall applicable requirements specified in the standard and shallbe certified.7.1.2 All certifications shall be performed by an approvedcertification organization.7.1.3 Compliance protective garments

40、or protective devicesshall be labeled and listed. Such protective garments orprotective devices shall also have a label and identification thatmeets the requirements specified in Section 9.7.2 Certification Program:7.2.1 The certification organization shall not be owned orcontrolled by manufacturers

41、 or vendors of the product beingcertified. The certification organization shall be primarilyengaged in certification work and shall not have a monetaryinterest in the products ultimate profitability.7.2.1.1 The certification organization should have sufficientbreadth of interest and activity so that

42、 the loss or award of aspecific business contract would not be a determining factor inthe financial well-being of the organization.7.2.2 The certification organization shall refuse to certifyproducts to this specification that do not comply with allapplicable requirements of this specification.7.2.3

43、 The contractual provisions between the certificationorganization and the manufacturer shall specify that certifica-tion is contingent upon compliance with all applicable require-ments of this specification. There shall be no conditional,temporary, or partial certifications. Manufacturers shall not

45、at if requirements change, the product should be brought intocompliance with the new requirements by a stated effectivedate through a compliance review program involving allcurrently listed products. Without these clauses, certifierswould not be able to move quickly to protect their names,marks, or

46、reputations. A product safety certification programFIG. 1 Protective Pants / TrousersFIG. 2 Chaps, Aprons, or LeggingsF1897083would be deficient without these contractual provisions and theadministrative means to back them up.7.2.4 A certification organization shall have, or contractwith, laboratory
