This

9、seventh revision of the American National Standard for Industrial Head Protection, ANSI/ISEA Z89.1-2014 represents an effort to accommodate characteristics of industrial head protection that end-users identified as being important as work environments change and emerging hazards are identified. This

10、 edition was prepared by the ISEA Head Protection Group whose current members include: 3M Company, Bullard, ERB Industries, Gateway Safety, Honeywell Safety Products, Kimberly-Clark Professional, MSA Safety, OccuNomix International, Protective Industrial Products Inc., and Sellstrom Manufacturing Co

11、. The core performance requirements remain unchanged. However, this updated version incorporates optional preconditioning at higher temperatures than the standard test temperatures. Head protection devices that meet the applicable product performance criteria after having been exposed to these highe

12、r temperatures will bear a unique mark indicating such, to provide easy identification to the user. This standard was processed and approved using consensus procedures prescribed by the American National Standards Institute.

23、I/ISEA Z89.1-2014 Page 1 American National Standard for Industrial Head Protection 1 Scope, Purpose and Limitations 1.1 Scope This standard establishes minimum performance and labeling requirements for protective helmets used in industrial and occupational settings under normal temperature condition

24、s and optionally at high and low temperatures and when worn in the reversed position. It also includes requirements for high-visibility helmets and specifies test methods for evaluating all requirements. Helmets conforming to the requirements of this standard are designated both by Type (based on lo

25、cation of impact force) and Class (based on electrical insulation) as well as any optional feature. This standard does not cover bump caps, firefighting helmets or head protection devices used in recreational activities. User cautions and recommendations on use and care of helmets are given in Appen

26、dix A of this standard. 1.2 Purpose This standard establishes minimum performance requirements for protective helmets that reduce the forces of impact and penetration and that may provide protection from electric shock (not arc flash). 1.3 Limitations Protective helmets reduce the amount of force fr

27、om an impact blow but cannot provide complete head protection from severe impact and penetration. Helmets that meet this standard provide limited protection but should be effective against small tools, small pieces of wood, bolts, nuts, rivets, sparks and similar hazards. The use of protective helme

28、ts should never be viewed as a substitute for good safety practices and engineering controls. Alterations, attachments, or additions of accessories may affect the performance of the helmet. Helmets are designed to provide protection above the test lines, which are clearly defined in the standard. He

29、lmets may extend below the test lines for styling or practical purposes but no protection is to be implied below the test lines. 1.4 Units and Tolerances In this standard, SI units of measurement are followed by an approximate imperial equivalent in parenthesis. Only the SI value shall be regarded a

30、s the requirement. 2 Compliance Any statement(s) of compliance with this standard shall mean that the product meets all applicable performance and labeling requirements for the Type and Class. It is specifically intended that partial utilization of this standard is prohibited. 3 Definitions accessor

31、y: A device intended to be mounted on or used with protective helmets. (See Section 5) apex: The point on the outer surface of the shell coincident with the vertical axis of the headform when the helmet is mounted in the as-worn position according to the manufacturers instructions. basic plane: A pl

32、ane at the level of the external auditory meatus (external ear opening) and the inferior margin of the orbit (lower edge of the eye socket). chin strap: A strap which fits under the chin and is attached to the helmet. component: A functional part of a complete device addressed by the performance req

33、uirements of this standard. crown straps: The part of the suspension that passes over the head. dynamic test line (DTL): A test line used as a boundary for conducting impact energy attenuation and off-center penetration tests.

38、etic energy of impact. reference plane: A plane at a given distance above and parallel to the basic plane. reference headform: A measuring device contoured to specified dimensions with surface markings indicating the locations of the basic, midsagittal and reference planes, as well as any required t

39、est lines. shall: In this standard, use of the word “shall“ indicates a mandatory requirement. shell: The part of a helmet which includes the outermost surface. should: In this standard, use of the word “should“ indicates a recommendation. suspension: The portion of the harness which is designed to

40、act as an energy-absorbing mechanism. It may consist of crown straps, protective padding, or a similar mechanism. static test line (STL): A test line used as a boundary for conducting electrical insulation, flammability tests and for mounting for the force transmission test. test line: A line or com

41、bination of lines marked on a reference headform used to provide limits or a boundary beyond which protection is not considered. test plaque: A sample of the helmet or representative shell material with a thickness of 3 mm 0.5 mm (0.12 in. 0.02 in.). 4 Types and Classes Protective helmets are descri

42、bed by impact type and electrical class. All protective helmets shall meet either Type I or Type II requirements. All helmets shall be further classified as meeting Class G, Class E, or Class C electrical requirements. 4.1 Impact Types 4.1.1 Type I Type I helmets are intended to reduce the force of

43、impact resulting from a blow only to the top of the head. 4.1.2 Type II Type II helmets are intended to reduce the force of impact resulting from a blow to the top or sides of the head. 4.2 Electrical Classes 4.2.1 Class G (General) Class G helmets are intended to reduce the danger of contact with l

44、ow voltage conductors. Test samples shall be proof-tested at 2200 volts (phase to ground). This voltage is not intended as an indication of the voltage at which the helmet protects the wearer. ANSI/ISEA Z89.1-2014 Page 3 4.2.2 Class E (Electrical) Class E helmets are intended to reduce the danger of

45、 contact with higher voltage conductors. Test samples are proof-tested at 20,000 volts (phase to ground). This voltage is not intended as an indication of the voltage at which the helmet protects the wearer. 4.2.3 Class C (Conductive) Class C helmets are not intended to provide protection against co

46、ntact with electrical hazards. 5 Accessories and Replacement Components Accessories or replacement components, when installed, shall not cause the helmet to fail the requirements of this standard. The entity claiming that an accessory or replacement component, when installed, does not cause the helm

47、et to fail the requirements of this standard is responsible for providing justification upon request. 6 Instructions and Marking 6.1 Each helmet shall be accompanied by manufacturers instructions explaining the application(s) of use, proper method of size adjustment and fitting (including, if applic

48、able, reverse wearing) and, guidelines for care and useful service life. NOTE: Useful service life guidelines are intended to provide the user with information that certain conditions may affect a specific helmets continued protection over time. A specific service life, defined in terms of number of

49、 years, is not required though individual manufacturers may choose to include such information for their respective helmets. 6.2 Each helmet shall bear permanent markings in at least 1.5 mm (0.06 in.) high letters stating the following information: a. Name or identification mark of the manufacturer. b. The date of manufacture. c. The American National Standard designation, ANSI/ISEA Z89.1-2014. d. The applicable Type and Class designations, followed by applicable optional criteria markings; e. The approximate headsize range (see Table 2). 6.3 If optional performance feature
