PTC 38 - Determining the Concentration of Particulate Matter in a Gas Stream

The Test object is to determine the weight rate of flow of particulate matter carried in a gas stream confined in a duct or stack. The test object is accomplished by (a) measurement of average weight concentrations of particulate matter in the gas stream, and (b) determination of total gas flow rate. Data thus obtained may be utilized for such purposes as the performance evaluation of gas cleaning apparatus systems, compliance testing in conjunction with emission control and performance regulations promulgated by regulatory agencies, etc. 1.21 Concentration of Particulate Matter This Code prescribes methods for measuring the average weight concentration of particulate matter carried in a gas stream. Measurement on any other basis (e.g., particle count, dust spot, opacity, etc.) is beyond the scope of this Code. 1.23 Particle Size Measurement The scope of this Code does not include the measurement of particle size distribution. Test procedures for this purpose are contained in ASME Performance Test Code 28.

 

B30.6 - Derricks

Applies to the construction, installation, operation, inspection, and maintenance of guy, stiffleg, basket, breast, gin pole, Chicago boom, shearleg, and A-frame derricks of the stationary type, capable of handling loads at variable reaches and powered by hoists through systems of rope reeving used to perform lifting hook work. Derricks may be permanently installed or installed for temporary use as in construction work. The requirements of B30.6 also apply to any modification of these types which retain their fundamental features, except as specified for floating derricks in ASME/ANIS B30.8, Floating Cranes and Floating Derricks.

 

PTC 2 - Definitions and Values Code

This Code contains standards for terms, units of measure, values of constants, symbols, and technical nomenclature that are to be used in all individual test codes. The implication of the words "must," "shall," and "will" is mandatory. The use of "should," "would," and "ought" denotes recommended practice. All the information contained herein represents the state of the art at the time of its preparation. In order that the PTC may continue to be useful, any part of this Code is automatically superseded by any of the following actions: (a) approval of new or revised units, values of physical constants, or fluid properties; (b) inclusion of equipment not covered by this Code in the PTC series; or (c) approval by the Board on Performance Test Codes of a new Code not conforming to this document.

 

A112.18.7 - Deck Mounted Bath/Shower Transfer Valves

This Standard establishes requirements for deck mounted, bath/shower transfer valves with integral back-flow protection on the secondary outlets. It covers physical and performance requirements, test methods, and requirements for marking and identification. The provisions of this Standard are not intended to prevent the use of any alternative material or method of construction, provided any such alternative meets the intent of this Standard.

 

Y14.1 - Decimal Inch Drawing Sheet Size and Format

This Standard defines decimal inch sheet sizes and formats for engineering drawings

 

PTC 12.3 - Deaerators

The purpose of this Code is to provide rules and test procedures that are to be used to determine the performance of deaerators with regard to the following: (a) residual dissolved oxygen in the deaerated water, (b) terminal temperature difference (TTD), if any, between the deaerated water and the saturated steam temperature corresponding to the pressure in the steam zone adjacent to the interface between the steam and the collected deaerated water. This Code applies to deaerating heaters and deaerators equipped with either shell-and-tube or direct contact, vent-condensing sections.

 

B107.30 - Cross Tip Screwdrivers

This Standard covers straight handle-type screwdrivers of PHILLIPS and POZIDRIV design intended for manual operation in driving or removing screws with PHILLIPS?? or POZIDRIV recesses. The screwdrivers are of the types normally used by cabinetmakers, carpenters, sheet metal workers, production workers, mechanics, etc. The intention is to specify performance rather than design detail. Inclusion of dimensional data in this Standard is not intended to imply that all of the products described herein are stock production sizes. Consumers are requested to consult with manufacturers concerning lists of stock production sizes. Using a screwdriver as a pry bar or striking it with a hammer are clearly misuses of the tool, and nothing in this Standard shall be interpreted as condoning any tool misuse. Further information about proper use of screwdrivers is contained in the Guide to Hand Tools-Selection, Safety Tips, Proper Use and Care.

 

BOI - Criteria of ASME Boiler & Pressure Vessel Code Design by Analysis Sections III & VIII Division 2

This document provides an explanation of the strength theories, stress categories, and stress limits on which these design procedures are presently based. It also provides an explanation of the methods used for determining the suitability of vessels and parts for cyclic application of loads.

 

CSD-1 - Control and Safety Devices for Automatically Fired Boilers

The rules of this code cover requirements for the assembly,maintenance,and operation of controls and safety devices installed on automatically operated boilers directly fired with gas, oil, gas-oil, or electricity, subject to certain service limitations and exclusions. Use of a gaseous or oil fuel not listed in the definitions has not been evaluated and special considerations may be required. Exclusions (a) Boilers with fuel input ratings of 12,500,000 Btu/hr (3 663 389 w) or above, falling within the scope of NFPA 8501, NFPA 8502, NFPA 8503, and NFPA 8504. (b) Water heaters.

 

B30.3 - Construction Tower Cranes

Applies to the construction, installation, operation, inspection, and maintenance of construction tower cranes, powered by electric motors or internal combustion engines, and any variations thereof which retain the same fundamental characteristics. The scope includes cranes of the above type that that adjust operating radius by means of a boom luffing mechanism, or by means of a combination of the two. Construction tower cranes may be mounted on fixed or traveling bases. Additional mounting means may include arrangements that permit the crane to climb in the structure being built, or that permit increasing the tower height as the structure rises and utilizing braces attached to the host structure as needed. The requirements of this volume are applicable only to cranes when used in lifting work. Permanently mounted tower cranes (refer to ASME B30.4) and mobile crane tower attachments (refer to ASME B30.5) are not within the scope of this volume.
