FOREWORD

This document is a voluntary performance standard for chemical, biological, radiological and 

nuclear (CBRN) protective ensembles for use by law enforcement. It defines both performance 

requirements and the methods used to test performance. In order for an ensemble manufacturer

or other entity to claim that a particular CBRN protective ensemble model satisfies this National 

Institute of Justice (NIJ) standard, the model must be in compliance with this standard as 

determined in accordance with this document and the associated document, Law Enforcement 

CBRN Protective Ensemble Certification Program Requirements, NIJ CR-0116.00. Both this 

standard and the associated certification program requirements document are produced as a part 

of the Standards and Testing Program of the U.S. Department of Justice, Office of Justice 

Programs, NIJ, as is a third associated document, the Law Enforcement CBRN Protective 

Ensemble Selection and Application Guide, NIJ Guide-0116.00.

All requirements stated in this standard, including those that explicitly employ mandatory 

language (e.g., ―shall‖) are those necessary to satisfy the standard. Nothing in this document is 

intended to require or imply that commercially available CBRN protective ensembles for use by 

law enforcement must satisfy this standard.

This document is a performance and testing standard and, therefore, provides precise and 

detailed test methods. Portions of this standard are used with permission from the National Fire 

Protection Association (NFPA), and references to the NFPA documents listed below are cited

1. SCOPE, PURPOSE AND APPLICATION

1.1 Scope

1.1.1 This document is a voluntary standard. All requirements stated in this standard, 

including those that explicitly employ mandatory language (e.g., ―shall‖) are those 

necessary to satisfy the standard. Nothing in this document is intended to require or 

imply that commercially available chemical, biological, radiological and nuclear 

(CBRN) protective ensembles for use by law enforcement must satisfy this standard.

In order for an ensemble manufacturer or other entity to claim that a particular CBRN 

protective ensemble model satisfies this NIJ standard, however, the model must be 

found to comply with this standard as determined in accordance with this document 

and the associated document, Law Enforcement CBRN Protective Ensemble 

Certification Program Requirements, NIJ CR-0116.00. 

1.1.2 This standard specifies the minimum requirements for form and fit, performance, 

testing, documentation and labeling of CBRN protective ensembles intended to 

protect law enforcement personnel from CBRN hazards. CBRN hazards include 

chemical warfare agents (CWAs), toxic industrial chemicals (TICs), biological agents

and radiological and nuclear particulate hazards that may inflict bodily harm, 

incapacitation or death.

A

1.1.3 CBRN protective ensembles consist of four elements:

Garment covering the wearer’s upper and lower torso, arms, legs and head.

Hand protection elements covering the wearer’s wrists and hands.

Foot protection covering the wearer’s feet, ankles and lower legs.

Respiratory protection.

Figure 1 provides a pictorial representation of a CBRN protective ensemble and its 

elements.

Figure 1. CBRN Protective Ensemble and Its Elements
CBRN Protective Ensemble Standard for Law Enforcement

2

1.1.4 Although respiratory protection is a CBRN protective ensemble element, performance 

requirements for respiratory protection are addressed in other, non-NIJ standards and 

are not addressed in this standard. Requirements in this standard address the CBRN 

protective ensemble overall and three of the elements (excluding respiratory 

protection).

1.1.5 This standard specifies requirements for new, unworn law enforcement CBRN 

protective ensembles and ensemble elements.

1.1.6 This standard does not specify requirements for protection from ballistic threats, 

explosives or ionizing radiation.

1.1.7 This standard does not apply to any accessories, and all testing required in this 

standard shall be performed with no accessories attached. (See 3.2.1, Accessories.)

1.1.8 This standard shall not be understood as addressing all of the safety concerns 

associated with the use of CBRN protective ensembles and ensemble elements. Users 

of this standard should be aware of all safety and health issues associated with the use 

of CBRN protective ensembles. User information related to these issues is provided 

in Law Enforcement CBRN Protective Ensemble Selection and Application Guide,

NIJ Guide-0116.00.

1.1.9 This standard shall not be understood as addressing the safety concerns, if any, 

associated with the use of this standard by testing facilities.

1.1.10 No ensemble manufacturer or other entity shall claim compliance with only selected 

portions of this standard. The CBRN protective ensemble model shall meet all 

applicable stated requirements.

1.1.11 Nothing herein shall be understood to restrict any ensemble manufacturer from

exceeding the requirements of this standard.

1.1.12 As appropriate (e.g., for models that employ materials or forms of construction that 

were not anticipated when this standard was developed or are not addressed by this 

standard), NIJ may modify the test methods of the standard or establish new ones. 

1.2 Purpose

1.2.1 The purpose of this voluntary standard is to specify minimum requirements for 

CBRN protective ensembles worn by law enforcement personnel conducting law 

enforcement response operations at an incident involving suspected or identified 

CBRN hazards. It is recognized that the mission and associated requirements of law 

enforcement are unique within the first responder community and that a performance 

standard reflecting these requirements is essential.
CBRN Protective Ensemble Standard for Law Enforcement

3

1.2.2 The purpose of the test methods in this standard is to assess performance and should 

not be understood to specify performance levels for all situations and hazards to 

which law enforcement personnel may be exposed.

1.3 Application

1.3.1 This standard provides for four levels of CBRN protective ensembles that could be 

selected for protection of law enforcement personnel. The four levels are based on 

mission requirements, expected mission duration, durability requirements of different 

operations and activities, and hazards in the CBRN threat environments. 

