Mishnah Mikvaos 10:4: The following require that the water enter into them [when they are immersed]: the knot at the shoulder of an undershirt, and the edge of a sheet [though it] must be spread out, and the head tefilah when it is not tight, and that of the arm when it slides up and down, and the straps of a sandal [used for fastening it]. Clothes that were immersed after being washed, [are not pure] until they bubble [i.e. they are pure once they rest on the water, even if they are still air bubbles between the clothing and the water]; if one immersed them after they were dried, [they are not pure] until they bubble and finish their bubbling [i.e. until they have been fully immersed, with no air bubbles separating them from the water].

אֵלּוּ שֶׁהֵם צְרִיכִים שֶׁיָּבֹאוּ בָהֶן הַמַּיִם, הַקֶּשֶׁר שֶׁבַּפְּרַקְסִים שֶׁבַּכָּתֵף, וְשָׂפָה שֶׁל סָדִין צָרִיךְ לְמַתֵּחַ, וּתְפִלָּה שֶׁל רֹאשׁ בִּזְמַן שֶׁאֵינָהּ חוֹצָה, וְשֶׁל זְרוֹעַ בִּזְמַן שֶׁהִיא עוֹלָה וְיוֹרֶדֶת, וּשְׁנָצִין שֶׁל סַנְדָּל, וּבְגָדִים שֶׁהִטְבִּילָן מְכֻבָּסִין, עַד שֶׁיְּבַעְבְּעוּ. הִטְבִּילָן נְגוּבִין, עַד שֶׁיְּבַעְבְּעוּ וְיָנוּחוּ מִבִּעְבּוּעָן:

Mishnah Mikvaos 10:5: All handles of vessels that are long and will eventually be trimmed should be immersed until the measured place [where they will be trimmed]. Rabbi Yehuda says: [such a vessel is not pure] until one immerses all of it. The [measure for the] chain of a large bucket is four handbreadths, and of a small one, ten; they should be immersed until the area of the [respective] measurement. Rabbi Tarfon says: [it is not pure] until one immerses the entire link [at which the measurement ended]. A rope that is tied to a basket is not considered attached unless one sewed [it on].

כָּל יְדוֹת הַכֵּלִים שֶׁהֵם אֲרֻכִּין וְעָתִיד לִקְצֹץ, מַטְבִּילָן עַד מְקוֹם הַמִּדָּה. רַבִּי יְהוּדָה אוֹמֵר, עַד שֶׁיַּטְבִּיל אֶת כֻּלּוֹ. שַׁלְשֶׁלֶת דְּלִי גָדוֹל, אַרְבָּעָה טְפָחִים, וְשֶׁל קָטָן, עֲשָׂרָה, מַטְבִּילָן עַד מְקוֹם הַמִּדָּה. רַבִּי טַרְפוֹן אוֹמֵר, עַד שֶׁיַּטְבִּיל אֶת כָּל הַטַּבַּעַת. הַחֶבֶל שֶׁהוּא קָשׁוּר בַּקֻּפָּה אֵינוֹ חִבּוּר, אֶלָּא אִם כֵּן תָּפָר:
