2.2 OUTDATED STANDARDS
Requests for use of outdated standards may be granted by API at its sole discretion, in individual cases where the stan- dard has been revised since testing commenced and the impact of the revision on the test results is considered small. Under no circumstances shall a facility certified to per- form testing under an outdated standard represent that it is able to perform testing under the standard without having the revised equipment or procedures in place and operational. If a certified facility does not wish to comply with a revision to this or an incorporated standard, it must notify API in writing that it is returning its certification and will no longer represent itself as a certified facility.
4.2 EQUIPMENT SUIT ABILITY
In general, the facility must have available under its control the specific test equipment required to test proto- col for which certification is requested or has been granted. Control of the equipment can be obtained through ownership, or by rental. A given piece of equipment can be used to sat- isfy the requirements of several test protocols, but it must be available for a specific test when required for testing under protocol. For example, a facility could own one couple calibration block that it uses to calibrate the thermo- couples on all its equipment, but it must be available for spot- checking or recalibration any time it is required. Modification (other than repair) of the equipment which was present time of certification must be approved by API as acceptable prior to the modification. Failure to obtain approval of modifications may result in rejection of test results at the discretion of API.
4.3 EQUIPMENT
Equipment used for testing under this standard shall not be modified after facility certification without the prior written of does not apply to common repairs, installations of devices for testing or replacement-in-kind of defective or broken its discretion, may require recalibration of instruments or systems, includ- ing retesting of individual standard devices following modifi- cation of the equipment. unapproved modification of testing equipment can result in API’s rejection or delay in certifying subsequent test results. facility shall exert no proprietary rights any modification of the test API shall be able to place any information concerning the physical facilities, methods, or procedures used in the testing into the public domain without restriction. API is interested in modifications or improvements to the test facility that improve the accuracy, time required, or cost of testing that might be included in the appropriate testing standard at some future time. Suggestions should be directed to Coordinator.
