ASTM A627-03(2019)(Test Method)
Standard Test Methods for Tool-Resisting Steel Bars, Flats, and Shapes for Detention and Correctional Facilities

ABSTRACT
These test methods cover requirements for simulated service tests and testing equipment for determining the performance characteristics of various types and shapes of steels designated for use in detention and correctional facilities as fixed barriers to prevent egress and to control passage. These test methods are designed to identify levels of physical security for openings such as fixed and operable exterior and interior windows, bar gratings, grilles for mechanical ducts, and so forth in walls that enclose or separate secure areas. Drop-weight test, cutting test, deflection test, and hardness test shall be performed to meet the requirements prescribed.
SIGNIFICANCE AND USE
4.1 Security barriers used in detention/correctional facilities are a major concern for their administrative officials. These test methods are designed to identify levels of physical security for openings such as fixed and operable exterior and interior windows, bar gratings, grilles for mechanical ducts, and so forth in walls that enclose or separate secure areas.  
4.2 These test methods are intended to evaluate the resistance of these barriers to violent attacks using battering devices such as benches, bunks or tables, and so forth to bend or break the steel bars and to surreptitious attacks by cutting/abrading the steel bars over prolonged periods of time using handheld grit-type cutting/abrading media such as tungsten carbide rod saws. External attacks and attacks by corrosive agents and other means not typically available to inmates are not addressed in this standard.  
4.3 The primary purpose or result of these test methods is to approximate the levels of abuse to which these physical security barriers will potentially be subjected in the correctional/detention facility. The desired result of its use is to help provide a degree of assurance of protection to the public, facility personnel, and inmates.  
4.4 It is recommended that detention/correctional facility administrators provide for adequate training, supervision, regular inspection, and preventive maintenance programs to enable the barriers to function as intended throughout their expected service life.
SCOPE
1.1 These test methods cover requirements for simulated service tests and testing equipment for determining the performance characteristics of various types and shapes of steels designated for use in detention and correctional facilities as fixed barriers to prevent egress and to control passage.  
1.2 It is the intent of these test methods to help ensure that opening assemblies such as detention security windows, grilles, bar grating, and other physical barriers incorporating steel bars perform at or above minimum acceptable levels for control of passage to unauthorized or secure areas, for confinement of inmates and to delay or frustrate escape attempts. To meet the intent of these test methods, opening assembles must perform to grade requirements shown in Tables X1.1 and X1.2 in Appendix X1.  
1.3 These test methods apply primarily to the steels used as essential components of detention security windows, grilles, bar grating, and so forth, in opening assemblies enclosing or separating secure areas of detention/correctional facilities.  
1.4 The values stated in inch-pound units are to be regarded as standard. The SI values given in parentheses are for information only.  
1.5 This standard updates and combines two previous standards, ASTM Specifications A627 – 95 and A629 – 94, establishing new security grades and time durations.  
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.  
1.7 This international standard was developed in accordance with internationally recognized principles on standardizatio...

ASTM A400-23(Practice)
Standard Practice for Steel Bars, Selection Guide, Composition, and Mechanical Properties

SIGNIFICANCE AND USE
4.1 If the desired mechanical properties are as described in 5.1.1 for material identified as Classes P-1 through P-7, or in 5.1.2 for material identified as Classes Q-1 through Q-7, the strength level desired can be based on hardness or the equivalent tensile or yield strength as shown in Tables 1-4. If the desired mechanical properties are as set forth in 5.1.3 for material identified as Classes R-1 through R-6, the strength level is based on yield strength as shown in Tables 5 and 6.  
4.2 The user, after determining the mechanical property requirements of the critical section (that carrying the greatest stress) of the part, should select the composition or compositions from Tables 1-6 that fulfills these requirements and is most suitable for processing.
SCOPE
1.1 This practice covers the selection of steel bars according to section and to the mechanical properties desired in the part to be produced. This is not a specification for the procurement of steel. Applicable procurement specifications are listed in Section 6.  
1.2 Several steel compositions intended for various sections and mechanical property requirements are presented in Tables 1-6. The criteria for placing a steel composition in one of the three general class designations, Classes P, Q, and R (described in Section 5) are as follows:          
1.2.1 Classes P and Q  should be capable of developing the mechanical properties shown in Tables 1-4 by liquid quenching from a suitable austenitizing temperature, and tempering at 800 °F (427 °C) or higher. A hardness indicated by tests made at a location shown in Fig. 1, A, B, or C, is taken as evidence that a composition is capable of meeting other equivalent mechanical properties shown in the tables. Normal good shop practices are assumed, with control of austenitizing and tempering temperatures, and mild agitation of the part in the quenching bath.
FIG. 1 Locations in Typical Cross Sections of Steel Bars at Which Desired Properties Are Obtained  
1.2.2 Class R  should be capable of developing the mechanical properties shown in Tables 5 and 6 as hot rolled, by cold drawing, or by cold drawing with additional thermal treatment. The locations for obtaining tension tests are described in 7.2.  
1.3 It is not implied that the compositions listed in the tables are the only ones satisfactory for a certain class and mechanical property requirement. Steels with lower alloy contents are often satisfactory through the use of special processing techniques.  
1.4 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.  
1.5 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.