1.3.2 The requirements for Law Enforcement Response Level 1 (LERL-1) CBRN 

protective ensemble models and ensemble elements apply to ensemble models and 

ensemble elements intended to provide limited protection to law enforcement 

personnel making tactical entry into environments involving CBRN hazards, 

conditions in which contaminant concentrations are unknown or are known to be at or 

above immediately dangerous to life and health (IDLH) levels requiring the use of a

self-contained breathing apparatus (SCBA), and flame and flash fire hazards. LERL-1 

ensembles are intended to withstand the rigorous use associated with tactical 

operations. These ensemble models are required to be tested against two CWAs and 

24 TICs that are representative of many chemical threats. 

1.3.3 The requirements for Law Enforcement Response Level 2 (LERL-2) CBRN 

protective ensemble models and ensemble elements apply to ensemble models and 

ensemble elements intended to provide limited protection to law enforcement 

personnel making tactical entry into environments involving CBRN hazards and 

conditions in which contaminant concentrations are unknown or are known to be at or 

above IDLH levels requiring the use of an SCBA. LERL-2 ensembles are intended to

withstand the rigorous use associated with tactical operations. These ensemble

models are required to be tested against the same two CWAs as LERL-1 ensemble

models and five TICs. 

1.3.4 The requirements for Law Enforcement Response Level 3 (LERL-3) CBRN 

protective ensemble models and ensemble elements apply to ensemble models and 

ensemble elements intended to provide limited protection to law enforcement 

personnel making tactical entry into environments involving CBRN hazards and 

conditions in which contaminant concentrations are known to be below IDLH levels 

permitting the use of an air purifying respirator (APR) or powered APR (PAPR). 

LERL-3 ensembles are intended to withstand the rigorous use associated with tactical 

operations. These ensemble models are required to be tested against the same CWAs 

and TICs as LERL-2 ensemble models.

1.3.5 The requirements for Law Enforcement Response Level 4 (LERL-4) CBRN 

protective ensemble models and ensemble elements apply to ensemble models and 

ensemble elements intended to provide limited protection to law enforcement 

personnel performing perimeter operations at incidents involving CBRN hazards and 

conditions in which contaminant concentrations are known to be below IDLH levels 
CBRN Protective Ensemble Standard for Law Enforcement

4

permitting the use of an APR or PAPR and where mission tasks require less stringent 

ensemble durability. These ensemble models are required to be tested against the 

same CWAs and TICs as LERL-2 and LERL-3 ensemble models. 

1.4 Units

1.4.1 In this standard, values for measurement are followed by an approximate equivalent 

in parentheses, but only the first stated value shall be regarded as the requirement.

ANNEX A. Acoustic Measurements and Calculations

Measurements

All measurements are one-third octave sound pressure level averages. The averaging time is 32 

seconds with a single stationary microphone position for each source. The third octaves from 50 

Hz to 10,000 Hz are used for the calculations.

Calculations

Take all of the sound pressure level measurements for each one-third octave and average them in 

the pressure domain. Use Equation 6 to convert all of the sound pressures levels (dB re: 20 uPa) 

to pressure levels in Pascals. Lpt is the sound pressure level in one-third octave bands. Use 

Equation 7 to average the pressure levels and convert them back to decibel levels. Pt is the 

pressure level in one-third octave bands. LApt is the average of the sound pressure levels in onethird octave bands.

Where n is the number of sources. 

The averaged sound pressure levels need to be corrected for background levels and checked to be 

sure that there was no contamination.

If the difference of the average and the background levels is between six and 10 decibels, use 

Equation 8 to correct the average sound pressure. Subtract the result of Equation 8 from the 

measured source sound pressure level as indicated in Equation 9.

If the difference of the average and the background levels is between two and six decibels, the 

background correction formula is still used but the data are marked with an asterisk to indicate 

contamination.

If the difference of the average and the background levels is less than two decibels, the data are 

marked with a double asterisk and the data are not corrected. The double asterisk indicates high 

levels of contamination. If any double asterisks are found then the background levels need to be 

lowered before testing can resume. LBt are the background levels in one-third octave bands. LAptB

are the average one-third octave sound pressure levels corrected for background.

Standards and Testing Program

The Standards and Testing Program is sponsored by the Office of Science and Technology of 

the National Institute of Justice (NIJ), Office of Justice Programs, U.S. Department of Justice.

The program responds to the mandate of the Homeland Security Act of 2002, which directed 

the Office of Science and Technology to establish and maintain performance standards in 

accordance with the National Technology Transfer and Advancement Act of 1995 (Public Law 

104–113) to test and evaluate law enforcement technologies that may be used by federal, state 

and local law enforcement agencies. The Homeland Security Act of 2002 also directed the 

Office of Science and Technology to establish and maintain a program to certify, validate

and mark or otherwise recognize law enforcement technology products that conform to the 

standards mentioned above.

The Standards and Testing Program is a basic and applied research effort that determines the 

technological needs of justice system agencies, sets minimum performance standards for 

specific devices, tests commercially available equipment against those standards, and 

disseminates the standards and the test results to criminal justice agencies nationally and 

internationally.

The Office of Law Enforcement Standards (OLES) at the National Institute of Standards and 

Technology develops voluntary national performance standards for compliance testing to 

ensure that individual items of equipment are suitable for use by criminal justice agencies. 

The standards are based upon laboratory testing and evaluation of representative samples of 

each item of equipment to determine the key attributes, develop test methods and establish 

minimum performance requirements for each essential attribute. In addition to the technical 

standards, OLES also produces technical reports and user guidelines that explain in 

nontechnical terms the capabilities of available equipment.

The National Law Enforcement and Corrections Technology Center (NLECTC), operated by a 

grantee, coordinates a national compliance testing program conducted by independent 

laboratories. The standards developed by OLES serve as performance benchmarks against 

which commercial equipment is measured.
