FIRE TESTS ON BUILDING MATERIALS AND STRUCTURES

A. F. Robertson

This report summarizes the discussion and deci-

. sions agreed to at the Eighth Plenary Meeting of ISO/

TC 92, Fire Tests on Building Materials and Structures. Only one standard was proposed for balloting

as a draft international standard for small chimneys.

It V7as referred back to the v/orking group for further

consideration. The reports submitted of progress in

development of standards for smoke control doors and

reaction to fire test m.ethods were well received.

Representatives from ISO/TC 45, Rubber, and ISO/TC

61, Plastics, attended the meeting and stressed the

importance of close liaison between their and other

comiriittees with TC 92. It was agreed that such liaison would be established, however, v/ith caution that

such cooperation v/ould not be interpreted as endorsement of test methods developed by the materials' committees.

Key Words: Chimney; combustibility; fire endurance;

fire tests; flame spread; heat release; ISO/TC~92;

1. INTRODUCTION

The v/riter, Mr. Herbert Eichner, of the Forest Products

Laboratory, and Mr. Jack Bono, of Underwriters Laboratories,

served as delegates and participated in meetings of the Eighth

Plenary Meeting of ISO/TC 92, Fire Tests on Building Materials

and Structures. Mr. S. Hacopian, of the Federal Housing Administration, and Mr. J. P. Carroll, of the Society of Plastics

Industries, participated as observers for the USA. The meetings

were held in Rome, Italy on October 8-11, 19 73 at the Palazo de

Congressi EUR. The draft agenda (DOC 360 EF) , Appendix A, was

used to guide the meetings. This report considers the various

agenda items in the order they were considered at the meeting.

Appendix B lists the delegates attending the meeting.

The delegates were welcomed by high officials of the Italian Ministry of the Interior, the organization under which fire

safety worl: is conducted in Italy. Mrs. Bruce, in the absence

of any officials from ISO Secretari£t Switzerland, opened the

technical session by indicating that. Professor Herpol had been

ill. It had previously been agreed that he would chair the

meeting, but as a result of his illness another chairman would

have to be selected. It was decided that Dr. P. H. Thomas of

the United Kingdom would be an excellent alternate. He agreed

to serve

.

Mr. Sprung of the Yugoslavian delegation asked to make a comment. He reported that t'his was the first meeting of ISO/TC

92 they had attended. They were very concerned with international, standards, especially in connection with marine construction

work. They use ISO and BSS standards and hope to help with, as

well as gain from, the conference.

Agenda Item 3 - Selection of Editing Committee

Messrs Wilson - Dixon, United Kingdom; Lauren, France

Vandevelde, Belgium; de Biase, Italy and Mrs. Bruce of BSI

selected for the work of editing the resolutions developed

the meeting.

Agenda Item 4 - Approval of Draft Agenda

The draft agenda was accepted as proposed. No change of

the items was suggested.

Agenda Item 5 - Progress on Standards, DOC 370

Since few of the delegates had seen this document discussion on it was postponed.

Agenda Item 6 - Report of WG-2, DOC 3 64

This report noted that differences still existed betv/een

DIS 1182 and the Intergovernmental Maritime Consultative Organization (IMCO) test. There was no penalty on specimens which

lost more than fifty percent of their weight and the apparatus

to be used is not sufficiently defined to permit its construction. However, WG-2 proposed to await comment on the balloting

prior to further work on the procedure.

We pressed for the following four points in connection

with this DIS.

1) We wanted detailed drawings referenced in 1182.

2) We wanted a requirement for a minimum fraction of the

spt^cimen to remain after test.

2

3) The method of standardizing the furnace operating condition is awkward and requires use of an optical pyrometer. This is avoided in the IMCO version 4.

The procedure requires a 2 0 minute furnace exposure for

the specimen. It would be preferable to require either 2 0 minute or the time at which all measured temperatures have passed

their peak values.

