Development of standards for floor drains including floor, area, adjustable floor and trench drains which are used inside of, or outside and immediately adjacent to, building structures other than residential. This standard covers: a. Definitions b. Nomenclature c...
Description The device shall consist of a membrane that allows the flow of drainage to enter the plumbing drainage system. The device shall close when there is no flow. Size The device shall be sized according to the nominal pipe size of the device it installs into, except for the 3-1/2 in (DN 90)...
This Standard covers floor, area, adjustable floor, and trench drains that are used inside of, or outside and immediately adjacent to, building structures. This Standard specifies design requirements, definitions, nomenclature, outlet types and connections, grate-opening areas,...
This specification covers the material, design, structural performance, and manufacturing practice requirements for monolithic or sectional corrugated high density polyethylene (HDPE) grease interceptor tanks that are placed between commercial food service (kitchen) drains and sanitary sewer...
1.1 This specification covers high-silicon iron pipe and pipe fittings intended for corrosion-resistant service for both above- and below-grade construction. 1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI...
5.1 Vapor intrusion testing has been performed traditionally using multiple canister samples or thermal desorption tube samples. These discontinuous measurements have been shown to be snapshots and provide averages of exposure. In many cases a higher temporal resolution is desirable to identify...
This European Standard classifies roof drains and floor gullies without trap for use inside buildings, gives guidance for places of installation and specifies requirements for the construction, design, performance and marking as well as test methods of factory made roof drains...
