Determining the bond strength of pressure-sensitive tapes and laminated release coatings.
(often referenced as DIN 53357:1982-10) is a German industrial standard used to determine the adhesion strength between layers of plastics sheets, artificial leather, and similar sheet materials. It is specifically used as a Trennversuch der Schichten (separation test of layers) to evaluate how well a coating or laminated layer sticks to its substrate. Key Characteristics din 53357 pdf
For most international projects, yes. However, some German OEMs (Volkswagen, BMW, Mercedes) still explicitly request DIN 53357 in their test specifications. Always check your customer’s requirement. Key Characteristics For most international projects, yes
Attempts to find a direct international (ISO) replacement have been problematic. Standards like DIN EN ISO 2411 (for rubber-coated textiles) and DIN EN ISO 11339 (for adhesives) are deemed unsuitable because they specify different sample widths and do not address the peel angle crucial for film adhesion measurements. As a result, many industries continue to use the withdrawn DIN 53357 in their internal specifications. Attempts to find a direct international (ISO) replacement
Testing the bond between layers in automotive interior laminates.
For modern operations, newly established laboratories, or manufacturers looking to acquire international compliance certification, moving away from legacy files is standard practice. The formal replacement standard is ( Rubber- or plastics-coated fabrics - Determination of coating adhesion ). Critical Differences to Note
