Standards And Classifications
WATER DENSITY AND BREATHABILITY
Our products are made of either polyester/cotton/PVC, polyester/PU or a 3-layer fabric with membrane between them. The three different fabrics have different qualities, depending on use.
No textile is 100% waterproof. Water will penetrate the fabric as the water pressure increases. This is true for all textiles. In practice a product that is able to resist a water column of 15.000- 20.000 mm feels waterproof, as we only exceed this column in extreme situations.
Cotton/polyester/PVC, which we use, resists a water column of 15.000-20.000 mm.
This is also relevant for 3-layer products with membrane like for instance Medusa, or polyester coated with PU-membrane. The dilemma for the customer is deciding, on the one hand, how much water column a product should be able to resist and, on the other, the comfort and the breathability. Therefore, when choosing a product, it is crucial to consider for which purpose the product is needed.
Breathability is measured in mvp = moisture vapour perspiration. MVP tells you how much moisture can vaporise through the fabric per m2 per 24 hours. The higher the number, the higher the comfort.
Ocean’s products are quality and safety tested – and do not enter production before they have been approved. The tests are carried out by a recognised and independent Finnish testing institute.
Classification is determined by the minimum area of visible material in m2 and is calculated according to the below:
The minimum visible area requirements to achieve a garment classification are not to be reduced or compromised due to the presence of any logos, lettering, labels etc.
All safety wear from Ocean is EN ISO 20471 or EN 471 approved.
EN ISO 20471 and EN 471 are common European Hi-Visibility standards. This governs the specification of all certified work wear and rainwear, which is used in working environments, for example areas with traffic where it is important to be seen. Below we have tried to describe the most important guidelines, which should be the foundation of your choice of safety rainwear.
The standards have certain criteria to meet for employees working within hazardous/heavy traffic areas, most commonly in roadworks, railways and building and construction sites. Even if this work is only a small part of the working day, safety wear must be worn.
EN ISO 20471 and EN 471 standards are divided into 3 classifications. The classification describes how well the product is able to protect the user. The bigger the area of fluorescent fabric and reflective stripes, the higher the classification will be.
Should be worn by all working by the road, on railway lines and rescue workers, and also whilst working on and around buildings sites with machine traffic. As a rule, a set of work clothes fulfils the demands for class 3, when it’s worn together. A set of work clothes should be understood as a combination between a jacket and trousers/overall. Coveralls and certain jackets are also classified as Class 3.
Supervisors, who only check the work, should use class 2 wear. Class 2 wear is typically a high-vis waistcoat, a pair of overalls or a jacket.
Is typically trousers, which as the only safety wear must be worn by visitors. Although a high-vis waistcoat class 2 would be preferred with this (see below). Please be aware that workers in the area should always accompany visitors.
