The powder coating shall be heat treated and cured before visible oxidation occurs. Coating materials shall undergo thickness measurements and bend testing, and shall conform to the requirements for film thickness, flexibility and continuity, impact resistance, chemical composition, and corrosion resistance. The coated H-piles or sheet piling shall be stored off of the ground on supports. While handling equipment, bundling bands for packaging and tie-down bands for shipping shall have padded contact areas so as to avoid damage and excessive deflection.

ASTM F2791-24(Guide)
Standard Guide for Assessment of Surface Texture of Non-Porous Biomaterials in Two Dimensions

SIGNIFICANCE AND USE
4.1 The term “surface texture” is used to describe the local deviations of a surface from an ideal shape. Surface texture usually consists of long wavelength repetitive features that occur as results of chatter, vibration, or heat treatments during the manufacture of implants. Short wavelength features superimposed on the long wavelength features of the surface, which may arise from polishing or etching of the implant, are referred to as roughness.  
4.2 This guide provides an overview of techniques that are available for measuring the surface in terms of Cartesian coordinates and the parameters used to describe surface texture. It is important to appreciate that it is not possible to measure surface texture per se, but to derive values for parameters that can be used to describe it. ISO has published a series of standards on surface texture measurements that may be consulted for more information (ISO 3274, ISO 4287, ISO 4288, ISO 5436-2, ISO 10993-19, ISO 12179, ISO 13565-1, ISO 19606, ISO 21920-1, ISO 21920-2, ISO 21920-3, ISO 25178-1, ISO 25178-2, ISO 25178-3, ISO 25178-6, ISO 25178-70, ISO 25178-71, ISO 25178-72, ISO 25178-73, ISO 25178-600, ISO 25178-601, ISO 25178-602, ISO 25178-603, ISO 25178-604, ISO 25178-605, ISO 25178-606, ISO 25178-607, ISO 25178-700, ISO 25178-701).
SCOPE
1.1 This guide describes some of the more common methods that are available for measuring the topographical features of a surface and provides an overview of the parameters that are used to quantify them. Being able to reliably derive a set of parameters that describe the texture of biomaterial surfaces is a key aspect in the manufacture of safe and effective implantable medical devices that have the potential to trigger an adverse biological reaction in situ.  
1.2 This guide is not intended to apply to porous structures with average pore dimensions in excess of approximately 50 nm (0.05 μm).  
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.4 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.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

1.1 This standard guide provides methods and considerations for detecting and quantifying test soil(s) from reusable medical device(s) that result from simulated-use testing of medical devices during validation of the cleaning procedures as described in the instructions for use (IFU) provided by the medical device manufacturer.  
1.2 The methods described are for detecting and measuring markers (analytes) that are components within the most common test soils and are relevant to the clinical use of the device. Appropriate test soils without protein, carbon, or carbohydrates (for example, bone) will require other methods.  
1.3 This is a part of a series of ASTM standard guides for validating cleaning instructions. The scope of the first guide in the series is selecting appropriate test soils (Guide F3208). The second in the series (Guide F3293) describes methods for inoculating medical devices with test soil. The third in the series (Guide F3321) describes methods for extracting soils for measuring residual soil on medical devices after the performance of cleaning process. This is the fourth guide in the series and describes the methods of detecting and quantifying residual analytes on the device.  
1.4 Units—The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.5 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.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM D4042-24(Test Method)
Standard Test Method for Sampling and Testing for Ash and Total Iron in Steel Mill Dispersions of Rolling Oils

SIGNIFICANCE AND USE
5.1 The life cycle and cleanliness of a recirculating steel mill rolling oil dispersion is affected by the amount of iron present. This iron consists mainly of iron from acid pickling residues and iron from attrition of the steel sheet or rolls during cold rolling. In sampling rolling oils for total iron it is difficult to prevent adherence of iron containing sludge to the sample container. Thus, the accuracy of a total iron determination from an aliquot sample is suspect. This practice provides a means for ensuring that all iron contained in a sample is included in the analysis.  
5.2 Although less significant, the ash content is still an essential part of the procedure for obtaining a total iron analysis. Generally, the ash will be mostly iron, and in many cases, could be used as a substitute for total iron in determining when to change the dispersion.
FIG. 1 Possible Holding Fixture and Assembly System
SCOPE
1.1 This test method describes a procedure for sampling and testing dispersions of rolling oils in water from operating steel rolling mills for determination of ash and total iron content. Its purpose is to provide a test method such that a representative sample may be taken and phenomenon such as iron separation, fat-emulsion separation, and so forth, do not contribute to analytical error in determination of ash and total iron.  
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.  
1.3 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. For specific warning statements, see Sections 7 and 8.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Specification for Ferrosilicon

ABSTRACT
This specification covers grades of ferrosilicon used for steel-making and foundry. The grades shall conform to the required chemical composition for silicon, carbon, sulfur, phosphorous, aluminum, manganese, calcium, and boron. Sizes available of ferrosilicon for various grades are specified. Ferroalloys exhibit varying degrees of friability; therefore, some attrition may be expected in transit, storage, and handling. Chemical analysis of the material shall be made.
SCOPE
1.1 This specification covers grades of ferrosilicon for steelmaking and foundry uses.  
1.2 The values stated in inch-pound units are to be regarded as the standard. The metric equivalents of inch-pound units (SI units) given in parentheses may be approximate.  
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM A686-92(2024)(Specification)
Standard Specification for Tool Steel, Carbon

ABSTRACT
This specification covers chemical, mechanical, and physical requirements for available wrought carbon tool steel products. These products, which include hot- or cold-finished bar, plate, sheet, rod, wire, or forgings, are normally fabricated into tools, dies, or fixtures. The selection of a material for a particular application will depend upon design, service conditions, and desired properties. An analysis of each heat of steel shall be made by the manufacturer to determine the percentage of the elements specified and these values shall conform to the chemical composition specified by the reference material. The hardness of the specimen after the specified heat treatment shall meet the minimum hardness value for the particular type of steel prescribed by the reference material. Rockwell C tests should be used where possible but light load tests may be necessary on thin specimens. The macrostructure of a specimen representing the entire cross-sectional area in the annealed condition shall be prepared in accordance with the reference material. It shall exhibit a structure free of excessive porosity, segregation, slag, dirt or other nonmetallic inclusions, pipes, checks, cracks, and other injurious defects.
