This Standard replaces GB/T 2792-1998 Test method for peel strength of pressure-sensitive tape at 180° angle. Compared with GB/T 2792-1998, the major technical changes are as follows. — MODIFY the standard name to Measurement of peel adhesion properties for adhesive tapes; — DELETE the reference standard JB/T 7499-1994 Waterproof abrasive paper (SEE Chapter 2 of 1998 edition); — MODIFY the definition of the term “peel strength” (SEE Section 3.1 in Chapter 3 of 1998 edition); — ADD the term “test assembly” (SEE Section 3.2 of this Standard); — ADD the term “roughness average” (SEE Section 3.3 of this Standard); — MODIFY the types of cleaning agents (SEE Section 5.2.2 of this Standard, Section 5.3.1 of 1998 edition); — ADD the sample cutting method (SEE Section 5.3.1 of this Standard); — MODIFY the requirements of standard test plates (SEE Section 5.3.3 of this Standard, Section 5.2 of 1998 edition); — MODIFY the dimensions and mass of the roller (SEE Section 5.3.4.1 of this Standard, Sections 4.1.1 and 4.1.3 of 1998 edition); — MODIFY the standard test conditions for laboratory (SEE Section 5.4.1 of this Standard, Section 6.2 of 1998 edition); — MODIFY the standard sample dimensions (SEE Section 5.4.2 of this Standard, Section 5.1 of 1998 edition); — ADD the cleaning method of steel plates (SEE Section 5.5.2.1 of this Standard); — MODIFY the number of press rolls (SEE Section 5.5.3.1 of this Standard, Section 7.3 of 1998 edition); — MODIFY the sample preparation time and the dwell time before testing (SEE Section 5.5.3.1 of this Standard, Section 7.4 of 1998 edition); — ADD the test method of peel strength for adhesive tapes from their own backings at an angle of 180° (SEE Chapter 6 of this Standard); — ADD the test method of peel strength for adhesive tapes from adhesion- resistant materials at an angle of 180° (SEE Chapter 8 of this Standard); — ADD the test method of peel strength for adhesive tapes at an angle of 180° and low temperature (SEE Annex A of this Standard); — ADD the test method of peel strength for adhesive tapes at an angle of 90° (SEE Annex B of this Standard). This Standard was redrafted by reference to ISO 29862.2007 Self adhesive tapes - Determination of peel adhesion properties after modification. Compared with ISO 29862.2007, this Standard has made some structural adjustments. The contrast table for the section numbers of this Standard and ISO 29862.2007 is listed in Annex C. There are technical differences between this Standard and ISO 29862.2007. The clauses involved in these differences have been indicated on the outer margin thereof by using the vertical single line (∣). The list for technical differences and corresponding causes has been given in Annex D. This Standard has also made the following editorial modifications to ISO 29862.2007. — MODIFY “this International Standard” as “this Standard”; — MODIFY the unit of peel strength from “N/10mm” to “N/cm”. This Standard was proposed by the China Petroleum and Chemical Industry Federation. This Standard shall be under the jurisdiction of the National Technical Committee for Standardization of Adhesives (SAC/TC 185). Drafting organizations of this Standard.

The previous released editions substituted by this Standard are as follows. — GB/T 2792-1981 and GB/T 2792-1998. Measurement of peel adhesion properties for adhesive tapes1 ScopeThis Standard specifies a series of test methods for the peel strength of adhesive tapes. This Standard is applicable to the determination of peel strength of adhesive tapes, and is also used for controlling the quality of adhesive tapes.2 Normative referencesThe following documents are essential to the application of this document. For dated references, only the editions with the dates indicated are applicable to this document. For undated references, only the latest editions (including all the amendments) are applicable to this document. GB/T 2523-2008 Measuring method of surface roughness and peak count for cold-rolled metal sheet (strip) GB/T 3280-2007 Cold-rolled stainless steel plate, sheet and strip3 Terms and definitionsThe terms and definitions defined in GB/T 22396 and the following ones are applicable to this document. It refers to the force required to peel a unit width of adhesive tape from a specific adhesive surface at a specified angle and speed, in unit of N/cm. It refers to the arithmetic mean deviation of the roughness profile, which is the arithmetic mean value of the absolute value of the roughness profile offset within the sampling length.4 ClassificationAccording to different objects, temperatures and peel angles of the adhesion of adhesive tapes, the methods in this Standard can be divided into the following categories.5 Method 1.Test method of peel strength for adhesive tapes from stainless steel at an angle of 180°An appropriate test piece cutter shall hold two single edge razor blades in parallel planes a precise distance apart, to form a cutter of exact specimen width; two cutters, 12mm and 24mm cutting widths, shall be available or appropriate alternatives which will not cause edge damage. If this testing condition cannot be maintained, the closest possible condition shall be used, and the revised condition shall be indicated in the report.6 Method 2.Test method of peel strength for adhesive tapes from their own backings at an angle of 180°Any suitable clean rigid steel plate with a width of 50mm, length of 125mm and thickness of not less than 1.1mm.7 Method 3.Test method of peel strength for double- sided and transfer adhesive tapes from stainless steel at an angle of 180°APPLY a length of double-sided or transfer adhesive tape to a steel plate. As described in Section 5.4.4, PREPARE a 300mm long test piece to be tested. FOLD 12mm at one end, adhesive surface to adhesive surface to form a tab.8 Method 4.Test method of peel strength for adhesive tapes from adhesion-resistant materials at an angle of 180°APPLY a length of double-sided adhesive tape to the steel plate. CLAMP one end of the steel plate in one jaw of a tensile testing machine. After the movable jaw is started in motion, DISREGARD the values obtained while the first 25mm of adhesive tape is peeled. ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al.