Many other delegates seemed to be unhappy with the procedure

so we urged that it not be rejected by a negative ballot, but

that comments on its deficiencies be for^varded with an affirmative ballot.

Mr. de Biase had prepared a document by which he proposed

that the ballot be abandoned prior to improvement of the text.

This was not accepted for tv/o reasons:

1) The document had not been circulated prior to the

meeting.

2) There was no practical way to stop a ballot which was

in progress.

Mr. Van Ettern urged that we work toward a rate of heat

release calorimeter. We encouraged this and there seemed to be

general agreement that the non-combustibility test method was

of limited value in many instances. The French delegates showed

preference for their crucible test method. Resolution 92 (see

Appendix C) was adopted to acknowledge the work done by WG-2

.

It was agreed to differ the request that WG-2 take up work

on a rate on heat release test until latter in the meeting.

Item 5 was brought up acain after lunch. This involved the

secretaries report on progress on standard development DOC 369.

She reported as follows:

1) DIS 3008, Doors and Shutters, had received affirmative

ballots from 71% of P members and 85% of ISO members.

Because of this the Secretariat had asked that coram.ents

be considered by WG-3 before publications as a standard.

2) DIS 3009, Glazed Elements, had received only 58% of the

P member ballot and 84% of the ISO membership. The

Secretariat wants this DIS reconsidered.

3) DIS 834 and 1182 are now in process of balloting. The

explanatory technical report will be issued when 8 34 is

released.

3

4) The secretariat has requested that target dates be set

for completion of standards.

There was considerable discussion of this last item, but it

was agreed that there would be no harm in this since it was not

binding. Mr. Mayer, liaison from TC-61 indicated that there was

urgent need for fire standards and we should expedite work.

. I s Agenda Item 8* - Report of WG-4, DOC 361 & 362

Dr. Thomas presented the report for this group he chairs.

He reported that there were no proposals for standards nor for

changes in scope of the committee. The report on their progress

on tests for spread of flame, ignition, smoke, and rate of heat

release and the rational on reaction to fire tests was presented

in DOC 362. We congratulated the group on this document and

urged that at least the introductory rational portion be published promptly. There was considerable discussion on the subject of whether the incomplete descriptions of the test methods

should be included. It appeared that some v/anted the limited

detail presented so that they could conduct tests of their own.

We urged that if they were published, in abreviated form as was

finally agreed, that notes should be provided to caution the

reader that the tests mentioned were still under development and

subject to change.

It was agreed that some minor revisions be made to the introductory material emphasizing the fact that, in general, fire

tests do not measure material properties, but assess system behavior.

I We joined with others in agreeing that prompt publication

was necessary and urged that if this were not available through

ISO it should be published in the technical press elsewhere.

Resolution 89, Appendix C, was developed calling for continued work of the group and publication of the report with abreviated appendixes.

Agenda Item 13 - Report of Liaison With Other Committees

At this point Mr. Eagles, of ISO/TC 45 on rubber, joined

the group and was invited to report on a recent meeting of that

committee. He reported that TC 45 and many of the committees

were concerned with fire test methods. He mentioned a resolution

* At this point a deviation was initiated m the order of considering the various agenda items . They are reported in the

order considered.

4

recently adopted by TC 45 and TC 61 and was asked to furnish a

copy for circulation to merabers . This DOC 373 is enclosed as

Appendix D

.

Mr. Becker was asked to report on work of TC 61. He emphasized the difference in purpose of standards of TC 61 and TC 92.

Those of TC 61 are primarily .for quality control and material

identification while TC 92 was considered for fire hazard evaluation .He summarized work on standard development as follows

:

1) IS 818 relates to ignition resistance of plastics exposed to an incandescent bar at 950 C.

2) DIS 1210 measures flammable resistance of plastic bars.

It is similar to ASTM D-635.

3) R 1326, flammability of plastic films, from 0.015 to

1.5 mm thickness under flarae exposure.

4) R 871, evaluation of flammable gases from plastics.

One gram of plastic is heated to successively higher

temperature until ignition is observed.

