Kommentar zu Parah 11:2

כל הספק טהור לתרומה – any matter of doubt that if it that same doubt appeared in the heave-offering, the heave offering is pure, if it appeared in a similar manner in the purification offering, it is pure (see also Tractate Taharot, Chapter 4, Mishnah 2).

Anything that is doubtfully pure in the case of terumah is regarded as clean in the case of the hatat waters. There are cases in which terumah is doubtfully pure/impure (we shall learn of these in Toharot (next tractate) 4:2. In these cases the terumah must be burned. If the same type of doubt occurs with regard to hatat waters, they remain pure.

וכל התלוי לתרומה – and an doubt that if it appeared in heave-offering where we suspend it we don’t eat neither do we burn it, if it appeared in a similar manner in the purification offering, the ashes should poured out or the mixed mater. And in the Tractate Taharot, in the Chapter “He Who Threw Something Unclean”/הזורק תרומה (Chapter Four), we taught to them regarding a doubt of something pure and on a doubt that is upon his hands, we suspend it regarding heave-offering (see Tractate Taharot, Chapter 4, Mishnah 5).

Anything that is "suspended" where terumah is concerned, the hatat waters are poured out. If clean things were handled on account of it, they must be "suspended." There are cases in which the terumah is "suspended" meaning it is neither burned nor eaten. If the same type of issue occurs with hatat waters, the waters must be poured out. If these hatat waters that were supposed to be poured out were used to purify a person, and then he touched clean food, this too must be "suspended." The food cannot be eaten or burned, as if it was terumah.

ואם עשו על גביו טהרות (and if they prepared clean things on account of it) – if e sprinkled with these ashes that were defined in doubt that was suspended for heave-offering, and made clean things on account of it through that sprinkling, they suspend those pure things, and they don’t eat nor burn them.

Wooden lattice work is clean in respect of holy food, terumah, and the hatat waters. Wooden lattice work is not considered to be a vessel, nor is it made for sitting or lying upon. Therefore, it is not considered impure with regard to matters of holy food, terumah or hatat waters.

הרפפות (cases of Levitical uncleanness arising from vibrations caused by unclean persons) – like a kind of net-work/mat of wood.

Rabbi Eliezer says: Loosely connected wood is unclean in respect of hatat waters. According to Rabbi Eliezer, occasionally a person will sit on a configuration of loosely connected wood. Since people sit on this wood work, one who does is impure with regard to the preparation of hatat waters. That is to say, a person who touches this wood will be invalid, even if the wood has not been defiled. There are other interpretations of what "loosely connected wood" is. Albeck explains that it is the same thing referred to in section three, and that Rabbi Eliezer disagrees with that opinion

טהורת לקודש לתרומה ולחטאת – because they are not vessels and they are not suitable/appropriate for treading [by someone with a flux or a woman after childbirth].

והרעדות (indirect contact through vibrations) – pieces of wood/boards that are not attached well to each other, and when a person leans upon them, they vibrate/tremble and shaking.

טמאות לחטאת – sometimes when a person sis upon them and they are appropriate to become defiled though sitting. But the Halakha is not according to Rabbi Eliezer.
