C Standards

This standard will provide minimum and optional function, layout, and construction requirements for standard control cabinet designs. It will also include a coding system for specifying standard control cabinets with the required options. This standard applies to Class I and Class II power...

This specification covers the composition, sizes, dimensions, and physical properties of cellular glass thermal insulation intended for use on surfaces operating at temperatures between −450 and 800°F (−268 and 427°C). It is possible that special fabrication or techniques for pipe...

This specification covers the classification and performance of flexible aerogel thermal insulation. This will cover the range of continuous exposure operating temperatures from -321°F (-196°C) up to 1200°F (649°C). For satisfactory performance, properly installed protective vapor...

This specification covers extruded preformed flexible cellular polyolefin thermal insulation operating temperatures from -150°F to 200°F (-101°C to 93°C). For specific applications, the actual temperature limit shall be agreed upon between the manufacturer and the purchaser. The use...

This guide covers the categories of anchors and anchoring systems and discusses the design principles to be considered in selecting anchors or systems that will resist gravity loads and applied loads. This guide sets forth basic requirements for the design of stone anchorage and provides a...

This guide provides information on how to compare the relative performance and potential incompatibility of combinations of concrete-making materials. Performance tests on fresh and early-age properties of mortar mixtures can be useful indicators of concrete performance using similar materials. The...

This test method covers the determination of the compressive strength of hydraulic cement grout for preplaced-aggregate (PA) concrete. The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact...

This specification covers ready-mixed concrete as defined in 3.2.2 (Note 1). Requirements for quality of ready-mixed concrete shall be either as stated in this specification or as ordered by the purchaser. When the purchaser's requirements, as stated in the order, differ from those in this...

This specification covers vapor retarders for thermal insulation, specifically, flexible materials with permeance of 0.15 perm (8.63 ng·Pa-1 · s-1 · m-2) or lower and surface burning characteristics of 25 flame spread/50 smoke or lower. These materials are intended for use at surface temperatures...

This guide covers recommended installation techniques for flexible closed cell pre-formed insulation in tube or sheet form. This guide is applicable to materials manufactured in accordance with Specification C534 (Elastomeric based insulation) or Specification C1427 (polyolefin based insulation)....

This specification covers aluminum jacketing for thermal and acoustical insulation operating at either above or below ambient temperatures and in both indoor and outdoor locations. It does not cover insulation jacketing made from other materials such as mastics, fiber reinforced plastic, PVC, or...

This practice covers procedures for making and curing cylinder and beam specimens from representative samples of fresh concrete for a construction project. The concrete used to make the molded specimens shall be sampled after all on-site adjustments have been made to the mixture proportions,...
