Requirements for position of the weld metal moisture content of low-hydrogen electrode coverings standard sizes and lengths marking manufacturing and packaging are also included.A guide to the use of the standard is included in an annex. Optional supplemental requirements include improved toughness and ductility lower moisture contents and diffusible hydrogen limits. This specification makes use of both U.S.Customary Units and the International System of Units(SI).Since these are not equivalent each system must be used independently of the other.

SCOPE 1.1. The liquid limit of a soil is that water content as determined in accordance with the following procedure at which the soil passes from a plastic to a liquid state. 1.2. The following applies to all specified limits in this standard:For the purposes of determining conformance with these specifications an observed value or a calculated value shall be rounded off“to the nearest unit'"in the last right-hand place of figures used in expressing the limiting value in accordance with ASTM E29. 1.3. The quality of the results produced by this standard are dependent on the petence of the personnel performing the procedure and the capability calibration and maintenance of the equipment used.Agencies that meet the criteria of R 18 are generally considered capable of petent and objective testing/sampling/inspection/etc.Users of this standard are cautioned that pliance with R 18 alone does not pletely assure reliable results.Reliable results depend on many factors;following the suggestions of R 18 or some similar acceptable guideline provides a means of evaluating and controlling some of those factors. 2.

SCOPE 1.1. This method covers the determination of specific gravity and absorption of coarse aggregate. The specific gravity may be expressed as bulk specific gravity bulk specific gravity (saturated surface-dry (SSD)) or apparent specific gravity.The bulk specific gravity (SSD)and absorption are based on aggregate after 15-19 h of soaking in water.This method is not intended to be used with lightweight aggregates. 1.2. The values stated in SI units are to be regarded as the standard. 1.3. This standard may involve hazardous materials operations and equipment.This standard does not purport to address all of the safety concerns associated with its use.It is the responsibility of the user of this procedure to consult and establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to its use. 1.4. The quality of the results produced by this standard are dependent on the petence of the personnel performing the procedure and the capability calibration and maintenance of the equipment used.Agencies that meet the criteria of R 18 are generally considered capable of petent and objective testing/sampling/inspection/etc.Users of this standard are cautioned that pliance with R 18 alone does not pletely assure reliable results.Reliable results depend on many factors;following the suggestions of R 18 or some similar acceptable guideline provides a...
