)

50-328 Ih the enclosure to my letter to R. S. Boyd dated January 24, 1977, commitments were made to use a mastic coating similar to Flamemastic 71-A on exposed cables in the area of divisional interactions at Sequoyah Nuclear Plant. This material is also being used as part of the plant's cable tray penetration design.

The Tennessee Air Pollution Control Regulations and the Hamilton County Air Pollution Control Regulations prohibit the use of Flamemastic 71-A since it centains asbestos fibers in a concentration exceeding prescribed limits. We therefore request approval of asbestos-free Flamemastic 77 as a substitute for 71-A for the identified applications. The six enclosures listed below provide data and references justifying the adequacy of the substitution.

FLAMEMASTIC 77 SPRAYABLE FIRE RETARDAhT COAllNG FOR ELECTRICAL POWER AND CONTROL CABLES from THE FLAMEMASTER CORPORATION 11120 SHERMAN WAY SUN VALLEY, CALIFORNIA 91352 I

INTRODUCTION 1.1 The Flameraster Corporation requested approval of their Flacemastic,77 sprayable fire retardant coating for use on electrical power and control cables.

f This coating will prevent fla=e spread in grouped conductors when exposed to a moderate fire source as might occur from arcs or sparks falling or occurring in a cable tray, or from fire exposure of combustible trash or foreign material around the cables in grouped or trayed arrangement.

1.2 Flacemaster 77 sprayable coating is compounded of water-based thermoplastic resin flame retardant chemicals and inorganic incombustible fibres.

It contains l

no asbestos.

It is thixotropic and the nonvolatiles average 697. by weight.

It has an off-white appearance before and after curing. Service temperature range is from -30*F (-34*C) to 180*F (82*C) af ter application and curing in accordance with the manufacturer's instructions.

a 1.3 Precautions should be taken to insure that a'ny storage, transportation or application of this caterial is done in te=peratures above freezing because J

of the water content. Recoc: mended storage limits are from 40*F (4*C) to 90*F (32*C).

~

II DESCRIPTION 2.1 Surfaces to be coated with Fla=astic 77 must be clean and free from oil, dust and grease.

Flamastic 77 must be thoroughly mixed to a uniform con-sistency. Either air atomized or airless spray equipment produces satisfactory results when applied as reco=cended by the canufacturer.

with clean water.

Cleanup is accceplished 2.2 Flamastic 77 must be preconditioned to a minimum 70*F (21*C) for 24 to 72 hr prior to spraying to -chieve optimum results. Application of Flame =astic 77 is by applying a thin (fog) coat and allowing 10 min. drying time before building s

Page 3 t ime, this high potential test was repeated to insure that no change or damage had occurred to the cable insulation prior to or during the coating application.

(This test is also repeated af ter the fire test described below, as an added means of determining any insulation breakdown.)

4.4 Three 3 ft (0.9 m) long coated cables were individually heated electrically with 150% of rated current (430 A) until the conductor te=perature stabilized at 159'F (71*C). A flame from a Meeker gas burner, adjusted to give an overa 1 natural gas flame height of 5 in. (127 cm) with a 3 in. (76 cm) inner cone was applied to the horizontally positioned cable for 2 min. with the tip of the inner cone touching the bottom of the coated cable. At the end of a 2 min.

flame exposure, there was simultaneous burner flace cutoff and electrical shut-down. All flames extinguished within 15 sec. After cooling, the charred and scorched area exposed to the burner flame was measured and found to be less than 3 in. (76 mm) in length. This s4tisfies approval requirements that burning shall not continue longer than 1 min. after flame cutoff and that the burned (exposed) area shall not exceed 9 in. (228 cm) in length, i

4.5 Resulcs on the second and third cables exposed to the test described in Paragraph 4.4 were similar. The three cables were then given a repeat of the high potential test described in Paragraph 4.3 and current leakage was approximately 0.2 mA.

This satisfies the approval requirement that leakage current shall not exceed 5.0 mA when measured between a conductor and the outer jacket during this high potential test.

4.6 A 3 ft (0.9 m) length of cable coated with Flamemastic 77 was sub-jected to a salt water test consisting of 8 he sub=erged, alternating with 16 hr of drying in a 24 hr span over a 30 day period in a 1% salt solution with a water temperature of 150*F (66*C). At the end of this period the sample was allowed to dry for 36 hr.

Examination showed that there was no disintegration or deterioration of the coating from this exposure. The cable sample was then subjected. co the fire test described in Paragraph 4.4 and a high potential test (see Paragraph 4.3); and the results of these tests were satisfactory.

4.7 Two 3 ft (0.9 m) lengths of cable covered with Flamemastic 77 vere

(

subjected to alternating temperatures of 160*F (71*C) and -40*F (-40*C) for l

24 hr periods over a 2 week duration. At the end of this accelerated aging test the sample cables were then subjected to the fire test described in Paragraph 4.4 and the high potential test (see Paragraph 4.3).

The results of these tests were satisfactery.

