ASTM D5264-2019 Standard Practice for the Wear Resistance of Sutherland Friction Testers to Printed Materials

Meaning and use 5.1 Wear resistance is a desirable and sometimes critical characteristic of printed materials. Wear and tear may occur during transportation, storage, handling and end use. The result is a significant decline in product appearance and legibility of product information. The amount of wear damage to the printed substrate depends on transport conditions and may depend on temperature and humidity, time, and many other variables. This practice provides a way to compare the wear resistance of printed materials [...]

What is the method of processing the results of the spectrum data of the differential thermal analyzer

The principle of the differential thermal analyzer is to put the sample to be tested and the reference substance (thermal inert substance) in the furnace body under the same conditions, heating or cooling at the same speed according to the given program, when the heated sample produces changes in physical and chemical properties at different temperatures (such as phase transformation, crystallization structure transformation, crystallization, boiling, sublimation, gasification, melting, dehydration, decomposition, oxidation, reduction… And other reactions), accompanied by heat absorption [...]

ASTM D5749-2017 Standard Specification for Reinforced and Ordinary Tape for Sealing and Fixing

Abstract This specification covers enhanced (Type I) and conventional (type II) paper adhesive tapes for securing and binding paper products and sealing fiberboard boxes. Type I adhesive tape can be stripped (class 1) or not stripped (class 2), while Type II paper adhesive tape, whether it is class A (light load), class B (medium load) or class C (heavy load) can not be stripped. The tape should be made of kraft paper, but it is also recommended to use recycled [...]

ASTM D5750/D5750M-2020 Standard Guide for Width and Length of Pressure Sensitive Tape

Meaning and use 4.1 Compliance with this Guide will reduce misunderstandings between pressure sensitive tape suppliers and users. 4.2 It is recommended to refer to this Guide where the width and length of pressure-sensitive tape is indicated (e.g. in contracts, orders, advertisements and labels). ASTM D5750/D5750M-2020 Standard Guide for Width and Length of Pressure Sensitive Tape Step 1: Scope 1.1 This guide provides guidelines for the width and length of pressure-sensitive tape, including tolerances and labels in inch-pound and SI systems. It is not [...]

ASTM D6123/D6123M-2020 Standard Specification for Pressure Sensitive Tapes for Light Packaging and General Purpose Masks

Abstract This specification covers paper-backed pressure sensitive tape for light packaging and covering. This paper introduces two types of pressure sensitive tape: Type I – corrugated paper backing paper, type II – flat paper backing paper. The materials used in the construction of the tape shall ensure compliance with the specified requirements. The tape shall meet the specified physical requirements. Sample preparation shall be as specified in the appropriate test method. The number of tests per unit of product shall [...]

ASTM D6252/D6252M-2019 “Standard Test Method for Peel Adhesion of Pressure-Sensitive Label Paper at 90° Angle”

Meaning and use 5.1 The test method is a tool for quality assurance. Given a pressure-sensitive label and requiring a minimum or maximum peel adhesion value for that label, test data can be used in conjunction with acceptance criteria. 5.2 Compared to a standard stainless steel panel, this test method can show the relative bonding strength of a given label paper on one or more surfaces with varying materials and textures. For this process, it is acceptable to replace a panel [...]

ASTM D6295/D6295M-2019 Standard Test Method for Distributability of Light Pressure Sensitive Film Strips

Meaning and use 4.1 Pressure sensitive film tape is provided in roll form. In order for such tape to be useful, the strips of tape need to be easily dispensed or cut off from the roll by a cutter on most dispensers. The test method is a way to measure the ease of cutting or distributing the tape. 4.2 The information provided by this test method can be used for material specifications for product design and quality assurance applications. It can [...]

ASTM D6787/D6787M-2017 Standard Specification for Removable Notepads

Abstract This specification covers relocatable colored note paper. Each piece of paper has a pressure-sensitive adhesive strip on the back. Manual steel rollers should be used in the manufacturing of pads, and cylindrical mandrel should be used in the marking test of pads. The minimum average value of the determined paper shall be assembled in the form of a pad. Any individual pad must contain no less than a certain amount of paper. The paper pad and liner should be [...]

ASTM D6788-2017 Standard Specification for Relocatable Pressure Sensitive Marks

Abstract This specification covers relocatable pressure-sensitive marks for marking, tagging and indexing documents, books, journals, etc. The logo covered here consists of a single frosted film covered with adhesive. The non-adhesive label or section at one end of the mark can be easily removed from most surfaces, including paper. The backing should consist of a polyester, polypropylene or polyethylene film, and it should have a clear dull surface on one side that can be written with a pen and pencil. [...]

ASTM D7932-2017 Standard Specification for Printed, Pressure-Sensitive Adhesive Labels for Use in Extreme Circulation Environments

Step 1: Scope 1.1 This specification provides a standard method for testing and measuring the performance characteristics of printed pressure-sensitive adhesive labels for containers, especially containers used in extremely distributed environments (e.g., hazardous materials labels, aerospace, military containers). For the purposes of this specification, an extreme distribution environment is one in which direct exposure to deteriorating chemicals, weather, high/low temperatures, and other environmental and physical factors can reasonably be expected over an extended period of time. 1.2 Units – Values expressed [...]
