ASTM E935-21

4.1?These test methods are intended to provide information from which applicable design and performance data can be derived for the performance of metal railing systems and rails installed and fastened to structural elements of concrete, masonry, wood, and metal as well as related products.

4.2?These test methods may be used to determine whether railing systems comply with requirements of the applicable performance specifications.

4.3?These test methods are intended for use in the buying and selling of railing systems and components according to performance specifications, for use in product development research, for use in quality assurance and manufacturing process control, for use in developing performance standards, and for use in field and laboratory compliance determination. Typical floor-mounted railings are shown in Fig. 1.

1.1?These test methods cover procedures to be followed in testing the performance of permanent metal railing systems (guard, stair, and ramp-rail systems), including components such as rails (hand, wall, grab, and transfer rails) and swing gates or other forms of required guardrail opening protection, installed in and for agricultural, assembly, commercial, educational, industrial, institutional, recreational, and residential buildings and other structures, such as towers or elevated platforms.

1.2?These test methods are applicable to such railing systems and rails having major structural components made of metal, with their secondary components, including swing gates or other forms of guardrail opening protection, made of metal or other materials such as wood, plastic, and glass.

1.3?These test methods can be used to determine whether permanent metal railing systems and rails,1.4?Specifically, these test methods cover procedures for determining the static strength of metal railing systems, rails and components as structural elements when installed and fastened to concrete, masonry, wood, and metal, as well as related products.

1.5?No consideration is given in these test methods to any possible deterioration of metal railing systems, rails, and connections, resulting from adverse environmental conditions. The performance of special tests covering this aspect may be desirable.

1.6?These test methods are limited to the application of the loads described herein.

1.7?Should computations make it possible to provide the needed information, testing can be employed for verification.

1.8?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.

1.9?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. 1.10?This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
