4.1 The purpose of these test methods is to provide reliable and repeatable nonballistic test methods and conditioning procedures for the evaluation of head protection used in law enforcement and corrections applications.  
4.2 It is anticipated that these test methods will be referenced by certifiers, purchasers, or other users in order to meet their specific needs. Those users will specify which test methods and conditioning procedures are applicable, and will specify any performance categories or levels.  
4.3 These test methods include some procedures and references to other standards to ensure that relevant properties are addressed.
SCOPE
1.1 This standard provides nonballistic test methods and conditioning procedures for assessing head protection (that is, helmet and face shield) worn by law enforcement and corrections officers.  
1.1.1 Conditioning procedures are included to assess durability in terms of resistance to chemicals and cleaning products, extreme temperatures, weathering, and absorption of liquids.  
1.1.2 Test methods are included to assess the protective performance against hazards including impact/bump, projectiles (other than bullets), flame, and liquids.  
1.1.3 Test methods are included to assess safety and ergonomic aspects of retention system strength, stability of the helmet on the wearer’s head, corrosion resistance, and face shield visual acuity, field of view, scratch resistance, and anti-mist properties.
Note 1: These test methods reference published standards from ASTM International and other standards developing organizations. Appendix X1 contains a summary of test methods included in this standard, along with the source and purpose for each.  
1.2 These test methods do not address eye protection other than face shields that are attached to the helmet.  
1.3 It is anticipated that these test methods will be referenced by suppliers, certifiers, purchasers, or other users to meet their specific needs. Those users will specify, in other standards and specifications, which test methods and conditioning procedures are applicable and will specify any performance categories or levels.  
1.3.1 If there is a discrepancy between these test methods and a user-supplied document, the user-supplied document shall take precedence.  
1.4 In these test methods, “other standards and specifications” and “unless specified elsewhere” refer to documents (for example, military standards, purchase specifications) that require the use of these test methods. Purchasers and other users are responsible for the “other standards and specifications” and for specifying any requirements that supersede those of these test methods.  
1.5 Units—The values stated in either SI units or inch-pound units are to be regarded separately as standard. 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.  
1.6 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.

Standard Test Methods for Ballistic Resistant Head Protection

SIGNIFICANCE AND USE
5.1 U.S. Department of Defense and U.S. Department of Justice standards and specifications may require these test methods for assessing the penetration resistance and backface deformation of ballistic-resistant helmets and face shields.  
5.2 These test methods may be used by private-sector and government laboratories, manufacturers, research and development organizations, and others assessing the ballistic resistance of helmets and face shields or performing research and development of new materials.  
5.3 It is intended that these test methods will be referenced by other standards and specifications.
SCOPE
1.1 These test methods describe the tests for ballistic-resistant head protection which consists of helmets and face shields. Test methods address backface deformation, resistance to penetration, and ballistic limit. It is anticipated that these test methods will be referenced by purchasers or other users in specifications or performance standards for helmets in order to meet the user’s specific needs.
Note 1: ISO/IEC 17025 specifies the general requirements for the competence to carry out tests or calibrations, or both. It covers testing and calibration performed using standard methods, non-standard methods, and laboratory-developed methods.  
1.2 These test methods do not address eye protection other than ballistic-resistant face shields that are attached to the helmet.  
1.3 These test methods do not specify performance criteria or usages of the test results.  
1.4 These test methods include procedures for conditioning of test items prior to ballistic testing.  
1.5 In these test methods, “other standards and specifications” and “unless specified elsewhere” refer to documents (for example, military standards, purchase specifications) that require the use of these test methods. Purchasers and other users are responsible for the “other standards and specifications,” and for specifying any requirements that supersede those of these test methods.  
1.5.1 Other standards and specifications will specify and describe the ballistic test threats to be used.  
1.6 Units—Values stated in either the International System of Units (metric) or U.S. Customary units (inch-pound) are to be regarded separately as standard. The values stated in each system may not be exact equivalents. Both units are referenced to facilitate acquisition of materials internationally and minimize fabrication costs. Tests conducted using either system maintain repeatability and reproducibility of the test method and results are comparable.  
1.7 If there is a discrepancy between these test methods and a user supplied document, the user supplied document takes precedence.  
1.8 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.  
1.9 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 Arc Rated Eye or Face Protective Products

