1.1 The sound isolation between two spaces in a building is influenced most strongly by a combination of the direct transmission through the nominally separating building element (as normally measured in a laboratory) and any transmission along a number of indirect paths, referred to as flanking...
5.1 The noise reduction of an enclosure is a property of the enclosure, the location of the sound source used to measure noise reduction, and the space in which the enclosure is placed. It is not a property of the enclosure alone, and its measurement under different conditions can be expected to...
1.1 This classification covers methods of calculating single-number acoustical ratings for laboratory and field measurements of sound attenuation obtained in one-third octave bands. 1.2 The name given to the single-number rating is assigned by the test method that invokes this classification. 1.3...
Cross-laminated timber (CLT) has long been heralded as a wonder material, with a light environmental footprint, high strength, quick installation times and reduced waste - so why isn't everyone using it? Delving into the key considerations including fire safety, cost and value, visual aspects,...
This method is for determining total mercury in liquid hydrocarbons using a Nippon Instruments Corporation (NIC) Mercury Analyzer. The lower limit of quantitation is 0.1 ng/mL (m/v-ppb). The results can be converted to mass-ppb. Appendix A contains a procedure, Determination of Mercury...
This method is for determining the total mercury concentration in liquefied petroleum gases, using a Nippon Instrument Corporation (NIC) WA-5F mercury analyzer with a NIC LP-WA vaporizer and dry gas meter (DCDa-1C) with a lower limit of quantification of 0.1 mass ppb. Mercury is...

5.1 The test method supports previously proposed occupational exposure standards (7, 8) for DPM. A DPM exposure limit has since been promulgated for metal and nonmetal mines, but there currently are no limits for general occupational settings (a proposed limit (7) was withdrawn from the ACGIH...
5.1 The main part of this standard uses procedures originally developed for laboratory measurements of the sound transmission loss of partitions. These procedures assume that the rooms in which the measurements are made have a sound field that reasonably approximates a diffuse field. Sound pressure...

It is intended that ARINC 600 be used with the application and customer needs in mind. To enhance the breadth of use, this document alludes to three phases defined as follows: a. Phase I - This phase specifies the definitions, guidance, and appraisals given in Section 1.1 for those instances in...

This method is for determining total mercury in solid materials using a Nippon INstruments Corporation (NIC) MA-3000 Mercury Analyzer. The instrument uses a dual path detector to measure from the lower limit of 0.1 ng/g (mass-ppb) to an upper limit of 500 μg/g (mass-ppm), when analyzing a 50...
