Flap Pockets

In order to comply with EN ISO 11611 all external pockets must be flapped, except for side pockets below the waist which do not extend more than ten degrees forward of the seam.

Rule Pockets

A single rule pocket with an opening not greater than 75mm is permitted behind the side seam on one or both legs.

Tensile and Tear Strength

To meet EN ISO 11611 tensile strength must be at least 400N and tear strength must be at least 15N for class 1 and 20N for class 2.

For example:

Portwest's winning FR50 style has a tensile strength value of at least 500N and tear strength of at least 25N after 50 washes.

EN342 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

(Example to the left refers to the Portwest Hi-Vis Bomber Jacket (S463) test results)

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.

For example (see chart to the left):

A person wearing the Portwest Hi-Vis Bomber Jacket (S463) performing light activity can withstand -2°C for 8hrs and -18°C for 1hr. A person performing Medium activity can withstand -18°C for 8hrs and -36°C for 1hr.

Protection against...

This international standard specifies minimum basic safety requirements and test methods for protective clothing for use in welding and allied processes (excluding hand protection). There are two classes with specific performance requirements.

Class 1 Level Protection

Class 1 is protection against less hazardous welding techniques and situations, causing lower levels of spatter and radiant heat.

Class 2 Level Protection

Class 2 is protection against more hazardous welding techniques and situations, causing higher levels of spatter and radiant heat.

The EN ISO 11611: standard has the following parameters:

• Tensile Strength
• Tear strength
• Busting strength
• Seam strength
• Dimensional change
• Requirements of leather
• Limited Flame Spread (A1 + A2)
• Molten Droplets
• Heat Transfer (radiation)
• Electrical resistance

This European standard is part of a series of standards for test methods and requirements for electrostatic properties of protective clothing.

The standard specifies material and design requirements for garments used as part of a total earthed system, to avoid incendiary discharges.

The requirements may not be sufficient in oxygen enriched flammable atmospheres.

This European Standard is not applicable for specifying protection against main voltages.

EN 1149-1:

Test method for measurement of surface resistivity. Surface resistance measures the conductivity between two points on the surface of a fabric. The lower the resistance the higher the conductivity, resulting in charge going to earth.

EN 1149-2:

Test method for measurement of the electrical resistance through a material (vertical resistance). This is the level of conductivity when measured through the depth of a fabric.

EN 1149-3:

Test methods for measurement of charge decay. Charge decay measures how long it takes for an electric current to dissipate. The quicker it dissipates the higher the anti-static properties of the garment.

Please note the EN 1149-4 Garment Test is under development.

EN 1149-5:

EN 1149-5 specifies the performance and design requirements to avoid static discharge for all electrostatic dissipative protective clothing as part of an entire earthed system, shoes, clothing & floor. The material meets the requirements.

EN ISO 11612 is the standard for protective clothing which protects against heat and flame. Users for these garments include those who work in oil & gas, welding & allied processes, mining, petroleum and many other industries.

There are a host of specific tests conducted as part of EN ISO 11612, including tests for: Flame Spread, Tensile Strength, Tear Resistance, and Heat Resistance.

Flame Spread Test:

A flame is held against the fabric for ten seconds. After it is removed the fabric should not continue to burn. There should be no hole formation, melting or molten debris.

Tensile Strength Test:

The fabric must be able to withstand a minimum force of 300 newtons while being stretched or grabbed.

Tear Resistance Test:

The fabric must be able to withstand a minimum force of 10 newtons before it will tear.

Heat Resistance Test:

The fabric is placed in an oven at 180oC and must not ignite melt or shrink within the first 5 minutes in order to comply with the standard.

Garments must be laundered according to the manufacturer's instructions; incorrect laundering of flame resistant garments can seriously affect their performance and fit.

The flame resistant finish is retained for the normal life cycle of the garment provided that the care instructions are adhered to.

• If dirty stains are difficult to remove, they can be treated before washing with a liquid detergent applied directly to stains and lightly rubbed.
• Never use chlorine bleach or washing detergents containing bleach as these will reduce the flame resistance properties of the fabric.
• Fabric softeners, starches and other laundry additives are not recommended as they can mask the flame resistance performance and may also act as a fuel in case of combustion.

• Always wash contaminated workwear separately
• Always follow the washing temperature on the garment label.
• Always wash and dry garments inside out to minimize surface abrasion and help maintain the surface appearance of the fabric.
• Zips and Velcro fastenings should be closed during washing.
• To ensure a cleaner wash, avoid overloading the machine so the garments can move freely through the wash and rinse cycles.

• Tumble drying is not usually recommended as the temperature used is often too high and can cause garment shrinkage
• It is vital that cotton or cotton mix garments are not over dried as over drying has been determined to be the main cause of excessive garment shrinkage.
• Do not hang in direct sunlight as this can cause fading
