Figure 8: NIST HB44, Table N.3.2: Number of sample weights per test (referred to in OIML documents as “test weighings”)
Special endurance tests for ACWs in the USA
Whereas for reasons of occupational safety OIML R 51
performs all influence factor tests in accordance with
Chapter 6.4.5 only up to a maximum load of 20 kg in
automatic operation (and permits static tests for loads
in excess of 20 kg in non-automatic operation), all tests
in the United States are performed with the entire
weighing range in automatic operation.
This comparative strictness is due to other factors as
well. In addition to HB44, ACWs in the United States
also have to fulfill the requirements of NCWM
Publication 14 (Pub 14) (see Figure 8). This publication
includes a permanence test, an uninterrupted 100-hour
endurance test in automatic operation without a single
stop of the conveyor system. After this test is concluded,
the accuracy of the ACW in automatic operation is
checked again. During these 100 hours, the conveying
speed is at least 80 % of the maximum speed. The
packages moved across the conveyor belt and weighed
dynamically have to weigh at least 75 % of the maximum
capacity (Max) of the ACW. Furthermore, no large gap
may be present between two successive packages,
forcing the ACW to have weight applied to it as
continuously as possible. In the case of fast ACWs,
several hundred thousand packages are weighed during
this test. Inferior conveyor systems which wear out
quickly will not survive this endurance test.

tes ketahanan khusus untuk ACWs di USA
Sedangkan untuk alasan keselamatan OIML R 51
berkinerja semua faktor pengaruh tes sesuai dengan
Bab 6.4.5 hanya sampai beban maksimum 20 kg di
operasi otomatis (dan izin tes statis untuk beban
lebih dari 20 kg dalam operasi non-otomatis), semua tes
di Amerika Serikat dilakukan dengan seluruh yang
berat rentang operasi otomatis.
Teliti komparatif Hal ini disebabkan faktor lain seperti
juga. Selain HB44, ACWs di Amerika Serikat
juga harus memenuhi persyaratan NCWM
Publikasi 14 (Pub 14) (lihat Gambar 8). Publikasi ini
meliputi tes permanen, sebuah 100-jam tanpa gangguan
uji ketahanan dalam operasi otomatis tanpa satu
berhenti dari sistem conveyor. Setelah tes ini disimpulkan,
keakuratan ACW dalam operasi otomatis
diperiksa lagi. Selama 100 jam ini, menyampaikan
kecepatan setidaknya 80% dari kecepatan maksimum. The
paket melintasi ban berjalan dan ditimbang
secara dinamis harus mempertimbangkan setidaknya 75% dari maksimum
kapasitas (Max) dari ACW. Selanjutnya, ada kesenjangan besar
dapat hadir antara dua paket berturut-turut,
memaksa ACW untuk memiliki berat badan diterapkan sebagai
terus mungkin. Dalam kasus ACWs cepat,
beberapa ratus ribu paket ditimbang selama
tes ini. Sistem conveyor rendah yang aus
cepat tidak akan bertahan uji ketahanan ini.
