Published by: American Society for Quality / 2013 / 213 pages
About Z1.4-2003 (R2013):
Sampling Procedures and Tables for Inspection by Attributes is an acceptance sampling system to be used with switching rules on a continuing stream of lots for AQL specified. It provides tightened, normal, and reduced plans to be applied for attributes inspection for percent nonconforming or nonconformities per 100 units.

About Z1.9-2003 (R2013):
Sampling Procedures and Tables for Inspection by Variables for Percent Nonconforming is an acceptance sampling system to be used on a continuing stream of lots for AQL specified. It provides tightened, normal, and reduced plans to be used on measurements which are normally distributed. Variation may be measured by sample standard deviation, sample range, or known standard deviation. It is applicable only when the normality of the measurements is assured.

Non-Real-Time, High-Integrity Software for the Nuclear Industry – Developer Requirements

Published by: American Nuclear Society / 03/18/2013 / 30 pages
This standard provides minimum requirements for assurance that high-integrity software developed for use by the nuclear industry meets state-of-the-practice expectations for quality. The requirements in this standard are specified for development of high-integrity sofware. The intent is to set a minimum level of quality assurance and critical technical process requirements to satisfy due diligence.

This standard addresses rigorous, systematic development of high-integrity, non-real-time safety analysis, design, and simulation software that includes calculations or simulations requiring high functional reliability in order to avoid undetected errors tha could have serious consequences if such errors are not detected (the scope of this standard does not include electronic procedures).

Control Valve Seat Leakage

Published by: Fluid Controls Institute / 2013 / 9 pages
This standard establishes six classes of seat leakage for control valves. Also defined are specific test procedures to determine the appropriate class. Included are classes commonly associated with double-port, double-seat or balanced single-port control valves with a piston ring seal or metal-to-metal seats; commercial unbalanced single-port, single-seat and balanced single-port valves with extra tight piston rings or other sealing means and metal-to-metal seats; valves for critical applications where the control valve may be required to be closed, without a blocking valve, for long period of time; and resilient seating control valves
with “O” rings or similar gapless seals, among others.

IEST RP-PR003.1

HALT and HASS

Published by: Institute of Environmental Sciences and Technology / 2012 / 23 pages
This Recommended Practice (RP) defines and describes HALT (Highly Accelerated Life Testing) and HASS (Highly Accelerated Stress Screening). This RP contains information on the philosophy behind the testing, generic examples of tests, the differences between standard testing equipment and equipment used for highly accelerated testing, fixturing consid-erations, alternative approaches, additional environments, and lessons learned, along with other useful information. This style of testing takes a Qualitative approach (looking for the quality of the design and workmanship) rather than a Quantitative approach (being able to use the results to calculate length of life in service). This RP is not meant to take the place of a test specification but to be used in conjunction with a test specification or as general guidance.
