Standard edition method

Several countries have developed their own standard test methods for cellular plastics, and the International Organization for Standards (ISO) Technical Committee on Plastics TC-61 has been developing international standards. Information concerning the test methods for any particular country or the ISO procedures can be obtained in the United States from the American National Standards Institute. The most complete set of test procedures for cellular plastics, and the most used of any in the world, is that developed by the ASTM these procedures are pubUshed in new editions each year (128). There have been several reviews of ASTM methods and others pertinent to cellular plastics (32,59,129—131). 

Specifications and Standards Test Methods. Pood-grade HPC products are manufactured for use in food and conform to the specifications for HPC set forth in CPR 21, Section 172.870. Pood grades of HPC also conform to the specifications for HPC as Usted in the current edition of the Food Chemicals Codex.

In the original work, triplicate determinations of the fat content of each sample were performed and the standard deviations (SD) were calculated. The empirical values obtained by MAP proved to be statistically equivalent to values obtained by the official agency that provided the meat standards. The method used to certify the samples were AOAC methods 24.005 and 7.056 (13th edition, 1980) which are based upon a four-hour extraction of the dried sample with petroleum ether using a Goldfisch or a Soxhlet extractor. 

The Japanese Pharmacopoeia (JP). The main and oldest document specifying standards for drugs is the Japanese Pharmacopoeia, first published in 1886. The JP is established by law (Article 41). It aims at regulating quality for important drugs used in healthcare and specific standard test methods. The JP is revised by law every 10 years, but in practice the revision is carried out every 5 years. The Thirteenth Edition was published in 1996 and already contains some monographs harmonized with the US and European Pharmacopoeias. 

In preparing this chapter, the aim of the author has been to provide a guide to the standardized practical methods. Since electrical measurement is the province of the International Electrotechnical Commission (lEC). lEC standards have been preferred to ISO when both are in existence. Reference has also been made to a number of review papers with extensive bibliographies. If more fundamentally oriented discussion is required, the first volume of the handbook edited by Barnikas and Eichhorn is recommended [I]. 

Liquid means a material that has a vertical flow of over two inches (50mm) within a three-minute period, or a material having one gram or more liquid separation, when determined in accordance with the procedures specified in ASTM D 4359-84, Standard Test Method for Determining Whether a Material is a Liquid or a Solid, 1990 edition, which is incorporated by reference.

Great care must be taken in obtaining the latest edition of standards, reading them carefully and paying attention to detail. Poor testing technique invariably leads to poor test results being obtained. It is always best to test to an existing published standard test method if possible, preferably one from ISO. 

Determinarion of MW and MWD by SEC using commercial narrow molecular weight distribution polystyrene as calibration standards is an ASTM-D5296 standard method for polystyrene (11). However, no data on precision are included in the 1997 edition of the ASTM method. In the ASTM-D3536 method for gel-permeation chromatography from seven replicates, the M of a polystyrene is 263,000 30,000 (11.4%) for a single determination within the 95% confidence level (12). A relative standard deviation of 3.9% was reported for a cooperative determination of of polystyrene by SEC (7). In another cooperative study, a 11.3% relative standard deviation in M, of polystyrene by GPC was reported (13). 

The API Standard 4F, First Edition, May 1, 1985, API Specifications for Drilling and Well Servicing Structures, was written to provide suitable steel structures for drilling and well servicing operations and to provide a uniform method of rating the structures for the petroleum industry. API Standard 4F supersedes API Standards 4A, 4D, and 4E thus, many structures in service today may not satisfy all of the requirements of API Standard 4F [2-5].
