All samples shall be taken at random. Tests shall be carried out in the sequence and according to the sample sizes specified in Figure 3.1. Photometric， chromaticity and luminance testing shall be carried out for all colours. All other tests may be completed for the white example of a design if the only variation is colour and retroreflectivity.
The following criteria shall apply:
(a) If no more than one of the samples fail to meet the minimum CIL requirement by 15% or less at one of the specified viewing geometries, the sample shall be deemed to conform.
(b) If no more than one of the samples fail to meet the minimum CIL requirement by 15% or less, at more than one of the specified viewing geometries, a new sample shall be taken for photometric testing.
(c) If no more than one of the samples fail to meet the minimum CIL requirement by more than 15% at any of the specified viewing geometries a new sample shall be taken for photometric testing.
The performance requirements for the marker body of both Category D non-retroreflective markers and Category G retroreflective markers shall be the same.
The markers should be constructed using materials that will sustain the continual impacts of traffic, resist the incursion of water and degradation caused by UV. The exterior of the marker shall not contain any projections which may be a hazard to tyres.The base shall be free of any substance or coating that may reduce its ability to bond to the adhesive recommended by the manufacturer.
The base of a marker which is not designed to be inset into the pavement shall be flat within an overall tolerance 1.5 mm. If the base has an embossed, ribbed or cellular pattern, this requirement shall apply to an imaginary surface passing through all low points of the pattern.The design of the marker should be such that it may be readily cleaned, its surface design unimpaired by protuberances or edges that may increase grime build-up. In cases of dispute, this should be determined by measuring CIL before and after washing.AS NZS 1906.3 pdf free download.
