Test Methods portion, Section 5of this speciﬁcation: This
standard does not purport to address all of the safety concerns,
if any, associated with its use. It is the responsibility of the user
of this standard to establish appropriate safety, health, and
environmental practices and determine the applicability of

tested in accordance with 5.8. At rupture of the panel the

veneer plaster shall be securely bonded to the face paper.

5. Test Methods

5.1 Materials—Gypsum Base for Veneer Plaster, see Speci-

ﬁcation C1396/C1396M.

5.2 Sampling—Sample not less than 1 % of the packages,

but not less than 5 packages. Select packages to be sampled at

random. Take samples both from the outer portion and the

center of each package. Thoroughly mix the materials so

obtained to provide a composite sample of not less than 15 lb

(6.8 kg). Place this composite sample immediately in a clean,

dry, airtight container for delivery to the laboratory.

5.3 Test Unit Preparation—From the sample, prepare panels

of veneer plaster system and cut four 2 ft (600 mm) square, and

three 12 by 16 in. (300 by 400 mm) specimens.

5.4 Conditioning—Condition specimens to constant weight

at a temperature of 85 615°F (29.5 68.5°C) and relative

humidity of 50 62 % (see Note 2). Test specimens individu-

ally after constant weight is reached.

NOTE 2—Laboratory test results indicate that conditioning temperatures

may range from 70 to 100°F (21 to 38°C) without signiﬁcantly affecting

the results. However, relative humidity is critical. Therefore, specimens

shall be tested within 10 min upon removal from the conditioning

chamber.

5.5 Number of Tests—Run each test in triplicate.

5.6 Bond Strength:

5.6.1 Signiﬁcance and Use—The bond strength test is de-

signed to evaluate the bond of veneer plaster to veneer plaster

base and between the base coat and ﬁnish coat. The degree of

correlation between these test methods and service perfor-

mance has not been determined.

5.6.2 Procedure—Select three 2 ft (600 mm) square speci-

mens. Raise each specimen and slam the back side (face not

treated with veneer plaster) on a bare concrete ﬂoor repeatedly

until the specimen is broken.

5.6.3 Report—Report whether the sample passes or fails the

bond test. The sample fails if the bond to the veneer base or

between the ﬁnish coast and base coat delaminates on any one

of the specimens.

5.6.4 Precision and Bias—No information is presented

about either the precision or bias of the bond test since the test

result is nonquantitative.

5.7 Impact Strength:

5.7.1 Signiﬁcance and Use—The impact strength is de-

signed to test the effect of impact from a hard object on the

surface of the veneer plaster. The degree of correlation between

this test method and service performance has not been deter-

mined.

5.7.2 Apparatus:

5.7.2.1 A stand with a solid, ﬂat base at least 2 ft (600 mm)

square with a means of holding the steel ball and releasing it

from a height of 36 in. above the base, without imparting

additional force.

5.7.2.2 A

⁄

in. (38 mm) diameter polished steel ball weigh-

ing 7.8 60.1 oz (221 63 g).

5.7.3 Procedure—Select one 2 ft (600 mm) square. Place

the specimen horizontally, with the plaster surface face up, on

the base of the apparatus . Drop the steel ball three times onto

different areas of the panel surface.

5.7.4 Report—Report whether the sample passes or fails the

impact test. The sample fails if there is a loss of bond or

cracking beyond the impact area on any one of the drops.

5.7.5 Precision and Bias—No information is presented

about either the precision or bias of the impact test since the

test result is nonquantitative.

5.8 Flexure:

5.8.1 Signiﬁcance and Use—The ﬂexure test is designed to

test the effect on the resistance to cracking and bond of the

veneer plaster to the veneer plaster base while being ﬂexed.

The degree of correlation between this test method and service

performance has not been determined.

5.8.2 Apparatus—Use the apparatus described in Test Meth-

ods C473 for Method B.

5.8.3 Procedure—Select three 12 by 16 in. (300 by

400 mm) specimens. Subject each specimen to a continuous,

midpoint, loading applied at a rate of 1 in./min 65s

(25 mm ⁄min 65 s) downward to the back of the panel (plaster

surface in tension) supported over a clear span of 14 in.

(356 mm) until failure.

5.8.4 Report—Report whether the sample passes or fails the

ﬂexure test. The sample fails if any one of the specimens shows

cracking more than

⁄

in. (13 mm) from the break line or if the

bond of the veneer plaster to the paper fails.

5.8.5 Precision and Bias—No information is presented

about either the precision or bias of the ﬂexure test since the

test result is nonquantitative.

5.9 Joint Strength:

5.9.1 Signiﬁcance and Use—The joint strength test is de-

signed to test strength of the joint between two adjacent

gypsum veneer panels that have been covered with veneer

plaster. The degree of correlation between this test method and

service performance has not been determined.

5.9.2 Apparatus—Use the apparatus described in Test Meth-

ods C473 for Method B.

5.9.3 Specimen Preparation—Cut two 8 by 12-in. (200 by

300-mm) pieces of gypsum base for veneer plaster for each

specimen to be tested. One 12-in. edge of each piece shall be

the paper-bound edge. Place the two pieces of gypsum base for

veneer plaster face down with the paper-bound edges forming

the joint. Apply a pregummed tape over the joint. (The tape

will keep the joint from ﬂexing during the specimen prepara-

tion.) Turn face up and apply joint tape and gypsum veneer

plaster in accordance with Speciﬁcation C843 using the

method titled “Reinforcement Secured and Embedded with

Veneer Plaster.”

5.9.4 Procedure—Condition the specimen and determine

the ﬂexural strength in accordance with Test Methods C473

Method B. Apply the load parallel to and directly over the back

of the joint.

5.9.5 Report—Calculate and report the average breaking

load in pound-force or newtons, rounded to the nearest 1 lbf

(N).

C587 − 04 (2018)

5.9.6 Precision and Bias—The precision and bias for mea-

suring joint strength are essentially as speciﬁed in Test Meth-

ods C473.

6. Inspection

6.1 Inspection of the gypsum veneer plaster shall be agreed

upon between the purchaser and the supplier as part of the

purchase agreement.

7. Rejection and Rehearing

7.1 Rejection of gypsum veneer plaster that fails to conform

to the requirements of this speciﬁcation shall be reported to the

producer or supplier promptly and in writing. The notice of

rejection shall contain a statement documenting how the

gypsum veneer plaster has failed to conform to the require-

ments of this speciﬁcation.

8. Certiﬁcation

8.1 When speciﬁed in the purchase agreement, a manufac-

turer’s or supplier’s report shall be furnished at the time of

shipment certifying that the product is in compliance with this

speciﬁcation.

9. Packaging and Package Marking

9.1 Gypsum veneer plaster shall be dry and free from lumps,

and shall be shipped in packages.

9.2 When shipped for resale, the following information

shall be legibly marked on each package or on a tag of suitable

size attached thereto:

9.2.1 Name of producer or supplier,

9.2.2 Brand,

9.2.3 Description, and

9.2.4 Net or gross weight, or both, of package.

10. Keywords

10.1 gypsum; gypsum veneer plaster; plaster; veneer plaster
