Описание (английский):

ISO 7663:2014 specifies the following: - physical and chemical tests on raw rubbers; - standardized materials, a standardized test formulation, and the equipment and processing methods for evaluating the vulcanization characteristics of all types of halogenated isobutene-isoprene rubber (BIIR and CIIR).

Abstract

Overview

Key topics and technical requirements

Scope: Physical/chemical tests on raw BIIR/CIIR and methods for evaluating vulcanization characteristics and vulcanizates.
Sampling and preparation: Follow ISO 1795 for lot sampling and laboratory sample preparation.
Raw-rubber tests:
- Mooney viscosity: Determination as ML(1+8) at 125 °C (ISO 289-1).
- Volatile matter: Hot‑mill method (ISO 248-1) or thermogravimetric method (ISO 248-2).
- Ash content: According to ISO 247 (method A or B).
Standard test formulation (parts by mass): BIIR/CIIR 100, Stearic acid 1, Carbon black 40, Zinc oxide 5 (total 146). Use specified reference materials (e.g., ISO 8312 stearic acid, ISO 9298 zinc oxide).
Mixing procedures: Two options with a preference for laboratory internal mixer per ISO 2393:
- Method A: Mill mixing (detailed roll temperatures, timings, and batch handling).
- Method B: Single‑stage mixing with a laboratory internal mixer (batch sizing, rotor speeds, temperature limits - final batch ≤120 °C).
- Note: Carbon black conditioning (125 °C for 1 h) and moisture control are critical because zinc‑oxide‑activated vulcanization is moisture sensitive.
Vulcanization characterization (curemeter tests):
- Oscillating‑disc curemeter (ISO 3417): measure ML, MH, ts1, tc, t′50 and t′90 at die temperature 160 °C and oscillation frequency 1.7 Hz.
- Rotorless curemeter (ISO 6502): equivalent parameters F L, F HR etc., same test frequency and die temperature.
Tensile testing: Vulcanize sheets at specified times (15, 30, 45 min at 150 °C), condition per ISO 23529, and measure stress‑strain per ISO 37.
Reporting and precision: Test report requirements and precision data are specified.

Applications and users

Who uses it: Rubber manufacturers, compounders, quality control laboratories, R&D teams, material suppliers and specification engineers.
Practical applications:
- Compare BIIR/CIIR batches and suppliers.
- Optimize mixing and curing recipes for halogenated butyl elastomers.
- Provide reproducible cure and mechanical data for product specifications, performance validation and quality assurance.
- Support formulation development for automotive, hose, sealing, and impermeable‑liner applications where BIIR/CIIR properties are required.
