HIGH VISIBILITY & TTMC-W STANDARDS

 

AS/NZS 1906.4:2010 - High visibility materials for safety garments

This standard specifies minimum colour and luminance requirements for fluorescent (F) or non-fluorescent (NF) background (compliant) materials and retro-reflective material (reflective tape) as used in the manufacture of garments for high risk applications.

“Class F” (fluorescent background material):

Refers to Fluorescent fabrics which have fluoro pigments. These include all our Safety Vests, Polo’s, Polyester/Cotton Shirts and Rainwear. Our Fluoro Yellow and Fluoro Orange Polycotton Protex Overalls also meet “Class F”. 

“Class NF” (Non—fluorescent background material):

All 100% Cotton Overalls, our natural fibres CTPCNLW and FTPCNLW, the Modacrylic FEPVC and FJPVC, and the 100% cotton Shirts are “Class NF” (Non—fluorescent background material). In general, natural fibres are not capable of taking a fluorescent pigment. The main difference is Class F garments have to meet a lot higher minimum luminance level than Class NF garments.

 

AS/NZS 4602:1:2011 – Garments for high risk applications

This standard specifies the design of garments in day only, night only and day/night situations. This specifies the minimum area of fluorescent or non-fluorescent background (compliant) materials present, including fabric, retro reflective tape for night visibility garments, and design and colours for day and night garments.

This standard specifies requirements for clothing intended to provide visibility of the user in high risk applications under any light conditions by day and under illumination by vehicle headlights in the dark (24 hours visibility). Effective visibility is to be provided by compliant fabric and reflective stripes.

Day only use: A Day only compliant garment must have a minimum 0.2m² of compliant orange or yellow material on both the front & back that completely encircles the upper torso excluding sleeves and any non complaint fabric collars & plackets.

Day/Night use: A Day/Night compliant garment must have a minimum 0.2m² of compliant orange or yellow material on both the front & back that completely encircles the upper torso excluding sleeves and any non complaint fabric collars & placket (must be visible - fabric covered by silver retro reflective tape is excluded). Retro-reflective material on the front and the back of the garment must comply within the design specified in the standard . This retro-reflective material must also be a minimum 50mm wide.

Night use: A Night compliant garment must include  Retro-reflective material on the front and the back of the garment within the design parameters  specified in the standard . This retro-reflective material must also be a minimum 50mm wide.

 

NZTA code of practice (CoPTTM) Temporary Traffic Management Control - Wet (TTMC-W) use:

NZTA has a Code of Practice which specifies the standard of safety garment that a worker must wear while working in or close to hazardous traffic areas. The Temporary Traffic Management Control Code of Practice (CoPTTM) states that each garment must include a certain area of fluorescent orange fabric, and a specific belt and braces configuration of 50mm wide retro-reflective tape. This CoPTTM covers both the compliancy of the design and the high visibility and retro-reflective material. A whole range of garments are specified, including vests, overalls, rainwear, shirts and polo’s.

Vests and some other miscellaneous garments (shirts and polo’s): Must have an additional reflectorised tail (must be 150mm longer than the front) on the rear of the garment. They must have a minimum 0.21m2 of compliant orange material on the front and 0.27m2 on the back including tail. Sleeves, non compliant collars and plackets are excluded. Garments and reflective braces must be a specific length for a size S.

Overalls: Must have a minimum of 0.3m2 of compliant orange material on both the front and back of the upper torso excluding sleeves and  non compliant collars. This must extend to a point above the knee .Single or double hoops of retro-reflective tape must be added to both the sleeves and legs. Reflective braces must be a specific length for a size S.

Long Sleeve Coat: Must have a minimum of 0.3m2 of compliant orange material on both the front and back of the upper torso excluding sleeves and  non compliant collars. Single or double hoops of retro-reflective tape must be added to the sleeves. Long Sleeve Coat and reflective braces must be a specific length for a size S.

As part of the CoPTTM, manufacturers are required to test and certify their garments at an NZTA approved testing laboratory. New compliance letters TTMC-W (Temporary Traffic Management Control – Wet) must be included on the compliant garments label to confirm that the garment meets the requirements. The fluorescent orange fabric used with the TTMC-W garments must comply to a ‘Wet’ luminance test (hence the ‘-W’ in TTMC-W). The wet test means that the fluorescent orange fabric must still achieve a certain luminance level, after influence of rainfall.

As of 31st January 2014, it will also be compulsory for NZTA Transit garments to comply to the new CoPTTM standard.

Make sure your garment has the TTMC-W label, and is tested and certified.

NZFOA Forestry Standard - Industry Approved Guidelines for clothing for forestry use (Unofficial NZ Standard)

This guideline specifies the minimum acceptable design standards for garments intended for use within New Zealand commercial forest environments. The garment must be made from a Fluoro Yellow or Fluoro Orange material that is compliant to AS/NZS 1906.4.

FID (Forest Industries Day time): Requires a minimum area of 0.06m² of fluoro material on both the front and back upper torso. Each solid block of fluoro grid must not be less than 15cm² with no dimensions less than 1cm of the solid block.

FIND (Forest Industries Day and Night): In addition to the above, a minimum of 150cm² of retro-reflective material is required on both the front and back upper torso.