5) A new draft standard is under development for foamed

plastics. It is similar to D 1692. The ballot on it

has not been completely successful. .

6) An oxygen index test method is under development.

TC 61 has banned use of descriptive terms to report performance

classification to material tested. They plan to set up a special

working group on fire test methods. No work is currently in progress. They seek liaison with TC 92.

Mr. Laurin reported that SC 19 of TC 38 on Textiles is also

concerned V7ith the need for liaison with TC 92. A letter has

been directed to ISO from TC 38 recommending that TC 92 should

develop tests for fabric wall and floor covering materials to

be used in buildings.

Mr. Malhotra recommended development of a document to discuss the difference between fire hazard tests and material identification fire tests. This started a general discussion on the

need for small scale tests and the danger of their possible misuse. The need for liaison with the other committees was generally recognized but it was considered that such liaison might

imply endorsement of the standards developed by the materials

committees

.

5 i

Mr. Eagles emphasized the need for liaison he mentioned

that V7G-14, TC 45 has developed a horizontal burning test for

foamed rubber. They are working on a smoke test method.

At this point we reported on recent developments at ASTM

with regard to its proposed new fire test policy.

Resolution 90 (Appendix C) was passed calling for liaison

with' TC 45 and 61 but stressing need to avoid implication of

endorcing their tests. Resolution 91 was also accepted. This

welcomes the offer of help from TC 61 for work on a smoke test

method.

At our suggestion it was agreed that Dr. Thomas should

serve as liaison to these committees and report back when appro

priate to TC 92.

Resolution 9 3 was then passed thanking WG-4 and urging

continued efforts to develop test methods.

At this point discussion again developed on the need for a

heat release rate calorimeter. We supported the need for devel

opment of a test for this property, but emphasized that whether

it is done in WG-2 or WG-4 is of no concern to us. It should

be expedited. It was at this point that Resolution 92 was developed calling for cooperation between WG-2 and 4 and development of a heat release rate calorimeter.

Agenda Item 7 - Report of WG-3, DOC 36 3

Mr. Malhotra reported on the work of this Group he chairs.

Apparently the French and some others, during balloting on DIS

3008 and 3009, had complained about the use of a canope in connection with these door and glazed element test methods. He

spent some time discussing t'le desireability of using the canop

at least until experience is gained on its value. He reported

that no real progress had developed on an impact test. It was

reported that several countries including UK considered that

such a test should be developed. He reported on the decision

to use the term "smoke control" rather than "smoke stop" door.

He also mentioned the three different conditions under which

such doors could be useful and for which tests were being considered:

1) Cold smoke with unifomn pressure over door surface.

2) VZarm smoke with neutral pressure condition between top

and bottom of door.

3) A door to serve fire endurance and smoke control pur-

poses

.

It was noted that progress had been made for condition 1 and 3

which were thought to provide means for the easier solution.

In discussing this report, Mr. Wilson - Dixon of UK made

the comment that we are sure there is little value for condition

2. , I A vote was taken on interest in each of the conditions mentioned. The order of preference was 1, 3, 2. Both Professor

Pettersson and Mr. Becker commented on the fine quality of the

report. The Yugoslavian delegation reported that they had information on gas flow through window assemblies and said they

would make this available.

We suggested caution on the assumption that smoke control

doors would really limit smoke movement in a building and stressed the need for ventilation design to manage smoke movement during a building fire. We also emphasized the probable need to

test doors over a range of pressures broader than would be implied by requiring that a neutral pressure zone be between the

top and bottom of the door.

Resolution 95 was adopted at this point to encourage WG-3

to continue the work started.

Mr. Malhotra asked for infoirmation on the behavior of doors

in control of smoke during actual fires. The delegates were encouraged to forward any information they became aware of on this

subject.

^

Agenda Item 9 - Report of WG-7, DOC 365

Mr. Minne presented a summary of the report prepared by

this committee on co-relation and coordination of fire tests.

