Shenhai FRAGOR-Probatur
In bt4 rating in CREPITUS-probationem apparatu duo prima parametri indicat. Accedit, the 'b'’ in bt4 denotet Classis IIb, significans usum in non-fodienda occasus.

B
The 'B'’ indicat Gas gradu in elit, determinari per gradus referat experimentalem ". Haec divisio imprimis rationem reddit maximos hiatus per quos vapores transire possunt et eorum minimi impetus ignitionis. Generatur in tres gradus: Classis A, B, et C *. Class A ambitus relative tutum, Classis B ancipitia magis, et Class C periculosa, etsi minus communi. Classis C explosio-probatio instrumenti in utroque genere A et B ambitus convenit, Classis B apparatu aptus ad Class A occasus, et classis A apparatu solum pro Class A ambitibus. Itaque, Classis B plerumque vexillum gradu ad explosionis apparatum in foro. Hierarchia inter has classes est Classis C > Classis B > Classis A.
T4
T4 est temperatus genus in elit, secundum vapores’ relativa ignitio puncta. Superiores temperaturas classificationes necessarias inferiores temperaturae operating et instrumenti duriori specifications. Hae classes formandae sunt ad signa productionis specifica, lectio armorum explosione-probationem requirit ut ipsa environmental temperatus campester aequare ". T4-aestimavit apparatu ordinatur ad temperaturis vndique a agunt 135 ad CC°C.
In bt4 CREPITUS-probationem rating est procreatus, dum magna usability et latis lectio applicabiles ambitus.
