1. ibirimwo:
① Ku mpera y’igice c’ugufatanya nibura 25mm, uce ivyerekanwa 3 bishingiye ku nzira y’ubwaguke, ibubamfu, hagati n’iburyo. ubunini bw’icitegererezo ni 100mm×100mm, kandi uruzitiro ruhuye n’uburebure n’uburebure bw’uruzitiro.
② Urupapuro rw'Ivyiyumviro (W1), ukuri kuri 0.001g.
③ Shiraho igipimo mu bukere bwa Maffu bwa 524-593, hanyuma ugiturire mu kiringo c’iminota 15, canke gushika carbide zose zikuweho.
(4) Kwimurira igipimo ku gikoresho co kwumisha maze ugikonjeshe ku bushuhe bwo mu cumba.
Urupapuro rwo gupima impapuro (W2), ukuri kuri 0{2}}001g.
⑥ Guharura: ibirimwo rezin =[(W{1}}W2) /W1]×100%.
2. Igihe:
(1) Ushireko igipimo c’amasegonda nka 20cm×20cm uvuye hagati y’igice c’ugufatanya, ushireko igipimo, ugire ifu y’ibinure vy’igiti igwa mu gipande c’icuma, hanyuma uyishire ku mpapuro zera zisukuye.
② Fata nk’ifu y’igiti y’igiti 20mg maze uyishire hagati y’igipande c’ibara ry’agahama gishushe gushika kuri 171 (±0{3}}℃) imbere y’igihe. Guhagarara igihe ifu ishonze maze uterere igihimba c’amenyo.
③ Haguruke isahani iyo resin igwiriye ku guhagarara kw’igishushanyo c’urutsinga, kandi igihe cagutse ni igihe ca gel{0}}
3. Uguhinduka kw'ukwiruhutsa:
① 4 ibipimo biciwe nibura 5cm kure y’urubibi rw’igice c’ugufatanya. ubunini bw’icitegererezo ni 100mm×100mm, kandi uruzitiro ruhuye n’uburebure bw’uburebure na latitude .

③ Ivyo bipimo biratunganijwe kandi birashirwako umunyu, hamwe n’ivyo kurekura, hanyuma bikashirwa hagati y’ibipande bibiri bitagira ibara.
④ Shira igipande c’icuma n’igipimo kiri mu gipfukisho ku 170℃±2.℃, hanyuma ukagikanda rimwe. Umuvuduko w’igice ni 1.4MPa±0.2MPa, kandi ugigumye mu minota 10.
Kuraho igipimo maze ugikonjere ku bushuhe bwo mu cumba.
⑥ Uvuye hagati y'igicapo φ80mm uruzitiro.
⑦ uburemere bw’ivyo bikoresho (W2), ni ukuri kuri 0.005g.
⑧ Guharura: gukora =[(Wl{1}}W2) /W1]×100%.