It was reported that contact had been made with TC 14 0 in

connection with fire tests of floor covering materials. They

also propose to study the test methods being prepared by TC 45

and TC 61. Professor Minne summarized the report:

1) Limits of performance criteria should not be included

in standards.

2) The scope of WG-7 be enlarged to include other building

furnishing and occupancy items than just construction

materials

.

3) That WG-7 planned to recommend that ISO conditioning

Standards be maintained for both 50 and 65 percent re-

lative humidity but if one had to be dropped it would

be that for 50% RH.

4) That WG-7 planned to circulate all ISO member countries

a questionnaire on standards adoption procedures.

5) That they should insist that other ISO committees working on fire standards should so notify TC 98.

6) To permit continued operation of WG-7.

We complained about item 3 above and pointed out that the

proposal could result in encouraging adoption of a conditioning

atmosphere v/hich would, if applied to fire tests, result in a

higher m>oisture content of the specim.en and thus less flammable

conditions. It was observed that the fire test methods at present called for 40-65 percent RH. We pointed out that this resulted from both the difficulty in achieving a closely specified

moisture condition and reluctance of all laboratories to agree

on a uniform condition. We pointed out that if only one condition was specified there would be a danger that conditioning

equipment would be installed in laboratories which would not be

most useful for conditioning fire test specimens.

Considerable discussion followed on this point. Resolution

96 was then prepared and among other items, authorized WG-7 to

review the problem of conditioning atmosphere.

Agenda Item 10 - Report of WG-9, DOCS 366 & 367

Dr. Odeen, chairman of the group presenting this report,

summarized the work and indicated that it had been decided in

the early stages that the standard for small chimneys and flues

should be based on a Swedish standard. DOC 367 is the result

of the work done. It specifj-cally excludes uninsulated tubes

and requires one source of fuel oil to simplify the test procedure. They also decided not to consider the possibility of ignition of wood framing around the flue.

Col. Cabret complained that consideration had not been

given to the French test. Mr. Bono presented our views and

after apologizing for our lack of participation in the work, he

made the following points:

1) In USA appliances of medium and high heat classifications involve stack gas temperatures above the 500°C

specified in DOC 367 so the test would not be useful

for evaluating their performance under phase 2.

8

2) The soot burn out or test phase starts from a low temperature whereas v/e would normally start it after extended normal operation. Thus the proposed test is

less severe than those we use since lower exterior surface temperatures v7ould be expected.

3) There is no requirement that simulated insulation or

framing exclosures are not provided around the flue at

locations such as floor or roof openings. These usually

tend to increase exterior surface temperatures and may

be critical locations.

There were further complaints and suggestings from UK and

Germany. Items included:

1) Why do we need so complex a test for an item used so

long.

2) Why do we have to limit the flue size - many chimneys ' require larger areas

.

3) The definition of combustion conditions is not complete.

Smokeless combustion should be specified.

4) It V7as suggested that the tightness test should be

conducted on a hotter chimney than would be the case

an hour after a test at 200°C.

5) The stack height should be allov/ed to vary.

6) This type of test has been in use of 35 years. Is it

useful now if USA appliances differ so much in outlet

temperature?

Dr. Odeen was not completely successful in explaining why

they had made the decisions v.hich were being criticized.

The chairman suggested a ballot to determine the extent of

agreement with the test:

Negative 3 USA, France & Hungary

Positive 8

Abstain 3 UK, Canada & one other

It was decided to refer the document back to the working group.

They were authorized after review and revision to either submit

it for letter ballot or for consideration at the next plenary

meeting of the Committee. Resolution 9 7 was then adopted authorizing this further work.

9

Agenda Item 11 - Report of WG-10, DOC 368

Mr. Bellisson, chairman of this working group on instrumentation, presented a summary of the work to date. A very

broad range of measurement problems had been proposed for consideration. These included:

. 1) Temperatures - in all types of tests

2) Radiation - in all types of tests

3) Photometers

'4) Opacity of smoke

5) Heat Flux

6) Pressure in furnaces

7) Leakage of flames and gases through specimens

8) Gas composition in furnaces

9) Forces and pressures

10) Displacements

We encouraged preparation and publication of documents on

specific instruments. Mr. Malhotra suggested limiting the work

to a few topics at a time.

