Portwest WX3 Modaflame Rain+ FR Shell Trousers - Black

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.

EN343 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 pictogram to the left indicates that protection against rain is offered.

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.

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

For chemical protective clothing offering limited protective performance against liquid chemicals (Type 6 and Type PB [6] equipment). This standard specifies the minimum requirements for limited use and re-useable limited performance chemical protective clothing.

Limited performance chemical protective clothing is intended for use in cases of a potential exposure to a light spray, liquid aerosols or low pressure, low volume splashes, against  which a complete liquid permeation barrier (at a molecular level) is not required.

Type 6 Requirements

Type 6 Chemical Protective suits must cover and protect at least the trunk and the limbs.

Example: One piece coveralls or two piece suits (with or without hood), boot-socks, or boot covers.

Type PB [6] Requirements

Type PB [6] Partial body protection covers and protects only specific parts of the body.

Example: coats, aprons, sleeves.

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 13034 specifies the performance requirements for disposable and re-usable limited performance chemical protective clothing (Type 6 and (Type PB [6]) garments. Limited performance chemical protective clothing (disposable and re-usable) is intended for use in cases of a potential exposure to a light spray, liquid aerosols, low volume splashes and in circumstances where a complete barrier to chemical exposure is not required.

The standard covers both chemical protective suits (Type 6) and partial body protection (Type PB [6])

Chemical Protective Suits (Type 6) cover and protect at least the trunk and the limbs, e.g. one piece coveralls or two piece suits with or without hood, boot-socks, or boot covers.

Partial Body Protection of similar limited performance Type PB [6] covers and protects only specific parts of the body, e.g. coats, aprons, sleeves, etc.

In order to ensure that a chemical protective suit meets Type 6 protection, it is tested using a mist or fine spray of water. The water is dosed with a mild detergent to produce a specified surface tension and injected with a dye to aid the assessment of leakage. The test subject wears an absorbent suit underneath the one to be tested, which absorbs any leaks and is stained by the dye. Success or failure is determined by measuring the total area of any stains on three suits and comparing this with the requirement. Leaks will typically occur at closures and interface areas, but the liquid can also seep through the material itself.

Type PB [6] testing is conducted in a similar way to the Type 6 suit test but only on partial body garments such as sleeves, aprons, coats, etc.

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.
