General Information

Abstract

ABSTRACT
This specification covers eye protectors, exclusive of helmet-mounted visors, designed for use by riders of motorcycles, mopeds, and snowmobiles for off road use that minimize or significantly reduce injury to the eye and adnexa as a result of impact and penetration by objects that may be kicked up from the road, track, trail, or snow surfaces and made airborne and, as such, likely to cause eye discomfort or injury. This specification does not address shield-type eye protectors such as are connected to, integral to, and/or supported by protective helmets. Protective eyewear offers protection only to the eyes and does not protect other parts of the head, face, or neck. Protectors are divided into two types, goggles or spectacles, depending on their design characteristics. This specification does not apply to prescription eyewear. It covers material classification, general requirements (materials of construction, cleanability, Construction, and finish and coatings), performance requirements, specimen preparation, test methods (optical tests, mechanical tests), cleaning, and product marking.

1.2 Protectors are divided into two types, goggles or spectacles, depending on their design characteristics.  
1.3 This specification does not apply to prescription eyewear. (Warning—Impact-resistant prescription spectacles that conform to the standard specifications of ANSI Z87.1 should be used if spectacles are to be worn under goggle-type eyewear as covered by this specification.)  
1.4 In this specification, the use of the word “shall” indicates a mandatory requirement. The word “should” indicates a recommendation.  
1.5 Units—The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. Metric units of measure in this specification are in accordance with the International System of Units (SI). If a value for measurement as given in this specification is followed by an equivalent value in other units, the first stated is to be regarded as the requirement. A given equivalent value may be approximate.  
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.

ASTM F2812-12(2018) - Standard Specification for Goggle- and Spectacle-Type Eye Protectors for Selected Motor Sports

English language (6 pages)

Overview

ASTM F2812-12(2018) is the standard specification for goggle- and spectacle-type eye protectors used in selected motor sports. Developed by ASTM International, this standard addresses the requirements for non-helmet-mounted eye protection for riders of motorcycles, mopeds, and snowmobiles, specifically for off-road environments. The primary purpose is to minimize or significantly reduce injury to the eyes caused by the impact or penetration of objects made airborne from the surface during riding.

This specification classifies protectors as either goggles or spectacles, based on their design, and outlines standards for materials, construction, performance, cleanability, testing methods, and product marking. It is important to note that prescription eyewear and helmet shield-type protectors are outside this standard's scope.

Key Topics

  • Product Types Covered:
    • Goggle-type eye protectors (forms a seal with the face)
    • Spectacle-type eye protectors (does not form a tight seal with the face)
  • Performance Requirements:
    • Impact resistance (tested under various temperatures and velocities)
    • Mechanical durability against separation, dislodgment, and delamination
    • Optical criteria including haze, prismatic imbalance, and refractive power
    • Ultraviolet (UV) transmittance compliance and stability
    • Flammability resistance to ensure safety in diverse environments
  • Materials and Construction:
    • Non-irritating materials for facial contact
    • Resistance to changes in hardness, flexibility, or strength due to perspiration and oils
    • Headbands must be secure and adjustable
  • Testing and Quality Assurance:
    • Comprehensive procedures for optical and mechanical testing
    • Requirements for cleaning, surface finish, and labeling
  • Marking and Information:
    • Permanent markings for manufacturer and model identification
    • Instructions and warnings regarding use, cleaning, and replacement

Applications

The ASTM F2812-12(2018) standard is utilized by manufacturers, testing labs, and regulatory bodies to ensure that eye protectors for off-road motor sports meet the highest quality and safety criteria. Typical use cases include:

  • Off-Road Motorcycling and Motocross: Protects eyes from debris and airborne particulates on tracks, trails, or rural terrains.
  • Snowmobiling: Shields the rider’s eyes from impacts due to ice, snow, and hard particles encountered in snowy environments.
  • Moped and Powersport Activities: Provides critical defense against road debris that may be kicked up during group or solo rides.

Following this standard assures end-users that the eye protectors are rigorously tested for impact resistance, optical quality, and durability-while also maintaining comfort and usability in harsh and variable conditions. Compliance with ASTM F2812-12(2018) reduces liability and promotes consumer confidence in safety equipment used in recreational and competitive motor sports.

Related Standards

Key standards referenced and related to ASTM F2812-12(2018) include:

  • ANSI Z87.1 – Occupational and Educational Eye and Face Protection Devices (for prescription eyewear and workplace hazards)
  • ANSI Z80.3 – Ophthalmics: Nonprescription Sunglasses and Fashion Eyewear Requirements (for optical quality and UV transmittance)
  • EN 168 – Personal Eye Protection: Non-Optical Test Methods (for test head forms and non-optical requirements)
  • ASTM D1003 – Test Method for Haze and Luminous Transmittance of Transparent Plastics

By adhering to these standards, manufacturers and end-users ensure eye protectors are effective and reliable, providing essential protection for sporting and recreational motor sports activities.

Keywords: ASTM F2812, goggle-type eye protectors, spectacle-type eye protectors, motor sports safety, impact resistance, off-road eye protection, snowmobile eyewear, motorcycle goggles, ASTM standards, eye injury prevention.