It was agreed to ask that emphasis be placed on measurement of temperature and radiation for the time being. Resolution 98 was prepared at this time. Mr. Bellisson indicated that

he hoped to have documents ready for consideration at the next

meeting.

Agenda Item 12 - Report of WG-11, DOC 369

The report of this working group on the fire endurance test

was presented by Professor Kordina, the chairman. He noted that

they were authorized to consider revisions to R 834 as well as

develop new standards.

He reported work on heat transfer within furnaces as well

as studies of integrity, failure criteria (cotton wool test)

.

Professor Pettersson has agreed to develop a document relating

to fire tests of external structural elements (usually columns)

.

He himself is preparing a draft test for suspended ceilings. He

noted that tests of beam-column assemblies require elaborate

fire test equipment and noted that both UK and Germany were considering such facilities.

Col. Cabret asks that emphasis be placed on 834 and suspended ceilings. Mr. Malhotra also encouraged that emphasis be

placed on work on suspended ceilings and we supported the suggestion .

10

Professor Kordina agreed with this, but indicated that

there are many systems and standardization will be difficult.

A diversion took place in discussion of UATC (uniform international data acceptance) . This as apparently similar to the

laboratory accreditation work in USA. Discussion relative to it

was 'ruled out of order by the Chairman. Resolution 100 was then

adopted

.

Agenda Item 13 - Consideration of New Work

Mr. Laurin reported that WG-6 has prepared an additional

list of 50 terms which they proposed to consider with regard to

possible future inclusion in vocabulary of fire terms. This

list has been circulated to members of WG-6. The group proposes

to work on these without a chairman.

We asked to be kept informed on any work undertaken. This

was agreed to.

Mr. Malhotra commented that most of the terms were not

limited to fire matters and he considered that most would be

readily found in any good technical dictionary. In spite of

these comments WG-6 was apparently authorized to proceed with

work on this new list of terms.

We reminded the committee that it had previously been promised that equivalent terms would be identified in other languages. This was agreed but preference was given to delay of work

on these until comments on the merit of the first list had been

secured. It was agreed to circulate this list to TC 45 & 61 and

other comiaittees concerned with fire problems.

We called attention to the increasing concern in USA with

more complete evaluation of the real full scale fire hazard

situation. We described the new ASTM fire test policy and the

distinction being drawn between fire hazard tests and those for

material characterizations. Colonel Cabret reported concern

for tests for roofs, facades, etc.

Agenda Item 14 - Other Business

Mr. Malhatra proposed to expedite work at the plenary

meetings by circulation of proposals for DIS to member bodies

for voting prior to the meeting. Comments could then be considered by the working groups and chenges made prior to the meeting. It was generally agreed that the objective was a desire11

able one but the means for achieving it was quite uncertain.

Agenda Item 15 - Approval of Resolutions

The typed versions of resolutions 89 to 9 8 were reviev/ed

and necessary corrections incorporated. Three additional resolutions were adopted: 99, on target dates for completion of

draft standards, 100, with regard to work of WG-11, and 101 with

regard to WG-6 and its work and terminology. These are all included in Appendix C.

Agenda Item 16 - Next Plenary Meeting

It was agreed that the next meeting of ISO/TC 92 would be

held in Britain, probably during the week of October 6-12, 1975.

Agenda Item 17 - Brief Minutes of Meeting DOC 375

This document is included as Appendix E.

