Astm c 1704 c 1704m 09a (2016)

Designation: C1704/C1704M − 09a (Reapproved 2016)

Standard Test Method for

Sampling and Testing Structural Cementitious Panels1

This standard is issued under the fixed designation C1704/C1704M; the number immediately following the designation indicates the

year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last

reapproval. A superscript epsilon (´) indicates an editorial change since the last revision or reapproval.

1. Scope

1.1 These test methods cover sampling and testing of

structural cementitious panels. Structural cementitious panels

are non-combustible, water durable, fiber reinforced inorganic

composite panels intended for use as structural panels when

fastened to supports spaced in accordance with the span rating

in inches.

1.2 These test methods are utilized in evaluating products

cited in Specification C1705/C1705M.

1.3 The values stated in either SI units or inch-pound units

are to be regarded separately as standard. The values stated in

each system may not be exact equivalents; therefore, each

system shall be used independently of the other. Combining

values from the two systems may result in non-conformance

with the standard.

1.4 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 appro￾priate safety and health practices and determine the applica￾bility of regulatory limitations prior to use.

3. Terminology

3.1 Definitions of Terms Specific to This Standard:

3.1.1 cross machine direction (XMD), n—the direction per￾pendicular to the machine direction.

3.1.2 edge, n—edges of a panel refer to the long side of a

rectangular panel. For example, on a 4 by 8 ft panel, the edges

refer to the sides of the panel that are 8 ft long.

3.1.3 end, n—the end of a panel refers to the short side of a

rectangular panel. For example, on a 4 by 8 ft panel, the end

refers to the side of the panel that is 4 ft long.

3.1.4 fiber reinforced inorganic composite, n—a composite

material composed primarily of inorganic matrix materials

reinforced primarily with inorganic fibers. Inorganic aggre￾gates may be combined with the inorganic matrix.

3.1.5 machine direction (MD), n—the direction the board

travels during manufacture.

3.1.6 non-combustibility, adj—term intended to describe

products that do not ignite and/or burn when subjected to fire.

Test methods are generally specified by reputable agencies

such as ASTM, Factory Mutual, Underwriters Lab Inc., and so

forth.

3.1.7 plant specification, n—the plant specification is unique

to each qualified product under a given performance standard.

The specification is used in the plant quality program as

audited under the approved quality control program.

3.1.8 performance standard, n—a standard for products

based on performance. Performance is measured by tests that

approximate end-use conditions.

3.1.9 qualification policy, n—policy that describes the pro￾cedures by which a plant may obtain span rating privileges for

performance-rated products policy.

3.1.10 quality assurance policy, n—policy covering the

third-party auditing of plant’s quality control program.

3.1.11 reference value, n—the numerical value established

for the plant specification for a given mechanical or physical

property.

3.1.12 sample average, n—the average test value, obtained

by summing the observations and dividing by the number of

tests.

3.1.13 sample panel, n—structural cementitious panel from

which test specimens are cut and conditioned as necessary.

3.1.14 sample standard deviation, n—a measure of test

variation, calculated as:

S 5 =@(x 2 2 ~(x! 2

/n#/n 2 1 (1)

where:

S = sample standard deviation,

1 This test method is under the jurisdiction of ASTM Committee C27 on Precast

Concrete Products and is the direct responsibility of Subcommittee C27.40 on Glass

Fiber Reinforced Concrete.