4.8 A coated cable section was subjected to an ampacity test prior to l

vhich a No. 28 gage chromel-alumel thermocouple was imbedded in the bare copper I

conductor. The cable was then subjected to its rated current carry,ing capacity of 285 A (according the National Electric Code) until the temperature indicated by the thermocouple had stabili:ed, in approximately 1 hr 15 min. at 100*F l

(38'C) in an ambient temperature of 72*F (22*C).

This is well below the 194*F (90*C) maximum temperature rating of the cable insulation. Therefore no electrical derating is necessary when a cable is coated with Flame =astic 77 according to l

the manufacturer's recommendations.

~wka - um MODIFIED IEEE - 383 FIRE TEST

Purpose:

To determine the effectiveness of Flamemastic 77 as a fire protective coating applied to grouped cables.

Test Method:

The pre-assembled cable tray was placed vertically in a fire chamber l

(3.0' W x 2.2L x 3.0 H) and a 20 minute fire test was conducted using IEEE-383 type burner. A 15000F temperature was maintained throughout the test. The BTU input was 80000/Hr. for each test.

The results of the test were determined by the following observations:

1.

The condition of the cable and or coating after the 20 minute test period.

2.

Time to self-extinguish after burner was turned off.

Results:

(

Modification I - Uncoated:

IEEE-383 cables burned completely where as cables coated with Flamemastic 77 did not propagate flame. The coating remained intact and there was no after-burn.

IEEE-383 cables coated with

a. competitive coating were also completely destroyed in this test. (See AttachedTable)

Modification II:

In this case not only non IEEE-383 uncoated cables burned completely, but the cable coated with the competitors coatings also burned completely, while cables coated with Flamemastic 77 did not' propa' gate flame and the coating material remained intact. There was no af ter-burn.

(See Attached Table)

C0?tCLUSI0 tis:

Tests proved that clamemastic 77 offers unsurpassed fire protection for grouped electrical cables. The performance was superior to any competitive material tested. Phen the tests of Flamemastic 77 were compared with sim-ilar tests conducted with Flacemastic 71 A, it was concluded that Flamt stic 77 was equal or surarior in its fire protective performance.

(

j Combustion tests indicate that Flamemastic 77 does not support combustion and burns only with difficulty as long as it is in contact with a very hot exter-nal flame. When the external flame is removed, the material is self-extin-guishing. The pyrolysis-combustion process evolves s dense grayish white smoke, and leaves a dense char covered with small pearly glass beads on the surface.

4 Analyses were made of the combustion gases, smoke deposit on glass, and of the char / ash.

A discussion of the analytical methods along with results of the analyses are attach ed.

ARLI Lab Log 67083 Scope The following studies are of a general survey nature to develop the maximum useful information concerning pyrolysis-cornbustion character-istics of Flamemastic-77 in a short time.

Test Methods Approximately 3 gms of Flamemastic-77 were put into a small nickel boat suspended with a wire from a post on the base of a bell jar chamber.

The boat and contents were heated with an air-gas burner until the boat was red hot.

(

During heating the glass bell jar was held just above the boat to entrap at least some of the evolved gases and smoke particles. No flame was observed above the mastic. While the boat was red hot, the burner flame was played over the surface of the mastic. This produced some flame above the mastic, and charring of the surface. When the burner flame was removed, the mastic flames extinguished immediately. At this time (boat still red hot) the glass bell was lowered to the base to entrap any further gases evolved.

The trapped gases were analyzed by mass spectrometry. To obtain an analysis of the minor components, the balance of the trapped gas was pumped through a liquid nitrogen cold trap which removes the nonconden-sible gases such as nitrogen, oxygen, and argon, leaving the condensibles for analysis.

The smoke deposit left on the glass walls of the bell jar, and a sam-ple of the char ash were analyzed by emission spectrometry.

Results k

Burning Observatim.s - The specimen of Flamemastic-77 did not support

s-Flamemaster Corporation Page 2 of ARLI Lab Log 67083 flame propagation. Playing an air-gas burner flame over the surface of the hot mastic produced a dense grayish white smoke and only a small flame which self extinguished immediately upon removal of the burner flam e.

The material subjected to the burner flame left a dense residual char, as described above, indicating incomplete combustion.

Analysis of Gaseous Combustion Products -

Mass spectrometric analy-sis of the trapped atmosphere gave the following:

Vol-%

N 79*9 2

O 18.1 2

A

1. O CO

1. O 2

The above data indicates that only slight combustion of the organic matter in the sample took place after the removal of the burner as a little CO and 2

a large excess of air are evident. It is conceded that traces of carbon mon-oxide also may be present, but it is not detectable by mass spectrometry when a large amount of nitrogen is present.

Analysis of Condensible Products of Trapped Gas - Mass spectrometer analysis of the liquid nitrogen trapped atmospheric gases gave the following:

Acetone 29.

Benzene 88.

Toluene 15.

• Tentative identification - the mass spectra are consistent for the presence of these compounds, but further work would be needed for unequivocal identification.
