5.1 This guide is intended to illustrate the fabrication of ultrasonic reference blocks that are representative of the production material to be examined. Care in material selection and fabrication can result in the manufacture of reference blocks that are ultrasonically similar to the production material thus eliminating the reference block as an examination variable.1.1 This guide covers general procedures for the material selection and fabrication of reference blocks made of metal or metal alloys and intended to be used for the examination of the same or similar production materials by pulsed longitudinal ultrasonic waves applied perpendicular to the beam entry surface. Primary emphasis is on solid materials but some of the techniques described may be used for midwall examination of pipes and tubes of heavy wall thickness. Near-surface resolution in any material depends upon the characteristics of the instrument and search unit employed.1.2 This guide covers the fabrication of reference blocks for use with either the immersion or the contact method of ultrasonic examination.1.3 Reference blocks fabricated in accordance with this guide can be used to determine proper ultrasonic system operation. Area-amplitude and distance-amplitude curves can also be determined with these reference blocks.1.4 This guide does not specify reference reflector sizes or product rejection limits. It does describe typical industry fabrication practices and commonly applied tolerances where they lend clarity to the guide. In all cases of conflict between this guide and customer specifications, the customer specification shall prevail.1.5 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.1.6 This standard does not purport to address the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.

4.1 This guide is intended to provide guidance for the specification and selection of fabrication methods for silicones used in medical devices. It also provides guidance relative to testing that might be done to qualify lots of acceptable material, based on desired performance properties.4.2 Silicone manufacturers supplying material to the medical device industry should readily provide information regarding non-proprietary product formulation to their customers either directly or through the US FDA Master File program.1.1 This guide is intended to educate potential users of silicone elastomers, gels and foams relative to their fabrication and processing. It does not provide information relative to silicone powders, fluids, pressure sensitive adhesives, or other types of silicone products.1.2 The information provided is offered to guide users in the selection of appropriate processing conditions for specific medical device applications.1.3 Formulation and selection of appropriate starting materials is covered in the companion document, F2038. This monograph addresses only the curing, post-curing, and processing of elastomers, gels and foams as well as how the resulting product is evaluated.1.4 Silicone biocompatibility issues can be addressed at several levels, but ultimately the device manufacturer must assess biological suitability relative to intended use. Biocompatibility testing may be done on cured elastomers prior to final fabrication, but the most relevant data are those obtained on the finished device. Data on selected lots of material are only representative when compounding and fabrication are performed under accepted quality systems such as ISO 9001 and current Good Manufacturing Practice Regulations (21 CFR, Parts 210, 211, and 820). Extractables analyses may also be of interest for investigation of biocompatibility, and the procedures for obtaining such data depend on the goal of the study (see ISO 10993–12 and the HIMA Memorandum 7/14/93 for examples of extraction methods).1.5 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard.1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

5.1 Reference blocks fabricated in accordance with this practice will exhibit specific area-amplitude and distance-amplitude relationships only with an immersion test at 5 MHz using the search unit, test instrument and test parameters described in this practice. Comparison test at other frequencies or with uncalibrated instruments will not necessarily give the same relationships shown in this practice. See Reference (1) for area-amplitude limitations at other frequencies and transducer diameters. Also see Reference (2) for cautions regarding use of standard blocks for test standardizations.1.1 This practice covers a procedure for fabrication and control of metal alloy reference blocks used in ultrasonic examination that have a flat-surface sound entry, are cylindrical in shape, and contain flat-bottom holes (FBH) which may be used for checking the performance of ultrasonic examination instrumentation and search units and for standardization and control of ultrasonic examination of metal alloy products. The reference blocks described are suitable for use with either the direct-contact method or immersion pulse-echo ultrasonic methods.Note 1—Use of flat-surface reference blocks may not be suitable for cylindrical materials (3)2.1.2 While this procedure is basically designed for the fabrication and control of carbon and alloy steel blocks to be used in conjunction with the examination of these materials, the fabrication and control procedures may also be suitable for the preparation of blocks for other types of materials such as nickel-base alloys, certain types of aluminum alloys, and so forth. Additional procedures and controls may be required when fabricating reference blocks from other than carbon or alloy steel material. This practice shall in no way preclude the specification or addition of any supplemented requirements as deemed necessary for the specific application. This practice, however, must not be confused with, nor does it supersede Practice E127, specifically governing the fabrication and evaluation of 7075-T6 aluminum alloy ultrasonic standard reference blocks.Note 2—Practice E127 and Guide E1158 also describe procedures for selecting material, fabricating blocks, and checking response. Unlike this practice, Practice E127 has requirements for evaluation relative to a specified standard target.1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.1.4 This standard does not purport to address all of the safety problems, if any, associated with its use.

1.1 This practice establishes procedures for a quality assurance plan for structural steel fabrication for highway structures. These procedures pertain to the inspections, measurements, and tests necessary for the fabricator and owner to substantiate material and product conformance to contract requirements. The fabricator's quality control plan (QCP) is to be designed and implemented with the objective of ensuring that all materials incorporated into the work conform to contract requirements. The owners acceptance testing plan (ATP) is designed to provide assurance that the fabricator has successfully met this objective.1.2 Inherent in this practice is the assumption that design details and specifications allow maximum flexibility in procedures and processes to allow the most cost-effective fabrication to be performed consistent with the quality level specified.1.3 Alternative sampling methods, processes, procedures, and inspection equipment may be used by the fabricator when such procedures and equipment provide, as a minimum, the quality assurance required by the contract documents. Prior to applying such alternative procedures, the fabricator is to describe the procedure in a written proposal, and demonstrate to the satisfaction of the owner that the effectiveness of these alternative procedures are equal to or better than the contract requirements. In case of dispute, the procedures stipulated in the contract documents will apply.
