ANSI/ISEA Z89.1-2014 and CSA Z94.1-2015 voluntary industry standards establish
industrial helmet types and classes, providing performance and testing requirements.
These standards include specications for helmets designed to oer protection from top
and/or lateral impact.
Three classes included in these standards indicate helmet electrical insulation rating:
Class E (Electrical) – Helmets intended to reduce the danger of exposure to high-voltage
electrical conductors, proof-tested at 20,000 volts.
Class G (General) – Helmets intended to reduce the danger of exposure to low-voltage
electrical conductors, proof-tested at 2,200 volts.
Class C (Conductive) – Helmets do not provide protection from electrical conductors.
Industrial head protection test requirements per ANSI/ISEA Z89.1-2014 and CSA Z94.1-2015
are separated by helmet type: Type I helmets protect wearers from top impact, while Type II
helmets protect wearers from top and lateral impact. Test requirements for ANSI/ISEA Z89.1-
2014 and CSA Z94.1-2015 are available from the Industrial Safety Equipment Association
(www.safetyequipment.org) and www.CSA.ca, respectively.
In addition to three non-mandatory tests for reverse donning [ ], lower temperature
[LT] and high-visibility [HV], the ANSI/ISEA Z89.1-2014 standard also includes these
provisions:
n Section 5: Accessories and Replacement Components
Revised standard includes language to further support the premise that accessory/
component manufacturers are responsible for proving that their products do not
cause helmets to fail.
n Section 6: Instructions and Markings
Clarication language was added to help customers understand that “useful service
life” for helmets is not required by the Standard, although helmet manufacturers
may choose to include it.
n Section 7.3.3 Higher Temperatures (HT)
Revision enables additional protection in response to needs of users who may
work within hot environments. Optional preconditioning at higher temperatures
of 60°C ± 2°C (140°F ± 3.6°F) has been added. (In the 2009 Standard, temperature
conditioning was 48.8°C ± 2°C (120°F ± 3.6°F).) If a helmet has been
pre-conditioned to 60°C ± 2°C (140°F ± 3.6°F), the helmet will be marked as HT.
In addition, new updates allow for exibility and inclusion of emerging and current
best manufacturing materials for higher temperature protection.
NOTE: the Standard does not address pre-conditioning that could be needed for temperature and
radiant heat extremes. To ensure that you have the proper head protection level needed for your
specic heat application, check with the manufacturer for stated usage of any helmet.
Non-Mandatory
ANSI/ISEA Z89.1-2014 Tests
Reverse Donning [ ]
To enable a helmet to be worn in
reverse, or a swing ratchet suspension
to be used in a helmet, that particular
helmet must be marked with the
“double-arrowed circle” to indicate that
it meets the non-mandatory reverse
donning test.
Lower Temperature [LT]
The traditional low temperature test
for a helmet is -18°C or 0°F. Helmets
that meet ANSI Z89.1 requirements
for LOWER temperatures (-30°C or
-22°F) can be marked with LT by the
manufacturer.
High-Visibility [HV]
Helmets that meet non-mandatory
requirements for high-visibility, including
special tests forchromaticity and
luminescence for added visibility, can be
marked with HV by the manufacturer.
Higher Temperature [HT]
The traditional pre-conditioning
temperature test for a helmet is 48.8°C
± 2°C (120°F ± 3.6°F). Helmets that
meet ANSI Z89.1 requirements for
HIGHER temperatures pre-conditioned
to 60°C ± 2°C (140°F ± 3.6°F) can be
marked with HT by the manufacturer.
HT does not indicate pre-conditioning
that could be needed to validate
temperature and radiant heat extremes.