Standard Specification for Stainless Steel Bars and Shapes

ABSTRACT
This specification covers hot-finished or cold-finished bars except bars for reforging. It includes rounds, squares, and hexagons, and hot-rolled or extruded shapes, such as angles, tees, and channels in the more commonly used types of stainless steels. The bars shall be furnished in one of the following conditions: Condition A in which the bars are annealed, Condition H in which the bars are hardened and tempered at a relative temperature, Condition T in which the bars are hardened and tempered at a relatively high temperature, Condition S in which the bars are strain hardened or relatively light cold worked, and Condition B in which the bars are relatively severe cold worked. The material shall be subjected to a mechanical test to determine its tensile strength, yield strength, elongation, and Brinell hardness.
SCOPE
1.1 This specification covers hot-finished or cold-finished bars except bars for reforging (Note 1). It includes rounds, squares, and hexagons, and hot-rolled or extruded shapes, such as angles, tees, and channels in the more commonly used types of stainless steels. The free-machining types (Note 2) for general corrosion resistance and high-temperature service are covered in a separate specification.  
Note 1: For bars for reforging, see Specification A314.
Note 2: For free-machining stainless bars designed especially for optimum machinability, see Specification A582/A582M.

Standard Specification for Precipitation Hardening Iron Base Superalloy Bars, Forgings, and Forging Stock for High-Temperature Service

ABSTRACT
This specification covers hot-finished or cold-finished precipitation hardening iron base superalloy bars, forgings, and forging stock for high-temperature service. The mechanical properties of these alloys are developed by suitable solution treating and precipitation hardening treatments. Two grades of iron base alloy are covered; Grade 660 and Grade 662 (bars and forgings). The material shall meet the requirements as to stress rupture properties specified. The material shall conform to the chemical, mechanical, and metallurgical properties requirements specified.
SCOPE
1.1 This specification2 covers hot-finished or cold-finished precipitation hardening iron base superalloy bars, forgings, and forging stock for high-temperature service. The mechanical properties of these alloys are developed by suitable solution treating and precipitation hardening treatments.  
1.2 Two grades of iron base alloy are covered. Selection will depend upon design, service conditions, mechanical properties, and elevated temperature characteristics.  
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. SI units are shown in brackets. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.  
1.4 Unless the order specifies an “M” designation, the material shall be furnished to inch-pound units.  
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.

ASTM B351/B351M-13(2023)(Specification)
Standard Specification for Hot-Rolled and Cold-Finished Zirconium and Zirconium Alloy Bars, Rod, and Wire for Nuclear Application

ABSTRACT
This specification covers UNS R60001, R60802, R60804, and R60901 wrought zirconium and zirconium alloy bars, rods, and wires. All material grades covered should conform to the required chemical composition requirements. Elements that are intentionally added to the melt should be identified, analyzed and reported in the chemical analysis. The zirconium and zirconium alloys should be made from ingots produced by vacuum or plasma arc melting, vacuum electron-beam melting, a combination of the three methods, or other melting processes conventionally used for reactive metals. All processes should be performed in furnaces specifically for reactive metals. Mill products included in this specification should be formed with conventional extrusion, forging, or rolling equipment that is used in primary ferrous and nonferrous plants. The cold worked and annealed materials should be in fully annealed condition unless otherwise specified. Hot worked shapes should be furnished in not descaled, mechanically descaled, or mechanically descaled and pickled finish, while cold-worked shapes should be furnished in cold-worked, ground, or pickled finish.
SCOPE
1.1 This specification covers four grades of wrought zirconium and zirconium alloy bars, rod, and wire as follows:  
1.1.1 R60001—Unalloyed grade,  
1.1.2 R60802—Zirconium-Tin alloy (Zircaloy 2),  
1.1.3 R60804—Zirconium-Tin alloy (Zircaloy 4), and  
1.1.4 R60901—Zirconium-Niobium alloy.  
1.2 Unless a single unit is used, for example corrosion mass gain in mg/dm2, the values stated in either inch-pound or SI units are to be regarded separately as standard. The values stated in each system are not exact equivalents; therefore each system must be used independently of the other. SI values cannot be mixed with inch-pound values.  
1.3 The following precautionary caveat pertains only to the test method portions of this specification. 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.  
1.4 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.
