DS/ISO 1431-1:1989 硫化或热塑性橡胶.耐臭氧龟裂性.第1部分:静态应变试验

This International Standard is intended for use in estimating the resistance of vulcanized rubbers to cracking when exposed, under static tensile strain, to air containing a definite concen tration of ozone and at a definite temperature in circumstances where the effects of direct light are excluded. Great caution is necessary in attempting to relate standard test results to service performance since the relative ozone resistance of different vulcanizates can vary markedly according to conditions, especially ozone concentration and temperature. In addition, tests are carried out on thin test pieces deformed in tension and the significance of attack for articles in service may be quite different owing to the effects of size and the type and magnitude of deformation. Explanatory notes on the nature of ozone cracking are given in the annex. Methods for determining resistance to ozone cracking under dynamic strain conditions and combined dynamic and static strain conditions will form the subject of Part 2 of this International Standard. A reference method for estimating the ozone concentration will form the subject of Part 3 of this inter national Standard.

DS/ISO 48:1989 硫化橡胶. 硬度的测定(硬度在30-85国际橡胶硬度标度(IRHD)之间)

This International Standard specifies a method for the determination of the hardness of vulcanized rubbers preferably of a hardness range between 30 and 85 IRHD; however, the method may also be used for those rubbers with a hardness between 30 and 95 IRHD. Methods for very hard and very soft rubbers are the subject of ISO 1400 and ISO 1818 respectively; the range of applicability of each is indicated in the following figure :

DS/ISO 3384:1989 硫化橡胶. 在环境温度和高温压缩时应力松驰的测定

Denne standard beskriver to metoder til bestemmelse af faldet i den reaktionskraft, der ud?ves af et pr?velegeme af vulkaniseret gummi, som er blevet sammentrykket til konstant deformation ved fastlagte tids- og temperaturbetingelser. NOTE - De to m?lemetoder A og B giver ikke samme v?rdi af sp?n-dingsrelaxationen og sammenligning af v?rdier opn?et ved de to metoder b?r derfor undg?s. Valget af metode afh?nger af form?let med pr?vningen. S?ledes b?r metode A foretr?kkes til grundl?ggen-de unders?gelser og til form?l, hvor t?thed ved h?je temperaturer er et krav. Metode B b?r foretr?kkes til anvendelsen, hvor cyklisk tem-peraturvariation fra normal til en forh?jet temperatur er et problem.

DS/ISO 7619:1989 橡胶. 用袖珍硬度计测定压痕硬度

1 Denne standard beskriver en metode til bestemmelse af gummis indtrykningsh?rdhed ved hj?lp af lomme-h?rdheds-m?lere af f?lgende typer: a) Shore-h?rdhedsm?ler (Durometer) b) IRHD-h?rdhedsm?ler (IRHD = International Rubber Hardness Degrees) Standarden beskriver to typer Shore-h?rdhedsm?lere. Type A anvendes til gummi med normal h?rdhed, type D til h?rdt gummi. 2 Lomme-h?rdhedsm?lere anvendes prim?rt til inspektion og kan ikke anbefales til specifikation. Specifikation af h?rdhed b?r foretages if?lge de metoder, der er beskrevet i DS/ISO 48, DS/ISO 1400 og DS/ISO 1818. Der kan opn?s st?rre pr?cision ved at fastg?re lomme-h?rdhedsm?leren i en holder. 3 En lignende metode til m?ling af plasts h?rdhed er omtalt I ISO 868, Plastics - Determination of indentation hardness by means of a durometer (Shore hardness).

DS/ISO 2285:1989 硫化橡胶. 在常温和高温下拉伸永久变形的测定

This International Standard specifies a method for determining the tension set characteristics of vulcanized or thermoplastic rubbers. The test is intended to measure the ability of rubbers of hardness within the range 30 to 94 International Rubber Hardness Degrees (IRHD) to retain their elastic properties after extension, at a standard temperature, to a specified strain which is maintained for a specified time at the same or at a specified higher temperature and then released at the standard temperature. NOTE — Three types of test piece are described : strips, strips with enlarged ends and rings. Tests made with different types of test piece do not necessarily give the same value of tension set; neither will tests made at different temperatures necessarily place the materials in the same order of merit.

DS/ISO 3383:1987 橡胶. 为试验目的升温和降至常温以下的通则

This International Standard specifies general requirements for achieving elevated or subnormal temperatures in the testing of rubber and other elastomeric materials. It specifies general principles of the construction and operation of temperature-controlled chambers for conditioning and/or testing. For some tests — for example ageing tests — special procedures, condi-tions or equipment which differ from those specified in this International Standard may be required. In such cases, the requirements should be included in the method of test and supersede the requirements of this International Standard.

This International Standard specifies a method of test for measuring the force required to separate, by stripping, two plies of fabric bonded with rubber, or a rubber layer and a fabric ply bonded together. The method is applicable when the ply surfaces are approxi-mately plane, or are in a cylindrical orientation having an internal diameter greater than approximately 50 mm. The method is not applicable when the ply surfaces contain sharp bends, angles or other gross irregularities which cannot be excluded when cutting out test pieces.

DS/ISO 2856:1987 合成橡胶. 动态试验的一般要求

Denne standard beskriver metoder samt krav til pr?velegemer og pr?vningsudstyr til bestemmelse af elastomerers viskoelastiske parametre ved p?f?ring af periodiske kr?fter eller deformationer af kontrolleret form, frekvens og amplitude. Udtrykket ?dynamiske egenskaber? er her anvendt til at beskrive, hvorledes elastomerer deformeres under betingelser, hvor b?de sp?nding og deformation varierer periodisk med tiden. I denne standard er det forudsat, at der anvendes laboratoriefremstillede pr?velegemer, men de samme principper g?lder normalt for pr?vninger af f?rdige produkter eller prototyper. Standarden indeholder en kort gennemgang af de grundl?ggende begreber og teorier for elastomerers dynamiske egenskaber - med udvalgte litteraturhenvisninger - for at tydeligg?re definitioner og lette fortolkning af data.

DS/ISO 2781:1986 硫化橡胶. 密度的测定

Denne standard angiver to pr?vningsmetoder til bestemmelse af massivt, vulkaniseret gummis densitet. S?danne bestemmelser er vigtige ved kontrol af gummiblandingers kvalitet og ved beregning af den gummimasse, der kr?ves ved fremstilling af et givet volumen vulkanisat. Denne standard d?kker ikke bestemmelse af gummis relative densitet. Denne er forholdet mellem massen af et givet volumen gummi og massen af et tilsvarende volumen rent vand ved en given temperatur. I denne standard er bestemmelsen foretaget ved observation af tyngdekr?fter under forskellige forhold, men disse kr?fter er for nemheds skyld udtrykt i masseenheder.