SIGNIFICANCE AND USE
9.1 This specification’s test method is used to determine an arc rating for eye or face protective products, including face shields, safety spectacles, goggles, or other applicable portions of the complete product that are required to meet the current version of ANSI/ISEA Z87.1. This excludes the textile or parts of the hood assemblies or other rated products that are not testable by ANSI/ISEA Z87.1. This standard does not measure optical and impact properties (see ANSI/ISEA Z87.1) but does specify requirements for optical and impact properties in accordance with that standard.  
9.2 The test method is used to measure and describe the properties of materials, products, or assemblies in response to convective and radiant energy generated by an electric arc under controlled laboratory conditions and does not purport to predict damage from light other than the thermal aspects measured.  
9.3 The specification’s test method is intended for the determination of the arc rating of a product/design, intended for use as eye or face protection for workers exposed to electric arcs. For whole body protection, additional personal protective equipment (PPE) will be required for parts not covered by this standard.  
9.3.1 Because of the variability of the arc exposure, different heat transmission values may be observed at individual sensors. The results of each sensor are evaluated in accordance with Section 16.  
9.4 This test method maintains the specimen in a static, vertical position and does not involve movement except that resulting from the exposure.  
9.5 Different exposure conditions produce different incident energies and different heat fluxes. This standard exposure is used for comparison of products and hazard assessment methods may use multiplication factors or other means for determining protection.  
9.6 The purchaser has the option to perform or have performed any of these tests to verify the performance of the eye or face protective product. Claims for failu...
SCOPE
1.1 This product specification is used to determine the arc rating and specify the requirements for products intended for use as eye or face protection for workers exposed to electric arcs. The arc rating is determined in the test with an arc which has a heat flux value of 2100 kW/m2 [50 cal/cm2/s]. Products are tested as sold.  
1.2 The products covered by this standard are in the form of faceshields attached to the head by protective helmets (hard hats), headgear, hood assemblies, safety spectacles or goggles. Faceshields, safety spectacles or goggles are tested with or without other face and head protective products, for example, sock hoods, balaclavas, sweat shirt hoods or jacket hoods.  
1.2.1 Fabric layers used in the design of face protection products such as in hood, neck guards, balaclava, meet the requirements of Specification F1506. When fabrics are designed into the protection provided for eye or face protective products, the arc rating of fabric system is first determined by Test Method F1959/F1959M.  
1.2.2 The arc rating of the eye or face protective product which requires fabric to provide protection to the face or head will not be higher than the lower arc rating of either the fabric system or the shield/visor assembly.  
1.3 The values stated in SI units shall be regarded as standard except as noted. Within the text, alternate units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, alternate systems must be used independently of the other. Combining values from the systems described in the text may result in nonconformance with the method.  
1.4 This standard does not purport to describe or appraise the effect of the electric arc fragmentation or propulsion of parts of equipment or molten metal splatter, deposited from the pressure wave containing molten metals and possible fragments of other materials except to the extent that heat energy transmissio...

5.3 This test method has been designed to provide a determination of the image formation quality of plano-protective eyewear.  
5.4 This test method offers a comprehensive refractive power measurement scanning protocol that measures the refractive power over a total 50 mm2 area in front of each eye. This measurement protocol known as the Multiple Gaze Direction Detailed Scan (MGDDS) measures the refractive powers of the zones of the plano-protective eyewear that are typically used as the wearer performs micro eye movements.
SCOPE
1.1 This test method is used to quantify the amount of refractive power (spherical and cylindrical powers) found in planoprotective eyewear.  
1.2 This test method is used to quantify the optical performance of plano-protective eyewear as identified by the weighted root mean square average wavefront error.  
1.3 This test method may also be used to measure the refractive powers of other plano-protective eyewear or ocular devices, or both.  
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 E3368/E3368M-23a(Specification)
Standard Specification for Ballistic-Resistant Helmets Worn by U.S. Public Safety Officers

SCOPE
1.1 This specification specifies minimum performance requirements and test methods for the ballistic resistance of helmets used by U.S. public safety officers and intended to protect the head against handgun and rifle ammunition.  
1.1.1 The test methods within this specification were developed and validated for broadly available helmet designs. Some helmet designs may require additional or different testing than that specified in this specification.  
1.2 This specification addresses ballistic performance in terms of:  
1.2.1 Helmet resistance to penetration (RTP) of shell, fasteners, and weak points;  
1.2.2 Helmet shell ballistic limit (V50); and  
1.2.3 Face shield RTP and deformation.  
1.3 Helmets covered by this specification are classified into RTP ballistic protection levels (see Section 8).  
1.4 This specification addresses non-ballistic performance in terms of:  
1.4.1 Helmet impact attenuation;  
1.4.2 Helmet shell compression resistance;  
1.4.3 Face shield resistance to blunt impact, deflection, and projectile impact;  
1.4.4 Face shield optics; and  
1.4.5 Retention system strength.  
1.5 Backface deformation (BFD) measurement is not addressed as a requirement for compliance with this specification. If the user of this specification is interested in BFD measurement, see Appendix X1.  
1.6 Armor appliques are not addressed within this version of the specification.  
1.7 This specification is applicable for compliance testing, verification testing, certification testing, or research and development testing.
