ASTM C1860-23ce1(Test Method)
Standard Test Methods for Measurement of Tensile Strength or Bond Strength of Portland Cement-Based Plaster by Direct Tension

SIGNIFICANCE AND USE
4.1 The purpose of the test methods in this standard is to measure the tensile strength or bond strength of portland cement-based plaster to its substrate. The values obtained using the test methods are not purported to be representative of the actual wind load capacity or other structural properties of a specific portland cement-based plaster installation but may be helpful in assessing such load capacities.  
4.2 Because the test methods described in this standard are used for evaluation of portland cement-based plaster cured at least 28 days, load results obtained by either test method must be interpreted based on sound engineering practice, applicable building regulations, and codes having jurisdiction. The decision of whether to use the load results directly or to use the load results as modified by an appropriate safety factor to obtain acceptable working loads is left to the discretion of the test specifier. Determination of an appropriate safety factor shall be left to the discretion of the test specifier. Methods to calculate a safety factor and a maximum permitted working load are provided in the appendixes.  
4.3 When the test methods contained in this standard are used on test specimens installed on existing structures, the test results shall not be generalized to a larger wall area without sufficient test sampling. Such efforts should be based on engineering experience and judgment of the test specifier.
SCOPE
1.1 These test methods cover procedures for determining the tensile strength of a section of portland cement-based plaster, the bond strength between portland cement-based plaster and a solid plaster base, or the fastener pull-out or lath pull-over strength for portland cement-based plaster bases over framing in either an exterior (stucco) or interior application. The test procedures are destructive in nature within the localized test areas and, after testing is concluded, require appropriate repair of the finish system as well as any underlying materials damaged during testing.  
1.2 These test methods are suitable for use on portland cement-based plaster finish systems on both new and existing construction. Test methods shall be conducted a minimum of 28 days after application of the portland cement-based plaster. Mechanical Load Test Method A and Vacuum Chamber Testing shall be used to determine the tensile strength or bond strength of direct-applied portland cement-based plaster and may be useful in evaluating the efficacy of different surface preparation characteristics, bonding agents, or both. Mechanical Load Test Method B and Vacuum Chamber Testing shall be used to determine the tensile strength of portland cement-based plaster installed over mechanically attached lath.  
1.3 These test methods are suitable for use in both laboratory and field samples. No correlation shall be made between laboratory and field testing.  
1.4 These test methods are not intended to evaluate the performance of the underlying construction or framing members. Test results on a particular building may be variable depending on the specimen location, condition, and installation, and are subject to interpretation by the test specifier.  
1.5 These test methods are not intended to evaluate the performance of coatings applied to the surface of the portland cement-based plaster.  
1.6 These test methods are not intended to be a pre-construction qualifier to determine if the surfaces are appropriate for application of portland cement plaster. The test methods are intended to be used as a tool to quantitatively evaluate existing portland cement plaster cladding that is suspected of questionable bond or uncertain fastening to the substrate.  
1.7 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.8 This standard may involve...

Standard Classification for Abuse-Resistant Nondecorated Interior Gypsum Panel Products and Fiber-Reinforced Cement Panels

SIGNIFICANCE AND USE
4.1 Each abuse/impact property of abuse resistant wall panels is divided into three classification levels. The three levels of classification are: Level I, Level II, and Level III, with Level I representing the lowest rating for any given property. The test methods specified are utilized to establish the abuse-resistance classification of an abuse resistant wall panel. Each classification level requires a minimum overall specified performance. Any classified abuse resistant wall panel can be used at a classification level which is rated lower than the highest level qualified.
SCOPE
1.1 This standard establishes classifications of abuse resistance based on the abrasion resistance and impact resistance performance of nondecorated interior gypsum panel products and fiber-reinforced cement panels (abuse resistant wall panels).  
1.1.1 This standard is a method of classifying gypsum panel product performance and is not intended to classify systems for abuse resistance.  
1.2 The values stated in inch-pound and SI (metric) units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system shall be used independent of the other. Values from the two systems shall not be combined.  
1.3 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 regulatory limitations prior to use.

Standard Specification for Installation of Interior Lathing and Furring

ABSTRACT
This specification covers the minimum requirements for, and the methods of application of, interior lathing and furring to receive gypsum plaster applied. Other materials are not prohibited from being used provided that their physical characteristics and durability under conditions of usage are at least equal in performance to those described. All materials shall be kept dry, preferably by being stored inside. Where necessary to be stored outside, materials shall be stacked off the ground, supported on a level platform, and protected from the weather and surface contamination. Materials shall be neatly stacked flat with care taken to avoid damage to edges, ends, or surfaces. The materials to be used are the following: tie wire and hanger wire, gypsum lath, expanded metal lath, welded wire lath, woven wire lath, nails, screws, staples, paper, and accessories such as control joints, cornerite, channels, rod and flat hangers, clips, and striplath. In general, during installation, the following shall be required: application of gypsum lath to supports, application of gypsum lath to wood supports, application of gypsum lath to metal supports, studless solid partitions (gypsum lath and plaster), application of metal plaster bases to framing members, studless solid partitions (metal lath and plaster), suspended and furred ceilings (metal lath and gypsum lath construction), main runners, cross furring, and metal furring for walls.
SCOPE
1.1 This specification covers the minimum requirements for, and the methods of application of, interior lathing and furring to receive gypsum plaster applied in accordance with Specification C842.
