Suppliers of reference materials for TAPPI Test Methods are requested to certify their compliance with TAPPI Standard Practice T 1211 "Acceptance Procedures for Calibration Laboratories." This practice, current edition T 1211 sp-11, establishes guidelines for the listing of organizations as calibration laboratories or providers of standardized materials for TAPPI Standard Test Methods. Such organizations are involved with the maintenance of master instruments, calibration of test instruments, and the issuance of calibration materials or transfer standards.
The list of reference material suppliers appears in the full set of TAPPI Standards, on the TAPPI website, or is available upon request from the TAPPI Standards Department (standards@tappi.org). Organizations currently on the list will be notified that it is required that they recertify on a yearly basis in order to remain on the list. Organizations that file the recertification form with TAPPI by September 1, 2011, are assured of being listed in the next edition of the full set of methods on CD that will be released in March 2012. The filing date of September 1, 2011, has been established so that there will be time to review the responses prior to the publication deadline.
Organizations that provide reference materials for TAPPI Standard Test Methods but which are not currently on the Reference Materials list should also submit self-certification forms by September 1, 2011, in order to be included in the next full set listing. Such organizations should contact the TAPPI Standards Department (standards@tappi.org) to obtain the certification form.
