FACT SHEET TESTING OF HIGH-VISIBILITY SAFETY GARMENTS ­ PART II Background This is the second article in a series relating to information about high-visibility garments. The first of these articles looked at the design aspects, this article focuses on the materials used in these garments. The Standard for High-Visibility Safety Garments AS/NZS 1906.4:2010 is the joint Australian and New Zealand standard covering the materials used in high visibility safety garments. This standard is also referred to in AS/NZS 4602.1:2011 which relates to product design. Application of the Standard There are two specifications relating to materials: the background material used in Day and Day/Night garments the retroreflective tape used in the Day/Night and Night garments The background materials can be fluorescent ("F") or Non-Fluorescent ("NF"). Fluorescent materials are most efficient in day light when there is an appreciable amount on UV (ultraviolet) in the light. Artificial night time lighting contains little or no UV, so these background colours have limited visibility in night lighting. The retroreflective tapes are only effective at night time. Tests and Specifications Background Material Specifications for the colour space and luminance (brightness) are provided in the AS/NZS 1906.4:2010. The colour space is divided into 2 main classes - yellow and orange-red, with further divisions for certain applications. The colour space is illustrated on a graph, using x and y co-ordinates, an example of which is shown on the right. The most common and most effective colours are fabrics dyed or printed with fluorescent dyes or pigments (class F). However there is provision in the standard for the use of non fluorescent colour (class NF) which is applicable for natural fibres. The specification of luminance is lowered accordingly and users need to be aware that such garments may not have the same long distance visibility as fluorescent materials. Measurements are conducted under a standard light source (D65) with the material in a dry state for all garments. Fabrics intended for wet weather use are also tested wet. Wet luminance allowance is 85% of the dry luminance, reflecting the dulling associated with water. Additional tests are also mandatory within AS/NZS 1906.4:2010, with minimum specifications for colour and luminance after light exposure and colour fastness to washing and perspiration measurements of the durability of the colour in the material (not of the material itself). FACT SHEET Retroreflective Tape Retroreflective tape is the material that gives night time visibility. These tapes reflect any light shining onto them back to the light source. They are most effective in night time driving when the driver is approximately at the same angle of viewing as the light source. Retroreflective tape comes in two varieties - Class R or Class RF. Class R tape are those where the colour is not relevant (this is most often silver, and used in many applications). Examples of Class R tapes are shown on the right in three different garments. Class RF tapes are a combined-performance tape ­ these are retroreflective and include fluorescent colours in the tape itself (not just the background material). The widest application of RF tapes is in the fire service industry, an example of which is shown on the left. The tapes are tested for minimum brightness and are measured at various angles to ensure their effectiveness. Other factors relating to their durability are specified as part of the standard. These tests include brightness after light exposure, washing, abrasion, raised temperature and rainfall, along with a check on flexing and cold cracking. Advice on High-Visibility Safety Garment Testing The variety of tests conducted within AS/NZS 1906.4:2010, together with the design standard for such garments (AS/NZS 4602.1:2011 ­ discussed in a previous Fact Sheet), ensures a complete performance analysis of highvisibility garments. NZWTA Ltd has a comprehensive understanding of the standards involved in high-visibility garment testing and can provide a report on the conformance to these standards.

FACT SHEET CHEMICAL TREATMENTS IN SCOURED WOOL ­ THE ALKALI SOLUBILITY TEST Background Scouring wool can often involve a number of chemical treatments in order to standardise its colour or provide additional properties to improve its intended productuse. Some of these chemicals may cause damage to the wool, the likes of which is not necessarily obvious to the eye. Tests for damage are based around the principle that wool shows an increased solubility in alkaline solutions when attacked by oxidising or reducing agents, acids, or exposure to heat or light. Most testing on scoured wool is conducted to quantify the damage caused by hydrogen peroxide bleaching, a chemical regularly used to produce a whiter visual appearance for the wool. The Alkali Solubility Standard This test is conducted according to test method IWTO DTM4. It involves the treatment of a dry wool sample in sodium hydroxide under controlled conditions of time, temperature and volume. The alkali solubility is calculated as the loss of the mass of the treated specimen expressed as a percentage of its oven dry mass. The results reported are: (a) The pH of the aqueous extract (b) The individual alkali solubility for each specimen and the mean result for the sample The test is most useful when an untreated control sample is available and when the nature of the treatment of the sample under test is known. When the sample has been treated by two agencies having opposite effects on the solubility, the interpretation of the results even when an untreated control sample is available, is difficult and may be misleading. The test does not provide an absolute measure of damage, instead is useful as an indicator of relative levels of damage. Fig 1: Samples sitting in a water bath during test preparation Application of the Standard The alkali solubility of crossbred wool that has not been chemically modified to any significant extent usually lies within the range of 11 ­ 14%. Evidence suggests that fine wool (e.g. Merino wool) may normally exhibit higher solubility (up to 18%) due to the greater surface area exposed to the treatment. Wools subjected to moderate levels of peroxide during the scouring process can produce alkali solubility levels exceeding 20%. Heavily bleached wools can produce results over 30%.

