Standard Test Methods for Sampling Wood Preservatives Prior to Testing (Withdrawn 2006)
SCOPE
1.1 These test methods cover sampling of creosote, creosote-coal tar solutions, creosote-petroleum solutions, and oilborne and waterborne preservatives. Note 1-See Specification D390, for Coal-Tar Creosote for the Preservative Treatment of Piles, Poles, and Timbers for Marine, Land, and Fresh Water Use, Specification D391 for Creosote-Coal Tar Solution, and Specification D1858, for Creosote-Petroleum Solution.
1.1.1 Creosote and creosote solutions are homogeneous liquids, except for their moisture content. At atmospheric temperatures, however, part of the creosote is usually in crystalline form, and shall be heated to a temperature at which it is entirely liquid before sampling.
1.1.1.1 When sampling creosote and creosote solutions, the object is to obtain a sample that will be representative of the water content, and the methods of sampling described are intended to accomplish that purpose.
1.1.2 Recommended test methods are given for sampling a preservative in a liquid or solid state and in the several types of containers in which they are likely to be encountered. Creosote, creosote-coal tar, and creosote-petroleum solutions may be in the form of a liquid or semiliquid. Oilborne and waterborne preservatives may be in the solid state, in concentrated solutions, or in ready-to-use solutions.
1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
WITHDRAWN RATIONALE
These test methods cover sampling of creosote, creosote-coal tar solutions, creosote-petroleum solutions, and oilborne and waterborne preservatives.
Formerly under the jurisdiction of Committee D07 on Wood, these test methods were withdrawn with no replacement in July 2006.

method, however, is to obtain a sample or a composite of
several samples in such manner and from such locations in the
container that the sample or composite will be truly represen-
tative of the material being sampled.
4. Apparatus
4.1 Continuous-Drip Sampling:
4.1.1 Line Connection constructed substantially as shown
in Fig. 1 shall be inserted in the pipeline through which the
preservative is being transferred, preferably on the discharge
side of the pump. The sampling pipe shall be provided with a
valve.
4.1.2 Receiver—Use a clean, dry container of convenient
size to receive the sample. The container shall be covered with
a lid to protect the sample from foreign contamination.
