This Standard provides for two general applications of Acme threads: namely, general purpose and centralizing. The limits and tolerances in this Standard relate to single-start Acme threads and may be used, if considered suitable, for multiple-start Acme threads. The latter...
GENERAL AND HISTORICAL When formulated prior to 1895, regular Acme screw threads were intended to replace square threads and a variety of threads of other forms used chiefly for the purpose of producing traversing motions on machines, tools, etc. For current information on Acme...
Defines Acme thread; tables of basic sizes, limits and tolerances for standard series of single start threads ¼ in to 5 in diameter. Agrees with ASA B1.5:1952 except for pitches associated with diameters ? in, 7/16 in, 1 in, 1¼ in and 1½ in. 2G, 3G and 4G fits in the American standard...
This document is to be used as a guide in preparing specifications for maintenance and inspection of acme screw assemblies used in driven linear actuators. It is intended to cover Acme screw assemblies driven by electric, hydraulic, pneumatic, manual means, with or...
For chemical and allied industries, where resistance to corrosion or cleanliness require special consideration. Dimensions, use of Acme screw thread, for butt-welded, expanded, recessed fittings. Illustrations, dimensions of preferred and non-preferred types of bends, tees, crosses....
Abstract This document specifies identifiers and challenges required to enable the Automated Certificate Management Environment (ACME) to issue certificates for IP addresses.
Abstract This document specifies a new challenge for the Automated Certificate Management Environment (ACME) protocol that allows for domain control validation using TLS.
Public Key Infrastructure using X.509 (PKIX) certificates are used for a number of purposes, the most significant of which is the authentication of domain names. Thus, certification authorities (CAs) in the Web PKI are trusted to verify that an applicant for a certificate legitimately represents...
Abstract Public key certificates need to be revoked when they are compromised, that is, when the associated private key is exposed to an unauthorized entity. However, the revocation process is often unreliable. An alternative to revocation is issuing a sequence of certificates, each with a short...
This specification covers a Modified Stub ACME Thread Joint with an Elastomeric Seal used to seal the joint components in plastic piping components, or (if applicable) to components made of other non-plastic materials used for plastic piping components used in turf irrigation systems. This...
Abstract The Certification Authority Authorization (CAA) DNS record allows a domain to communicate an issuance policy to Certification Authorities (CAs) but only allows a domain to define a policy with CA-level granularity. However, the CAA specification (RFC 8659) also provides facilities for an...
1.1 This specification covers a Modified Stub ACME Thread Joint with an Elastomeric Seal used to seal the joint components in plastic piping components, or (if applicable) to components made of other non-plastic materials used for plastic piping components used in turf irrigation systems. 1...
