Protective clothing - Assessment of resistance of materials to molten metal splash (ISO 9185:2007)

ISO 9185:2007 specifies a method for assessing the heat penetration resistance of materials intended for use in clothing to protect against large splashes of molten metal. It provides specific procedures for assessing the effects of splashes of molten aluminium, molten cryolite, molten copper, molten iron and molten mild steel. The principle of the test method is applicable to a wider range of hot molten materials than those for which specific procedures are set out, provided that appropriate measures are applied to protect the test operator.

Schutzkleidung - Beurteilung des Materialwiderstandes gegen flüssige Metallspritzer (ISO 9185:2007)

Diese Internationale Norm legt ein Verfahren zur Beurteilung des Wärmedurchgangswiderstandes von Materialien, die für Schutzkleidung gegen große Spritzer flüssigen Metalls verwendet werden, fest. Es werden Verfahren festgelegt, zur Bewertung des Effekts von Spritzern von geschmolzenem Aluminium, geschmolzenem Kryolith, geschmolzenem Kupfer, geschmolzenem Eisen und geschmolzenem unlegiertem Stahl (Baustahl).
Das Prinzip dieses Prüfverfahrens ist darüber hinaus anwendbar auf einen weiteren Bereich von erhitzten geschmolzenen Materialien als die, für die spezifische Prüfverfahren angegeben sind, vorausgesetzt, angemessene Sicherheitsmaßnahmen zum Schutz des Prüfpersonals werden angewendet. Es ist wichtig zu erwähnen, dass ein hoher Widerstand des Materials gegenüber Spritzern von reinem geschmolzenen Metall nicht gleichzeitig eine gute Schutzleistung gegen Schlacke garantieren muss, die in einem Herstellungsprozess auftreten kann.

Vêtements de protection - Évaluation de la résistance des matériaux aux projections de métal fondu (ISO 9185:2007)

L'ISO 9185:2007 spécifie une méthode d'évaluation de la résistance au passage de la chaleur caractérisant les matériaux destinés à être utilisés dans les vêtements pour assurer une protection contre les projections importantes de métal fondu. Elle fournit des modes opératoires spécifiques pour évaluer les effets des projections de métaux fondus tels que l'aluminium, la cryolite, le cuivre, la fonte et l'acier doux. Le principe de la méthode d'essai est applicable à une plus large gamme de matériaux fondus que ceux pour lesquels des modes opératoires spécifiques ont été fixés, sous réserve que soient mises en oeuvre des mesures appropriées pour protéger l'opérateur d'essai.

Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies

(ISO member bodies). The work of preparing International Standards is normally carried out through ISO

technical committees. Each member body interested in a subject for which a technical committee has been

established has the right to be represented on that committee. International organizations, governmental and

non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the

International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.

The main task of technical committees is to prepare International Standards. Draft International Standards

adopted by the technical committees are circulated to the member bodies for voting. Publication as an

International Standard requires approval by at least 75 % of the member bodies casting a vote.

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent

rights. ISO shall not be held responsible for identifying any or all such patent rights.

ISO 9185 was prepared by the European Committee for Standardization (CEN) Technical Committee

CEN/TC 162, Protective clothing including hand and arm protection and lifejackets, in collaboration with

Technical Committee ISO/TC 94, Personal safety — Protective clothing and equipment, Subcommittee SC 13,

Protective clothing, in accordance with the Agreement on technical cooperation between ISO and CEN

(Vienna Agreement).

This second edition cancels and replaces the first edition (ISO 9185:1990), which has been technically revised.

This second edition includes the following significant technical changes compared to the first edition:

a) new PVC sensor film included;
b) Cryolite included as test metal.

Introduction

ISO 9185:1990 and EN 373:1995 have been used up until now with reasonable success as the principle test

methods for materials used in the manufacture of clothing to protect against large splashes of molten metals.

EN and ISO specifications cite these test methods and set levels of performance in terms of the mass of iron

or aluminium that can be splashed onto test materials without producing damage to the heat sensor film.

