EN ISO 20471 - High Visibility Clothing
This International Standard Specifies requirements for high visibility clothing, which is capable of visually signalling the user’s presence. The high visibility clothing is intended to provide conspicuity of the wearer in any light condition when viewed by the operators of vehicles or other mechanised equipment during daylight conditions and under illumination of headlights in the dark.
High Visibility clothing has a fluorescent surface, combined with reflective material that meets certification requirements in 3 different classes:
Class 3 - Highest Level
Required for any persons working on or near motorways/dual carriageways or airports. Must incorporate a minimum of 0.80m sq of background materials and 0.20m sq of retro-reflective materials. (4 metres of 5cm wide reflective tape)
Class 2 - Intermediate Level
Required for any person working on or near A and B Roads, also for delivery drivers. Must incorporate a minimum of 0.50m sq of background material and 0.13m sq of retro-reflective material. (2.60 metres of 5cm wide reflective tape)
Class 1 - Minimum Level
Minimum level of protection required for any persons working on a private road or to be sed in conjunction with a higher classed garment. Must incorporate a minimum of 0.14m sq of background material and 0.10m sq of retro-reflective material. (2 metres of 5cm wide reflective tape)
RIS-3279-TOM - Railway Group Standard
RIS imposes a higher concentration for high visibility orange fabric for railway workers. This increases the conspicuous nature of the fabric and ensures that the rail worker is more visible.
RIS-3279-TOM ISSUE 1
This is a railway group standard that specifies the minimum specification for high-visibility warning clothing in the UK rail industry, ensuring workers are conspicuous when on or near railway lines.
Is based on the European standard EN ISO 20471. It defines the minimum areas of high-visibility orange background materials to be used within a garment and the minimum level of photometric performance criteria for the reflective tape. The standard requires a reflective tape reading of ≥ 330 (cd/ lx.m2) however at Portwest we insist on a reading of ≥ 400 (cd/ lx.m2).
Imposes a higher concentration for high-visibility orange fabric for railway workers. This increases the conspicuous nature of the fabric and ensures the rail worker is more visible. A spectrophotometer is used to check the chromaticity (colour intensity) of the orange high-visibility fabric. Portwest check every roll of fabric to ensure the fabric meets the requirements of RIS-3279-TOM.
EN 343 is the European standard that applies to garments worn in adverse weather conditions
This standard specifies requirements and test methods applicable to the materials and seams of protective clothing against the influence of precipitation (e.g. rain, snowflakes), fog and ground humidity.
The standard provides for two performance parameters of which there are 4 levels with Class 4 offering the highest level of protection.
- X Water Penetration Resistance (Waterproofness) 4 Levels
- Y Water Vapour Resistance (Breathability) 4 Levels
- R Readymade Garment; Rain Tower Test (optional)
R may be replaced by an X if the test has not been carried out or is not suitable.
EN 342 - is the European standard that applies to garments worn in cold environments
This standard specifies requirements and test methods for the performance of clothing ensembles (i.e two-piece suits/coveralls) for protection against the effects of cold environments equal to or below -5°C.
There are three main parameters:
- A Thermal insulation (this is tested using a full-size moving mannequin & measures the amount of energy required to maintain warmth)
- B Air Permeability (This is a measure of how windproof the garment is), AP, Class 1-3 (where 3 is best)
- C Water penetration (waterproofness) Class 1-2 (where 2 is best); optional test
Wear Time
The manikin test measures the amount of energy required to maintain warmth. This result is expressed in square metres Kelvin per Watt (m2K/W) this result can be used to estimate the maximum wear time based on the activity level of the wearer, the temperature of the environment and insulation value of the garment.
