Industrial-process control valves. Part 8: Noise considerations. Section One: Laboratory measurement...
Defines equipment, methods and procedures for obtaining laboratory measurements of airborne sound-pressure levels radiated by control valves and/or associated piping configurations, including fixed restrictions, through which compressible fluids are passing. Provides a method of testing the noise-generating characteristics of control valves. The noise characteristics to be determined are useful…
Chemical products for industrial use — Sampling techniques — Solid chemical products in the form of ...
From the lot to be sampled a certain number of increments is taken. The increments are mixed to form either a bulk sample or several primary samples, depending on the purposes of the sampling. By means of replicate reductions a reduced sample is prepared from the bulk sample or from each primary sample, then several laboratory samples, each stage of the division being preceded in each case by…
Soils - Moisture-Density Relations Modified Proctor Test
The present standard describes the method to determine the relation between the
moisture content and the density of soils and soil aggregates when these are
compacted in standard moulds using 4,54 kg rammers dropped a height of 457 mm.
Four methods are described herein.
NOTE 1 - The laboratory compaction tests described in this standard generally
provide good measures of optimum moisture…
Testing Procedures for Seismic Qualification of CANDU Nuclear Power Plants
1. Scope
1.1 This Standard defines the consideration and requirements for performing an acceptable seismic qualification test and presents the different test methods that may be used.
Note: Selected safety related systems are required to be seismically qualified. (See CSA Standard CAN3-N289.1.) Qualification may be by analysis or testing, or a combination thereof, depending on the nature…
Apply only to the type of backflow preventer identified as
dual-check-valve type for use on residential supply service or
individual outlets. They also cover vacuum breakers for use on
laboratory faucets in nominal pipe size of 3/8 only, although
inlet or outlet connections, or both, may be different when so
required for special installations
