TECHNICAL BULLETIN TB-7572 Analogue Surface Resistance Test Kit Made in America Operation and Maintenance identifies the technical requirements Features and Components to be verified, the measurement limits and the frequency at which those verifications shall occur. The Compliance Verification Plan A shall document the test methods and equipment used for process monitoring and measurements. If the test methods used by the B Organization differ from any of D the standards referenced in the C document, then there must be a E tailoring statement that is documented as part of the ESD Control Program Plan. Compliance verification records shall be established and maintained to provide evidence of conformity to the technical requirements. Figure 2.
