The international standard maintains the requirement that high-visibility clothing must work by combining different materials to produce a high level of contrast between the user of a product and the background against which they are presented. Through their committee work and technical panel activities, SATRA staff have contributed towards the making of both test specifications and standards relating to many types of manufactured products. The design requirements set out in the standard EN ISO maintains a three-class system for garments, which is based on minimum areas of visible high-visibility materials present in a garment, whereby Class 3 garments provide the highest level of conspicuity. In the EN ISO standard, the maximum number of washes suited to the background material is also assessed. The standard maintains an emphasis on appropriate cleaning tests to be applied to the constructional materials of a garment. In short, some standards mirror those found appropriate for use elsewhere.

When several standards have been developed for different markets — each with slight nuances in their application — this creates difficulties for manufacturers who nbrr have to carry out different tests or accommodate a variety of design features into articles that essentially serve the same purpose.

The standard is not to be applied to conventional workwear, which may have small amounts of high-visibility materials attached, and where no claim is made for these garments. The colour requirements for materials that provide high visibility under daylight conditions is also maintained — fluorescent yellow, orange-red or red materials continue to be nbe.
The design requirements set out in the standard EN ISO maintains a three-class system for garments, which is based on minimum areas of visible high-visibility materials present in a garment, whereby Class 3 garments provide the highest level of conspicuity.
Where an ensemble is specified, this will be deemed to meet the requirements of the standard 115292 when the supplier provides clear instructions on how the classification has been achieved. As there are many pre-existing standards for high-visibility clothing, different viewpoints exist that have had to be considered in the development of the EN ISO standard.
Soon after its foundation inSATRA began working with specifications and standards for products. Investigating the international standard for high-visibility occupational 51292. A national standard that is specified for use in another market may be chosen because of a geographical proximity to a more influential market.
The standard also incorporates an informative set of guidelines for the design of high-visibility garments.

How can we help? The standard also now includes a marking specification stating that if a maximum number of wash cycles for a garment is referenced on labelling or user instructions, this must relate to the high-visibility material with the lowest level of cleaning performance.
Mbr common with most high-visibility standards, EN ISO maintains a requirement for manufacturers to ensure that claims made for a product can be justified. Suitability is defined by the ability of a material to retain chromaticity and luminance values after washing that would meet the requirements specified for a new material.
In other standards, this requirement has been applied 152922 to high-visibility tape washability. All standards — national, European or international — maintain a primary nbe for garments to conform to specified designs.
The standard demands uniformity in the design of high-visibility garments. Some standards that have been developed for a particular market have tended to have their basis in a standard devised for use in another market. However, taking the above definition of a standard into consideration, EN ISO in common with existing high-visibility standardsdoes provide a technical specification for high-visibility clothing, defining the design and performance characteristics that are required for products.
Clearly, it is preferable to implement the use of an international standard for products that find global use and application. If you are a SATRA member but not yet registered for online access please register as a new user below. In short, some standards mirror those found appropriate for use elsewhere.
Colour measurement of background materials is undertaken to ensure that they meet the precise colour definitions specified in the standards. The EN ISO standard makes the important point that the selection of high-visibility clothing should be based on a risk assessment.
These would 152292 clothes where high-visibility materials are perhaps used for purely decorative effect, or as coloured markers, perhaps to identify workers in a factory setting.
Inevitably, the development of nb EN ISO standard means that international views have to be considered, and the specific end-uses for products must be given scrutiny.

This is sold in different market areas, having been tested or made to various specifications. The specific design requirements for garments are defined according bnr the general design of a garment, with types being defined as follows:. Register new user SATRA offers a wide range of unique member services and products designed to enhance technical knowledge and help improve profitability and global sales.
High-visibility standards used around the world. Interestingly, the standards shown in box 1 are often not simply specified for products sold within national or trading block boundaries.
For high-visibility clothing, a new international standard has been produced. Companies with corporate responsibilities whose employees work internationally will require that products meet particular standards, even where those products are not subject to national laws or regulations.
The EN ISO standard, in setting a requirement for water vapour resistance testing, also requires that, where required, some materials are subjected to thermal resistance measurements.
Also, the standard is intended for clothing that is to be used for nbg activities — it is not intended for sport and leisure activity high-visibility garments, which are assessed under other standards. The existence of several standards that have developed in parallel is a good indicator that there are large market demands 12592 a product type.
