1、Designation: D5267 97 (Reapproved 2017)Standard Test Method forDetermination of Extrudability of Cartridge Adhesives1This standard is issued under the fixed designation D5267; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the yea

2、r of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This test method measures the amount of force neces-sary to extrude an adhesive from a cartridge at a giventemper

3、ature.1.2 The values stated in inch-pound units are to be regardedas standard. The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.3 This standard does not purport to address all of thesafety concerns, if any

4、, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety, health, and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.4 This international standard was developed in accor-dance with internationa

5、lly recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards, Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade (TBT) Committee.2.

Significance and Use4.1 Cartridge adhesives are typically used at job sites in awide variety of temperature ranges. These products may beexposed to cold temperatures, where one of the limit

7、ingapplication factors is whether the product can be extruded fromthe cartridge.4.2 The test method quantitatively measures the force nec-essary to extrude a cartridge adhesive at a given temperature.This provides the formulator with results that can assist informulation development and the end user

8、 with information foruse in selecting a product for general usage.4.3 By measuring (the ease of) extrusion from the cartridge,the test method can also be used as a quality control tool tomeasure the shelf life stability of a product.5. Apparatus5.1 The test fixture is shown in Fig. 1. Details are sh

9、own inFigs. 2-4.3Make the framework from aluminum. Make the rodand plunger combination from steel.5.2 The test fixture is designed to be fitted onto a testmachine capable of measuring compressive strength.6. Conditioning6.1 Before measuring extrudability, condition the cartridgefilled with adhesive

10、until it reaches the desired constanttemperature.7. Procedure7.1 Mount the test fixture to the test machine for stability.7.2 After conditioning the cartridge, cut off enough of thetip, perpendicular to the cartridge, to ensure an inside diameterof14 in. (6.3 mm). If the cartridge has a foil or plas

11、tic liner,puncture it completely to allow passage of the material throughthe orifice. Record the temperature of the adhesive by insertinga thermometer or suitable thermocouple into the cartridge.7.3 Set the crosshead speed to 5.0 in. (127.0 mm) per min oranother acceptable rate.7.4 Activate the mach

12、ine to begin extrusion of the adhesivefrom the cartridge, measure the maximum force necessary tobegin the extrusion process as well as the force necessary tomaintain continued extrusion of the adhesive. The first value isthe force needed to release the plunger from the cartridge. Thesecond value is

13、the force needed to extrude the adhesive fromthe cartridge continuously.1This test method is under the jurisdiction of ASTM Committee D14 onAdhesives and is the direct responsibility of Subcommittee D14.10 on WorkingProperties.Current edition approved Nov. 1, 2017.

Precision and Bias9.1 Precision:9.1.1 Table 1 presents round robin data generated from threelaboratories. Three different cartridge adhesives were used togenerate th

19、e data at two temperatures. The extrudability valueswere based on the average of three separate cartridge values.9.1.2 Repeatability at a given test site for the samplesyielded coefficients of variation from 2 to 18 % for Laboratory1, 1 to 10 % for Laboratory 2, and 2 to 13 % for Laboratory 3,with m

20、ost values in the range of 2 to 11 %.9.1.3 No statement of reproducibility from site to site isavailable at this time.9.2 BiasBias is the difference between the true forcenecessary to extrude an adhesive from a cartridge and the forcemeasured by a repeatable method. Bias arises from the consis-tency

21、 of the adhesive packaged in the cartridge, the method bywhich the plunger is assembled into the cartridge, and insidediameter variations that may exist when the cartridge tip is cut.10.
