5.1 The ability to collect an infrared spectrum of a liquid paint as supplied in the container from the manufacturer is of significant importance when performing qualification testing. Historically, fingerprinting a material for such purpose involved separating the components of the paint and collecting an infrared spectrum of one or more of these components (vehicle, pigments, solvent, etc.) with Test Method D2621 being used for the identification of the vehicle. This unfortunately provides information only on the portion of the liquid paint analyzed whereas the technique shown in this practice provides a more complete picture of what is in the container provided. In addition, user expertise and time required to collect a spectrum is minimal versus traditional standards.1.1 This guide covers the FT-IR fingerprinting of a liquid paint as supplied in the container without the need to separate components. Spectra collected using this technique have been found useful for paint manufacturers' quality control, trouble shooting and to verify that the paint being used is the same as the paint sample tested. This technique has been found useful for both single and multi-component coatings, the latter of which, where each component is analyzed separately (for example, amine cured epoxies and polyol/isocyanate urethanes).1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.3 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This specification covers corrugated and solid fiberboard sheet stock (container grade) and cut shapes intended for use mainly in the fabrication of boxes and interior details (for example, pads, sleeves, liners, partitions, and die-cut sheets). Covered in this specification are three classes (domestic and domestic/fire retardant, weather resistant and weather resistant/fire retardant, and water and water-vapor resistant and water and water-vapor resistant/fire retardant) of corrugated fiberboard and two classes (domestic and domestic/fire retardant, and weather resistant and weather resistant/fire retardant) of solid fiberboard, with a variety of grades reflecting the varied performance levels of the fiberboards. Corrugated fiberboards shall be manufactured with two, three, or four facings for single-, double-, or triple-wall varieties, respectively, with each facing separated by and securely adhered to the corrugating medium of any suitable fiber. Solid fiberboards, on the other hand, shall be manufactured from plies securely and continuously laminated together. The facings of corrugated fiberboards and plies of solid fiberboards shall conform to the requirements specified. Tests for thickness, basis weight, puncture resistance, ply separation, bursting strength, flame spread, specific optical density, and edge crush shall be performed and shall conform to the requirements specified.1.1 This specification covers fiberboard primarily used for the fabrication of boxes and interior details such as pads, sleeves, liners, partitions, die-cut sheets, etc.1.2 The performance of fiberboard boxes is largely dependent on the paper components from which they are fabricated and, in the case of corrugated boxes, on the flute structure as well. Therefore, a variety of grades reflecting varied performance levels are specified.1.3 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. See IEEE/ASTM-SI-10 for conversion of units.1.4 The following safety hazards caveat pertains only to the test portion, Sections 8 and 9, of this specification: 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

4.1 Spoilage of paint in the container can result in putrefaction, lowered pH, gas formation, and decrease in viscosity. This test method provides a standard procedure for the evaluation of the resistance of emulsion paints to microbial deterioration. The results should enable: (1) the paint manufacturer to select an effective preservative and (2) the supplier of preservatives to evaluate the performance in emulsion paints of competitive and developmental preservatives.4.2 This test method should be used preferably by persons who have had basic microbiological training.NOTE 1: The reliability of the results obtained from this test method is extremely dependent on the techniques employed. Improper techniques can result in a sterile sample appearing to be contaminated, and even worse, a contaminated sample appearing to be sterile (see also Note 2). It is recommended that you consult with your biocide supplier, raw material supplier, or an independent testing laboratory to confirm questionable results. Formulation and raw materials’ quality may also vary and thereby affect the test results.1.1 This test method covers the determination of the relative resistance of emulsion paints to attack in the container by microorganisms.1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.1.3 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Plans for sampling and analysis of nuclear material are designed with two purposes in mind: the first is related to material accountability and the second to material specifications. For the accounting of special nuclear material, sampling and analysis plans should be established to determine the quantity of special nuclear material held in inventory, shipped between buyers and sellers, or discarded. Likewise, material specification requires the determination of the quantity of nuclear material present. Inevitably there is uncertainty associated with such measurements. This practice presents a tool for developing sampling plans that control the random error component of this uncertainty. Precision and accuracy statements are highly desirable, if not required, to qualify measurement methods. This practice relates to“ precision” that is generally a statement on the random error component of uncertainty. 1.1 This practice provides an aid in designing a sampling and analysis plan for the purpose of minimizing random error in the measurement of the amount of nuclear material in a lot consisting of several containers. The problem addressed is the selection of the number of containers to be sampled, the number of samples to be taken from each sampled container, and the number of aliquot analyses to be performed on each sample. 1.2 This practice provides examples for application as well as the necessary development for understanding the statistics involved. The uniqueness of most situations does not allow presentation of step-by-step procedures for designing sampling plans. It is recommended that a statistician experienced in materials sampling be consulted when developing such plans. 1.3 The values stated in SI units are to be regarded as the standard. 1.4 This standard does not purport to address all of the safety problems, 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.

