ISO 11611 & ISO 11612 Description

12/28/2019

Managing the risks entailed within the working environment is definitely crucial so as to safeguard workers and also to maintain compliance with all safety and health legislation. Concerning thermal security, an extensive assortment of Personal Protective Equipment (PPE) clothing is present, generally generated from essentially flame and heat resistant substances.

Three planned Security criteria available to producers making PPE clothes protecting employees against heat and fire dangers pay these:

But, further work could be required until a very similar presumption might be supported against the European PPE Legislation (EU) 2016/425.

ISO 14116, nevertheless, is really a specification for immunity to fire spread clothes just. Other foreign standards for clothing avoiding heat and fire are available like the ones produced by ASTM such as the united states, also AS/NZS (such as Australia and New Zealand), however these aren't considered within this report.

SATRA can test and reevaluate clothing to such global heating and fire standards which have compulsory garment evaluations for possessions like limited fire spread, seam durability, and design. Other claims will originate from evaluations to the outside fabric.

All 3 criteria discuss the exact fire immunity test (Restricted Flame Spread)- ISO 15025, that necessitates garment testing before and after pretreatment or cleanup in keeping with the maker's guidelines. Single-use/disposable or leather clothing are exempt from this particular pre-treatment.

"inherently fire retardant fabrics shouldn't shed their restricted flame spread properties supplied a buildup of contamination has been prevented"

Cleaning based on care tag

Inorder to become fully compliant with those standards, manufacturers will need to possess the clothes analyzed after pre-treatment procedures dependent on the care tags and also an individual advice that the manufacturer plans to utilize into the garment. The maintenance tag should define the form of cleanup therapy, the temperature and also the most quantity of cleaning cycles that the garment will experience before its protective operation no further complies with the typical. 

As an instance, a care tag to get a protective garment may specify which the garment needs to really be industrially laundered at 75°C and that the garment ought to be lost after 10 cycles since it might no more be adequately protective. An evaluation house accountable for analyzing that this garment could subsequently take out testing after 10 cycles of washing in line to ISO 11611 in 75°C.


In case the manufacturer hasn't given a maximum amount of cleaning cycles, then those standards define as a default option, five wash cycles. In these situations, but producer needs to refer for the variety of laundry fittings on the care tag and information to utilize booklet, that needs to be given each outfit. In the example of CE marked clothing to the European market it's compulsory this information to use booklet accompanies each garment once sold. 

If this is true that producer determines the garment must perhaps not be properly used, the maintenance tag has to display unfavorable symbols just (i.e. symbols with spans by them), as an instance, usually do not even launder/do perhaps not dry wash.

Inherently fire retardant fabrics must not lose their restricted flame spread properties given a buildup of contamination will be avoided. In the same way, properly treated fire retardant cloths should continue to keep their little fire spread possessions until the garment has escalated via a combo of usage, cleaning and wear. Manufacturers might want to emphasise that in their own usage. Concerning certain claims concerning limited flame spread properties and thermal security possessions, producer should just make claims which may be copied by evaluation data.

As an instance, if your manufacturer's user data booklet says that the garment may be cleaned 25 times, it's saying that the garment will probably be satisfactorily compliant with all the conventional up for the aspect.

This standard is really for protective clothing for use against heat and fire, rather made from elastic substances, would be always to defend the wearer's own body, excepting both hands, feet and head. Normal clothing is actually a cover-all /boiler suit or coat and pants. Other clothing for particular pieces of the human anatomy, e.g. throat curtain, hood, and apron, may be analyzed and licensed along with the lawsuit / cover-all they would be utilised together with.


Clothing must have restricted flame spread properties:

A-1 -- Substance coating evaluations

A-2 -- Substance border

This evaluation is performed on examples of seams in addition to on the fabric. Clothing also needs to meet certain requirements for heating immunity (that includes two performance degrees ) and needs to meet a minumum of one performance degree requirement in some one of those heating transmission evaluations. ISO 11612 comprises five heating transmission evaluations and assigns a letter from this alphabet into each and every one. 

For a garment to Follow ISO 11612 It's necessary it fulfills the minimal requirements of one of those warmth transmission evaluations clarified below:

  • Heat Control connected with fire (also Known as the convective heat evaluation ) is delegated that the code B
  • Heat transmission to glowing heating supply is delegated code correspondence C
  • Heat Control to contact molten aluminium is delegated code correspondence D
  • Heating Control to contact molten iron is delegated code correspondence E
  • Heating Control to contact with a warm item is delegated code correspondence F

The evaluation for heating transmission in the radiant heat source includes four degrees, however others have three degrees. Heat transmission evaluations are worried about measuring just how sexy the inner surface of a garment receives every time a heating source is placed on the outer exterior of the garment.


An optional, whole outfit evaluation procedure can be contained for prediction of burns off, employing a thermal manikin. The manikin testing ought to be completed based on EN ISO 13506 at a heat level within the manikin surface of 8-4 kW/sqm. Once demanded, garments meant to safeguard against the thermal hazards of a electrical arc needs to be assessed based on IEC 61482-2, including special design requirements and performance requirements and evaluation procedures for the appraisal of garments and fabrics against arc.

