TTMC-W17 STANDARDS EXPLAINED
CODE OF PRACTICE FOR TEMPORARY TRAFFIC
MANAGEMENT (COPTTM) - TTMC-W17
CoPTTM describes best practice for the safe and efficient
management and operation of temporary traffic management
(TTM) on all roads in New Zealand.
The Waka Kotahi (NZTA) CoPTTM specifies two main colours
with regards to use on New Zealand roads;
• Yellow: Garments for site traffic management supervisors STMS; and
• Orange: Garments for all wearers other than supervisors.
STAYING COMPLIANT IN TTMC-W17 GARMENTS
• TTMC-W17 garments must not display any lettering/
symbols/logos on any compliant high visibility material
except within an area located on the wearer’s upper front left
side of the garment. The maximum area permitted is
7500mm2 (eg 100mm x 75mm).
• Garment designs that include a clear plastic pocket or
similar must locate this pocket within the described
maximum 7500mm2.
• Where required for related safety reasons a fabrics technical
recognition I.D. may be added in an area not exceeding
30mm x 30mm (900mm2) to the wearer’s upper front right
side of a garment.
• A manufacturer's label to a maximum size of 50mm x 20mm
may be sewn or printed on non-compliant material on the
lower sleeve or leg.
• Any buttons, domes or similar closure devices that are
placed on compliant material must match the colour of
the garments.
STMS GARMENTS
• The STMS sleeveless vest enables the person responsible at
a worksite to be readily identified.
• The background material colour must be fluorescent yellow.
• STMS garments are limited to the STMS logo located on the
upper front left side of the garment and as specified on the
back of the garment and the technical recognition I.D. as
appropriate. Other logos or labels may not be added.
AS/NZS 4602.1:2011 - HIGH VISIBILITY SAFETY
GARMENTS STANDARD
AS/NZS 4602.1:2011 is a joint Australian and New Zealand
standard covering high visibility safety garments.
The standard specifies visual requirements of hi-vis safety
garments, and refers to AS/NZS 1906.4:2010 for fabric and
tape used in the products.

AS/NZS 4602.1:2011 + AMDT 2:2020 CLASS DN
CHANGE FROM HRC TO PPE
ISO 11611:2015
Class DN are garments designed for day and/or night time use.
These garments are the most common and are a combination
of compliant background material and retro-reflective tape.
You may have noticed, in our communication and labelling, a
change from HRC to PPE, on the Arcguard range. Most obvious
is the change to the woven badge on Arcguard garments that
denotes the Arc Rating and the corresponding category. This
is because the standard that sets these categories has had an
update. This standard is NFPA 70E.
Protective clothing for use in welding and allied processes.
This standard specifies minimum basic safety requirements
and test methods for protective clothing which is intended to
protect the wearer against spatter (small splashes of molten
metal), short contact time with flame, radiant heat from an
electric arc used for welding and allied processes. It also
minimizes the possibility of electrical shock by short-term,
accidental contact with live electrical conductors in normal
conditions of welding.
AS/NZS 4602.1:2011 + AMDT 2:2020 CLASS D
Class D are garments designed for daytime use only. These
garments have compliant background material, but no retroreflective tape.
AS/NZS 4602.1:2011 + AMDT 2:2020 CLASS N
Class N are garments designed for night time use only. Class
N has no fluorescent fabric but does have retro-reflective tape.
Class N provides the wearer with high visibility at night when
viewed under retro-reflected light such as vehicle headlights.
AS/NZS 1906.4:2010 - HIGH VISIBILITY MATERIALS FOR
SAFETY GARMENTS
This standard specifies the requirements for high-visibility
materials for outdoor daytime use, or retro-reflective materials
for use at night or in other dark conditions. Designed to be
worn in situations where the wearer needs to be highly visible.
The standard specifies minimum colour and luminance
requirements for fluorescent (F), non-fluorescent (NF)
and retro-reflective materials.
CLASS F (FLUORESCENT BACKGROUND MATERIAL)
Refers to fluorescent fabrics which have the ability to retain
fluorescent pigment. Often, but not limited to, man-made
fibres such as polyester and plastic coatings.
CLASS NF (NON-FLUORESCENT BACKGROUND MATERIAL)
Refers to Non-fluorescent background material. Class NF
materials do not have the fluorescent properties of class F
materials and will provide reduced luminance for the wearer.
Where for safety reasons a garment must be made from
natural fibre which is unable to retain fluorescent colour class
NF fabric can be used. These are often, but not limited to,
cotton and FR blends.
AS/NZS 4399:2017 - SUN PROTECTIVE CLOTHING
Products have been tested to the Australian/New Zealand
standard for sun protective clothing AS/NZS 4399:2017
(Ultraviolet Protection Factor).
EN 343 PROTECTIVE CLOTHING - PROTECTION AGAINST RAIN
EN 343 is a European Standard for protective clothing that
outlines a minimum level of protection against wet weather,
and is tested for its ability to withstand heavy water pressure
and for its breathability.
NFPA 70E
Standard for Electrical Safety in the Workplace. NFPA 70E is
a globally used American consensus standard that addresses
electrical safety in the workplace. It explains how to protect
electrical workers against electrical hazards. This standard is
revised every three years.
One revision you will start to notice is the change from HRC
to PPE. In 2015 NFPA 70E eliminated the term Hazard Risk
Category (HRC) and replaced it with Personal Protection
Equipment Category. This can be shortened to CAT or PPE.
Arcguard uses PPE.
Most importantly the category levels remain the same. The
minimum arc rating for PPE is the same as HRC. The change
is merely a name to more accurately describe the function of
the categories.

ASTM F1959/F1959M AND IEC 61482-1-1
Standard Test Method for Determining the Arc Rating of
Materials for Clothing. This standard test method is used to
measure the arc rating of materials intended for use as flame
resistant clothing for workers exposed to electric arcs.
ISO 11612:2015
Protective clothing - Clothing to protect against heat
and flame - Minimum performance requirements. These
performance requirements are applicable to protective clothing
where there is a need for clothing with limited flame spread
properties and where the user can be exposed to radiant/
convective/contact heat or to molten metal splashes.
EN 1149:2008
Protective clothing. Electrostatic properties. Material
performance and design requirements. The EN 1149
standard specifies a test method for materials to be used
in the production of protective clothing with electrostatic
dissipation for preventing incendiary discharge.
EN 1149-3:2008
Protective clothing. Electrostatic properties. Test methods
for measurement of charge decay. The fabric releases its
electrostatic charge to the air therefore won’t conduct it to
the user of the clothing. The standard contains a test method
in which the amount of time it takes to dissipate electrostatic
charge from the surface of the clothing material.
EN 1149-5:2008
Electrostatic properties. Performance requirements and
material design. This is the European Standard for garments
that protect against electrostatic discharge in areas where
there is a risk of explosion and where there is a risk that the
garments could create sparks (source of ignition), which in
turn could ignite explosive materials.
ISO 14116:2015
Protective clothing - Protection against flame - Limited
flame spread materials, material assemblies and clothing.
Garments complying to this standard protect workers from
occasional and brief contact with small igniting flames, in
circumstances where there is no heat hazard from flame or
other source. The standard specifies limited flame spread
properties in order to reduce the possibility of the clothing
burning and thereby itself becoming the hazard.