5.1 These test methods are used to demonstrate whether an adhesive preparation is sufficiently protected with biocide to resist attack by bacteria, yeast, and fungi during its storage life. They are patterned after methods used by biological laboratories serving the adhesive industry.5.2 These test methods may also be used to determine the efficacy of different biocide systems against specific microorganisms.5.3 These test methods are especially useful when tested against wild-type microorganisms which have been isolated from contaminated adhesives as an aid in determining the amount and type of biocide necessary to kill or inhibit the growth of the contaminants. If an isolated microorganism not generally used as a challenge organism, is chosen as the inoculum, it is important to identify the organism and determine on which medium and under what conditions it will grow, in order to demonstrate the efficacy of the biocide.5.4 The results obtained when using the procedures given in these methods apply only to the species which are used for the testing. The test species listed in Section 9 are frequently used by laboratories to test for antimicrobial properties, but they are not the only ones which could be used. Selection of the species to use for these test methods requires informed judgment by the testing laboratory or by the party requesting the tests. It is also important that species which commonly attack adhesives be used. See 9.4.5.5 The presence of an active biocide carried over from the adhesive specimen to the agar could have an inhibiting effect on the growth of microorganisms, resulting in no growth during the span of a normal incubation period, when in fact, viable microorganisms are present, but their growth has been slowed down or held in stasis. The use of Letheen agar and broth is recommended to neutralize the effect of this carry-over.NOTE 4: Letheen agar may be used for the streak plates, or if another agar is chosen for testing, a Letheen agar plate could be streaked as a control to test against the neutralizing effect. Even more effective would be diluting the challenged adhesive specimen with Letheen broth and running Letheen agar pour plates. See Note 1 and Note 3. Extending the incubation period of negative plates would be another safeguard. To neutralize thiazoline-based preservatives, 10 to 50 ppm of sodium thioglycolate can be added to the medium.5.6 These test methods are dependent upon the physiological action of living microorganisms under a reported set of conditions. Conclusions about the resistance of the test adhesive to microbiological attack can be drawn by comparing the results to simultaneously run controls of known resistance. See X5.2 for statements regarding test repeatability.1.1 These test methods cover the determination of the resistance of liquid adhesive preparations to microbial attack in the container by challenging adhesive specimens with cultures of bacteria, yeast, or fungi, and checking for their ability to return to sterility. These test methods return qualitative results.1.2 The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only.1.3 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. These test methods are designed to be used by persons trained in correct microbiological technique. Specific precautionary statements are given in Section 8.1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

4.1 Sampling of decorated glass containers for the TCLP can vary greatly, resulting from the size and shape of the article relative to the amount of ceramic decoration on the ware. Breaking the glass can cause some of the pieces to have no decoration on them, and others to be heavily decorated and more likely to leach lead and cadmium under the TCLP test. This method provides an effective tool to homogenize the glass containers so that reproducible results can be attained from the TCLP test.1.1 This test method defines the way in which container glassware should be prepared before performing the Toxicity Characteristic Leaching Procedure (TCLP). The method covers the homogenization of the sample, and the selection of a representative portion of the sample to test and get reproducible results.1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.3 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
