2.1 This practice is to be used to determine the length of a dip tube of a mechanical pump dispenser that extends to the bottom-corner of a container.2.2 This practice is to be used to determine the length of a dip tube of a mechanical pump dispenser that extends to the bottom-center of a container.1.1 This practice covers the determination technique for a dip tube of a mechanical pump dispenser.1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the 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.

AbstractThese practices describe procedures for the preparation of hot-dip aluminum surfaces for painting. Two types of surface preparation are included: solvent cleaning and chemical treatments. Solvent cleaning of the surfaces may be done by any of the following methods: manual swabbing or dip washing with a solvent such as mineral spirits or high flask solvent naphtha, solvent spray cleaning, and vapor degreasing in special equipment. On the other hand, surface preparation of aluminum for painting may be achieved by any of the following chemical treatment methods: use of alkaline cleaners, use of alcoholic phosphoric acid cleaners, use of acid fluoride deoxidizer, crystalline phosphate treatment, amorphous phosphate treatment, carbon chromate treatment, amorphous chromate treatment, and acid-bound resinous treatment.1.1 These practices describe procedures for the preparation of hot-dip aluminum surfaces for painting.1.2 This standard may involve hazardous materials, operations, and equipment. 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.1.3 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 sheet steel in coils and cut lengths coated with lead-tin alloy by the hot-dip process. The material, also known as terne-coated sheet, is available in four designations as commercial steel, deep drawing steel, extra deep drawing steel, and structural steel. Amount of copper, nickel, chromium, molybdenum, vanadium, titanium, columbium, and boron shall conform to the chemical composition requirements of this specification. Yield strength, tensile strength, elongation, and bending shall conform to the mechanical property requirements.1.1 This specification covers sheet steel in coils and cut lengths coated with lead-tin alloy (terne metal, see 3.2.3) by the hot-dip process. This material is commonly known as terne and is used where ease of solderability and a degree of corrosion resistance are desirable. It is especially suitable where resistance to gasoline is required. Terne-coated sheet is also used for stamping, where the coating acts as a lubricant in the die, lessening difficulties in drawing. The weight of coating, always expressed as total coating on both sides, shall be specified in accordance with Table 1.1.2 Material furnished under this specification shall conform to the applicable requirements of the latest issue of Specification A924/A924M, unless otherwise provided herein.1.3 Terne-coated steel is available in a number of designations, types, and grades.1.4 This specification is applicable to orders in either inch-pound units (as A308) or SI units (as A308M). Values in inch-pound and SI units are not necessarily equivalent. Within the text, SI units are shown in brackets. Each system shall be used independently of the other.1.5 Unless the order specifies the “M” designation (SI units), the product shall be furnished to inch-pound units.1.6 The text of this specification references notes and footnotes that provide explanatory material. These notes and footnotes, excluding those in tables and figures, shall not be considered as requirements of this specification.1.7 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.