The revision of the test methods contained within this International Standard incorporates changes based on

experience that are intended to improve reproducibility and to respond to incident data from the aluminium

smelter industry. A test procedure is therefore introduced to determine the protection provided by materials

when splashed with molten cryolite. This revision also harmonises into one test procedure the previously

slightly different procedures in ISO 9185 and EN 373 for testing with molten aluminium.

A new supply of PVC sensor film has been established together with a new world-wide distributor – see note

in the text. One single specification for PVC film replaces the previously different ones in ISO 9185 and

EN 373.

The test method in this International Standard is distinct from that in ISO 9150, which assesses the protective

performance of materials intended to be manufactured into protective clothing for welding activities.

INTERNATIONAL STANDARD ISO 9185:2007(E)
Protective clothing — Assessment of resistance of materials to
molten metal splash
1 Scope

This International Standard specifies a method for assessing the heat penetration resistance of materials

intended for use in clothing to protect against large splashes of molten metal. It provides specific procedures

for assessing the effects of splashes of molten aluminium, molten cryolite, molten copper, molten iron and

molten mild steel.

The principle of the test method is applicable to a wider range of hot molten materials than those for which

specific procedures are set out, provided that appropriate measures are applied to protect the test operator. It

is important to note that good resistance of a material to a pure molten metal does not guarantee a good

performance against any slag that can be present in a manufacturing process.
2 Normative references

The following referenced documents are indispensable for the application of this document. For dated

references, only the edition cited applies. For undated references, the latest edition of the referenced

document (including any amendments) applies.

ISO 683-1:1987, Heat-treatable steels, alloy steels and free-cutting steels — Part 1: Direct-hardening

unalloyed and low-alloyed wrought steel in form of different black products
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
damage

〈PVC sensor film〉 any smoothing or modification to the embossing or pinholing of the PVC sensor film,

extending in total for at least 5 mm across its width

NOTE Where the visual change in appearance is in discrete spots, damage occurs when the summation of the width

of each spot exceeds 5 mm across any horizontal section. For cryolite, experience indicates that damage can be defined

as less than 5 mm in width, but greater than 10 mm in length.
3.2
molten metal splash index

figure equal to the minimum mass of molten metal poured which just causes damage to the PVC sensor film

4 Principle

Materials are tested by pouring quantities of molten metal onto the test specimen supported at an angle to the

horizontal on a pin frame. Damage is assessed by placing an embossed thermoplastic PVC sensor film

directly behind, and in contact with, the test specimen and noting changes to the film after pouring. Any

adherence of the metal to the test specimen surface is also noted. Depending on the result, the test is

repeated, using a greater or smaller mass of metal, until the minimum quantity to cause damage to the film is

observed.

5 Apparatus and materials

5.1 Metals and cryolite complying with the specifications set out in Annex A. Other metals or substrates

appropriate to the end use.

NOTE It is advisable that coarse filings or small pieces cut from solid bar or sheet be used, because fine filings have

proved difficult to melt. A range of pouring temperatures used in industry for different metals and for cryolite is given in

Annex A.
1) 2

5.2 PVC sensor film , comprising an embossed PVC sheet, of mass per unit area (300 ± 30) g/m , which

when tested as described in Annex B shows no smoothing or modification of the embossing of the central

area at a block temperature of (166 ± 2) °C but which shows smoothing or modification of the central area at a

block temperature of (183 ± 2) °C. The procedure set out in Annex B shall be undertaken no more than

30 days before any one day of testing in accordance with this International Standard.

NOTE The reason for this continuous calibration of the PVC sensor film is that it is likely to change over time

because of plasticizer loss. It is advisable that the PVC sensor film be stored in a cool and dark location so as to minimize

such changes. Because of the economics and consistency of production, one batch of at least 1500 m is produced and

then used by test laboratories over a period of several years.

5.3 Crucible, whose approximate external dimensions are a height of 97 mm, a top diameter of 80 mm, a

bottom diameter of 56 mm and a capacity (brim full) of 190 ml (see Figure 1).

NOTE For most molten metals, including iron, a graphite impregnated material (if an induction furnace is used) has

been found suitable for the crucible.