FACT SHEET TESTING OF HIGHVISIBILITY SAFETY GARMENTS ­ PART III NZ TRANSPORT AGENCY SPECIFICATIONS Background This is the third article in a series relating to information about highvisibility garments. The first two articles discussed requirements relating to design and materials used in these garments. This article provides details relating to additional specifications for garments as required by the New Zealand Transport Agency (NZTA). NZTA Specifications for HighVisibility Safety Garments Specifications for all temporary equipment (e.g. signs, signals, garments and delineation devices) on roads under the jurisdiction of the NZTA are published in Section B of the Code of Practice for Temporary Traffic Management (COPTTM). This is Part 8 of the NZTA Traffic Control Devices (TCD) manual. The relevant section of the COPTTM is available for download at the NZTA website and is provided below: www.nzta.govt.nz/resources/codetemptrafficmanagement/docs/copttm sectionb4thed.pdf The NZTA specification is based around AS/NZ4206.1:2011 and AS/NZS1906.4:2010, except with more detail and additional requirements. Figure 1: Sleeveless vest Retroreflective tape and highvisibility background material must conform to AS/NZS1906.4:2010. Application of the Specification There are four garment design categories sleeveless vests, long sleeves coats, overalls and miscellaneous (e.g. polo shirts, woven shirts, polar fleeces). All of these designs are closely specified in terms of garment length, shirt tails, tape length, tape configuration and logos. Figure 2: Garment for Site Traffic Figure 3: Overalls Management Supervisors The 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 Compliant garments with the COPTTM must be labeled with the letters `TTMCW'. TESTING OF HIGHVISIBILITY SAFETY GARMENTS ­ PART III, Fact Sheet ­ January 2014 FACT SHEET The key differences between the general standards (AS/NZS4602.1:2011 and AS/NZS1906.4:2010) and the NZTA COPTTM specification are summarised below: AS/NZS 4602.1:2011 & AS/NZS 1906.4:2010 Minimum 0.2 m2 of the background hivisibility material on both front and back for all garment types NZTA COPTTM Specification Minimum area of background hivisibility material is specified for each garment type for both and front. The amount varies per garment type. In all cases it is larger than 0.2 m2 The measurement is carried out using a hatched rectangle that extends over a larger area to the bottom of vest coats and miscellaneous garments and to the upper leg hoop of overalls The colour of the high visibility background material is measured both wet and dry before and after light exposure The permitted front opening may be no wider than 25 mm The design for all garments is specified Specific requirements for STMS garments in terms of background high visibility material colour and STMS label Logos are restricted by size and location. STMS garments are restricted to the STMS label and technical recognition ID Only DN garments are included The tape configuration is specified belt and braces with shirt tail strip. The tape length and distance between braces is specified Size S is tested and all other garments (larger or smaller) must be in proportion with the compliant garment The standard is specific on the inclusions of other colours on the torso except for the tape, front opening and logos The measurement is carried out using a hatched rectangle that goes to the waist for all garments regardless of design Only wet weather garments are measured wet before and after light exposure The permitted front opening may be no wider than 50 mm The design for all garments is not detailed STMS garments are not specified The size of any logos has to be deducted from any background material measurements and must not interfere with the continuity of the background material D, N and DN garments are permitted Different configurations are allowed. The dimensions are not closely specified Any size can be tested. Size S that do not have 0.2m2 are compliant if the background material goes to the waist The standard allows flexibility on the inclusion of additional items such as pockets, logos and ventilation gussets. Advice on HighVisibility Safety Garment Testing The NZTA Code of Practice for Temporary Traffic Management and the two key Standards for highvisibility garments (AS/NZS 4602.1:2011 for garment design and AS/NZS 1906.4:2010 for background materials and retro reflective tape) provide a significant amount of detail and specification for manufacturers and users. NZWTA Ltd has a comprehensive understanding of the standards involved in highvisibility garment testing and can provide a report on the conformance to these standards.
