33、 is a different plant of the same company.3. TECHNICAL REQUIREMENTS:3.1 Training Program:The company shall have a formal written program that defines the progression for education,experience, on-the-job training, classroom instruction, and evaluation for each individual tobecome approved. In additio

34、n, the company should have a documented system for assessingthe heat treaters ability to produce acceptable hardware; such a system would use inspectionand test data and failure data that is traceable to the individual heat-treater. Evidence ofproblems should trigger consideration of retraining, ree

35、valuation, withdrawing of approval, or notgranting reapproval.3.2 The functions in Table 1 shall be performed or monitored by approved personnel who have beenspecifically documented as approved for each function they perform. Determination of whichpersonnel are approved for which functions is solely

36、 the responsibility of the heat-treat companyor facility. Personnel may be approved for any or all of these functions.SAE ARP1962 Revision A- 6 -3.2.1 The functions in Table 1 may be performed by nonapproved personnel who can followinstructions when they are designated by and monitored by an approve

37、d person (for thefunction(s) being monitored). The approved person is responsible for the proper performanceof the function. Monitoring shall entail either frequent periodic witnessing or verificationchecking of the function, verification of the accuracy of shop paper, test results, and inspectionre

38、cords, and stamping, initialing, or signing off the shop paper, test results, and inspectionrecords by approved personnel. The frequency of witnessing shall be determined by heat-treating company approved personnel based on their confidence in the experience andcapability of the nonapproved personne

39、l. Monitoring does not imply constant visual contact.3.2.2 Personnel requiring approval are heat-treaters, including leads, supervisors, foremen,inspectors, laboratory technicians, heat-treat planners (2.2.1), engineers or metallurgists, andall other personnel performing or monitoring the functions

40、listed in Table 1 with the exceptionslisted below:1. Foremen and supervisors in captive heat-treat shops who are responsible for other activitiesand whose function in the heat-treat department is only administrative.2. Manufacturing sequence planners (2.2.2) in captive heat-treat facilities unless t

Metallurgists and other graduate engineers who are proficient or have been trained in thesefunctions and who are performing only functions li

43、sted in footnote 2 to Table 1.6. Personnel performing functions listed in footnote 3 to Table 1, who do not work in the heattreat department; however, documentation of training in the functions being performed isrequired.3.3 Approval Guidelines:The following describes the guidelines for a heat-treat

44、er to be approved and perform the specificfunctions listed in Table 1 for the specific processes and materials listed in Table 2.3.3.1 Required for approval are a minimum on-the-job training time (suggested times are shown inTable 2) with waivers for experience as defined in 3.3.1.1; completion of a

45、 minimum amount ofclassroom instruction (suggested times are shown in Table 1) with waivers for experience asdefined in 3.3.1.1; and passing of an evaluation management may use judgment to modify bydecreasing the suggested minimum training and/or classroom instruction times while providingcompetence

This shall be defined in the formal written program requirements in 3.1.SAE ARP1962 Revision A- 7 -3.3.1.1 Prior Experience: Personnel with verifiable, documented heat-treating experience in each ofthe specific material or process categories for a time equivalent to on-the-job training inTable 2 m

47、ay be approved for those categories after classroom instruction (3.3.1.3) andpassing the evaluation specified in 3.3.1.4. On-the-job training requirements herein may bewaived with equivalent experience. Classroom instruction may be waived with 5 years ofexperience. Classroom instruction may be waive

48、d for metallurgists and other graduateengineers. Experience and training in one category shall not be the basis for approval in anunrelated category. The evaluation in 3.3.1.4 is always required.3.3.1.2 On-the-Job Training: On-the-job training shall cover both the specific material and processcatego

49、ries listed in Table 2 and the specific job functions listed in Table 1 for which theindividual will be approved. In addition, such training should cover quality control, processcontrol, nondestructive inspection and testing (hardness, etc.), specifications, pyrometry,inspection, and laboratory testing as related to individuals job function.