Agenda Item 18 - Closure of the Meeting

The meeting was concluded at about 1:30 p.m.. on Thursday,

Report but asked the CHainnan, in consultation v;ith members of VJG4, to edit the document to concentrate the

Appendices into a reduced and balanced form, to give a description of the apparatus and general guidance on procedure without the complete detail of the existing draft,

90 ISO/TC 92 has noted the Resolutions passed by ISO/TC 45

arid ISO/TC 61 regarding liaison betv7c en themselves and

other Technical Committees on Laboratory scale fire tests,

TC 92, because of its role in developing tests relating

to real fire hazards, has reservations about participant^jis^

fully in the worl: of a liaison committee in view of the

stated different objectiv s of their tests. It however

V7elcomes the opportunity to co-operate V7ith the liaison

Working Group 2 wcs thanked for Its woric on the non-combustibility test (DIS 1182) and v;as ask.ed to examine any

further technical coirments V7hich are submitted at the Member Body voting stage. The Plenary Session askes VJG 2

and VJG 4 to re-allocate their resources in co-operation

to hasten the development of a rate of heat release test.

Working Group 4 was thanked for i--&e-JefeitisM«~eenirribtt^r^

to the development of tests for reaction to fire, and is

urged, in view of the interest in this subject expressed

by various national and international organizations to

hasten as much as possible the finalising of its proposals

for the various tests,

ISO/TC 92 re-states its proposals to invite other ISO

Technical Committees to collaborate vTith it, with_ a view

to studying the problems presented by safety from fire in

their various fields and c ntends that close collaboration in the preparation of fire tests is essential if these

problems are to be resolved.

approve the following resolution:

RESOLUTION : That the Secretariat of TC 45 writes to the ISO

Central Secretariat telling them of the great importance placed on the fullest use being made of

consultations between Technical Committees interested m small scale laboratory fire tests and that

to this end the Central Secretariat takes the necessary steps to ensure that the liaison committee

^ is accorded an official status appropriate to the

Delegates froa sixteen member countries attended the Eighth

Plenary Meeting of ISO/TC 92 held fron 8-12 October 197 3 at the

Palazzo dei Congressi, Rome, In addition liaison representatives

were present froni ISO/XC 45 Rubber, ISO/TC 59 Building Construction

and ISO/TC 61 Plastics, A welcome was extended to the delegates

by ViT, Fontana on behalf of UNI, Kr. Righetti on behalf of the

Ministry of the Interior and Mr. Renato, Direzione Generale della

Protezione Civile e Servizi Antincendi. The Committee received

reports from its eight v/orking; groups on progress made on the

development of fire tests for building materials and structures,

A number of Draft International Standards are at present with

Meiiiljci' Bodies of ISO foi' vote. The fire tests for door and shutter

assemblies and for glazed elements have received the necessary

percentage of affirmative votes but require further consideration

of editional comments,

A draft proposal for fire tests for small chimneys was considered but the technical comments made necessitated its reference

back to the V7orking Group for re-drafting.

The results of the work on a series of tests for reaction

to fire v/ere presented in the form a Technical Report, This work

is considered of major importance and the V/orking Group was urged

to hasten the finalization of draft proposals for tests on surface

spread of flame, ignitability , smoke production and rate of heat

release.

Progress on work on measuring instruments and calibration of

apparatus for fire tests was reported from another V/orking Group.

Progress has also been made on fire resistance tests for other

structural elements such as suspended ceilings and external

columns. Studies are being carried out on roofs and bearing

assemblies

ABSTRACT (A 200-word or less factual summary of most significant information. If document includes a significant

jibliography or literature survey, mention it here.)

j This report summarizes the discussion and decisions agreed to at the

'ghth Plenary Meeting of ISO/TC 92, Fire Tests on Building Materials and

iructures. Only one standard was proposed for balloting as a draft inrnational standard for small chimneys. It was referred back to the

rking group for further consideration. The reports submitted of proess in development of standards for smoke control doors, and reaction

I fire test methods were well received. Representatives from ISO/TC 45,

bber, and ISO/TC 51, Plastics, attended the meeting and stressed the

portance of close liaison between their and other committees with TC 92

was agreed that such liaison would be established, however, with

ution that such cooperation would not be interpreted as endorsement of

St methods developed by the materials' committees.
