ULASAN UMUM BAGI DRAF-DRAF MALAYSIAN STANDARD YANG SEDANG DIBANGUNKAN BAGI TEMPOH 1 DISEMBER 2012 – 31 JANUARI 2013

Dengan segala hormatnya perkara di atas adalah dirujuk. Bersama sama ini disertakan senarai draf-draf Malaysian Standard yang sedang dibangunkan seperti di Lampiran A dan pindaan MS (MS Amendment) untuk ulasan umum. Draf-draf dan Malaysian Standard tersebut adalah mengenai pelbagai barangan, prosesproses dan tatasusila amalan dalam pelbagai bidang industri yang dibangunkan di bawah Jawatankuasa Standard Perindustrian (ISC) di SIRIM Berhad. Jadual pecahan jumlah draf-draf dan Malaysian Standard tersebut mengikut ISC disertakan di lampiran. Penyediaan draf-draf Malaysian Standard serta pengesyoran bagi penarikan balik Malaysian Standard tersebut telah dibuat oleh jawatankuasa berkaitan yang ditubuhkan di SIRIM Berhad yang diwakili oleh pihak industri, kementerian, agensi-agensi kerajaan, institusi pengajian tinggi dan orang perseorangan yang pakar dalam bidang berkenaan. Sehubungan dengan itu, pihak SIRIM Berhad mengalu-alukan sebarang ulasan ke atas draf-draf dan penarikan balik Malaysian Standard tersebut. Bagi mereka yang bukan ahli bagi mana-mana ISC, draf-draf Malaysian Standard yang diterima pakai (adopted) dari standard ISO/IEC, ASTM dan EN boleh diperolehi dengan bayaran seperti tertera. Bayaran boleh dibuat secara tunai/cek dengan tambahan 10% bagi bayaran pos kepada SIRIM Berhad. Tuan/puan juga boleh menyemak dokumen tersebut secara percuma dengan datang sendiri ke Pusat Pengurusan dan Penyelidikan Standard, Tingkat 2, Bangunan 3, SIRIM Berhad. Draf-draf untuk ulasan umum boleh diperolehi daripada: SIRIM Berhad (u.p.: Pusat Pengurusan dan Penyelidikan Standard) Tel : 603-5544 6362 / 603-5544 6328 Fax : 603-5510 8830 / 5544 6348 E-mail : [email protected] Website: www.sirim.my/web/srmc/public-comment

Dimaklumkan juga bahawa draf-draf Malaysian Standard tersebut masih dalam peringkat penyediaan dan tertakluk kepada pindaan dan bukan digunakan untuk rujukan rasmi sebagai Malaysian Standard. Memandangkan draf-draf tersebut juga adalah hakcipta organisasiorganisasi yang berkenaan seperti STANDARDS MALAYSIA, ISO/IEC, ASTM dan CEN, tuan/puan adalah dilarang daripada membuat salinan dan mengedarkannya kepada pihak lain. Semua ulasan hendaklah sampai ke SIRIM Berhad selewat-lewatnya pada:

31 JANUARI 2013

Kami juga berharap untuk mendapat kerjasama daripada pihak tuan/puan agar dapat membuat pautan laman sesawang organisasi tuan/puan kepada laman sesawang kami di www.sirim.my/web/srmc/public-comment bagi tujuan pemberitahuan kepada organisasi tuan/puan. Kerjasama serta sokongan tuan/puan dalam perkara ini diharap akan dapat memajukan lagi aktiviti-aktiviti standardisasi negara kita. Sekian terima kasih.

If the unit manufacturer’s recommended minimum temperatures are greater than those specified in Table 3, then those may be used in lieu of the specified temperatures. b

Corrected for fouling factor allowance by using the calculation method described in B6.3.

c

The flow rates are to be held constants at full load values for all part-load conditions.

d

For part-load entering condenser water temperatures, the temperature should vary linearly from the selected EWT at 100 % load to 80.0 F at 50 % loads, and fixed at 80.0 F for 50 % to 0 % loads. e

For part-load entering air dry bulb temperatures, the temperature should vary linearly from the selected EDB at 100 % load to 78.0 F at 33 % loads, and fixed at 78.0 F for 33 % to 0 % loads. EDB = entering air dry-bulb temperature LWT = leaving water (liquid) temperature EWT = entering water (liquid) temperature FFA = fouling factor allowance
