ISO (Organisasi Internasional untuk Standardisasi) adalah aliansi global badan standar nasional (badan anggota ISO). Pengembangan standar internasional biasanya dilakukan melalui komite teknis ISO. Setiap lembaga anggota yang tertarik pada subjek di mana komite teknis telah dibentuk memiliki hak untuk diwakili dalam komite tersebut. Organisasi pemerintah dan non-pemerintah internasional yang berhubungan dengan ISO juga terlibat dalam pekerjaan ini. ISO bekerja sama dengan Komisi Elektroteknik Internasional (IEC) tentang segala hal standardisasi kelistrikan.
Prosedur yang digunakan untuk mengembangkan dokumen ini dan yang digunakan untuk pemeliharaan lebih lanjut dijelaskan di Bagian 1 dari ISO/IEC Directive.

ISO 12625-5-2016 “Kertas tisu dan produk kertas tisu – Determination of wet tensile strength – Part 5”
1 Jangkauan
This document specifies a test method for determining the wet tensile strength of tissue paper and tissue paper products after immersion in water using a tensile strength test equipment operating at constant elongation.
Currently, there are two types of tensile strength test equipment on the market, one is placed vertically and the other is placed horizontally. This document applies to both. For vertical tensile strength test equipment, a device fixed to the grip under the tensile strength test equipment, called a finch cup, is used to achieve wetting. For horizontal tensile strength test equipment, the soaking device is placed between the fixtures.
Where impurities and impurities need to be identified, ISO 15755[6] is suitable for these tests in tissue and tissue products.