Physical evaluations

Any claim for molten steel splash or high quantities of heat transmission may signify that the garment drops under Category III of this European PPE Legislation and so necessitates tracking of fabricated production by an European Notified Body. This is sometimes via annual assess testing or auditing of this mill production control technique.

F(x) (where no more operation is announced, the correspondence is omitted)

This standard doesn't cover requirements such as foot, hand, eye or face protection.

The standard is Meant to protect the wearer :

Clothing may also decrease the likelihood of electric shock by shortterm, casual contact with live conductors in voltages as much as approximately 100V dc.

"a garment is analyzed before and following pretreatment using the stitches, hardware and also most of outer substances analyzed"

This standard contains two classes. ISO 11611 comprises two heating transmission evaluations, both which ought to really be completed on material by the evaluation garment, i.e. impact of molten steel droplets, and immunity to the transport of heat. The evaluation results are grouped in line with this operation achieved in to class inch (providing minimum requirements for class 1 have been achieved) or category 2 (providing minimum requirements for class 2 have been achieved).


The debut with this classification enables some flexibility in design and defining welders' clothing. It permits manufacturers to generate lighter weight loss clothing such situations where heat loads are rather low and thicker obligation garments with increased security against perceived hazards for use in areas vulnerable to high rates of spatter or greater heat loads. The typical comes with an informative annex by that welding surgeries are indicated as suited to each type of garment.

Garments certified to EN ISO 11611:2015 will bear labels which have the"welding threat" pictogram and the proper class.

This standard is for security against fire such as substances, cloth assemblies and protective clothing when in short and occasional contact with little fires. If protection against heating threats be required, EN ISO 11612 is important.

A garment is analyzed before and after pre-treatment with the stitches, hardware and also most of outer substances analyzed. The confined flame indicator will likely be the reduced value set earlier or after pretreatment. No anesthetic will emit flaming or debris that is spilled.

Limited flame spread indicator of ISO 11611:

Indicator 3 will be your greater course Without hole higher than 5mm and a later fire of less than five minutes

Indicator 2 permits a gap less than 5mm

Indicator Inch cloth has to be worn within Indicator Two or Three substance and its own' existence and standing suggested

The other evaluation requirements include physical evaluations -- tensile, burst, lie and burst strength together side dimensional equilibrium. Garment tags and data supplied should incorporate the confined flame spread index and also the existence of any indicator inch substance proposed with connection with skin avoided. An promise to EN ISO 14116 will not let using this warmth and fire pictogram without a pictogram can be used.

Garment layout of ISO 11611 & ISO 11612

Both the EN ISO 11611 and also 11612 require that the policy offered by protective suits, so each 1 piece or 2 piece, covers both the upper and lower chest from the neck into the wrists and also into the ankles. Other standards pay for PPE for both hands, face and feet. Additional protective items like aprons, sleeves etc., may be analyzed and certified to those standards, however should just be applied as additional security in addition to a compliant cover-all or 2 piece suit.


To get welders clothing based on EN ISO 11611 and also for EN ISO 11612 clothing made to protect against splashes from molten alloy, special design features are demanded, such as: pay pockets with flaps with the exception of perpendicular pockets below the waist and also supporting the side-seam; ensure no upwards confronting seams are found.


The design and coverage conditions in EN ISO 14116 are less onerous. Perhaps the main requirement is that indicator inch stuff (fundamentally those substances that sustain holing from the fire ignition evaluation ) has to be placed in order they cannot develop in to contact with the bare skin of the wearer along with perhaps a non compliant under-garment. 

In case a garment is composed of indicator inch material subsequently it has to be worn out in addition to indicator 2 or indicator 3 stuff. In the same way, that a multilayer garment could contain an outer shell of indicator inch material, nevertheless the innermost liner which could touch base with the wearer has to maintain index two or three material.

Which usually means that until they are able to be set around the EU market they need to be exposed to your type examination with a notified body and CE marked. Where the garment features protection against particular threats such as quite high degrees of radiant or convective heating, the environmental impacts of the electric arc, or even immunity into large splashes of molten metal they'd be considered category III PPE. 

In the case along with a kind examination additionally they need continuing testing or normal instructions based on Module c 2 or Module D of this Legislation. Like a Notified Body SATRA is able to reevaluate such services and products into the European PPE Legislation and when it comes to category III services and products SATRA can perform the ongoing manufacturing tracking for such clothing.

Notified Statistics are European-based organisations which were made by Member State authorities and advised to the European Commission to the grounds of their capacity to perform the assessments and evaluations needed for CE marking of PPE under Regulation (EU) 2016/425. They have to be independent, unbiased, have a superior amount of professional indemnity insurance and also be susceptible to regular surveillance in fixed intervals. It's likely to spot that which Notified Body has licensed a merchandise as its identify, address and one of a kind number needs to be displayed to the corresponding user details.

A network of agents by the Notified Bodies meet frequently to be sure that the laws and standards have been implemented uniformly across Europe. The classes usually are called'Vertical Categories' (which talk topics associated with a certain commodity type) and also'Horizontal Groups' (that talk more general problems that are related solely to many product categories ). Notified Bodies Take Part in 2 Chief parts of the procedure -- that the'EU typeexamination' or certificate and also for Category III PPE the continuing monitoring of creation under Model C 2 (Annual testing)
